Answer:
Number of babies with dominant hemoglobin genotype will be 
Explanation:
Given -
% of babies have SCD which means they have recessive version of hemoglobin
Let the recessive version of hemoglobin be represented by "h" and normal version of hemoglobin be represented by "H"
Babies having SCD will have genotype "hh" i.e homozygous recessive.
As per Hardy Weinberg's equation -
Thus, frequency of allele for recessive version of hemoglobin (h) is
Frequency of allele for normal version of hemoglobin (H) is
Thus, Frequency of population with normal version of hemoglobin i.e HH is equal to
hence, number of babies with dominant hemoglobin genotype will be
Answer: The action of a neurotransmitter at the postsynaptic cell is terminated by the following: enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.
Explanation: After a neurotransmitter has bound to its receptor on the postsynaptic membrane and triggered a biological response, in order to avoid over stimulation of the receptors, the neurotransmitter is either degraded by specific enzymes or taken back to the presynaptic cell into the synaptic vesicles by action of specific transporters. This mechanism is to maintain a balance (homeostasis).
The reactive CARBONYL GROUP, contributes to the ability of aldehydes and ketones to be involved in energy reactions. Aldehydes and ketones undergo different types of reactions that lead to various products. One example of these reactions are nucloephilic reactions which lead to the production of alcohols, alkenes, diols, imine, etc.
Answer:
The first one is false because Neurotransmitters are located in a part of the neuron called the axon terminal.

Answer:
Humans directly change the dynamics of the water cycle through dams constructed for water storage, and through water withdrawals for industrial, agricultural, or domestic purposes. Climate change is expected to additionally affect water supply and demand.
Fossil fuel production is another human activity that places considerable strain on drinking water — and not just because fracking and coal mining use a great deal of water, but because their waste products can pollute groundwater, and therefore drinking water, as well.Water resources face a host of serious threats, all caused primarily by human activity. They include pollution, climate change, urban growth, and landscape changes such as deforestation. Each of them has its own specific impact, usually directly on ecosystems and in turn on water resources.
