Answer:
Homeostasis is the ability to maintain a constant internal environment in response to environmental changes so organism must need it so they can be balanced internally in response to the environment .

Answer:Mass of bullet, m=20g= 0.02kg
Velocity of bullet, v=100m/s
Mass of gun, M=5kg
Let recoil velocity of gun =V
Before firing, the system (gun+bullet) is at rest, therefore, initial momentum of the system =0
Final momentum of the system = momentum of bullet + momentum of gun
=mv+MV=
=2+5v
we know Final momentum = Initial momentum
i.e., 2+5v=0
5V=−2
v=-0.4m/s
Negative sign shows that the direction of recoil velocity of the gun is opposite to the direction of the velocity of the bullet.
Answer:
C. Mitosis produces cells that are identical genetically, while meiosis produces cells that differ.
Explanation:
Answer choice A is incorrect because mitosis actually creates identical cells while meiosis creates 23 genetically unique pairs.
Answer choice B is incorrect because neither produces "quicker" or "easier"
Answer choice D is incorrect because it is actually the opposite: Mitosis only has one cell division that provides two daughter cells, while Meiosis has two divisioins that result in four cells.
Thus, the most logical answer is C. Feel free to message me if you have any more biology questions!!
