Answer:
i think it is oxygen, heat, steam heat.
Explanation:
Which statement is correct? Carbon dioxide diffuses from the alveoli into surrounding capillaries. In the blood, oxygen is bound to hemoglobin, a protein found in red blood cells. Oxygen is released from the mitochondria as a product of cellular respiration. As oxygen diffuses from the lungs into capillaries, blood becomes deoxygenated. Oxygen diffuses from large blood vessels into the body's cells.
Answer:
In the blood, oxygen is bound to hemoglobin, a protein found in red blood cells.
Explanation:
The blood contains a protein called hemoglobin. This protein has the important use of ensuring oxygen is bound to the blood for distribution to other parts of the body. The oxygen helps in the vital functioning and metabolism of the various body parts.
This explains why In the blood, oxygen is bound to hemoglobin, a protein found in red blood cells Is the right choice.
How would you describe the effect of a 1°C increase of temperature on the biodiversity of the habitat in terms of number of populations and number of individuals in the populations? Use evidence from your graph and table to support your answer.
Answer:
Population of some organisms increases and some decreases with the increase in temperature.
Explanation:
The population of certain species such as Nassuar grouper, Spotlight parrotfish and Queen angelfish increases with the increase in temperature while some species such as yellow tail snapper, sponges and algae decreased in population with the increases in temperature. This is because some species needs high temperature so increase in temperature increases the population while some species needs low temperature so high temperature kill them and population is decreased.
Answer:
The population of some creatures increases while the population of others falls as the temperature rises. Certain species, such as Nassuar grouper, Spotlight parrotfish, and Queen angelfish, see an increase in population as the temperature rises, whereas others, such as yellow tail snapper, sponges, and algae, see a fall in population as the temperature rises. This is because some species require high temperatures, so a rise in temperature increases their number, but others require low temperatures, so an increase in temperature kills them and decreases their population.

A woman consumes 500 grams of carbohydrate, 30 grams of protein, and 75 grams of fat in one day. How many total kcalories has she taken in, and how many and what percentage of kcalories are from carbohydrate, protein, and fat?
A. Total kcalories:
B. Percentage of kcalories from carbohydrate:
C. Percentage of kcalories from protein:
D. Percentage of kcalories from fat:
Answer and Explanation:
The computation is shown below:
A. For Total k. calories
= (Number of grams in carbohydrates × 1 gm of carbohydrates) + (Number of grams in protein × 1 gm of proteins) + (number of grams in fat × 1 gm in fat)
= (500 × 4) + (30 × 4) + (75 × 9)
= 2000 + 120 + 675
= 2795 k. calories
b. As we know that
1 gm of carbohydrates = 4 k. calories
So, for 500 grams it would be
= 500 × 4
= 2000 k. calories
Now the percentage is
= Total grams in carbohydrates ÷ Total kcalories
= 2000 ÷ 2795
= 0.72
= 72%
C. As we know that
1 gm of proteins = 4 k. calories
So, for 40 grams, it would be
30 × 4 = 120 k. calories
Now the percentage is
= Total grams in protein ÷ Total kcalories
= 120 ÷ 2795
= 0.043
= 4.3%
D. As we know that
1 gm of fat = 9 k. calories
So for 75 grams, it would be
75 × 4 = 200 k. calories
So, the percentage is
= Total grams in fat ÷ Total kcalories
= 200 ÷ 2795
= 0.072
= 7.2%

In order for translation to occur: Please choose the correct answer from the following choices, and then select the submit answer button. transcription must be occurring simultaneously. there must be large numbers of free amino acids present in the cytoplasm. the DNA must produce large numbers of free amino acids. replication must be occurring simultaneously. the nuclear membrane must first dissolve
Answer:
there must be large numbers of free amino acids present in the cytoplasm
Explanation:
In order for translation to occur, there must be a large number of free amino acids in the cytoplasm.
These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.
During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.
Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.

