The first is incorrect because the more massive an object, the more gravitational force acts on it.
The second is false because the gravitational force decreases with distance. It's why the outer planets are usually smaller.
The third is true. It depends on both mass and distance and attracts two objects together.
The fourth is false because temperature and pressure have nothing to do with gravity.
Answer:
Genetic variation that alter gene activity or protein function can introduce different traits in an organism. If trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
Answer:
Glucose (sugar)
Explanation:
We know that plants take in carbon dioxide and returns it in a form of oxygen. For the plant to be able to make oxygen they need to get power. The power is the sun rays and that is mixed with the CO2, making glucose. Anything that uses photosynthesis is a producer, so it makes its own food.
Darwin's proposed mechanism for evolution is natural selection. Natural selection allows species to respond to their surroundings through time, or to become progressively excellently-suited. Natural selection is environmentally based and involves established heritable variation within a population.
They lead to changes in species over time:
- Darwin suggested species will evolve over time, new species originate from pre-existing species, and all species share a common ancestor with each other.
- In this framework each organism has its own special set of heritable i.e genetic variations from the common ancestor that have slowly developed over very longer periods of time.
- Parroted branching activities that isolate new species from a common ancestor create a multi-level tree that connects all living organisms.
