The term 2pq represented in the hardy-weinberg equation is the frequency of heterozygotes and is denoted as option D.
<h3>What is Hardy-weinberg equation?</h3>
This mathematical equation is used to calculate the genetic variation of a population at equilibrium and can be seen below:
p² + 2pq + q² = 1
where
p² is dominant homozygous frequency (AA)
2pq is heterozygous frequency (Aa)
q² is recessive homozygous frequency (aa).
The 2pq can be seen as the heterozygous frequency which is therefore the reason why option D which is frequency of heterozygotes was chosen as the most appropriate choice.

Answer: Monoamine oxidase inhibitors will elevate the concentration of norepinephrine in the synapse.
Explanation: Monoamine oxidase is an enzyme that catalyzes the removal of monoamines such as norepinephrine, serotonin and dopamine from the brain. Monoamines are neurotransmitters involved in the transmission of nerve impulses in the brain. Monoamine oxidase inhibitors prevent the removal of these neurotransmitters thereby making them more available in the synapse. MAOIs inhibit the action of monoamine oxidase which catalyzes the removal of norepinephrine from the synapse thereby raising the level of norepinephrine in the synapse.
Urbanization increases local greenhouse gases hence the local greenhouse effect increases the temperatures of the region. This way, the balance of land and aquatic ecosystems are upset. Different species populations may be affected differently.
All the concrete and tarmac on ground reduces the percolation rate of water in the soil and increases runoffs. This results to a lower the water table and increases erosion.
Urbanization leads to clearing of land and draining of wetlands for structures, This destroyed the habitat of species in the process hence displacing organisms.
Answer:
Our major catfish species spawn during spring or summer when the water warms to an optimal temperature. Channel and blue catfish spawn at 70-84 degrees, but 80-81 degrees is considered best. Flatheads spawn at 66-75 degrees. Catfish spawning begins at different times in different latitudes, progressing from south to north.
