I believe the answer is echinodermataechinodermata and Chordata have a very similar embryonic development; tirhe first opening (the blastopore) becomes the anus, while in protostomes it becomes the mouth and several similarties in the formation of skeleton.It is predicted that Echinodermata and Chordata evolved from the same ancestor
They have all been formed by sandblasting
This is false
This selection and variation happens more gradually. It is hard to notice over a short period of time. The change is slow, constant and consistent. In punctuated equilibrium, the changes come in spurts. There are periods wherein a huge change occurs and there are also periods with very little change. The mutation is at random. Genetic drift is the change in the frequency of a gene variant due to a random sampling of organisms.
The nuclear membrane, the endoplasmic reticulum, the Golgi apparatus, lysosomes, vesicles, endosomes, and plasma
If a heterozygous male with the genotype Ww is mated with a homozygous recessive female with the genotype ww, then the probability of heterozygous offspring is 0.5 or 50%. The offspring are Ww, Ww, ww, and ww.
<h3>What is Genotype?</h3>
A genotype may be defined as the ultimate combination of the alleles of those genes which are selected for specific studies.
If a heterozygous male with the genotype Ww is mated with a homozygous dominant female with the genotype WW, then the probability of heterozygous offspring is 0.5 or 50%. The offspring are WW, WW, Ww, and Ww.
Therefore, it is well described above.
