This question is unfortunately incomplete. A <span>neurotoxin that blocks voltage-gated na+ channels will have all of the effects listed: there will be impairment of action potentials and neurotransmitter release, and in sufficient quantities, the toxin will prove fatal to the organism.</span>
Answer:
0
Explanation:
Because if oyu say 80 plus 100000000 it equals 0
Rats account for a decent amount of biomass globally. They are intermediate predators, eating a lot but also being eaten. If they went extinct, they would stop eating many insects and seeds / fruits -- the former would gain significantly in population, and the latter would lose some of their pollination. Both factors would harm the viability of at least some species of plants, by adding to plant eaters (insects) and reducing plant reproduction. Rats' predators would also suffer if they went extinct. The primary predators are birds of prey, such as hawks and owls. However, other animals such as skunks, foxes, weasels, coyotes, and even wolves eat rats. For predators in marginal environments, the loss of such a food source could drive them out of a habitat area.
Answer:
Humans have about a thousand genes similar to those of bacteria ,because the genes are so vital that thier DNA structure has remained much the same over millions of years of decent from a common ancestor.
Explanation:
Proteins -<span> A molecule composed of polymers of amino acids joined together by peptide bonds. It can be distinguished from fats and carbohydrates by containing nitrogen. Other components include carbon, hydrogen, oxygen, sulphur, and sometimes phosphorus.</span>
amino acids -Amino acids<span> are the building blocks of all </span>biological<span> proteins.</span>Amino acids<span> link together via peptide bonds in a particular order as defined by genes. Genes are translated by RNA to</span>amino acid<span> chains; the length and order of the </span>amino acid<span>chain then dictates the three-dimensional structure of a polypeptide or protein.
