What is the goal/function of the ETC? (select all that apply)

Biology
1 answer:
joja [24]3 years ago

Answer:

The ultimate goal of the ETC is to produce the high-energy molecule adenosine triphosphate (ATP) to catalyze biochemical reactions. The precursors of ATP, adenosine diphosphate (ADP) and inorganic phosphate (Pi) are readily imported into the mitochondrial matrix.

One way the body fights invaders is by increasing the body temperature, or running a fever. Give a brief explanation as to why t
eduard

Some bacteria are not able to function properly and replicate at the fever-high temperatures hence this reduces their infection rates in the body. More research has also shown that the temporal increase in body temperature, during the fever, increases the  activity of the cytotoxic T-cells that are significant in fighting infection.

- For plants and other organisms to develop differences among their respective species the alleles of their genes must contain
andre [41]

Explanation:

Mutations increase variation within a population.

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

  • somatic: these only occur within certain cells, and arise from environmental factors such as UV light
  • hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Further Explanation:

During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

Why rhizoids not called roots?
garik1379 [7]
Most plants have roots, but there are some
exceptions. The exceptions are bryophytes
and the groups of green algae that are
classified as plants. Bryophytes have rootlike
structures called rhizoids for absorbing
water, but because rhizoids lack vascular
tissue they are not considered roots.
