Explanation:
1. If the man is homozygous recessive, it means it carries two identical, recessive alleles. During meiosis, the alleles will be split, and each sperm cell will have 1 t (recessive) allele.
2. During the separation in Anaphase II, both combinations of BB and bb will be possible.

Answer:
The exception is d) Inactivation of phosphodiesterase
Explanation:
In the presence of light:
a) The membrane potential of the photoreceptors is hyperpolarized, causing a reduction in the amount of neurotransmitter released by the photoreceptor terminal to the postsynaptic neurons
b) Sodium ions accumulate outside the plasma membrane and the receptor potential takes a form
of hyperpolarization 6. This change in membrane potential leads to the closure of calcium channels. The end result is a decrease in the secretion of the neurotransmitter glutamate by the photoreceptors
c) Visual transduction or phototransduction is the process by which a light photon generates a nervous response in the photoreceptors
d) As a consequence of phosphodiesterase activation, degradation of a molecule called cGMP (guanosine cyclic monophosphate) is stimulated
The main difference is that quotas restrict quantity while tariff works through prices
