There is gravity everywhere. It gives shape to the orbits of the planets, the solar system, and even galaxies. Gravity from the Sun reaches throughout the solar system and beyond, keeping the planets in their orbits. Gravity from Earth keeps the Moon and human-made satellites in orbit. It is true that gravity decreases with distance, so it is possible to be far away from a planet or star and feel less gravity. But that doesn't account for the weightless feeling that astronauts experience in space. The reason that astronauts feel weightless actually has to do with their position compared to their spaceship. We feel weight on Earth because gravity is pulling us down, while the floor or ground stop us from falling. We are pressed against it. Any ship in orbit around the Earth is falling slowly to Earth. Since the ship and the astronauts are falling at the same speed, the astronauts don't press against anything, so they feel weightless.You can feel something very like what the astronauts feel for a moment in a fast-moving elevator going down or in a roller coaster, when you start going down a big hill. You are going down rapidly, but so is the roller coaster or the elevator so for a second you feel weightless.

Answer: increases the chance that deleterious and lethal recessive alleles will combine to produce homozygotes with harmful traits.
Explanation:
Unlike crossbreeding, inbreeding encourages the mating of organisms of same species; thus preventing the introduction of other desirable traits and a state of continuous monopoly in transmission of inherited traits (both beneficial and deleterious)
Energy would be passed from the deer to the wolf if the grasses had 5000 kcal is 50kcal.
50kcal Energy would be passed from the deer to the wolf if the grasses had 5000 kcal.
According to 10% Energy law given by Lindmann, only 10% of energy is transferred to the lower level to the higher level.
According to the given question,
Grass = 5000kcal
This indicates only 10% energy will be transferred from Grass to Deer according to the law.
Deer = 10% of 5000kcal = 500kcal
This indicates only 10% energy will be transferred from Deer to Wolf according to the law.
Wolf = 10% of 500kcal = 50kcal
The rest energy is lost in the Respiration and only 10% gets transferred.
So, Energy would be passed from the deer to the wolf if the grasses had 5000 kcal is 50kcal.

The cell membrane is made of a protein layer that is sandwiched between 2 phospolipid layers. It has pores that allow selective passage of substances in and out of the cell.