PLEASE HELP! An original dna strand has the following base sequence: taggtaact What base sequence would be produced through dna replication? A B C D
The correct answer is D. ATCCATTGA
Explanation:
In DNA, there are four nucleobases: guanine (G), thymine (T), adenine (A), and cytosine (C). Additionally, these bases form pairs as guanine aligns with cytosine, and adenine aligns with thymine. This base pairing principle is essential in replication because complementary bases are required to create a new strand or replicate DNA.
According to this, if the sequence is TAGGTAACT, the complementary sequence is ATCCATTGA because, in this way, each base matches with the complementary base.
T (Thymine) is paired with A (Adenine)
A (Adenine) is paired with T (Thymine)
G (Guanine) is paired with C (Cytosine)
G (Guanine) is paired with C (Cytosine)
T (Thymine) is paired with A (Adenine)
A (Adenine) is paired with T (Thymine)
A (Adenine) is paired with T (Thymine)
C (Cytosine) is paired with G (Guanine)
T (Thymine) is paired with A (Adenine)
What usually happens to the host’s DNA during the lytic cycle? It is destroyed. It is integrated with the viral DNA. It becomes a provirus. It is deactivated.
Answer:
It is destroyed
Explanation:
The lytic cycle of the viral life cycle is characterized by the destruction of the host's DNA. The infecting phage gains entrance into the host's cell synthesizes proteins that break down the host's DNA, and then utilizes its own DNA as the cellular DNA.
From there on, the phage takes over the cell's genetic mechanisms and utilizes it in the synthesis of the necessary proteins to manufacture new infecting structures.

Explain why eating a meal with too much salt leads to production of small volume of concentrated urine.
Answer:
the urine is burned up by salt which will evaporate
Answer:
Eating a meal with too much salt leads to a decrease in the water potential of blood. This fall in water potential is detected by the osmoreceptors in the hypothalamus (in brain). The hypothalamus stimulates the pituitary gland to release antidiuretic hormone (ADH). The walls of the collecting duct in the kidney become more permeable to water, hence, a greater proportion of water is reabsorbed from the urine back into the blood by osmosis.
As a result, a small volume of concentrated urine is formed.

Explain the basic steps in the first half of photosynthesis. Describe the movement of electrons and the importance of hydrogen ions in developing a proton gradient that allows for ATP production.
Answer:
This simply refers to photolysis of water.
Explanation
Generally,two steps are involved in photosynthesis.
The light dependent stage or light reaction,(which is the first part of photosynthesis,
The light independent stage (which is the second part.)
The light independent reactions involved the trapping of sunlight by the photo systems, in the leaves,and the splitting of the water molecules by sunlight.
H20 + Sunlight → 1/2H+ +2 e- +1/2 O2.
The movement of electron can be cyclic or non cyclic photophosphorylation, In Cyclic, photo system 1 absorbs the electrons and pass these to the primary pigments in the leaves. This excited the electron in chlorophyll molecule to higher energy levels , The electron emitted from the leaves is by a process called by photoactivation The emitted electron do not return to the photosystems,rather they are pick up by the primary electron acceptors and returned to the chlorophyll molecules by electron carriers,NADP.
During this process Energy is released for ATPase synthase of ATP for phosphorylation of ADP with phosphate,
In Non-cyclic photophorylation,photosystem I and II absorbs the electrons as Z-scheme movement of electrons.,Photoactivation of chlorophyll takes place as in the Cyclic.The primary electron acceptors takes the excited electrons to move along the chain of electron carriers.This makes the photosystems positively charged.
Hence to regain stability the primary pigment of photo system 1 takes electrons from photosystem II.To replace its lost electrons, P II takes electrons from the photolysis of water.ATP is generated as the carriers molecules transport electrons from the energy produced.
The hydrogen ions is used for the production of electrochemical gradients,which supplies the energy used by the ATPase synthase for the ATPs production.The process is called chemiosmosis. It involved the transports of H atoms by NADPH into the stroma,and the splitting of these into protons and electrons,The electrons form ETC,which forms the PMF.The latter pumped protons into the thylakoid membrane,and as this returns it generate the electrochemical gradient.
The ATP is used in the Calvin Cycle for CHO,proteins productions,
Assume that the point mutation and deletion mutation are not in overlapping regions of the phage genome. What phage recombinants would you expect if a crossing-over event occurred between the regions of the two mutations?
Answer:
A recombinant phage containing both mutations.
Explanation:
A recombinant organism is produced by recombination, which is a genetic phenomenon associated with the repair of double-strand breaks in DNA. In genetic research, recombinant organisms are used to investigate target gene expression. The process of DNA repair may be associated with two different pathways: homologous recombination (HR) and non-homologous end-joining (NHEJ). In this case, the recombinant phage contains no overlapping mutations (i.e., both deletion and point mutations), thereby carrying the desired genetic combination.

