Organisms who happen to be best suited to an environment and reproduce most successfully will be consider successful in terms of natural selection.
1.What is the probability that a sperm from the father will contain the PKU allele?
Probability = ½
2.What is the probability that an egg from the mother will contain the PKU allele?
Probability = ½
3.What is the probability that their next child will have PKU?
Probability = ¼ (because each parent has ½ chance ½ X ½ = ¼)
4.What is the probability that their next child will be heterozygous for the PKU gene?
Probability = ½ (because each parent has ½ chance of donating the ‘P’ allele and ½ chance of donating the ‘p’ allele (½ x ½) + (½ x ½) = ½
Answer:
Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.
Explanation:
The greater the amount of active transport carried out by a cell, the greater the amount of mitochondria would be found in the cell.
Active transport uses energy. Mitochondria undergoes aerobic respiration to release large amounts of energy. If the cell is found to be lacking in energy needed for active transport, the cell would adapt by synthesizing more mitochondrion to ensure that it's demand of energy is met.
