Answer:
Gregor Mendel used "Cross Polination"of parents that have different traits to produce offsprings.True or false: Polygenic traits that are subject to environmental influences can control multifactorial traits.
True, Polygenic traits that are subject to environmental influences can control multifactorial traits.
What is Polygenic and Multifactorial trait?Multifactorial traits are traits influenced by many factors, including genetic and environmental factors.Polygenic traits are traits that are controlled by many genes.The multifactorial trait may be continuous or discontinuous, but the polygenic trait is continuous.Multifactorial traits are polygenic traits that are strongly influenced by the environment.Many human disorders are multifactorial or polygenic diseases.Multifactorial and polygenic diseases are very complex to resolve.So, polygenic traits when influenced by the environment are called multifactorial traits.To learn more about Genes and Traits,

ATP will be utilized for transport the maximum rate of transport will occur. The protein carriers fall apart. the transport rate will increase the maximum rate of transport will occur
More about ATP:
ATP, sometimes referred to as adenosine triphosphate, is a chemical that transports energy inside of cells. It is produced as a byproduct of photophosphorylation, which adds a phosphate group to a molecule using light energy, cellular respiration, and fermentation. It serves as the primary energy currency of the cell. All forms of life utilise ATP.
What is facilitated diffusion?
The passive transport of molecules down the concentration gradient is known as facilitated diffusion. It is a selective process, meaning that only specific molecules and ions can pass through the membrane. But it blocks the passage of other molecules across the membrane.

A. Because energy is lost at every
level.
B. Because there are a set
number of niches in an
ecosystem that do not change.
C. Because there is not enough
room for so many organisms.
OD. None of these
Answer:
A. Because energy is lost at every level.
Explanation:
energy decreases as it travels from lower levels to upper levels--which is a logical observation you could make.
Think of it like this--if a fish eats a small organism, it will then spend some of the energy obtained from the organism swimming around--so when a larger fish eats our fish, the energy from the original organism will already be partially lost (from our fish swimming around).
This means that when this pattern continues over multiple levels, we keep losing energy--which limits the environment's capacity for organisms to survive.

And it prompted newts to produce more toxins, which are 10,000 times more deadly than cyanide. Seeds are involved in co-evolution games.

difference between bacteria and protists
Answer:
Bacteria and protists are unicellular organisms. The difference lies in the type of cells they have. Bacteria are placed in the kingdom Monera and have a prokaryotic cell, whereas protists are placed in the kingdom Protista and have a eukaryotic cell.
Answer:
Protists and bacteria differ mostly in their cellular structure. Prokaryotes are creatures that lack a nuclear membrane around their genetic material (DNA), such as bacteria. On the other hand, protists are eukaryotic (genetic material enclosed by a nuclear membrane).
Explanation:
Protists and bacteria are both often found to be single-celled creatures, yet they are extremely different from one another in almost every other way. Protists are creatures that belong to the Eucarya domain, like humans, and have internal compartments, a cytoskeleton, and many RNA polymerases in their cells. The size of eucaryal cells ranges from 10 to 100 microns (millionths of a meter). There are two types of bacteria: Eubacteria and Archaea, which are almost as unlike from one another as they are from Eucarya. Bacterial cells generally have a diameter of 0.5 to 5 microns. The simplest way to distinguish between them is based on size and whether or not they have nuclei; protists have one (or more), whereas bacteria don't. Finding their gene sequences—in particular, the sequences for ribosomal RNA, which is the most reliable method to categorize organisms—is a more accurate technique to separate them.
2. Why is there such a high rate of spontaneous mutation among the genes responsible for classic hemophilia, Duchenne muscular dystrophy, and achondroplasia
The genes responsible for classic hemophilia, Duchenne muscular dystrophy, and achondroplasia have a high rate of spontaneous mutation because these disorders are associated with sex-linked traits.
What is Spontaneous mutation?Spontaneous mutation may be defined as a type of mutation which carries in the body of an organism naturally without any interference from mutagens.
The genes of the above-mentioned disorders have a high rate of spontaneous mutations because they are unaffected by any external mutagens and are sex-linked traits that are inherited from parents to their offspring.

Beta adrenergic receptor-blocking drugs are often called beta-blockers. These drugs prevent the hormone epinephrine from binding to its G-protein-coupled receptor. In the pathway activated by epinephrine, the activated G-protein would normally activate adenylate cyclase. When the drug is in use, which step(s) is/are prevented
All the steps of GPCR signaling would be prevented in the presence of a beta-blocker drug.
What is Beta-blocker?Beta-blocker may be defined as a kind of medication that chokes the activity of substances, such as adrenaline, on nerve cells and provokes blood vessels to relax and dilate.
Adrenergic receptors choke the attachment of catecholamine that is epinephrine to the G-protein. G-protein activates adenylyl cyclase which in turn activates protein kinase A.
But when the beta-blocker drug is subjected to this pathway, it blocks the attachment of the hormone to their receptors, hence none of the pathway or steps would be carried forward. This is because signaling is not initiated.
Therefore, all the steps of GPCR signaling would be prevented in the presence of a beta-blocker drug.
