The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.
The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:
- Zygote: Fertilized ovum.
- Blastocyst: Cluster of cells that is the result of the zygote going through cell division.
- Embryo: Unborn human that is still developing, usually before the 8th week of gestation.
- Fetus: Unborn human in development after the 8th week of gestation.
Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

Answer:
If two heterozygous pea plants are crossed with yellow round seeds, the resulting progeny mostly show the dominant phenotype.
Explanation:
Plants with two different alleles of a gene are heterozygous. As all the heterozygous offspring are yellow, then the yellow allele must be dominant over the recessive green allele.

The trigonometric ratios are;
- Sin A = 0.78
- Cos A = 0.625
- Tan A = 1.25
<h3>What are the trigonometric ratio?</h3>
The trigonometric ratios are sine, cosine and tangent. Now we have the hypotenuse of the triangle. Figure 1 has been shown in the image attached to this answer.
c = √8^2 + 10^2
c = 12.8
sin A = 10/12.8 = 0.78
Cos A = 8/12.8 = 0.625
Tan A = 10/8 = 1.25
