What is fibrous root system?​
asambeis [7]

Answer:

Explanation:

The fibrous root is one of the small hair-like roots of the fibrous root system. Fibrous roots are derived from the base of the plant. This root system is available mainly in Monocotyledons, Gymnospermae (conifers) and Pteridophyta (ferns). Most of the fibrous roots grow horizontally and very few roots grow vertically to anchor the plant. Most importantly, the fibrous roots are short. They grow near the surface of the soil, not deep into the soil.

Luda [366]

Answer:

Parathyroid hormone increases the level of calcium while calcitonin hormone  decreases the level of calcium in the blood.

Parathyroid hormone is a type of harmone which is responsible for balancing calcium in our body. When the calcium level lowers in our body, parathyroid hormone is secreted and calcium is absorbed from the bones and fullfilled the requirement of the body. If the tumor secreted calcitonin hormone instead of parathyroid hormone, the calcium level in the blood is lowered because it acts to the opposite of parathyroid hormone.

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).
