Answer:
I don't know the correct answer for this (cus I'm in year 10)
Explanation:
But in this case, answer C would be definitely wrong becuase answer C is talking about protocell and it not related much to what the question is asking. Hope this can help you find out more about the other 3 answers.
Deforestation leads to fewer plants being available to conduct photosynthesis. Less oxygen is available for cellular respiration is a possible effect on the remaining plant populations.
<u>Explanation:</u>
- Deforestation and Photosynthesis are related to each other. Because if Deforestation occurs more photosynthesis will reduce.
- Cutting and burning down of the trees causes deforestation as it affects photosynthesis. Plants prepare food using photosynthesis.
- The plant takes carbon-di-oxide for the preparation of food and releases oxygen. Oxygen is required for every living thing in the world.
- As now World goes on deforestation and it should be seriously stopped.
1)Chargaff's rules state that DNA from any cell of any organisms should have a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.
2)DNA structure
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
3)A nucleotide consists of three things: A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil). A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons. One or more phosphate groups.
4)DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.
5)The diagram has show in above.
6)complementary base pairing is necessary because the double helix shape would not be the same if not. Doubles would only pair with doubles and the singles to singles.

Answer: continental glacier
Explanation:
These glaciers are very big and they can cover large amounts of land. These can also cover very large islands. Continental glaciers are the answer.
