The zygote simply is the fertilized ovum or egg cell or female reproductive cell. It is the result of the process of fertilization of the fusion of the male reproductive cell (gamete) and the female reproductive cell ( gamete). In human, the zygote is the resulted cell of fertilization of the sperm and the ovum. It is diploid or 2N which means it contains two sets of chromosomes; one set from the male and the other from the female.
The gamete is the reproductive cell. There are two types of gametes; male gamete and female gamete. In human, the male gamete is called the sperm and the female gamete is called the ovum. The gamete is the last stage of the reproductive cells to be completely formed.
Fertilization is the fusion of the male gamete and the female gamete to form the zygote. Fertilization may be external as in fish or internal as in human.
The answer should be C, the heart and the blood vessels.
The heart acts as a pump in the circulatory system. It pumps blood to organs and tissues all around the body. Meanwhile, the blood vessels (arteries, veins, and capillaries) help transport the blood to tissue and cells and back to the heart. Each type of blood vessel has their own function.
The brain is not involved in this system, as the whole circulation process does not require any us to make any decision.
In addition, there's also one structure that is in the blood vessels, but technically not another item for the circulatory system. That's valves, they are like flaps that ensure blood flowing in one wag direction and to prevent the back flow of blood.
So, the answer is C.

ANSWER:
Electromagnetic energy is monitored by scientists forecasting future space weather
EXPLANATION:
Electromagnetic energy has such type of waves which propagate or radiate through space, carrying photons. Electromagnetic energy has radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays.Space weather includes any activity happening in space that might affect Eath's environment.Space weather can interrupt mobile signals,air communications and can damage our satellites.So Electromagnetic waves are monitored to control all the above situations.
