The map shows the main streams and the rivers near City A and City B, as well as the nearby factories and farmland. The arrows i

n the diagram show the direction of the water flow. City A gets its water from the sunset River and City B gets its water from the Moth Lake. A liquid herbicide was applied to a farmland. Based on the information in the map shown, which city would most likely have the best water quality and why? Choose the best answer.
Select one:

City A because there are no pollution sources upstream.

City B because it is fed by two rivers instead of just one.

City B because it is next to a lake which would have more clean water available.

City A because it is farther North which means it is colder so the water is cleaner.

Answer:

A. City A because there are no pollution sources upstream.

Explanation:

Water pollution is th contamination of water. There are many means through which water is contaminated such as industrial waste, agricultural waste and domestic waste et-cetra.

City A and City B get water from sunset lake and moth lake which have factories (industrial waste) and farmland (agricultural waste) nearby them, which are responsible for the contamination of river water. due to this cities can recieve contaminated water which can affect their health.

But the quality of water in City A will be best than that of City B because according to the image, City A do not have nay upstream soooooource of pollution, as factories and farmland are located at downstream.

Hence, the correct option is A.

genetics book g how do you know that only a single gene is responsible for he color diferences between these snakes?
mariarad [96]

Answer:

Here is the full question:

An albino corn snake is crossed with a normal colored corn snake. The offspring are all normal-colored. When the first generation progeny snakes are crossed among themselves, they produce 32 normal colored snakes and 10 albino snakes.

a. How do you know that only a single gene is responsible for the color differences between these snakes?

b. which of these phenotypes is controlled by the dominant allele?

c. a normal colored female snake is involved in a test cross. This cross produces 10 normal colored and 11 albina offspring. what are the genotypes of the parents?

Explanation:

First of all, in genetics, Phenotype are the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype can be determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences on these genes.

Allele, which can also be called allelomorph, is any one of two or more genes that may occur alternatively at a given site on a chromosome. Alleles may occur in pairs, or we may have multiple alleles affecting the phenotype of a particular trait. The combination of alleles that an organism carries is its genotype. If the paired alleles are the same, the organism’s genotype is said to be homozygous for that trait. If they are different, the organism’s genotype is heterozygous. A dominant allele (A) will override the traits of a recessive allele (a) in a heterozygous pairing.

(a) In the question, we have two phenotypes seen in the second generation of this cross: normal and albino. Therefore, only one gene with two alleles is needed to control the phenotypes like colour of the snakes observed. The 3:1 ratio of these phenotypes in the F2 generation will be seen only if a single gene is involved.

(b) The allele controlling the normal phenotype (A) is dominant to the allele controlling the albino phenotype (a).

(c) The male parent’s genotype is aa. The normally colored offspring must receive an A allele from the mother, so the genotype of the normal offspring of the testcross is Aa. The albino offspring must receive an a allele from the mother, so the genotype of the albino offspring of the testcross is aa. Thus, the female parent must be heterozygous Aa.

This would be Mitosis.

Mitosis results in two diploid cells.

Meiosis, on the other hand, results in four haploid cells.

inysia [295]

Answer:

Biodiversity: Tropical rainforests are areas of extremely high biodiversity compared to other ecosystems. Biologists estimate that tropical rainforests contain about 50% of the world's terrestrial plant and animal species, yet they encompass only about 6% of the world's land area.
