It too does Not require cellular energy. When molecules cannot move through a cell membrane passively, the Cell uses a process called_____________. This process uses_______________ found in the cells Membrane to pass particles and reach equilibrium.
Option A is correct. After making a punnet square, we can see that the genotypic ratio would be 1:2:1, being 25% dominant, 25% recessive and 50% heterozygous. However, we are asked for the phenotypic trait percentage. The phenotypic ration is 3:1, with 75% polka dotted tail (dominant gene active) and 25% solid tail (recessive gene active).
Pls thanks + branliest :P
The observable traits expressed by an organism are referred to as its phenotype. An organism's underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype.
Answer:
The correct answer is d the positive feed back reduces change in the the system
Explanation:
In an biochemical reaction when the released product stimulate the release and activation of the same product and act together to exibit their biological function, then this type of regulation is called positive feedback.
The positive feed back mechanism leads to increased change in the system that"s why it is named so.
For example during blood clotting platelets molecules are released to form clots to stop bleeding. one activated platelet can stimulates the activity of other platelets which then join together to form a group for generating further blood clots.
