Once an egg has been fertilized, _____. (can be more than one answer)
a barrier to other sperm forms immediately
new genes are formed
cytoplasm is always exchanged
the zygote becomes haploid
Answer;
-zygote is formed
Once an egg has been fertilized zygote is formed.
Explanation;
-Fertilization is the fusion of two haploid gametes to produce a diploid zygote. Each haploid gamete in humans has 23 chromosomes, while the diploid zygote has 46.
-A fertilized egg is called a zygote until it divides into 16 cells, forming a ball-shaped structure called a morula. In humans, it takes about four days for a zygote to become a morula and another three days until the embryo attaches itself to the mother's uterine wall.
The answer is a zygote is formed.
In the process called fertilization, the egg cells or so called ovum will fuse with a sperm cell. The result of this fusion leads to the development of the zygote which will then develop to an embryo.
Marine biologists study biological oceanography and the associated fields of chemical, physical, and geological oceanography to understand marine organisms.
Marine science recreates key role in the ongoing search to understand our world and to control its resources.
The interdisciplinary nature of the Marine Science curriculum will organise students to analyze deeply such co occuring issues as environmental alter, human clashes on the ocean, and biodiversity.
Thus, Marine biology is the study of marine organisms, their behaviors and relation with the environment.
