Answer:

Stars do not emit sufficient light to help locate them accurately in the night sky. The revolution of Earth makes the sun and the planets move on the ecliptic with respect to the stars.

Explanation:

Rotation and revolution causes changes in star charts. When the Earth rotates, move a way from the sun and when you have rotated far enough it will be nights and you will observe stars but as the seasons changes you will see different stars because u will change to different position. The revolution of the Earth make the stars and sun move ecliptic.

Based on the formula for kinetic energy, how will the temperature change if you increase the average velocity of the molecules i

ICE Princess25 [194]

Answer:

Temperature will increase

Explanation:

As we know

$KE = \frac{2}{3} RT$

Where KE represents the Kinetic Energy, R represents the gas constant and T represents the temperature.

As the kinetic energy increases, the velocity of the gas molecules increases due to which the gas molecule start moving rapidly and hence exerts higher amount of force on the wall of the container in which it is kept.

The higher force leads to generation of higher pressure and hence the higher temperature.

There are four classes of organic molecules that are essential to all living organisms.

1. Carbohydrates:

Components: monosaccharides. Functions: energy for cell, raw material, energy storage, and plant cell support Ex: glucose, starch, glycogen, cellulose

2. Lipids (dont form polymers): Components: glycerol, fatty acid, components of a fat molecule Functions: energy storage, cell membrane components, and hormones Ex: fats, phospholipids, and steroids

3. Proteins:

Components: amino group, carboxil group, R group, and amino acid Function: enzyme, structural protein, movement, transport, communication, defense, storage, receive signals Ex: lactose, hair, tendons, muscles, hemoglobin, signal proteins, antibodies, egg albumin, receptor protein

4. Nucleic acids:

Components: phosphate group, nitrogeneous base, ribose or deoxyribose, nucleotide Functions: heredity, DNA

Ex: code for proteins, DNA and RNA

because they have thicker walls

Explanation:

blood is punped our of the heart very fast which means it would need a blood vessel witch thick walls to withstand the pressure. thin walls would cause the blood vessle damage and may evwn break as it wouldn't be able to withstans the pressure.
