Answer:
Diffusion
Explanation:
The process by which substances move from areas of higher concentration to areas of lower concentration is called diffusion.
For example:
Substance moves across a cell membrane without using the cell's energy tends to move away from the area where it is more concentrated.
It is known as passive transport.
It is the process in which substance without using the cellular energy tend to move down the concentration gradient.
It is also known as simple diffusion.
When perfume bottle is open particles spread in air due to difference in concentration from bottle to out side environment.
While,
In case of active transport substance move against the concentration gradient i.e to wards the area of higher concentration.
This process require energy.
Answer:<u><em>When water freezes, it contracts, decreasing the water level in a lake. Water in a lake freezes from the bottom up, killing most aquatic organisms. When water in a lake freezes, it floats, providing insulation for organisms below.</em></u>
Explanation:
B I think is the answer sorry if I’m wrong
Answer:
there are three of them, convergent, divergent, and transform
Explanation:
Convergent: where two plates are moving towards each other
Divergent:Where two plates are moving AWAY from each other
Transform:Where two plates SLIDE past each other
18 chromosomes would be in each of its gametes.
What are chromosomes?
the nucleus of most living cells contains a threadlike structure made of nucleic acids and proteins that carries genetic information in the form of genes.
There are 23 pairs of chromosomes in humans. The chromosome's distinctive structure helps to increase the integrity of the DNA while also keeping it securely packed with histone proteins to fit within the cell. For instance, a single cell's DNA will be 6 feet long when unraveled; from this, it is clear why each cell's nucleus needs to be packaged.
according to the given information:
number of chromosomes: 36
36√2 is 18
18 chromosomes would be in each gamete.
