Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.
Answer:
In mathematics it is used for dividing a number, whereas in science it is element which helps in proving certain effects. So they are different for different subject.
Explanation:
In mathematics factor is to break or divide in to numbers which can be further multiplied to get the actual number. Example 6 = 3 
2. here 2 and 3 are factors of 6. But when it comes to science factors are the elements that contributes something to result. It may be in controlled environment or naturally occurring one. The lab experiments are basically done in the controlled environment to check the factor effect over the experiment.
The first one is C. Varying in shapes of forelimbs
The second one is B. Enable members of a phylum to survive and reproduce.
The third one is B. Deuterostome development
35 grasshoppers/10 square meters has the highest population density.
- The highest population density of grasshoppers is 35 grasshoppers/10 square meters because more number of organisms are present in less area as compared to other population density.
- In the option i.e. 40 grasshoppers/20 square meters and 50 grasshoppers/30 square meters have more number of organisms but the area is also greater.
- And we know that high population density means more number of organisms in less area so we can conclude that 35 grasshoppers/10 square meters has the highest population density.

I’m pretty sure it is B. Please double check answers tho. It’s been a while since I learned adaptations. Also, if u go to my profile, it says I am 43. I am not a 43 year old middle schooler lol
