Answer: Without plants there would be no OXYGEN on earth. Plants take all the AIR we breathe and all the FOOD we eat. Plants take energy from the SUN and make their own food in the form of GLUCOSE. Plants take in CARBONDIOXIDE from the air, and give off OXYGEN.
Explanation:
Plants are autotrophs which means they are producers. Green plants are able to manufacture their own food through the process known as PHOTOSYNTHESIS.
This process, photosynthesis, is not only important to plants themselves but also to animals and humans, which depends on the products which is oxygen and glucose (food).
The main features of photosynthesis includes:
--> photosynthesis takes place in the chloroplasts of plant cells, in the presence of SUN ( solar energy).
--> The raw materials of the process are the low - energy containing inorganic compounds, for example, the CARBONDIOXIDE and water.
--> The final products of the process are high energy containing sugars (GLUCOSE). Oxygen is given off as a waste product which makes up the AIR we breathe.
--> The energy needed to drive this anabolic process comes from the sunlight absorbed by chlorophyll, the green pigment found in chloroplasts. While the glucose produced are converted to starch and stored in the plant storage organs such as roots, stems, fruits and seeds.

Which phase of mitosis is shown at the
letter 'A'?
A Interphase
B Prophase
C Metaphase
D Anaphase
E Telophase
A newly created cell and its nucleus go through a series of modifications known as prophase and interphase in order to prepare for cell division. It is also known as the preparatory phase.
Exists the M phase?When a cell is in the M phase, it divides, first through nuclear division (mitosis), then through cytoplasmic division (cytokinesis). The DNA is replicated in the earlier S phase, and cohesins keep each replicated chromosome's two copies (known as sister chromatids) bound to one another.
Is the M phase the longest phase?Prophase is the first and longest phase of mitosis. Chromatin gathers into chromosomes and the nuclear envelope, which is the membrane that encloses the nucleus, disintegrates during prophase. DNA synthesis or replication takes place during the S phase of a cell cycle, which happens during interphase and comes before mitosis or meiosis. Before a cell starts mitosis or meiosis.

In 1973, biologist Theodosius Dobzhansky wrote an essay titled "Nothing in Biology Makes Sense Except in the Light of
Evolution." Why is evolution so important for understanding biology? Explain your answer in 1-2 sentences. (2 points)
Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.
What is the purpose of the theory of evolution?The Theory of Evolution states that it is the environment, through natural selection, that determines the importance of the individual's characteristic or its variations, and the organisms best adapted to this environment have a greater chance of survival, leaving a greater number of descendants.
With this information, we can conclude that Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.

A scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans.
After doing DNA analysis, they determine that the organisms share the following percentages of DNA:
Organism A and humans share 85% of their DNA.
Organism B and humans share 80% of their DNA.
Organism C and humans share 90% of their DNA,
Based on this information, which order should they go on the cladogram (from least related to most related)?
(1 point)
O A, B, C, humans
OB, A, C, humans
o C, B, A, humans
OC, A, B, humans
B, A, C, Humans is the correct answer
Heyo! ;D
So, just to give you a heads up, these do change and sometimes vary for some, however please make sure before you look into these. Thanks! Just pre-warning!
1. The two organisms that are the most closely related would be:
~A and C~2. Based on the information of percentages of DNA, the order they should go on the cladogram (from least related to most related) would be:
~B, A, C, humans~3. The evidence that would support the relationships shown on the graph between amphibians, reptiles, birds, and mammals would be:
~Mammals have more genes in common with birds than with amphibians.~4. The piece of evidence, if true, that would most likely weaken the hypothesis that humans and chimpanzees have a common ancestor to gorillas would be:
~The cells of the eye on embryos of gorillas and humans follow a similar pattern of development while chimpanzee embryos are different.~5. The similarity of the structures of the forelimbs of bats and humans are known as:
~homologies~because they result from species evolving:
~from the same common ancestor~6. The suggestion above discussing the fact "all vertebrate embryos have a tail and gill slits at some point during embryonic development" helps to suggest that:
~These species share a common ancestor.~7. The conclusion that can be made based on the statement "Fossil A is found closer to the surface compared to Fossil B." would be:
~Fossil B is most likely older than Fossil A.~8. The statement that could be used to explain the similarity of the developmental process of vertebrate embryos would be:
~All vertebrates develop a backbone that protects the spinal cord.~9. The term for the remains, imprints, or traces of living things from a previous geological age would be:
~Fossils~10. The reason some mutations, or changes in the sequence of DNA, don't have any effect on the characteristics of the organisms would be:
~The mutated sequence still codes for the same amino acid.~11. What is typically studies when analyzing not-yet-born (or unhatched) animals is:
~embryological development.12. What scientists can analyze to get a better understanding of how plants and animals evolved from a common ancestor is:
~DNA molecules~13-16. The rest of the questions are written responses, 13-15 being short answers and the last being a single 3-5 sentence response. But no fear! These are rather easy ones to do by yourself. Or, if you really need help, I found a lot of really helpful responses on here. Anyways, good luck!
Indicate whether the statements below are TRUE or FALSE.
1. You work with two sugars. Glucose (MW = 180 Da) and Sucrose (MW= 342 Da). You make various solutions of each sugar separately and compare them. When you compare two 1-liter solutions containing these sugars at a 10mM concentration, there are more molecules of sucrose in 1 liter because its MW is higher than that of glucose.
2. When you compare two solutions at the same percentage concentration (e.g. 1%), the molarity (= concentration in mole/liter) is higher for glucose because the molecular weight of glucose is lower.
3. When you have 1 liter of a solution containing 90g of glucose, you must use 171g of sucrose to make a 1-liter sucrose solution with the same molar concentration.

