Answer:
all living organisms are formed from cells
all living cells reproduce
cells are the basic structural and functional unit of life
Explanation:
Answer:
B
Explanation:
All cells from the body came from a single cell ( fertilization of egg and sperm). All the cell have the same instruction in them. They however undergo certain changes base on the site of their function in process described as cell specialization. During this differentiating process, certain genes are activated to produce proteins that enables specific functions. Example include the myosin present in abundance in muscle cells but not in lens cell while the lens cell have crystallins in abundance for it adapted activities which the muscles cells lack. others include the root hair cell specially adapted for absorption, the nerve cells for transmission of electrical impulses. This cells generally have certain character controlled by the activated genes which are repressed in others.

Answer:
Explanation:
Common names are local names that are given to organisms. These names are widely and locally accepted even within scientific bodies in order to avoid the rigors of having to use latin names of organisms.
Some of the limits of using common names are:
1. They can depend on geography: some common names are restricted in their use based on their acceptance by set of people. In some other climes, they might not be accepted. This is one big limitation in using common names.
2. They often use multiple words: within a particular area, an organism can be called different names. This is yet another big limitation of common names.
3. They are can be descriptive or non-descriptive of the organism: some common names are descriptive and they can easily tell us about an organism. Others might not even relate to to the organism at all.
4. They can be in different languages: Most languages have a common name for all organisms. This pose a serious scientific barrier when studying such species.
