Mirror neurons are activated by performing an action or seeing another perform the action. They were found by chance during experiments with monkeys, when researchers discovered that the same neurons that fired while performing a behavior also fired while observing the behavior. Mirror neurons have been linked to motor skill development, imitating another's behavior, feeling empathy for another, understanding or comprehending social behavior, and language development. Answer for E2020
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:
Crossing over between segments of homologous chromosomes.
Explanation:
Crossing over happens during prophase I of meiosis I
I believe the ratio of C to H to O in simple sugars or monosaccharides are 1 C : 2 H : 1 O or 1:2:1.
The DNA carrying a silent mutation will have no gene expression or result on the phenotype or physical appearance of the organism. Silent mutations code for the same amino acid resulting in more genetic diversity, having a genotypic advantage, but providing no noticeable differences.
