Estrogen. Estrogen is a major hormone involved in the reproductive system and has a major role in it. The role of estrogen, mainly, in the reproductive system is to maintain or regulate the menstrual cycle as well as the preparation phase for pregnancy.

Estrogen

Hormones are a part of the reproductive process of producing an offspring. They are the one responsible for producing both sperm and egg cells. The reason why some cells do not respond to certain hormones is that some hormones only react to specific cells with specific receptors for the active hormone.

The answer is 1. The testes is the one responsible for producing the hormone for sperm cells. Testosterone is the specific hormone for producing sperm cells.

Cell A

This is important in reproduction because fertilization will not occur and there will be no zygote and embryo formation if there is no fusion of the sperm and egg.

The cells produced in process 1 is a diploid cell and the cells produced in process 3 ends in four daughter cells.

The answer is 1. Both male and female gametes are produced in the ovaries and testes. The other term for female gametes are egg cells and male gametes are sperm cells.

1

The answer is 4. Internal fertilization happens after the sperm and egg cell meet together. It happens in the fallopian tube which is only present in a female reproductive system.

The placenta is the source of all nutrients from the mother to the child. It serves as the organ that supplies nourishment to the developing fetus. The group of hormones that could alter processes in the placenta includes progesterone. This hormone is responsible for maintaining pregnancy. The uterus is the one responsible for the developing fetus and the place where the placenta develops.

Hormones are a part of the reproductive process of producing an offspring. They are the one responsible for producing both sperm and egg cells. The hormones responsible for the egg cells are estrogen and progesterone while the hormone responsible for the sperm cell is testosterone.

The uterus is where the developed embryo is stored for further development and maturity. It is also the site where the placenta is formed as it is the source of nutrients for the developing fetus.

In order to produce a successful pregnancy. A fetus must develop normally and must be avoided of any harmful effects of the environment. These harmful environmental factors include cigarette smoking, drinking alcohol or exposure to certain hazards like radiation.

Asexual reproduction requires only one parent and have the same genetic combination as the parent. The resulting offspring may have different variations.

Meiosis is a type of cell division wherein the resulting cell is four daughter cells which does not have the same number of chromosomes but rather only half of the parent cells. This usually occurs during the formation of gametes and spores.

A factor that can be considered why some species lay hundreds of eggs is to be sure that another animal is produced. When laying eggs, predators can eat the eggs and some of the eggs may be lucky enough to be retained.

Fertilization in reptiles and birds must be internal to stay safe from the predators. Living in the wild entails danger and risks of being the meal of a predator. Since reptiles and birds have protective shells after being fertilized, this will serve as their added protection from the wild.

This is because the rate of birth of the human race is greater than the rate of death in a human population. Another reason would be that humans do not easily die, there must be certain factors or hazards needed before a human can die.

Cloning is the process of replicating genes in order to produce an identical type of plant or organism. A cloned flock would be different from a non-cloned flock in that a cloned flock will have the same DNA as the parent flock.

An advantage of having a cloned flock include the convenience of reproduction. Another advantage would be an easy way to reproduce flocks in order to meet the demand.

A disadvantage of a cloned flock is the possibility of having mutations in the genes. These mutations create or may have different manifestations in a flock and may also cause abnormalities or even death.

One reason the farmer would mate his sheep with others is for the purpose of variation in genes. This creates different characteristics or variations in order to decrease the possibility of having mutations.

This would create variations because cloning produces exactly the same DNA or genes as the parent. Mating a parent offspring from the flock with another parent from another flock would create different combinations of genes.

Asexual reproduction requires only one parent and have the same genetic combination as the parent. This occurs because asexual reproduction does not involve the process of transferring genetic information from an egg and sperm cell.

Sexual and asexual reproduction also differ in the process of how they reproduce. Sexual reproduction involves the fusion of the egg and sperm cell and undergoes fertilization and meiosis while in asexual reproduction, the process of reproducing is called mitosis.

A zygote is formed by the fusion of both egg and sperm cells. These cells are called gametes which com from both parents, male and female. The egg cells, as well as, the sperm cells have an equal number of chromosome which is 23.

The genetic content of the zygote will come from both the parent cells fused together, the egg and sperm cell. This fusion would contribute equal amounts of a chromosome, which is half of each parent resulting in a diploid chromosome.

Fertilization occurs right after the egg and sperm cell meet. This event occurs in the oviduct of the female reproductive system. After this, the process of meiosis occurs wherein differentiation occurs and embryo formation.

The uterus is where the developed embryo is stored for further development and maturity. It is also the site where the placenta is formed as it is the source of nutrients for the developing fetus.

One factor that may affect fetal development is the exposure of the fetus to certain hazards from the environment such as tobacco, alcohol or drugs. This certain environmental factors alter the development of the fetus and create different mutations while developing.

One factor sthat may affect fetal development is the exposure of the fetus to certain hazards from the environment such as tobacco, alcohol or drugs. This certain environmental factors alter the development of the fetus and create different mutations while developing.

Estrogen is a major hormone for regulating the reproductive cycle in a female. This hormone keeps the balance and mediate the process of developing female sex characteristics as well as regulating menstrual flow.

Hormones are a part of the reproductive process of producing an offspring. They are the one responsible for producing both sperm and egg cells. The reason why some cells do not respond to certain hormones is that some hormones only react to specific cells with specific receptors for the active hormone
