Answer:
facilitated diffusion doesn't require energy, while active transport requires energy. Facilitaded difusion happens down the concentration gradient (molecules move from area of higher concentration to area of lower concentration), while active transports happens up the concentration gradient (from lower concentration to higher concentration).
Explanation:
False. Energy is only released when chemical bonds are formed.
Answer:
50%
Explanation:
According to the given information, the genotype of the mother who is homozygous recessive for gene "A" and homozygous dominant for gene "B"= "aaBB". Likewise, the genotype of the father who is heterozygous for gene "A" and homozygous recessive for gene "B"= "Aabb".
A cross between aaBB and Aabb would produce a progeny in following genotype ratio= 1/2 AaBb : 1/2 aaBb
Therefore, there are 50% chances for this couple to have a child heterozygous for both A and B genes (AaBb).
