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 role do cell membranes and protocells play in the "RNA" world?
Answers
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:

What happens to the cell’s genetic information during the cell cycle?
Answers
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 ❤️❤️❤️

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 do I write a essay using the digestive urinary and excretory system to maintain homeostasis.
Answers
The digestive system takes the food we eat, pulls out the energy we need to move and live, and passes on the waste to be excreted. If it didn’t excrete the waste, toxins would build up in the body.
The urinary system maintains homeostasis by filtering toxins out of the blood, and deciding how much water should be retained or wasted, based on our blood’s chemistry.
Another part of the excretory system is our skin. We sweat out toxins from exercise.

Answer:
Bird A survives and both b and c die
Explanation:
Hi! hopes this help :)
Three bird species share a habitat Bird A eats insects and plants seeds. Bird B drinks flower nectar. Bird C eats plant seeds. Drought occurs in their habitat, and that season's plants are wiped out entirely under this condition only Bird A survives, both birds B and C die due to the condition of resource scarcity.
What is resource scarcity?In the ecology, resource scarcity was mainly represented by the two factors that are food and water which are primary resources for survival if anyone one resource is not available for the bird species it will affect its survival.
Therefore, due to the resource scarcity only Bird A survives, both birds B and C die.

What are the new cells called and how do they compare with each other?
Answers
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:

How is the production of NADPH useful for the process of photosynthesis?
Answers
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.
