In a population of peppered moths, the allele frequency of d shifts from 0.49 to 0.64 over successive generations. that means this population is not an equilibrium and is therefore evolving.

true

or

false

True

Explanation:

Allele frequency as the name says, basically indicates the relative frequency of a particular allele at a particular locus. This is mostly expressed in the form of percentage or fraction.

The formula for calculating it is:

          Allele frequency = no. of copies of allele at a particular location / total no. of all alleles for a gene in a population.

According to Hardy Weinberg theorem, if a population has constant allele frequency from one generation to another, it means that the population is evolving. So, as indicated in question that allele frequency is changing, it means that population is evolving.

Hope it helps!

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
