Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
There are choices for this question namely:
1. Sterile
2. Reproductive
3. Both
4. Neither
The correct answer is that flowers are a collection of reproductive tissue produced by flowering plants (angiosperms). The flower is a reproductive organ of the plant. It is composed of the male organ (stamen) which produces the pollen and the female organ (ovary) which receives the pollen. Once the ovary receives the pollen either from the same plant or from another through pollination, the ovule (part of the ovary) will then become the seed and the ovary will become the fruit. The seed is the "embryo" of the plant wherein if planted, it will grow to a new plant.

3.Cells grouped together to perform a specialized function are known as a tissue. Tissues arranged together to perform a special function are known as an organ. Organs that together to perform the many functions of the body as a whole are called a system. ... Any abnormal development of tissues or organs.
4.Molecules are the chemical building blocks of all body structures. A cell is the smallest independently functioning unit of a living organism.
5.Tissue. Word used to denote a living thing. Organism. Level made up of a group of tissue working together. Organ.
Answer: Option C.
Inefficient oxygen transportation.
Explanation:
Sickle cell anaemia is an inheritable condition in which the red blood cells cannot carry oxygen to the organs or whole body because the red blood cells shape has been distorted and is sickle in shape. In this condition there is not enough red blood cells to carry oxygen in the blood.
Red blood cells function to transport oxygen in the blood because of the haemoglobin molecule present in them.
This can damage the organs nerves,lungs, livers spleen e.t.c
