Answer:
1. Polygenic
2. RW
Explanation:
1. A polygenic trait is regulated by more than one gene. The phenotype of the organism is regulated by sum total of all the dominant alleles of these genes. Therefore, these traits exhibit continuous variations and are called quantitative traits. Skin color in humans is an example as it is regulated by more than one genes and the phenotype is determined by total dominant alleles of these genes.
2. If allele R gives red phenotype and the W gives white phenotype, a cross between RR (red) and WW (white) would produce all the cows with RW genotype. The parent cow with RR genotype would form all the gametes with R allele while all the gametes from WW parent would have one copy of the W allele. The random fusion of gametes with R and W alleles would produce progeny with RW genotype.
The answer should be an aloe plant
Answer: The correct answer is -
D) A ---> B + C + energy.
Explanation:
Catabolic reactions can be described as one of the two types of metabolic reaction (other being anabolic) which occur within cell when complex organic molecules are broken down to form simpler, smaller molecules.
For example - Respiration, which involves glucose breakdown in order to form carbon dioxide and water. Generally they are type of hydrolysis reactions, which include water to break bonds present in complex molecules.
Large amount of energy is also released during these reactions.
Thus, option D) shows catabolic reaction.
Answer:
Mouth is the first portion of the alimentary canal that receives food and produces saliva.
It depends. It could be 2 am and 14:00 pm if it's on a mechanical clock
