<span>Genetic variation can be caused by mutation (which can
create entirely new alleles in a population), random mating, random
fertilization, and recombination between homologous chromosomes during
meiosis (which reshuffles alleles within an organism's offspring)</span>
Answer:
Factors that remain constant from experiment to experiment are the constants.
Explanation:
A constant in an experiment is also known as a <em>control variable</em>. It is the part of an experiment that must stay the same in order to validate the experiment. If the constant were to change, the results would be skewed and therefore false.
i.e. you want to test the rate of growth of lima bean plants in different types of lighting. You believe that a lima bean plant that grows in yellow will grow faster and stronger than a lima bean plant that grows in blue or red light.
In this experiment, the constant would be the lima bean plant. You cannot change the type of seed or else your experiment is invalidated. If you tried to use a sunflower seed in the blue lighting and a tomato seed in the red lighting, your results would be invalidated and skewed.
It is 0%. They only have the recessive alleles (ss) so there is no possibility it can ever produce a gamete with a dominant allele (S). For example, if it was Ss it would be 50%, and for SS it would be 100%.
Answer:
A
Explanation
Example glucose on glycolysis yield water,ATP and pyruvate.Pyruvate is then converted to acetyl COA which enter to the Krebs cycle to produce carbon dioxide and more energy rich molecules
Answer:
Cube with length 4cm.
Explanation:
The surface area of cube is 6a^2.
For cube with length 3
A= 6a^2
A= 6 ×(3×3)
=6(9)
= 54cm
For cube b.
A=6(a^2)
= 6×(4×4)
6(16)
= 96cm
