Answer:

A. MeONa

Explanation:

One of the methods to prepare alkenes are eliminations.

The E2 reaction (for elimination, bimolecular) occurs when an alkyl halide  is treated with a strong base, such as hydroxide ion or alkoxide ion (RO⁻).

It is the most common mechanism that occurs for an elimination.

The methoxide ion is a strong base that will attack the neighboring hydrogen of the halide ion and will start removing H⁺ at the same time that the double bond of the alkene begins to form and the group X begins to leave.

Then, the neutral alkene is produced  when the  C – H link and X group has left  with the electron pair of the bond  C – X (mechanism in attachment).

Therefore, MeONa would be an appropiate reagent.

The osmolarity (osmotic concentration) of the filtrate does not change from the beginning to the end of the promixal convoluted
Alex Ar [27]

Answer:Although the kidneys are the major osmoregulatory organ, the skin and lungs also play a role in the process. Water and electrolytes are lost through sweat glands in the skin, which helps moisturize and cool the skin surface, while the lungs expel a small amount of water in the form of mucous secretions and via evaporation of water vapor.

Kidneys: The Main Osmoregulatory Organ

The kidneys, illustrated in Figure 22.4, are a pair of bean-shaped structures that are located just below and posterior to the liver in the peritoneal cavity. The adrenal glands sit on top of each kidney and are also called the suprarenal glands. Kidneys filter blood and purify it. All the blood in the human body is filtered many times a day by the kidneys; these organs use up almost 25 percent of the oxygen absorbed through the lungs to perform this function. Oxygen allows the kidney cells to efficiently manufacture chemical energy in the form of ATP through aerobic respiration. The filtrate coming out of the kidneys is called urine.
