Explain why eating a meal with too much salt leads to production of small volume of concentrated urine. ​

Answers

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.

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:

Answers

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%

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.

Answers

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,

In captivity, tigers and lions have been known to interbreed and produce hybrids, known as ligers. Why does this NOT make them the same species, according to the biological species concept

Answers

Answer:

Explanation:

A cross between a tiger and a lion will produce an hybrids. During fertilization it has been observed that both the father and the mother contributes equally to the genetic makeup of the offspring this therefore will make the liger have 50%gene from the tiger and 50% gene from the lion which is different genetic makeup from the parents.

Since the parents are of two different species the offspring will always be of a different species because its makeup is genetically different from the two parents it is a combination of two species forming a new species.

If the parental species are the same i.e two lion or tiger the offspring will be of the same species but a combination of the parental gene.

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?

Answers

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:

Answers

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.

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

Answers

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)

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.

Answers

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.
