In the soil profile, the remains of plants and animals are present in a layer known as the humus layer. The topsoil or the A horizon refers to a zone of leaching and the habitat of various species. The subsoil or the B horizon refers to a zone where the organic matter and soluble salts are leached from the A horizon is accumulated.

The weathered part of the rock, which produces the parent substance over which a soil establishes makes the C horizon, and the unweathered part of the parent substance forms the D horizon. Thus, from the given diagram it is clear that the layer Y comprises unweathered part of the parent material.

omeli [17]

Answer:

C. Organism living in the fallen trees lose shelter.

Explanation:

talking about the effects of storm winds falling trees, it creates more light to reach shorter plant which will help the plants to do photosynthesis well, which will even facilitate their fast growth; that's positive.

Fallen trees becoming food for decomposers can also be positive cause this will help the soil or earth of that forest have fertility

New Clearing attracting animals such as man can lead to extinction of forest which to conservators they feel like no-no-no-no that's they'd see it as a negative consequence of the wind storm effect, yes this can lead to de-sheltering of organisms inhabiting that niche(trees)

Human ABO blood type is controlled by the I locus and has three possible alleles. The alleles which code for type A blood (IA) a

Oxana [17]

Answer:

1/8 (12.5 %)

Explanation:

Cross: IAi X IAIB

F1: 1/4 IAIA 1/4 IAIB 1/4 IAi 1/4 IBi

Phenotypes:

- IAIA and IAi >> type A blood

- IBi >> type B blood

- IAIB >> type AB blood

Phenotypic frequency type A blood: 1/2 (i.e., 1/4 IAIA + 1/4 IAi) >>

Probability to have 3 offspring with type A blood: 1/2 x 1/2 x 1/2 = 1/8

The human ABO blood group is a system consisting of there different alleles: A, B, and O. This system is used in genetics as an example of codominance because both A and B alleles are expressed in heterozygous individuals (i.e., IAIB), whereas only the allele A is expressed in individuals that have A and O alleles (since O allele is recessive to the A and B alleles).
