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.

As per I know there is no scenario which describes fungi as a decomposer.

Algae are not plants, animals or fungi. They belong to Kingdom Protista, a diverse group of single-celled eukaryotes.
Protists have their own kingdom because many species share some characteristics of plants, animals or fungi.
Algae belong to the group of plant-like protists.
They are autotrophs that fulfill the role of producer in ecosystems because they make their own food via photosynthesis, like plants.

Answer: D) Tree roots improve soil water retention
There are many reasons which states that deforestation increases the risk of flood. First , some water stay on the leaves and evaporates in to the atmosphere. Second, tree leaves reduce the impact of raindrops on the soil which causes less soil erosion.
Third, tree roots absorb water from the soil, which make the soil dry and it absorb more water rainwater. The roots of tree hold the soil in place and reduce the movement of sediment which reduce the capacity of river to break its banking. Thus, reducing the chances of flood.
it is an organ. the main organ in the body. I wish your question was a little more clear, like multiple choice would be very helpful to what my choices are.

Sea otters tend to inhabit the shores of the pacific (sometimes rivers, ponds, or lakes), a favorite habitat is the kelp forests on the coast of California. Mother otters even tie their babies (and sometimes themselves) in kelp leaves, keeping them near and preventing floating away when diving for food. This is a clear sign of intelligence, and they classify as mammals. Otters stay in groups led by a dominant male, but sometimes females will leave with their babies, or males will depart in search of their own group to manage.
