Answer:
Neither A nor B is correct
Explanation:
Hydrologic cycle is the sequence of different conditions through which the water passes from oceans to clouds, precipitates as rains, comes to the rivers and finally reaches the ocean.
This first statement in the question said that water will end up in the river which is not true because water from the river ultimately ends in the oceans because all the rivers terminate in the oceans finally.
The second statement is also wrong because when water from one ocean vaporizes and becomes cloud, it can travel large distances as clouds in the effect of wind and thus may get precipitated in the form of rain in some other part of the world. So, it is not necessary that the water will end up in the same ocean.
Proteins are polymers of twenty-two standard alpha-amino acids that are joined by peptide bonds.
<u>Structure of amino acid</u>-It is made up of compounds containing carbon, nitrogen, oxygen, and hydrogen. In an amino acid, the positively charged amino group and the negatively charged carboxyl group are attached to the same carbon atom (alpha carbon). The 22 amino acids differ from one another because of the side chain attached to the central carbon atom. The central carbon atom is also attached to the H atom.
<u>Proteins have four levels of structural organization</u><u>- </u>
- Primary structure
- Secondary structure
- Tertiary structure
- Quaternary structure
Quaternary structure-It is made up of two or more polypeptide chains. Each polypeptide chain is called a subunit. The polypeptide chains in the quaternary structure of a protein can be similar or different. The polypeptides are stabilized by noncovalent bonds such as hydrophobic interactions, hydrogen bonds, and electrostatic interactions. For example-Hemoglobin.
The answers for the blanks are-
1.Noncovalent, 2.amino, 3.carboxyl, 4. quaternary structure

Answer:
The answer is 'B'
Explanation:
Warm air toward high latitudes and cool air toward the equator.
Often, El Niño is accompanied by La Niña, as if warm seawater is bubbling back and forth across the Pacific Ocean. The development of El Niño is associated with trade winds. Appears when they are weaker than usual, and La Niña occurs when they are stronger than usual.
