Answer:
The answer is D, Can planting cover crops reduce erosion?
Explanation:
Explanation:
RNA polymerase II is inhibited by certain drugs and toxins. One well-known inhibitor of RNA polymerase II is a toxin called α-amanitin, which is found in some species of poisonous mushrooms, such as the death cap mushroom (Amanita phalloides).
α-Amanitin functions by binding to RNA polymerase II and preventing it from transcribing messenger RNA (mRNA). This inhibition of mRNA synthesis disrupts the process of protein production in eukaryotic cells, which can ultimately lead to cell death and various toxic effects in the affected organism.
It's important to note that inhibition of RNA polymerase II is highly toxic and can be fatal if ingested. Poisoning from mushrooms containing α-amanitin can result in severe liver and kidney damage. If there is a suspicion of mushroom poisoning, immediate medical attention is crucial.

b.oxygen, nitrogen, and sulfur.
c.hydrogen, oxygen, and nitrogen.
d.carbon dioxide, hydrogen, and phosphorus.
The right answer is A.carbon, hydrogen, and oxygen.
Carbohydrates are composed of 3 types of atoms: carbon (C), oxygen (O) and hydrogen (H). Their general formula is written: Cn (H2O) n, (hence the name carbohydrate). There are 2 major carbohydrate families: Simple carbohydrates (monosaccharides and polysaccharides) and complex carbohydrates.
Several foods of different origin contain carbohydrates: sugar, fruits, milk, bread, dough, rice, pulses ... Their role is to bring energy to each of our cells.
The elements found in carbohydrates are carbon, hydrogen, and oxygen. No matter if it's a simple sugar like glucose or a complex carbohydrate like cellulose, these elements remain consistent. Thus, the answer is (a) carbon, hydrogen, and oxygen.
The carbohydrates you're referring to contain three common elements: carbon, hydrogen, and oxygen. These three elements are consistent across all forms of carbohydrates, regardless whether it's a simple sugar (monosaccharide) like glucose or a complex carbohydrate (polysaccharide) like cellulose.
For example, glucose (C6H12O6) is made up of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. The ratio of hydrogen atoms to oxygen atoms in carbohydrates always approximates 2:1, similar to water. This is a key characteristic that defines carbohydrates.
So, the answer to your question is option (a) carbon, hydrogen, and oxygen.

b. vital organs that are functional only in alternate generations of a lineage
c. redundant organs present in an organism, which have been functional in the organism’s ancestors
d. redundant organs present in an organism, which will be functional in the succeeding generations of the lineage
Answer:
The correct answer is c. redundant organs present in an organism, which have been functional in the organism’s ancestors.
Vestigial organ are those which are retained in the evolution however lost their original functions due to change living habits or surroundings of the organisms.
They serve as the evidence of evolution and help in evolutionary studies.
For example, vermiform appendix, nictating membrane of eye, ear muscle etc are vestigial organs found in humans.
A mutated sperm cell will always be destroyed during meiosis before it leaves the testes, while skin mutations remain within the skin.
There is little chance that a sperm mutation will affect the testes, while skin mutations almost always develop into cancer.
The mutation in the sperm cell could be passed on to offspring, while the skin cell mutation could only affect the individual.
Answer:
The mutation in the sperm cell could be passed on to offspring, while the skin cell mutation could only affect the individual.
Explanation:
There are two types of mutations: germline mutations (which affect the ovules or sperm), and somatic mutations (they occur in certain cells, for example, in the skin). Each one is defined below:
-Germinal mutations are inherited from a parent and are present throughout life in each cell of the body. These mutations are located in the ovules or sperm of the parents and are transmitted as inherited mutations.
-Somatic mutations can occur at any given time and only in certain cells. These mutations may be due to, for example, environmental factors, such as radiation from the sun, in this case affecting skin cells. These types of acquired mutations are not transmitted to the next generation.
