Seasonal changes occur because of earth's tilt
erastova [34]3 years ago

Answer: The Earth's tilt.

Explanation:

The reason why the Earth has seasons is because our planet’s axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane. This tilt in the axis is called obliquity.

During a yeartime, there is no variation in the angle of tilt. However, the orientation of Earth’s tilt with respect to the sun changes as we orbit the sun. This change causes the different seasons.

A protein that contains more isoleucine, phenylalanine and leucine than asparagine, lysine and arginine is most likely ________.
Snezhnost [94]

Answer:

The correct answer is: Hydrophobic, Hydrophobic.

Explanation:

  • Proteins are made up of polypeptide chains which are formed by the polymerization of amino acid molecules, linked together by peptide bonds.
  • The amino acids can be broadly classified into non-polar and polar.
  • The non-polar amino acids can be defined as those amino acids whose side chains possess hydrocarbon molecules only. They do not possess any charge and are incapable of forming hydrogen bonds with water molecules. They tend to avoid water and so they tend to remain buried into the interior of a protein. Examples can be illustrated as Leucine, Valine, Isoleucine, Phenylalanine, etc.
  • The polar amino acids can be defined as those amino acids whose side chains either possess a charge (positive or negative) or a hydroxyl group which is capable of forming hydrogen bonds with water molecules. As they tend to form hydrogen bonds with water molecules they are usually found on the surface of the proteins. Examples can be illustrated as Lysine, Arginine, Serine, Asparagine, etc.
