The right answer is It produces male and female sex cells.
Meiosis is the process of double cell division allowing the formation of gametes, or sexual cells in eukaryotic organisms. It differs from mitosis, somatic cell division, which takes place only in a time. From a diploid mother cell, we obtain four haploid daughter cells with different genetic material.
Answer:
Explanation:
Plant transport systems move energy from leaves and raw materials from roots to all their parts. The xylem (tissue) moves water and minerals obtained from the soil to all other parts of the plants.
Answer:
The leukocyte, commonly known as a white blood cell (or WBC), is a major component of the body’s defenses against disease. Leukocytes protect the body against invading microorganisms and body cells with mutated DNA, and they clean up debris. Platelets are essential for the repair of blood vessels when damage to them has occurred; they also provide growth factors for healing and repair.Although leukocytes and erythrocytes both originate from hematopoietic stem cells in the bone marrow, they are very different from each other in many significant ways. For instance, leukocytes are far less numerous than erythrocytes: Typically there are only 5000 to 10,000 per µL. They are also larger than erythrocytes and are the only formed elements that are complete cells, possessing a nucleus and organelles. And although there is just one type of erythrocyte, there are many types of leukocytes. Most of these types have a much shorter lifespan than that of erythrocytes, some as short as a few hours or even a few minutes in the case of acute infection.

Explanation:
Answer;
Carbon
Explanation;
-The large diversity of shapes of biological molecules is possible because of the extensive presence of carbon in the molecules.
-The major classes of biological molecules that are important for all living things are carbohydrates, lipids, proteins, and nucleic acids. These molecules differ in structure and function, in part, because of different functional groups.
All organic molecules contain carbon atoms. Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements.
-Carbon qualifies as the foundation element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.
Answer:
different proteins
Explanation:
All the cells of the body are derived from same cell still different cells have different characteristics or phenotypes. For example, the hemoglobin is present in RBCs only not in any other cell. This is because of a process called gene expression.
This process regulates expression or repression of different set of genes. This makes embryonic cells to become specialized cells that is to perform a specific function. The gene contains DNA which gets transcribed to RNA and then to proteins. The different proteins provides different specificity to cell.
