1. Why is most food digested?
A. Digestive enzymes require a variety of substrates.
B. It ensures that the diet is balanced.
C. Most ingested food molecules are large.
D. To prevent disorders of the intestine.
1. Why is most food digested?
C. Most ingested food molecules are large.
Food is digested to break down big particles of food into smaller ones so that the absorption process takes place more efficiently.
Answer:
C
Explanation:
As food molecules are very large during intake, they cannot be absorbed by the small intestine as macromolecules. They need to broken down into smaller molecules for absorption to take place.

A.They are closely related but different species.
B.They are the same species.
C. One organism evolved from the other.
D. They are not related at all.
The two DNA sequences of organisms represent that they are closely related but different species.
What do you mean by Species?Species may be characterized as a group of organisms that can reproduce naturally with one another and produce fertile offspring.
DNA fingerprinting is a technology that reveals the similarity between the DNA sequences of two or more organisms of the same or different species.
Both the sequence are very similar to one another, only a few bases are altered which signifies that they are closely related but belongs to different species.
Therefore, the two DNA sequences of organisms represent that they are closely related but different species.

What is ecosystem homeostasis?Ecosystem homeostasis refers to the state of ecological equilibrium in a particular ecosystem.
The delicate balance between producers and consumers is fundamental to maintaining the ecosystem's health.
Producers (e.g., plants), primary consumers (e.g. herbivores), and secondary consumers (e.g., carnivores) are single players that need to interact to achieve the overall health of the ecosystem.
Loss of biodiversity due either to the lack of producers or consumers can alter the homeostasis of the ecosystem.

The gradual process during which glucose is broken down to release energy
Answer:
If the energy in glucose was released at once, most of the energy would be lost as light and heat. The light and heat could harm or even destroy the cell. The gradual process of cellular respiration allows the cell to control the release of energy into packages of ATP that can be used efficiently for cell activities.

What is the effect of climate change on polar regions?Climate change causes melting of ice caps in colder regions where polar bears live. This change has made it harder for polar bears to successfully hunt seals. This situation will lead to extinction of polar bears in this location because they can't get their food which leads to their death.
So we can conclude that extinction occurs due to the climate change in the polar regions of the earth.

Explain two ways in which the alveoli are adapted to increase the efficiency of gas exchange
Answer:
Adaptations of the alveoli:
Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through. Extensive blood supply - ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.
What changes occur in the gastric chyme(mixture of food inside stomach) when it passes to duodenum?

Although both humans and bacteria have ribosomes, streptomycin—which blocks ribosome function—does not harm a human who ingests it. Why?.
Streptomycin does not harm a human who ingests it because bacteria have different ribosomal units.
What is a ribosome?Ribosomes are organelles used by cells to synthesize proteins, it is for that reason that they are called protein factories.
Ribosomal units are different in eukaryotic cells (e.g. human cells) compared to prokaryotic cells and they do not bind to streptomycin in eukaryotes.
In conclusion, Streptomycin does not harm a human who ingests it because bacteria have different ribosomal units.

What is the net result of one glucose molecule going through the krebs cycle.
Answer:
Recall that glycolysis, stage I of cellular respiration, produces two molecules of pyruvate. These molecules enter the matrix of a mitochondrion, where they start the Krebs cycle.
Two molecules of pyruvate are produced during the first stage of cellular respiration, glycolysis. These substances enter a mitochondrion's matrix, where they initiate the Krebs cycle.
Thus, A little quantity of ATP (adenosine triphosphate) is produced by the Krebs cycle through substrate-level phosphorylation. Two ATP molecules are directly created in the Krebs cycle for every glucose molecule.
Electron transport chain (ETC): The Krebs cycle also generates high-energy electron carriers called NADH (nicotinamide adenine dinucleotide) and (flavin adenine dinucleotide), which transport the electrons to the ETC for additional ATP generation.
Carbon dioxide is generated as a waste product during the Krebs cycle's breakdown of glucose. Six CO2 molecules are produced overall for every molecule of glucose.
Thus, Two molecules of pyruvate are produced during the first stage of cellular respiration, glycolysis. These substances enter a mitochondrion's matrix, where they initiate the Krebs cycle.
