Answer:
hypothesis
Explanation:
A hypothesis is a possible logical answer to a scientific question, based on scientific knowledge. A prediction is a statement that tells what will happen under certain conditions. Evidence is any type of data that may either agree or disagree with a prediction, so it may either support or disprove a hypothesis.
I think photosynthesis is mainly from sunlight to make energy for food for the plants
Answer:
Mitochondria
Explanation:
<em>The mitochondrion is a relatively small, double membrane organelle that primarily serves as the site of oxidative phosphorylation; a process that generates energy in the form of ATP for the running of cell's activities.</em>
Hence, a cell that requires a lot of energy might need a large number of mitochondria in order to meet the energy demand of the cell.
The answer is mitochondria.
True
Explanation:
The statement that when the distance between the balls decreases, the size of arrow increases because it shows the gravitational pull between the two balls which increases is true.
According to Newton's law of universal gravitation:
"The gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of their separation".
Mathematically, the law is written as:
F = ![\frac{G m_{1} m_{2} }{r^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BG%20m_%7B1%7D%20m_%7B2%7D%20%7D%7Br%5E%7B2%7D%20%7D)
F is the gravitational force
G is the universal gravitational constant
m is the mass of the body
r is the distances between them.
We see that the less the distance between the two bodies the more the gravitational force they have.
