<h2>Inbreeding </h2>
Explanation:
Inbreeding is defined as the formation of offspring which results from the mating of two closely related organisms
Inbreeding affects allele frequencies and genotype frequencies in a population in following ways:
- Inbreeding increases homozygosity
which in turn decreases the biological fitness of a population because there are chances that offsprings will be affected by deleterious traits in this case
- Inbreeding itself does not cause evolution, because allele frequencies do not change in the population as a whole
Answer:
An advantage to heterospory is endosporic gametophyte.
The endosporic gametophyte do permits for embryonic formation. It prompts it to have a reduced vulnerability to varying form of environments.
The second advantage that heterscopy could offer to plants is ensuring of a well apportioned nutrient filled environment.
The well apportioned nutrient filled environment is formed as a result of the megasporangium been adhered to the sporophytic plant body. This sees to promote a good formation of the embryo.
A further advantage of heterscopy is the aftermath of fertilization.
This integument is hard as it is necessary to preserve the female gametophyte and embryo.
According to the image, X is for attracting pollinators, Y is for the production of pollen, and Z is for the production of eggs
<h3>Parts and functions of flowers</h3>
The image shows the different parts of a typical flower.
X is a petal. Petals are usually colorful and serve to attract insect pollinators to flowers.
Y consists of the anther and the stigma. Both represent the male organ of the flower and produce the male gametes, otherwise known as pollens.
Z consists of the stigma, the style, and the ovary. They all represent the female reproductive organ of the flower. Pollen lands on the stigma, travels through the style, and reaches the ovary. The ovary houses the ovule or the eggs.

Answer: Concentrated in certain areas
Explanation:
Volcanoes are usually formed as a result of collisions or other activity between plates at plate boundaries.
As a result, they are more usually concentrated in zones where there is more plate activity such as at the edges of continents, on islands and beneath the seas in certain areas because this is where plates usually collide with each other.
Answer:
Glycolysis:
Glycolysis is the primary step of cellular respiration in which glucose molecule is broken down to pyruvate in a set of reaction and produce energy. It generates two molecules of pyruvate, ATP, NADH and water. The process takes place in aerobic as well as anaerobic conditions in the cytosol of the cell cytoplasm.
Significance: generate pyruvate for the next stage, pyruvate oxidation, and release four ATP molecules while spends two ATP molecules in glycolysis, for a net gain of two ATP molecules.
