In the Calvin cycle, which of the following best describes the sources of the elements that combine to make sugar?
A. The carbon and oxygen from carbon dioxide combines with the hydrogen and oxygen in water taken in during the Calvin cycle to make sugar.
B. The carbon, oxygen, and hydrogen from stored sugars are reprocessed during photosynthesis to make new sugar molecules.
C. The carbon and oxygen from carbon dioxide combine with the hydrogen taken from water during the light-dependent reactions to make sugars.
D. The carbon that is taken from carbon dioxide during the light-dependent reactions combines with the hydrogen and oxygen in water to make sugars.
In the Calvin cycle, the carbon and oxygen from carbon dioxide combine with the hydrogen taken from water during light-dependent reactions to make sugars. The correct option is C.
What is a Calvin cycle?The Calvin cycle, also known as the C3 cycle, is a series of chemical processes used by plants to convert carbon dioxide and other chemicals into glucose.
RuBP is a straightforward five-carbon molecule that receives carbon from the atmosphere through the Calvin cycle processes. These processes utilize the NADPH and ATP created during the light reactions as a source of chemical energy. Glucose is the Calvin cycle's end result.
Therefore, the correct option is C. The carbon and oxygen from carbon dioxide combine with the hydrogen taken from water during the light-dependent reactions to make sugars.

What is complementary base pairing? Explain why complementary base pairing is necessary to maintain the double helix shape of the DNA molecule.
Answer:
A complimentary base pairing is how adenine can only bond with thymine and how guanine and cytosine through hydrogen bonding. It is necessary to maintain the double helix shape. Because it is opposite, that is why the DNA is that shape. It is anti parallel due to the Complementary base pairing.
Adenine can only bond with thymine and guanine with cytosine via hydrogen bonding. It's important to keep the double helix shape. Complementary base pairing causes antiparallelism.
Why complementary base pairing is necessary?Base pairs linked to a sugar-phosphate backbone form the double helix structure of DNA.
DNA is composed of four nitrogenous bases: thymine, adenine, guanine, and cytosine. Guanine and cytosine are linked by three hydrogen bonds, while adenine and thymine are linked by just two. The term for this is complimentary base pairing.
Complementary base pairing is critical for the formation of the helical helix of DNA because it permits the base pairs to be organized in the most energetically favorable manner. It is also essential for replication since it permits semiconservative replication.

Grizzly bears are top carnivores in some North American ecosystems. What do you think might happen to a community of organisms if grizzly bears suddenly became extinct?
Answer:
There would be an increase of the population of the prey that the Grizzly bears eat
Explanation:
what would happen if a new predator was introduced into the ecosystem that only ate mice ? Would the mouse population be lowered ?What else would happen because of this
Answer:
The mice population would be lowered, and that predator could be a prey to other predators in that environment.
Explanation:
The introduction of new predator has both positive as well as negative effects on the ecosystem and environment.
What happen when the predator in introduced in an ecosystem?If a new predator was introduced into the ecosystem that only ate mice so this results in the reduction of population of mice which leads to the disturbance of the ecosystem.
So we can conclude that introduction of new predator has both positive as well as negative effects on the ecosystem and environment.

Since plastic doesn't biodegrade in the oceans, what does the future hold? What can be done to make the future better?
Answer:
We need to take out the plastic and recycle
Explanation:
The future is scary if we don't act upon our actions. There are many people trying to restore the oceans and providing options for the average person. Some time ago I saw an advertisement for a search engine that if you use it they will take away plastic from the ocean. It was called OceanHero but there are others that do the same thing, such as: Okeano..etc. But another way is to prevent plastic from going into the ocean in the first place by limiting use of single use plastics and setting nets on pipes that lead to rivers to catch stray micro plastics. Another good idea is to ensure that we are not littering and following recycling rules. If we fail to save what we have left, ocean animals may only exist as skeletons and images in a museum.
Hope this Helps!

The p53 protein is a transcription factor that regulates a cell's progression through the cell cycle after DNA is damaged by ultraviolet ( UV ) radiation. The p53 pathway is shown in Figure 1.
Please answer this question! I will give brainliest!
Please note: p53 regulating image is for the entire problem, whereas part C image is only for part C.
(a) A skin cell completes one round of the cell cycle. Describe the products.
(b) Based on Figure 1, explain how p53 regulates the cell cycle in the presence of damaged DNA .
(c) Draw an X on the template in the space provided for your response to indicate the phase during which the replication of damaged DNA would occur.
(d) Based on Figure 1, explain how a mutation to p53 may lead to an increased risk of cancer.
Answer:
(a) Since skin cells undergo the process of mitosis, the product of one cell cycle is 2 identical daughter cells.
(b) The levels of p53 protein in the cell will rise in response to DNA damage. This will stop the cycle at one point to give time to the repair machinery to regain stability. As can be seen in the figure, CDK inhibitors have been produced which are responsible for halting the cell cycle.
(c) The S phase (synthesis phase) is when replication of damaged DNA would occur.
(d) p53 responds in one of 3 ways to an event of DNA damage: arresting the cell-cycle, apoptosis (programmed cell death), or repairing the DNA. If there has been a mutation in p53, neither of the three way would take place to prevent more copies of damaged DNA being made. A mutated p53 protein would no longer be able to suppress tumors.
Hope that answers the question, have a great day!
The cell cycle is the process in which a cell undergoes four phases of division to give rise to daughter cells.
(a) The skin cell is a type of somatic cell, which undergoes mitotic division. The products of the cell cycle will be two identical daughter cells.
(b) p53 is a transcription factor, which will halt the replication if any error occurs. CDK inhibitors are produced in the cycle, which regains stability and activates the repair mechanism.
(c) The synthesis phase or S phase of the cell cycle is the site where replication of the DNA occurs. It takes place after the G1 phase.
(d) p53 transcription factor can arrest the cell cycle, cause apoptosis, and repair the cell damage. The mutation in the p53 gene can work in any fashion to prevent more damaged copies of the DNA. The mutation in p53 will lead to tumors.

How are the blunt and sharp pipettes
used in the cloning process?
(please answer in simple words i don't even understand the question)
Answer:
During the process of the type of cloning known as Somatic Cell Nuclear Transfer (SCNT), once the nucleus is removed from the egg cell, blunt and sharp pipette both are used. The purpose of the blunt pipette is to hold the egg cell in position whereas the sharp pipette penetrates the cell to take the nucleus out by sucking it - a process known as "enucleation". This nucleus is discarded. Rather, this nucleus is replaced by a nucleus taken out from a somatic cell (same way as described before) of the same organism.
