Answer:
Cells divide twice
Explanation:
Meiosis may be defined as the process of cell division in which a single cell divides to give four daughter cells and each daughter cells have half number of chromosomes.
Meiosis is also known as reduction division as the chromosome number reduces upto half in the progeny cells as compared with the parent cell. The cells divide twice in meiosis and give rise to four daughter cells.
Thus, the correct answer is option (4).

5. The phenotypic ratio is 9:3:3:1 where 9 combinations will produce offspring with both dominant phenotypes (dimples and brown hair), 3 will produce offspring with one dominant phenotype and one receive phenotype (dimples, blonde hair), 3 will produce offspring with one receive phenotype and one dominant phenotype (no dimples, brown hair), and one will produce offspring with both recessive phenotypes (no dimples, blonde hair)
Answer;
Septicemia
The condition where pathogens multiply in the blood is called Septicemia.
Explanation;
Septicemia refers to an infection of the blood that results from the presence of pathogens such as bacteria in the blood. The onset is signaled by a high fever, chills, weakness, and excessive sweating which follows a decrease in blood pressure.
The levels of organization in an organism may be broken down, from simplest to most complex, as:
1. Cell
2. Tissue
3. Organ
4. Organ system
5. Organism
A cell is the basic building of life and almost all cells in an organism's body are far more similar than they are different in both structure and function. Next are the tissues, which are groups of cells combined to carry out a special task. These tissues combine to form an organ, which a large part of the body that partakes in an important task, such as the heart pumping blood. Then is the organ system, which may contain multiple organs all working in conjunction to achieve a change in the organism's body. Finally, the organ systems combine and form the organism. The degree of complexity therefore increases.
