Answer:
B) Tissue is made of different types of cells.
D) Organs are made of different types of tissue.
Explanation:
The tissues are made of different types of cells. The organs are also made of different types of tissue. There is no need of same types of tissues to make organs. Thus, option (B) and (D) is correct answer.
The four major types of germs are bacteria, viruses, fungi, and protozoa. They can invade plants, animals, and people, and sometimes they can make us sick.

There is no absolute reason as to how they survive besides organisms learning to adapt. In order to live in a polluted environment the animals have to survive and learn to adapt.
I believe (not sure) that the answer is B, viruses must invade their host before being able to reproduce.
I remember seeing a diagram of the general life of a virus, and I remember seeing the virus sticking to a cell, merging in, and reproducing thereafter (sort of like a factory). Once again, I am not sure and the answer may as well be another one.
