Answer:

The all-or-none law is a principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fiber will fire.

Between a Black father bear (genotype BB) and a Brown mother bear (genotype bb), they had several baby bears.Black fur allele (B
Karolina [17]

Answer:

100% or 1

Explanation:

This question involves a gene coding for fur color in bears. According to the question, black fur allele (B) is dominant over the brown fur allele (b). This means that a bear heterozygous for fur color (Bb) will be phenotypically black.

In this question, a black father bear (genotype BB) and a brown mother bear (genotype bb) were crossed, the baby bears will all have a genotype Bb (see punnet square in the attached image). Since all the offsprings of this cross have genotype Bb, this means that 100% will have black fur.

True or false: Theoretically, it is possible (but very difficult) for a population to not evolve for a while.
Debora [2.8K]

It is true that it is possible for a population to not evolve for a while.

There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.

There are 5 Hardy-Weinberg assumptions:

  • no mutation
  • random mating
  • no gene flow
  • infinite population size
  • and no selection (natural nor forced).

You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.

For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.

Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.
