C. Condensation and Evaporation are the two ways in which energy is transferred between layers of the atmosphere.
Agonists activate the receptor thereby <u>increasing</u> activity at the synapse while antagonists generally prevent agonists from activating the receptors thereby <u>decreasing</u> activity at the synapse.
- An agonist is the component that has the ability to increase the activity carried out by another substance.
- The agonists work from their faculty of coupling to a cell-type receptor, in this way, they manage to generate a certain action in the cell.
- The antagonists are the compounds that cause the opposite when they bind to the receptor, they cause a blockade by decreasing the activation of a synaptic receptor.
Therefore, we can conclude that agonists are compounds capable of increasing the action of synapse and blockers (antagonists) decrease activity at the synapse.

Endocrine gland functions with your hormones. Exocrine gland deals with waste and getting rid of it. Which both of them don’t deal with digestion.
Phenotypes are the physical characteristics that result from the genotype, which is the genetic makeup of the organism. In this case, either straight hairline or Widow's peak will be the phenotype, as they are the physical characteristics being discussed.
The questions states that a Widow's peak is dominant over straight hairline. So we are going to assume that the Widow's peak allele is W (dominant), and the straight hairline allele is w (recessive).
A dominant allele will mask the presence of a recessive allele unless both of the alleles are both recessive (both ww).
So for the WW genotype, we are going to see the dominant phenotype: Widow's peak.
For the Ww genotype, we are also going to see the dominant phenotype since the dominant allele is going to mask the presence of the recessive allele, so we are going to see: Widow's peak.
Lastly, for the ww genotype, we are going to now see the recessive phenotype, since both alleles are recessive: straight hairline. Note that their are two of these type of offspring as stated in the question.
