Answer: DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, the building blocks of DNA. These enzymes are essential for DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule.

The common ancestors of birds and mammals were very early (stem) reptiles, which almost certainly possessed 3-chambered hearts.
MatroZZZ [7]

The common ancestors of birds and mammals were very early (stem) reptiles, which almost certainly possessed 3-chambered hearts. Birds and mammals, however, are alike in having 4-chambered hearts. The 4 chambered hearts of birds and mammals are best described as homoplasies.

<h3>What about homoplasies?</h3>
  • It is more frequently a modified version of an inherited characteristic.
  • For instance, the scales that were already present in its reptilian parent led to the evolution of feathers in birds.
  • Similar to reptiles, mammals developed fur from their predecessors' scales.
  • The same set of data can typically yield more than one potential cladogram.
  • Different species of legged lizards developed into snakes and lizards with limbless bodies.
  • Natural selection does not affect a sizable number of mutations.
  • They came to the conclusion that reptiles, birds, and mammals all descended from the same ancient reptilian progenitor.

It is estimated that 5.9% of Americans have diabetes. Suppose a medical lab uses a test for diabetes that is 98% accurate for pe
vagabundo [1.1K]

Answer:

P (actually that randomly selected person has diabetes given as given by the lab) = 0.7725

Explanation:

A probability is a number, between 0 and 1, expressing the precise likelihood of an event happening.

Probability (person actually has diabetes) = 5.9%

P(lab test says that they have diabetes) = 0.0764

P (actually that randomly selected person has diabetes given as given by the lab) = 0.7725

In a diploid organism, there are ___ number of copies of most genes. In a population, there may be many different gene sequences
sineoko [7]

Answer:

In a diploid organism there are two copies of most genes.

The versions of the genes are called alleles.

Explanation:

Hello!

The genetic servants of a population are all variants of each of the genes present. These variables are possible thanks to the mutations that occur in the formation of the zygote (before or after fertilization).

When part of the DNA of an organism undergoes a point mutation (on one or a few nitrogenous bases) the body activates a series of responses to reverse it, however sometimes the mutation is maintained and can give rise to a change in a protein.

Sometimes and under certain circumstances (the change should not cause death or significant disadvantages in the body that is born) the mutation is maintained in the population giving rise to different alleles of the same gene.

In an organism there are two copies of each gene (genotype) but only one of them (phenotype) is expressed.

The allele of the gene that is expressed may depend on various factors but the dominant allele is usually expressed.