Null mutations in ________ genes would be expected to result in the failure to establish the anterior-posterior poles of an embryo.
a. gap.
b. pair-rule.
c. coordinate.
d. homeotic.
Answer: c. coordinate.
Explanation:
Coordinate genes are those genes which are responsible for the development of major coordinate axes in the embryo. These axis include the anterior posterior axis and dorsal and ventral axis. These genes are responsible for the development of front, rear, top and bottom portions of the embryo. A null mutation restricts the transcription and translation processes in a gene thus when the RNA is not produced then no functional protein is expected. If the null mutations occur in the coordinate genes than it will effect the embryonic development. This will interfere in the formation of anterior and posterior poles of the embryo.
Null mutations in coordinate genes would be expected to result in the failure to establish the anterior-posterior poles of an embryo (Option c).
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.A null mutation is a type of mutation that prevents RNA transcription from a given gene or protein translation.In consequence, a null mutation is a loss of function mutation that leads to the faulty production of the associated gene product (i.e., the protein).In conclusion, null mutations in coordinate genes would be expected to result in the failure to establish the anterior-posterior poles of an embryo (Option c).

Describe how the lactic acid produced in muscle cells enters the blood
Answer:
Explanation:
Fast-twitch muscle also uses glycolysis to produce energy, but it skips harvesting energy from pyruvate, a process that takes oxygen. Instead, pyruvate gets converted into a waste product, lactic acid, and released into the bloodstream
Answer: Lactic acid is produced in your muscles when you perform strenuous exercise. It’s produced mainly in muscle cells and red blood cells when the body breaks down carbohydrates for energy when oxygen levels are low. These levels decreases during intense exercise or when a person has an infection or disease.

Imagine that fully functioning kidneys have been successfully created through bioengineering. What data analysis would measure the effectiveness of bioengineered organs in improving access to organ transplants among diverse groups of people, and what evidence would be needed to demonstrate that bioengineered organs have improved access
Answer:
The correct data analysis and evidence is:
Analysis: Compare the percentage of different ethnic groups who receive kidney transplants before and after bioengineered kidneys are available.
Evidence: A greater percentage of African Americans, Asians, and Pacific Islanders, and Hispanic/Latinos receive transplants after bioengineered kidneys are available compared to before
Explanation:
Bioengineered organs may be used to repair organs that have been destroyed. If the bioengineered organs are identical to the initial ones, transplantation rejection may be reduced.
So, to assess the effectiveness of organ donation adoption in people of various ethnicities, we should compare the percentage of people of various ethnicities receiving organ transplants before and after bioengineered organs became viable, and look for signs of a higher percentage of people of various ethnicities receiving organ transplantation after bioengineered organs became available.
