The changes that occur during puberty are mostly a result of changes in hormone levels in the body.
<h3>Puberty</h3>
The transition from a child to an adult is caused by changes in the level of some hormones in the body.
In females, there is an increase in follicle-stimulating hormones as well as luteinizing hormones, leading to an increase in the production of progesterone.
In males, there is an increase in the production of testosterone hormone among many other hormones.
Both progesterone and testosterone are responsible for the development of physical features in females and males respectively.

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.

The answer is; C
Meisos involve halving the genetic material of a cell to form garments. The gametes of two parents fuse to form a zygote that6 returns the genetic material to normal ploidy so it can develop into offspring. The fusion of two gametes is called fertilization.
The answer is D! birds have to migrate for winter to find an abundance of food! they learned this over time making it a learned adaptation
