Incomplete dominance produces a new heterozygous phenotype such as the purple color in this example
Answer:
Estrogen and progesterone are both involved in preparing the endometrium for embryo implantation. Estrogen helps to ensure conception by increasing the amount of secretory glands in the uterus. Estrogen also increases blood supply to the endometrium.
Progesterone is crucial for embryo implantation and maintenance of pregnancy. Progesterone also enlarges secretory glands that produce carbohydrates, proteins and mucin that are required for embryo nourishment before implantation. Progesterone stabilizes endometrial muscles to prevent them from contracting during pregnancy.
Explanation:
- Estrogen and progesterone are steroid hormones of the reproductive system. Estrogen helps in conception whereas progesterone maintains pregnancy.
- Estrogen is secreted during the follicular phase of the menstrual cycle that promotes the growth and maturation of follicles in the ovary.
- Estrogen also induces oestrous behavior in females.
- Secreted by the corpus luteum, progesterone is also a steroid hormone, responsible for implantation of the embryo in the uterus.
By diffusion. Letter c.
Diffusion occurs when the smell of the bread "sticks" to the air and if the air travels from a room to another, the smell will go with it.

Answer:
TYPE OF LIQUID SUBSTANCE RECEIVED
Explanation:
The independent variable in an experiment is the variable that the experimenter deliberately changes or manipulates in order to bring about a response in the dependent variable/measured variable.
In this experiment, the TYPE OF LIQUID was changed for each group of plant in order to see how it affects how the plants grew. Hence, the TYPE OF LIQUID is the independent variable while the dependent variable is the plant growth, which is dependent on the independent variable.
The answer is; Biodiversity resulting from few ancestors
Adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. The parts of the population in the different ecologies begin to adapt to their local environments. Due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. They, therefore, diverge to different species sharing a common ancestor.
