Answer:
B
Explanation:
because it doesn't protect vital organs
Answer: the glomerular endothelium cells, the basement membrane, and the Podocyte processes...
Explanation:
The formation of urine by the kidneys occurs in 3 stages described at following:
- Glomerular Filtration - It is the 1st stage in the formation of urine. In this step large amount of liquid is filtered through the membrane from glomerular capillary to Bowman's capsule;
- Tubular Resorption - At this stage, water and some solutes are reabsorbed from the tubules into the blood;
- Tubular Secretion - In this last step occurs the secretion of substances from the blood to the tubules.
This first stage occurs in the glomerular capillaries where part of blood that reaches the glomerulus is forced to pass under pressure by a filtering barrier. This barrier is called the glomerulus filtration membrane. The glomerulus filtration membrane consists of 3 layers, two of them from the capillary (basal membrane and endothelium), and one formed by Bowman's capsule epithelial cells. The endothelial layer, as in the other capillaries, has thousands of pores called fenestrations. These pores allow the passage of all plasma except blood cells. Already the basement membrane is formed by a tangle of protein fibers that prevent the passage of larger proteins. Finally, the outermost layer is formed by the epithelial cells. Bowman's capsule protruding over the basement membrane. These cells are called podocytes since their projections resemble feet.
The general term for any bone projection is called a bony prominence. There are various specific ones for different bones e.g. tubercles, maleolus, etc.
Answer:
Cations are ions that are positively charged. They form when they lose an electron because they would have more protons than electrons. In your problem you have for example potassium (number three).
Iodine is a cation because it lost one electron. The ion symbol then would be:
I ⁺
So this is your clue. If it has a positive or a plus sign on top, that would make it a cation. Another clue would be if it LOST an electron, then it is a cation.
An anion, on the other hand, is negatively charged, because they gain electrons, making the electrons more than the protons. In your problem, you have Iodine as an example (number one).
Iodine gained one electron and the ion symbol would be:
I⁻
So again that is your clue for anions, they have a negative or a minus sign on top of the symbol. If they GAINED an electron, that would make them an anion.
Naming monoatomic anions is easy. They are named with the suffix -ide at the end. (Cations retain their name). For example Sulfur (number two).
Sulfur is an anion that gained two electrons with an ion symbol of:
S²⁻
So from the name <u>Sulfur</u><u> </u>the name will change into "Sulfide" and its name will now be <u>Sulfide ion. </u>
C. Competition: fight between the two animals over food or any resource
