Answer:
Hereditary traits.
Explanation:
Since these two parrots (with two different parents), one with yellow feathers and the other one red, it would make sense that they inherited their traits from their parents.
Just as humans have different colors of hair. Parrots can have different chest colors. Both of these come from hereditary genes.
Answer:
Answer is sigma.
Explanation:
The sigma factor can be described as protein regulating transcription in bacteria. That is, it enables the synthesis of RNA at specific locations in DNA. This specific location is known as promoters.
The sigma factor is also known as specificity factor, because, it is specific for the gene.
Transcription can be explained as the process by which genetic information in the DNA strained are copied into a new molecule of mRNA, through the aid of RNA polymerase.
It should be noted that, when there is an increase in pressure, at constant temperature, the stability of elongation complex will decrease. This means that, temperature determines the pressure at which transcription elongation stops.
In a situation where the concentration of solute is low inside the cell, the cell will be referred to as a hypotonic cell. The transport in this type is referred to as active transport.
<h3>What is active transport?</h3>
The movement of dissolved molecules into or out of a cell via the cell membrane, from a low concentration region to a high concentration region is referred to as active transport.
These particles use the energy released during respiration to move against the concentration gradient.
Thus, in a situation where the concentration of solute is low inside the cell, the cell will be referred to as a hypotonic cell. The transport in this type is referred to as active transport.

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.
Prokaryotic bacteria are surrounded by a cell membrane that contains the transport proteins to regulate the entry and exit of materials through the cell, the cell wall to help maintain cell shape and structure, and the capsule, which aids against drying out and protects bacteria from a host's immune system.
<h3><u>Explanation:</u></h3>
Bacteria are the prokaryotic organisms that are found in every part of Earth. These organisms do have an interesting ultrastructure. The coverings of the bacteria are three in layer. They are
A. The outer capsule.
B. The middle cell wall.
C. The inner cell membrane.
The capsule is the outermost covering of bacteria that is formed of different slimy materials. These materials contains hygroscopic substances which can absorb water from the surroundings even when the water concentration in outside is very very low. This layer of protection outside bacteria help them to protect themselves against drying out at dry conditions.
The middle cell wall is formed of polymers of N acetyl glucosamine and N acetyl muramic acid. This layer is chitin in nature and is strong enough to maintain the shape and size of bacteria irrespective of outer conditions.
The innermost layer of bacteria is cell membrane which is formed of proteins and lipids bilayer and this cell membrane contains different transport for proteins which help in transport of different substances like water and nutrients inside the cell by means of active transport or passive diffusion.
