elect all statements that accurately describe the structures or functions of mitochondria. Mitochondria are the sites of aerobic metabolism. Mitochondria have a permeable inner membrane and an impermeable outer membrane. Mitochondria regulate apoptosis. Mitochondrial DNA is packaged with histones. The configuration of mitochondria does not change. Mitochondria are included in the endomembrane system.
Answer:
The correct statements are -
Mitochondria are the sites of aerobic metabolism
Mitochondria regulate apoptosis.
Explanation:
Mitochondria is one of the eukaryotic cell organelles that are double membrane and plays important role in the different function of the cell. The main and major function of the mitochondria is aerobic metabolism that includes aerobic respiration where glucose converts into carbon dioxide and water with releases a high amount of energy in the form of ATP.
These also plays important role in programmed cell death or apoptosis it activates apoptosis by releasing protein by the inner and outer membrane. The inner membrane of mitochondria is impermeable and allows through transporters and outer membrane non-specifically permeable to low molecular substances. Mitochondrial DNA lacks histone protein and TFAM, an HMG-like protein involved in the process.

Which of the following is a critical factor driving evolution?
Environmental conditions
Health in comparison to similar organisms
Ability to acquire food
Strength in comparison to similar organisms
All of these are equally important
all of these are equally important, what if there is an option for natural selection, natural selection would be the most important but for this it's all these are equally important.
The critical factor driving evolution is strength in comparison to similar organisms.
According to Charles Darwin, Organisms that are better able to survive in their environment live long enough to reproduce and pass on these favorable traits to their offspring leading to the perpetuation of these organisms and gradual demise of other individuals of the same species who lack these favorable traits.
This is the origin of the cliché, "survival of the fittest". Hence organisms that lack certain strengths possessed by other organisms are gradually replaced by other individuals having such strengths.

Explanation:
You are studying a plant whose seeds persist in the soil for a long time, normally only germinating when the seeds are brought to the surface in full sun by a disturbance such as a tree fall. However, in one of your experimental lineages you find that many seeds germinate when the surface is in full sun even if the seeds are buried too deep to grow to the surface before exhausting their reserves. You suspect that this lineage has a mutation that inhibits:
Answer:
The conversion of Pfr to Pr.
Explanation:
If the seeds germinates properly when the surface is in full sun and persist to germinate when buried deep into the soil, this shows that this lineage of seeds has a mutation that inhibits the conversion of Pfr to Pr
Which of the following are functions of the reproductive organs in animals?
I. Produce sperm
II. Support the body
III. Protect the internal organs
IV. Make the eggs
I and II
II and IV
I and IV
II and III
Answer:
c
Explanation:
I and IV are the functions of the reproductive organs in animals.
What are Reproductive organs?
The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.
The fertilized egg is then transferred to your uterus, where the lining has expanded due to the regular hormones produced during your menstrual cycle (also called your reproductive cycle).
The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur. The female reproductive system also creates sex hormones that keep your menstrual cycle regular.
Therefore, I and IV are the functions of the reproductive organs in animals.

g The primary digestive enzyme released by the stomach, as well as many of the digestive enzymes created and released by the pancreas, are initially released in their inactive form and must be activated after the fact. For one, explain how this activation occurs (and how it differs between the enzymes from these two organs), and for another, explain why this paradigm of releasing inactive enzymes is so important, physiologically.
Answer: The release of inactive form of enzyme is important because when the enzyme will active on its release it can digest the organs and glands from where it had been released to support the function of the enzyme only when it is required to be released and promote its functioning at the target site the enzyme is required to be released only in an inactive state.
Explanation:
Pepsin is a an enzyme secreted by the stomach cells in the inactive form that is called as pepsinogen. The function of the pepsinogen is to digest protein in the food. The activation of pepsin requires an acidic pH maintained by the hydrochloric acid in the gastric secretion of stomach. The pancreatic cells secrete enzyme trypsinogen which is activated into trypsin when it enters into the duodenum of the small intestine by the enzyme enteropeptidase.

What do echinoid, snail, and shark tooth fossils have in common?
Answer: All have calcium made structures which restricts their degradation and decomposition.
Explanation:
Echinoids and snails have exoskeleton which is hard and made up of calcium carbonate which is the least degradable material even after death of the organisms and remains as traces and remains in the fossils. Also the shark tooth is made of dentin which is a hard calcified tissue which does not decompose very easily. It is denser and harder then the bones. It is surrounded by the enamel shell. The dentin and enamel prevent the degradation and decomposition of the shark tooth for long hence, it gets available as fossil.
