Hey this is late, but if an organ fails, like for example the kidney fails right? So then it affects the heart. and so on, because the kidney helps clean the blood and your body needs blood.
Answer:
Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
A dichotomous key helps you identify unknown specimens based on their traits because there are only two options available per trait. Selecting one from the two options (usually contrasting characteristics) from each step leads to smaller and smaller groups until the option is reduced to single and unique trait of an organism.
Considering you need to identify an organism. So, on the top of they key is animal with options: (a) with red blood cells and (b) no red blood cells. The option you will select is no red blood cells and under option b, you’re given two choices again: (a) hard bodies and (b) soft bodies. You’ll select soft bodies, then two options again are given: (a) with shell and (b) without shell. The option you’ll select would be without shell, and so on.
1. True.
2. Given: Mass = 30 Kg
Acceleration = 2.0m/s2
Force= mass x acceleration
Force= 30Kg x 2.0 m/s2
Force= 120 N
3. Given : Mass = 30 Kg
Force= 180 N
Force = Mass x Acceleration
Acceleration = Force / Mass
= 180 N / 30 Kg
Acceleration = 6.0 m/s2
