1. identify the process used to form the covalent peptide bonds that join amino acids into a polypeptide

2. the change in the amino acid sequence illustrated in figure 1 caused a change in the shape of receptor x. based on r groups of the original and substituted amino acids, explain why receptor x changed shape.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

the planets have a circular orbit around the sun.

it can affect the plants by how hot or cold the temperature

explanation:

it can affect the plants by how hot or cold the temperature is and the amount of precipitation can affect the plants cause it needs to have reasonable amount
