CF is a recessive type of disorder which means that both parents must carry the gene in order for the child to inherit the disease. If the child only inherits 1 copy of the affected gene, then the child becomes a carrier. Carriers do not manifests symptoms of the disease but they can pass the disease to their children.
With both parents as carriers, they will have the following chances: 50% carrier children, 25% affected child, and 25% normal child.
Beacuse to be male you have to inherit the Y chromosome from your dad as the mother would be XX and father XY. so males can only inherit these conditions from their mothers beacuse the alleles for theses conditions are found on the X chromosome
Hello. This question is incomplete. The full question is:
Energy and matter cycle through a beach ecosystem on the Gulf of Mexico. Identify one kind of model you can use to show the path of energy and matter through this ecosystem. Describe one benefit of using that kind of model to show those processes.
Food web; shows energy available at each trophic level for the next group of organisms
Energy pyramid; show all pathways of energy flow in an ecosystem
Food chain; shows a single pathway of energy flowing, making it easy to see which organisms are primary, secondary and tertiary consumers
Answer:
Food chain; shows a single pathway of energy flowing, making it easy to see which organisms are primary, secondary and tertiary consumers
Explanation:
The food chain represents a linear sequence of energy transfer within an environment. This transfer is carried out with a sequence of living beings that serve as food for each other and this food that promotes the transfer of energy through a single path, allowing all levels of transmission to be observed, through primary, secondary and tertiary.

In response to a decrease in the concentration of blood <u>oxygen</u>, the kidneys secrete <u>erythropoietin</u>.
In the field of biology, erythropoietin can be described as a hormone that helps in the production of red blood cells (RBC). As red blood cells are the sites that carry oxygen in the blood, more red blood cells mean that the concentration of oxygen will increase inside the blood.
Erythropoietin, which is also referred to as haematopoietin, is produced inside the kidneys. The interstitial cells of the kidneys are the main sites for the production of erythropoietin.
Erythropoietin is produced by the kidneys as a kind of response mechanism when there are decreased levels of oxygen inside the blood. When the oxygen level in the blood reaches a normal level, the production of this hormone is lowered by the kidneys.
Although part of your question is missing, you might be referring to this full question:
In response to a decrease in concentration of blood __________, the kidneys secrete __________.
calcium; renin
oxygen; erythropoietin
sodium; aldosterone
potassium; ADH
glucose; insulin
