1. prokaryotic cells
2. nucleus
3. The Cell Theory.
Answer:
Structure of bacteria:
Bacteria is a unicellular and prokaryotic organism i. e. made of one cell and no membrane is present around the nucleus. They are found in many shapes such as rods, spherical and cylindrical etc.
Reproduction in bacteria:
In bacteria asexual reproduction occurs such as binary fission. In binary fission, the body of organisms is divided into two equal parts and each part becomes a new organism.
Infection caused by bacteria:
Bacteria cause infection by entering the host cell and starts reproducing and after that they attack on the neighbor cells.
Answer:
Density, dispersion, growth
Explanation
Population refers to the total number of all members of a species occupying a particular area or habitat at a given time. Populations are not static but change in size, structure and organization. Some of the characteristics of population are:
- Density which refers to the number of members of a species per unit area or volume.
- Dispersion refers to the spread and distribution of individuals of a species within a habitat.
- Growth is the rate of increase or decrease in the number of individuals in a population which is balanced by birth rate and death rate.
The issues that affect population include competition, predation, emigration, diseases and parasites.

Explanation:
The bone marrow is the soft tissue inside bones that helps form blood cells. It is made up of a liquid part and a more solid part. And it is found in the hollow part of most bones. The bone marrow is
The biopsy and bone marrow aspiration are usually done at the same time. Together, these two procedures may be called a bone marrow study.
Marrow aspiration is the removal of a small amount of this tissue in liquid form for testing. Bone marrow biopsy and bone marrow aspiration are procedures that allow samples of bone marrow (the spongy tissue inside some of the longer bones) to be removed and tested. In a bone marrow biopsy, the doctor uses a needle to remove a sample of the solid part. In a bone marrow aspiration, a needle is used to remove a sample of the liquid part.
<u>Bone marrow aspiration and biopsy may indicate whether the bone marrow is healthy and producing normal amounts of blood cells</u>. Doctors use these procedures to diagnose and monitor blood and marrow diseases, such as some cancers and fevers of unknown origin. <u>After the procedure, it is important to control the wound so that it does not become infected, and to monitor vital signs.</u>