List some characteristics of each type of seismic wave. Include what type of material (solids, liquids, or both) each can travel through. Primary wave: Secondary wave: Love wave: Rayleigh wave:
Answer:
The primary wave or the P wave is the fastest kind of seismic wave. These waves can travel through the fluids like the liquid or the water layers of the Earth, and solids rocks. It pulls and pushes the rock it moves through similar to the sound waves that pull and pushes the air. These waves are also called compressional waves, due to the pulling and pushing they do.
The secondary wave is also known as the S wave is slower in comparison to a P wave, and possess the tendency to move through the solid rock, however, not through any kind of liquid medium. The characteristic of the S wave helped seismologists to conclude that the outer core of the Earth is a liquid. The S waves help in moving the particles of rock side to side perpendicular to the direction of the wave or up and down.
The Love wave and Rayleigh waves are the two kinds of surface waves. These waves possess lower frequency in comparison to the P and S waves. Of the surface waves, the Love waves are the fastest surface wave and move the ground from side to side.
On the other hand, a Rayleigh wave rolls around the ground similar to the rolling of the waves across an ocean or a lake. Both these waves only travel through a solid medium.
Read the passage from “Part of the Stew.” On the morning of January 8, 1815, the Redcoats made their attack. Mama and I woke up to the sound of it. It was like thunder that rolled on and on, and we held hands as we thought of Pa and our friends. Then, suddenly, everything was silent. It felt like forever as we waited for news. Finally, word came around that the British had raised the white flag of surrender.

Which of the following is false? Unselected Under normal conditions, blood PO2 affects breathing only indirectly. Unselected Changes in arterial pH resulting from CO2 retention or metabolic factors act through the peripheral chemoreceptors. Unselected When arterial PO2 falls below 60 mm Hg, it becomes the major stimulus for respiration. Unselected Oxygen levels are the primary stimulant of respiration.
Answer:
The sentence that says: Blood PO2 affects respiration only indirectly, IT IS FALSE, since the partial pressure of oxygen gas together with carbon dioxide are factors that DIRECTLY affect respiration.
The sentence that says: Unselected changes in arterial pH as a result of CO2 retention or metabolic factors act through peripheral chemoreceptors. It is FALSE, since the central chemoreceptors together with the peripheral ones can detect the metabolic acidosis generated by the CO2 retention, this is how the CNS receptors capture the CO2 that crosses the blood-brain barrier and stimulates hyperventilation to compensate for this phenomenon and increase the plasma concentrations of partial oxygen pressures.
The sentence that says: in selecting When arterial PO2 falls below 60 mm Hg, it becomes the main stimulus for breathing, IT IS FALSE, since it not only encourages ventilation to promote oxygenation but also activates the renin-angiotensin-aldosterone in order to recover blood volume and thus achieve adequate blood pressure.
In addition, hypovolemia triggers tachycardia and weakening symptoms, which is why the drop in blood pressure is not the main stimulus for breathing.
Explanation:
Breathing is promoted by muscle contraction, medium and high temperatures (that is, in hot or hot climates), partial concentrations of oxygen and carbon dioxide both in the atmosphere and in our blood, and in situations of systemic imbalances such as metabolic acidosis or alkalosis.

Areas on the moon called maria Select one: a. are seas of water. b. consist of basaltic lava. c. formed a million years ago. Clear my choice
Areas on the moon called maria consists of basaltic lava. Option B is correct.
The areas on the moon called maria are not actually seas of water, as option a suggests. Instead, they are large, dark, flat areas on the moon's surface. These areas were formed by ancient volcanic activity.
Maria are made up of basaltic lava, which is a type of lava that is low in viscosity and can flow easily. When volcanic eruptions occurred on the moon in the past, this lava flowed out onto the surface and covered large areas, creating the maria.
These volcanic eruptions and the formation of the maria took place billions of years ago, not just a million years ago as option c suggests. They are remnants of the moon's early history when volcanic activity was more prevalent.
