DNA is made up of pairs of nitrogenous bases. Which of the following
nitrogenous bases is paired correctly?
A. Guanine-guanine
B. Adenine-thymine
C. Adenine-guanine
D. Cytosine-thymine
DNA is made up of pairs of nitrogenous bases. The nitrogenous bases is paired correctly is Adenine-thymine. Thus, option B is correct.
How DNA is made up off?The DNA is formed by the nitrogen bases adenine, cytosine, guanine and thymine. The pairings between bases are -Adenine with Thymine and Cytosine with guanine. Nitrogenous bases are heterocyclic, planar, and relatively water-insoluble aromatic molecules.DNA consist of two types of nitrogenous bases-Purines and Pyrimidines.
Purines are the two common purine bases found in DNA are Guanine and Adenine. Pyrimidine-The two common pyrimidine bases found in DNA are Thymine and Cytosine.
According to the base-pairing rule in DNA- Adenine (purine) pairs with Thymine (Pyrimidine) and Guanine (purine) pairs with Cytosine. Adenine pairs with Thymine with two hydrogen bonds and Guanine pairs with Cytosine with three hydrogen bonds.
Thus, option B is correct.

A sea otter is critical to the functioning of the ecosystem in which it lives. It affects the
survival and abundance of many other species in its community. It is a(n) species.
Answer: A keystone species.
A sea otter is critical to the functioning of the ecosystem in which it lives. It affects the survival and abundance of many species because it is a keystone species. Option a is the correct answer.
What is an ecosystem?Living and nonliving organisms coexist in an ecosystem. Living are called "biotic" factors, while non-living are called "abiotic." Different ecosystems have different biotic organisms, such as animals and plants. In some ecosystems, a particular species has more importance. They are called keystone species.
This species is key to the functioning of the ecosystem. Without the keystone species, the ecosystem would not function well. The statement's example is the role of the sea otter.
Some species are found in abundance in some ecosystem. If they are hunted for their resources, their numbers will decline. This type of species is called an endangered species.
Hence, the sea otter is a keystone species. It maintains the survival of many other species in the ecosystem. Option a is correct.

Evaluate whether two places at the same altitude would have the same climate.
Answer:
Places at the same latitude may have very different climates if one is on a coast and one is inland. On the coast, the climate is influenced by warm moist air from the ocean. Farther inland, the climate is influenced by cold or hot air from the land. So, it depends on where you are on the world.
why terrace farming is advantageous in hilly and mountains

In rabbits, black fur (B) is dominant to white fur (b). A purebred black furred male is bred with a female that had the recessive white fur
Answer:
All the offsprings will be black-furred (Bb)
Explanation:
This question involves a single gene coding for fur length in rabbits. The allele for black fur (B) is dominant to the allele for white fur (b). This means that a rabbit heterozygous for this gene (Bb) will have a black fur.
According to this question, a purebred black furred male (BB) is bred with a female that had the recessive white fur (bb). The parents will produce gametes as follows:
BB - B only
bb - b only
Using these gametes in a punnet square (see attached image), the genotypic proportion of the produced offsprings is as follows:
Bb, Bb, Bb, Bb
All Bb (heterozygous) means that all of the offsprings will be black-furred.
