<h3><u>Answer;</u></h3>
<em>The marrow in the bones of the skeletal system helps produce the cells in the blood, which is the key fluid of circulatory system</em>
<h3><u>Explanation;</u></h3>
- <em><u>Skeletal system is a system in the body that is made up of cartilage and calcified bone that work together by helping in the smooth movement process of the body. </u></em>
- <em><u>Circulatory system on the other hand is a system of the body that is made up of blood vessels that carry blood away and towards the heart. The system helps in transport of oxygen and nutrients in all the body tissues, and also transport of carbon dioxide and wastes out of the tissues.</u></em>
- <em><u>The calcified bones of the skeletal system work with the circulatory system, such that the bone marrow in these bones helps in the production of blood cells such as red blood cells and white blood cells.</u></em>
In terms of parasites vs hosts, it is an organism in which the parasite resides and normally feeds + reproduces.
Answer:
Cholesterol is a structural component of the cell membranes of animals. Because of cholesterol that provides cell membrane structural integrity and fluidity, animal cells need not to have cell walls such as that in bacterial and plant cells.Cholesterol reduces permeability of lipid membranes. ... Cholesterol plays has a role in membrane fluidity but it's most important function is in reducing the permeability of the cell membrane. Cholesterol helps to restrict the passage of molecules by increasing the packing of phospholipids.
Explanation:
Answer:
C. Cohesion of molecules
Explanation:
Cohesion is the interaction of molecules of the same substance together. By the force of cohesion if two drops of water come together they form one. Water has high rates of cohesion due to hydrogen bonds.
This phenomenon also called surface tension and is what allows small insects to stand on water.
Cohesion along with adhesion of water to the walls of the narrow tube generate what is called capillarity. This allows liquids to ascend inside the narrow tubes. As long as the cohesion is less than the adhesion, the liquid will rise until both forces are equal.
