Hi Geny!

Question - Describe the cell theory and the developments that led to the cell theory.

Answer:

There are 3 main components of cell theory:

  1. Each and every organism is wither unicellular or multicellular.
  2. The basic unit of life is the cell.
  3. Cells are created from cells that had existed previously.

There were 3 scientists that made cell theory each of the 3 components of above were the 3 scientists.

  1. Mathia Schleiden discovered that plants were made of mainly cells.
  2. Rudolf Virchow discovered that cells are created from calls that had existed previously.
  3. Theodore Schwann discovered that animals were also made of mainly cells.

Hope This Helps :)

In the marine mollusk, Aplysia, serotonin binds to a G-protein-coupled receptor and activates a Gs subunit. The resulting activa
dem82 [27]

The serotonin binds to a G-protein -coupled receptor and activates a G-subunit . This results in activation of PKA and closing of the potassium channels. This will subsequently decrease the influx of potassium ions into the cell, and lead to depolarization of the cell. This changes the membrane potential of the cell.

Aplysia are sea slugs which fall under the category of mollusks. Serotonin is a hormone which is responsible for the transfer of electrical signals from the brain to different parts. In this particular mollusk, serotonin was studied to find that it is an essential neurotransmitter that is responsible for the maintenance of synaptic plasticity in the neurons. Synaptic plasticity is the feature which is essential for the communication of neurons. This is the modification which occurs at the synapses during the transmission of synapses. Without this activity, the transmission of signals would be impossible.

Homozygotes with two sickle-cell alleles are selected against because of mortality. However, heterozygotes for sickle-cell allel
grigory [225]

Answer:

Increased frequency of the allele for sickle cell anemia

Explanation:

Sickle cell anemia is fatal in homozygous genotype. The homozygous genotype having two copies of the allele for sickle cell anemia is not favored by natural selection due to its reduced survival success.

However, the heterozygous genotype for sickle cell anemia with one allele for the disease exhibit malaria resistant. The presence of one allele is not fatal for the organisms as the presence of one normal allele ensures the formation of some normal hemoglobin protein and RBCs to support the oxygen delivery to the body parts.

The increased survival success of heterozygous genotype in malaria-prone regions allowed their natural selection. This increased the frequency of allele for the sickle cell anemia in the gene pool of the local population and increased the frequency of heterozygous dominant genotype.
