The Earth is more massive than the moon. How will a person’s weight on the moon compare to their weight on Earth?
Rom4ik [11]

Answer:

The weight of a person on the moon is less, compared to their weight on Earth.

Explanation:

Gravitation is a force. Gravity is the force that tries to pull two objects toward each other.

Anything which has mass, also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. So because the moon iless massive than the earth, you will experience a less gravitational pull and therefore a you will experience less weight on the moon compared to your weight on earth.

EXTRA

The Gravitational pull is difined by the force that arises of masses of two objects in relation to their distance.

Earth's gravity is what keeps you on the ground and what causes objects to fall back to earth.

You can experience a change in gravitational pull on earth yourself, in an exelerating or decelerating elevator.

A layer of resin and woody tissue sticks the cones' scales together. The seeds are locked in tight, and the cones can't open unless they're exposed to VERY high temperatures like the type of temperatures that fire provides. This shows they survive through exposing the seeds after forest fires.

A. Measles generates a weak immune response that allows reinfection of hosts, and therefore does not easily evolve escape varian
Doss [256]

The correct answers are:

b. Human influenza a virus evolves escape variants, resulting in a distinctive cactus-shaped phylogeny.  

All types of Human influenza viruses evolve to escape immunity induced by prior infections and vaccinations.

c. Measles experiences strong selection for escape variants, resulting in a phylogeny similar to a nonpathogenic species.  

As a result of measles infection, specific antibody and CD4 and CD8 T cell responses are generated and contribute to virus clearance and protection from reinfection.
