Answer:
Within double-stranded DNA, the nitrogenous bases on one strand pair with complementary bases along the other strand; in particular, A always pairs with T, and C always pairs with G. Then, during DNA replication, the two strands in the double helix separate.
Explanation:
The four nitrogenous bases of DNA are thymine, adenine, guanine, and cytosine. Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.
The most of the metabolic activity in the cell occur in the cytoplasm
Answer:
climate, geology, abstraction, poverty
Explanation:
Climate: lack of precipitation can lead to a lack of water. That is why is rain is important.
Geology can also be a factor in the availability of water. When water goes under the ground, rocks let the water enter through and make a water depot that is saved underground.
Regular cleaning of the water. Even though in some places there is enough water because of the pollution, it can’t be used.
Abstraction: it is important to have a limit when using water. If the amount of water for use is smaller than the water we get through precipitation, the quantity will be balanced.
When the country is rich, it can provide regular water inspection, while in poor countries this can be a big problem.
Answer: The reproductive capacity of the star fish is asexual.
Explanation: The starfish is known to reproduce another of its kind by fragmenting. It is by breaking a part of its one or more arms. The broken fragment grows to be individual starfish. And if you are wondering the broken arm of the parent starfish, well it regrows.
You can observe this phenomenon in plants as well and definitely with other sea creatures and bacteria, e.g., corals, sponges, and cyanobacteria
