The albedo is simply the ability of a surface to reflect the Sun light. It differs from one surface to another, with the more barren lands of the ones covered with ice being able to reflect more Sun light, while the ones that are covered with dense vegetation reflecting less.
The prairies are covered with grasses, so they are kind of in between the ones that reflect more and less. While the grasses manage to reflect part of the sunlight and not allow to get to the ground, because they are short and there's spaces between them, still part of the Sun light manages to get to the ground.
To compare it with the tundra biome, the prairie reflects much less. The reason for that is that the tundra is covered with ice for most of the year. The ice had very light coloration, and the light colors have much higher albedo. The ice manages to reflect most of the Sun light, which i turn causes less heating on the surface, and the ice expands even more.
Answer:
A(the first one)
Explanation:
Homeostasis maintains the constant internal conditions in an organism. It is important because cells function best with a limited range of conditions. ... All living things have body parts with different functions that help them survive.
Answer:
DNA fingerprinting is a method used to identify living things based on samples of their DNA. Instead of looking at the whole sequence of a person’s DNA, these techniques look at the presence or absence of common markers that can be quickly and easily identified. DNA Fingerprinting Explained

Answer:
Option (a), (c), and (d).
Explanation:
The DNA is the genetic material of almost all the living organisms but in case of some viruses RNA acts as the genetic material. The DNA requires the binding of proteins and factors for the proper functioning of the cellular system.
The DNA and protein interaction is bounded by non covalent interactions as these interactions are not permanent in nature. The non covalent interaction include the hydrogen bonding, vander walls and ionic interaction. The covalent interaction is the strongest interaction present in nature.
Thus, the correct answer is option (f).
Answer:
The final product is four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.
Explanation:
If nondisjunction occurs during meiosis 1, a pair of homologous chromosomes fail to separate, and one of the daughter cells will have the two chromosomes while the other cell will not get any chromosome from the pair.
If meiosis 1 occurs normally, but nondisjunction occurs in meiosis 2, sister chromatids fail to separate.
The usual process of meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.
If the diploid number of the original cell is 8 (2n=8), then under normal conditions, each haploid daughter cell should have 4 chromosomes (n = 4).
But in the exposed example, one pair of homologous chromosomes experiences nondisjunction during meiosis I (in the attached file, you will recognize this pair as the red one). The other chromosomes separate as usual. So one of the daughter cells will have one extra chromosome than expected (five instead of four), and the other daughter cell will lack one chromosome (three instead of four). Meiosis II occurs normally. The final result is the formation of four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.
