A 2016 experiment by researchers at UC Irvine established a link between autonomic nervous system activity during sleep and memo

ry consolidation. Participants in the study were given Remote Associates Test (a creative word association test) which was followed by the treatment: either a nap or quiet wake time. Following the treatment, a second Remote Associates Test. Individuals who napped showed improved performance on the second test compared to those who did not. The researchers found that heart rate variability and time spent in each sleep stage accounted for 73% of the improvement observed.
Regarding the experiment, which of the following is essential for consolidating the creative word test memories?
A. Brainstem
B. Cervical spinal cord segments
C. Thoracic spinal cord segments
D. Lumbar spinal cord segments

Answer:

A. Brainstem

Explanation:

Looking at the options, the correct one is Brainstem because it is the only one that deals with breathing, heart rate and blood pressure which definitely is linked to autonomic nervous system activity during sleep and the memory consolidation.

———— creates the skin-like surface formed due to the polar nature of water??
Cerrena [4.2K]

Answer:

Cohesion is the correct answer

Explanation:

Water molecules are held together by hydrogen bonds. Water molecules stick to other water molecules. Surface Tension. Creates the skin-like surface formed due to the polar nature of water.

Water is sticky because of hydrogen bonds. Water has a remarkable capacity to hold to itself and other objects. The capacity of water molecules to be attracted to other water molecules, allowing water to be a "sticky" liquid, is described by the Characteristic of cohesion.

A cell has a defect in its receptor for growth factors, preventing growth factors from attaching to and signalling the cell. Bas
morpeh [17]

Answer:

Option B

Explanation:

B. The cell will grow uncontrollably and continue to divide as long as it has food.

Cell growth is theeoretically stimulated by the binding of growth factors to their receptors using signaling pathways.

These pathways are regulated by proteins which are encoded for in the genes.

The gene that controls the regulation of these pathway when mutated produce malfunctioning signaling protein thus not allow for regulations of the cell cycle causing uncontrollable cell division. These mutated genes are called oncogenes.

The information in the table shows the possible genotypes resulting from the mating of two heterozygotes aadd. the allele a code
tensa zangetsu [6.8K]
Admitting that the "a" is a capital A for normal pigmentation and "d" is a capital D for dimpled chin, meaning that these are the dominant traits, the fraction expected to be albino with a non-dimpled chin is of 1/16.
When two heterozygous are crossed and two characteristics are being analysed, the offspring quantity that will possess the two recessive traits can be represented by 1/16. This is easily confirmed when a Punnett square is made. Considering that both parents were heterozygous, on both sides of the crossing in the Punnett square, you would have the following alleles' combination: AD, Ad, aD, and ad. The offspring that would be homozygous recessive (aadd) would correspond to only 1/16.
