Kelp attached to rocky substrate from dense forest help hide the otters from predators. Hope I could be of help to you! :)
1. The correct answer is: cell recognition protein
2. The correct answer is: The nonpolar tails are repelled by water, so they position themselves in the middle of the bilayer. The polar heads are attracted to water, so they point outward.
3. TRUE is As cell size decreases, the surface area-to-volume ratio increases.
4. The correct answer is: have no nucleus
have no membrane-bound organelles
The answer is true
I hope this helps

1. The answer depends on your picture.
DNA is packed and condensed with proteins in the form of chromosomes.
Since the process of division is going to start that means each chromosome will have an X shape. They had the DNA content copied once (in the S phase). The original, plus the copy created, form the X.
You just have to count the number of X's in the picture.
2. The answer is 4 nuclei.
Since the process of division happening is meiosis, that means that four new cells will be originated from a cell that's dividing.
So, four new cells each one with a nucleus, that means 4 nuclei in total.
If this was mitosis, only 2 new cells would be formed which means 2 nuclei
3. The number of chromosomes depends on your picture/exercise.
The answer would be half of the number of chromosomes that you started in the meiosis 1.
This time, chromosomes won't have an X shape since the copies were separated. At the end of the process, each chromosome has just one chromatid.
