What happens to the cell’s genetic information during the cell cycle?
Answer:I think During most of a cell's life cycle, DNA, along with proteins, is a mass of loose strands called chromatin (KROH-muh-tin). Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.During interphase, the cell obtains nutrients, and duplicates (copies) its chromatids (genetic material). The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA. hope this helps have a nice night ❤️❤️❤️

Many science fiction stories deal with the possibility of being able to “design” our children by choosing the specific physical and personality traits we would like them to have. How do you think a scientist would go about the process of “designing” your own child. Do you think this is a good idea? Why or why not? Use specific reasons and examples to support your position.

What is the main challenge of moving towards only using alternative energy sources such as wind, water, or solar
Answer:
It's not too complicated
Explanation:
There are many factors to consider because there's different decision/energy complexities to factor. Your farming-role (energy requirements) determines the energy requirements.
If you are an electrical farmer, for example, you might require intricate measurements of energy -- like sunar rays (solar ray force). This is one subverse to observent, before making a stupper decision.
Meiosis causes the offspring of organisms that have sexually reproduced to be genetically diverse this is because meiosis is produces.

The answer is Option 3, -genetically unique cells that will increase variation in a population.-
Which of these groups has the most organisms?
A. Class
B. Order
C. Phylum
D. Genus
The group that has the most organisms is the phylum that is present in Option C as the In the taxonomic hierarchy, a phylum is a level above a class, and it contains multiple classes.
What is a phylum?A taxonomic hierarchy is a system used to classify and organize living organisms based on their shared characteristics and evolutionary relationships, and the hierarchy is composed of different levels or ranks, and at the top is the domain, which represents the broadest and most inclusive category, while below the domain are the kingdoms, followed by phyla, classes, orders, families, etc. Phyla are one of the broader categories in the hierarchy, and they include groups of organisms with a common ancestor and shared characteristics that distinguish them from other groups, and an examples of phyla include the chordata.
Hence, the group that has the most organisms is the phylum that is present in Option C.

How is the production of NADPH useful for the process of photosynthesis?
The Calvin cycle is maintained and powered by the NADPH generated during the light-dependent stage of photosynthesis.
What is the role of NADPH is the photosynthesis?From the thylakoid to the stroma, NADPH moves. It is a high-energy electron carrier that transports both high-energy electrons and the hydrogen needed to make sugar.
NADPH will go to the Calvin cycle, where its electrons will be used to convert carbon dioxide into carbohydrates. ATP is the other component required by the Calvin cycle, and the light reactions also supply this.
NADPH is created during photosynthesis by using light energy in the chloroplasts' electron transport chain.
The Calvin cycle and subsequent processes that result in the production of carbohydrates can subsequently utilize it as a form of energy currency.
Therefore, the production of NADPH useful for the process of photosynthesis.

How would the way I dress be impacted if photosynthesis stopped tomorrow?
write half a page for full credit
thank you you're a lifesaver
Answer:
i dont want to do so much writing but i guess i will help
Explanation:
If photosynthesis came to an abrupt end, most plants would die within short order. Although they could hold out for a few days -- or in some cases, a few weeks -- how long they lived would largely be a factor of how much sugar they had stored within their cells. Large trees, for example, may be able to soldier on for several years — perhaps even a few decades — because of their energy stores and the slow rate of use. However, the majority of plants would meet a withering end, and so would the animals that rely on them for nourishment. With all the herbivores dead, the omnivores and carnivores would soon follow. Although these meat-eaters could feed on all the carcasses strewn about, that supply wouldn't last more than a few days. Then the animals that temporarily relied on them for sustenance would die.

What are the new cells called and how do they compare with each other?
Answer:
The original cell is called the mother cell and the two new cells are called daughter cells.
Explanation:
The mitotic (M) phase and cytokinesis (C phase) together are called cell division, the division of the parent cell (original) into two daughter cells (new cells), each with the same genetic information (chromosomes) as the parent cell. Mitosis does NOT occur in prokaryotic cells that do NOT have a nucleus. (tesd. net)
The nucleus divides during mitosis, while the cytoplasm divides during cytokinesis. The two new cells are referred to as daughter cells.
What is daughter cells?Diploid cells are the daughter cells of mitosis. Diploid cells have two complete chromosome sets. Mitosis creates no genetic diversity in normal healthy cells because the daughter cells have exact copies of their parent cell's DNA. Either of the two cells formed when a cell divides through mitosis. Because they have the same number and type of chromosomes as the parent cell, daughter cells are genetically identical. Daughter cells are formed by the division of a single parent cell. They are produced by the mitotic and meiotic division processes. Cell division is the reproductive mechanism that allows living organisms to grow, develop, and reproduce.To learn more about daughter cells, refer to:

What role do cell membranes and protocells play in the "RNA" world?
Answer:
reibosome
Explanation:
Reibosome is a large molecular complex that assmebles proteins.
Role of Cell membranes and Protocells:
Messenger RNA (mRNA) carries the protein blueprint from a cell's DNA to its ribosomes, which are the "machines" that drive protein synthesis. Transfer RNA (tRNA) then carries the appropriate amino acids into the ribosome for inclusion in the new protein.Protocells are thought to have facilitated the reproduction of RNA and therefore the exchange of genetic information at a time before the advent of DNA and proteins.Learn more:
