The answer is A because they need the sunlight to go through the water
Answer: B
Explanation: And why are you searching up the answers if thats a MapTest -_-
First things first, I'd call this a questionnaire rather than a problem but anyways. Your DNA profile is literally your identity, and to have that stored in the medical records would be useful in some other cases besides medical issues. It is like having a copy of your fingerprint in the government's hands. Thus one may find it useful as another way to identify someone when the need occurs. As for purposes such as to be referred for the development of personal medical treatment (I believe you're referring to project CRISPR) , is not as necessary because the way they identify mutated genes or "infected" DNA or cells is by referring it to the normal DNA found in any other cells in your body, and if cells are that easy to access, they do not have the need to keep a medical record just for your DNA sequence along with all your gene codes, especially when you are performing investigations on the same species, humans, who have the same number of chromosomes with the similar genes.
Answer:
The polarity of water molecules means that molecules of water will stick to each other. This is called hydrogen bonding. Polarity makes water a good solvent, gives it the ability to stick to itself (cohesion), stick to other substances (adhesion), and have surface tension (due to hydrogen bonding).
Explanation:
4 different phenotypes may be produced. If you write this down in a Punnet square you can get the exact ratio and the genotypes along with the phenotypes.
Let us assign B for brown eyes, b for blue eyes; H for right-handed, h for left-handed.
The mother's genotype will then be bbhh
The father's genotype will then be BbHh
bh bh bh bh
BH BbHh BbHh BbHh BbHh
Bh Bbhh Bbhh Bbhh Bbhh
bH bbHh bbHh bbHh bbHh
bh bbhh bbhh bbhh bbhh
Now based on that you can see that there are 4 possible genotypic combinations which would express different phenotypic combinations as well.
BbHh: Brown-eyed, right-handed
Bbhh: Brown-eyed, left-handed
bbHh: Blue-eyed, right handed
bbhh: Blue-eyed, left-handed
So again, there would be 4 possible phenotypes.
