Answer:
a. Genotype of the parents are; Rr and rr
b. Please find the explanation to A below
Explanation:
This question involves a single gene that codes for flower color in a plant. The allele for red flower (R) is dominant over the allele for white flower (r). This means that a plant that is heterozygous for flower color (Rr) will be red.
In a cross between a plant with red flowers and white flowers, the phenotype of the offsprings is represented as: 37 plants with red flowers and 41 plants with white flowers. Observing from this number, one would realize that the phenotype ratio is equivalent to 1:1. This phenotypic ratio is only possible when the parent with red flower is heterozygous for the gene i.e. Rr. Hence, the genotype of the parents are: Rr and rr.
b) If one were to cross Rr (red flower) × rr (white flower), the phenotypic ratio of red to white offsprings will be 1:1. Hence, judging from the ratio got from the cross of the two parents above (1:1), the parental genotypes are Rr and rr.
Secondary active transport protein link the transport of an ion downward its gradient with the transport of another particle against its gradient, whereas primary active carrier proteins move both components in the opposite direction of their respective gradients.
<h3>Which proteins are essential for active transport?</h3>
Instead of channel proteins, carrier proteins are used in active transport. Since these carrier proteins require ATP to change shape, they differ from those seen in facilitated diffusion.
<h3>Why do proteins play a part in active transport?</h3>
- Specialized carrier proteins are needed for active transport, and cellular energy must be used.
- When a chemical's phospholipid bilayer is impermeable to it or when there is a concentration gradient, carrier proteins allow chemicals to pass through the membrane.
<h3>What kinds of proteins are carriers?</h3>
The carrier proteins can be categorized as being driven by ATP, electrochemical potential, or light, depending on the source of energy.

Answer:
Seasons are caused by the Earth's auxiliary tilt. As the Earth revolves around the sun the tilt causes the Northern ans Southern hemispheres to trade places.
