Answer:
Flowering plants begin as seeds. These seeds store energy and food within them long enough to reach the right environment and germinate. Germination is the development of a plant, growing from a seed into a seedling. Seedlings are the second stage of a flowering plant's life. This is when their roots begin to form and photosynthesis can begin. Next comes the growth period. After the seedling is planted, it requires a lot of food and energy as more leaves begin to emerge. The next stage of a flowering plant's life is the flowering stage itself. This is when buds and flowers begin to sprout. It enters the reproductive stage and pollination begins, allowing more seeds to be sown.
Answer:
Natural selection is the process of which forms of life having traits that better enable them to adapt to specific environmental pressures, such as predators, changes in climate, or even competition for food or mates. As the species will tend to survive and reproduce in greater numbers than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations.
Answer:
1. Lupus
2. Cardiovascular disease
3. Huntington disease
4. Cancer
5. Diabetes
Explanation:
A disease can be defined as any harmful or abnormal deviation of the body of a living organism from its functional state or normal structure, which is typically accompanied by certain signs and symptoms.
Basically, a disease negatively affects the function or structure of the body of a living organism.

1. Lupus: occurs when the immune system attacks the body. It is referred to as an autoimmune disease.
2. Cardiovascular disease: is often caused by obesity resulting from overeating and poor nutrition.
3. Huntington disease: is caused by DNA changes in a single gene and affects the nerve cells in the brain.
4. Cancer: is caused by uncontrolled cell growth.
5. Diabetes: occurs when the pancreas does not produce enough insulin, or the body does not respond properly to it.
Answer:
d. Two of the above explanations are correct.
Explanation:
A frameshift mutation is commonly known as a genetic mutation that occurs as a result of the indels such as the addition or removal of certain nucleotides in the sequence of a DNA that is indivisible by three. In the presence of addition or removal, the reading frame from the initial translation to a different one. Thus, the correct option is option d.
