Answer:
Animal cells tend to do best in an isotonic environment, plant cells tend to do best in
a hypotonic environment. This is demonstrated in the attached PDF.
Explanation:
A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.
I hope this helps. If not I am really sorry!
The answer would be D, as even though both velocity and speed may share similar resultants in this scenario, speed is a scalar, while velocity is a vector. Thus, velocity can have direction and move negatively (the opposite direction from which it started) while speed is a measurement of quantity.

Answer:
1. Adenine
2. Thymine
Explanation:
These are the four nitrogen bases of DNA nucleotides. It's just something that you have to memorize in order to be able to successfully study DNA. In case you are asked which base pairs with which, always remember this saying about base pairs: A and T, and, G and C.
