Answer:

The correct answer is option D, Unconfined aquifers​ are found between two layers of impermeable soil or rock.

Explanation:

An unconfined aquifer is not confined by rock layer on both of its side. Usually the ground water level (GWL) is considered as the upper layer of unconfined aquifer. Also the rocky layer found on the other side of the unconfined aquifer is not impermeable as the major source of recharge of unconfined aquifer is the seepage of water through is permeable layer or through rain.

The field of inquiry that studies human culture and evolutionary aspects of human biology; includes cultural anthropology, arche
klio [65]

Answer:

physical, or biological anthropology.

Explanation:

When there is a need to study human kind   through the X-ray of  relationships between human biology, its cultural diversity, and  evolution ,the aspect anthropology for this is Biological anthropology.

Therefore biological anthropology is concerned about how the interaction between the cultural diversity and biological process results in the  adaptations of mankind to different  environments.The influence of these on growth, behaviours, existence.

The primary focus of biological anthropologists is to study in details the concept of  ,mechanism of  variation,  adaptation.and how these lead to evolution and origin of mankind.

Sequel to this ,most evidences for this concept are obtained from the study of fossil materials,study of other related primates to man, and components of functional biology and genetics.

Provide explanations of genotypes and phenotypes.
Korvikt [17]
The phenotype is the physical appearance of an organism, while the Genotype is the genetic composition of an organism. Phenotype is observable and are the expression of the genes of an individual. So even the organism with the same species may differ, with a minute difference in their genotype. This is the main difference between the two.

We can notice one’s hair colour, eye colour, height, weight, skin colour, etc. but cannot look at genes responsible for these characters, so the observable physical look is the phenotype while the unnoticed genes responsible for such characters present in the DNA of cell of the individual is genotype.

To explain the above lines, here is the simple example of a pure red colour flowering plant (RR) is crossed with the white colour flowering plant (rr). The result of the Genotype of the F1 generation will be – Rr (Hybrid red colour), and the Phenotype of the F1 generation will be the – Red colour flowering plant.

Genotype and phenotype are the two very closely related and similar-sounding words, but their meaning is different. Our earth has a dynamic variety of organisms, present in soil, water and on land. But as the genome of each organism is different, and so there phenotypes also whether it’s their colour, height, weight or other morphological features.

In the experiment determining the parental genotype of plant seedlings from a monohybrid cross, if the dominant color was green
eimsori [14]

Answer:

cc × cc

Explanation:

This question involves a single gene coding for plant seedling. The green allele (C) is dominant over the white allele (c). This means that the green allele will mask the phenotypic expression of the white allele in a heterozygous state (Cc).

In this experiment where plate 1 only contained white seedlings instead of all green, this illustrates that all the offsprings were recessive. This is because the parental genotypes were both recessive for the color trait i.e. cc.

Note that, the recessive trait can only be expressed when the recessive alleles are present in a gene. Therefore, the parental genotype would have been cc × cc, in order to give rise to all offsprings with the recessive trait (white colour).
