Answer:
A)100mL B)50mL C)The second option D)Hypoosmotic Environment
Explanation:
The average Na concentration in the seas and oceans of the world is around 3,5% which mean that in 100 ml of sea water, there is around 3,5 grams of Na.
The weight of one mol of NaCl is 58,44 grams. For 3,5 grams of NaCl, we get 3,5/58,44 = 0,060 mol of NaCl which is 0,060x1000 = 60 mmol/100ml. According to this and the information given in the question about the secretion of the salt glands', if the average sodium concentration is 600mmol/L, we have 60*10 = 600mmol/L so it would take 100 mililiters of water to excrete.
If the average Na concentration of the salt gland's secretion were 300 mmol/L, only 50 mililiters of water would be needed to excrete the same sodium load.
The second option of secretion is hyperosmotic to seawater because the concentration is higher.
Osmoregulation is the process of balancing the amount of water and salt between the body of the organism and its surrounding environment. For salt glands to be advantageous for osmoregulation, they need to be in a hypoosmotic environment.

The icd-10-CM codes is International Classification of Diseases, Tenth Revision, Clinical Modification.
The icd-10-CM is used for the clinical manifestation of the diseases or the abnormalities detected during the treatment procedures. These codes are used for the reimbursement purpose of the treatment or the diagnostics provided.
B83.8 is a code for the hepatic capillariasis. The code B83.8 is used for billable diagnostics in the case of Helminths infection.
So, the given blank can be filled with B83.8.
The ileum contains villi that project into the lumen and increase the amount of surface area.
Villi are small finger-like structures that project into the lumen of the small intestine. Villi increase the surface area of the intestinal walls for easy and quick absorption of digested food with the addition of digestive secretions. Villi vary in length from about 0.5 to 1 mm. They are usually found in large numbers at the beginning of the small intestine and they reduce toward the end of the tract.
Answer:
nitrogen fixation.
Explanation:
Nitrogen fixation is the process by which the combination of molecular nitrogen oxygen or hydrogen is given to give oxides or ammonium that can be incorporated into the biosphere. Molecular nitrogen, which is the majority component of the atmosphere, is inert and not directly usable by most living beings.
Cells become haploid in cytokinesis of meiosis one because the chromosomes have divided.
