Answer:
B. There will be two cells each with 36 chromosomes.
Explanation:
The products of mitosis are called diploid cells, and they each have the complete set of chromosomes. These cells are usually important for activities such as growth, repair etc. They make up our normal body (somatic) cells. Therefore, the answer is 36, only 36 matches the description of genetically identical cells
Aerobic because it produces up to 38 ATP versus anaerobic which only produces 2 ATP
Answer:
Im pretty sure that "Refining oil pollutes the air with nitrogen dioxide" is a true statement.
Explanation:
well,,, all the others are false because: groundwater is definitly part of the water cycle, most of earth's water is NOT fresh bc only 2% of earth's water is fresh, and hydroelectric power would contribute more to water pollution than to thermal pollution-

Answer:
Phenotypic ratio 1:1:1:1
Explanation:
A test cross is a cross between an individual with heterozygous genotype and a homozygous recessive individual, in order to ascertain the actual genotype of the dominant parent i.e whether homozygous or heterozygous.
In this case, which is a dihybrid cross involving two genes A and B. The allele A is dominant over allele a, since it masks the expression in a heterozygous state. The same applies for allele B and b.
Therefore, allele A and B are dominant alleles while allele a and b are recessive alleles.
In a cross between an heterozygous parent (AaBb) and a homozygous recessive (aabb), each individual will undergo meiosis and produce gametes. According to Mendel's law of independent assortment, the alleles of each individual get sorted into gametes independent of one another.
The four possible gametes produced by each parent are:
AaBb: AB, Ab, aB, ab
aabb: ab, ab, ab, ab
Thus, using a punnet square (see attached image), the possible 16 progenies will possess four different genotypes: AaBb (4), Aabb (4), aaBb(4), aabb(4)
Considering the four distinct genotypes, the phenotypes will also differ. Hence, the phenotypic ratio: 4:4:4:4 ~ 1:1:1:1
