Answer:

Option E, C tactile (CT) afferent

Explanation:

Whenever a slow moving gentle touch experienced, the response is due to the nerve fibers called C-Tactile afferents (CTs).  

C-Tactile afferents (CTs) are unmyelinated mechanoreceptors  of low threshold and low conduction velocities.  

In humans, CT neurons are found in hairy skin.  

The pleasant feeling observed during a slow gentle touch is due to the interaction of  

CT neurons project to the insular cortex in the brain

Hence, option E is correct

Had these chromosomes undergone replication before they were separated
lina2011 [118]
The longitudinal halves of a chromosome that has undergone replication are known as chromatids.  They will not be called chromosomes until after they are separated during Mitosis.  Mitosis distribute the chromatids to daughter cells as a cell divides.  The chromosomes are initially replicated in cells undergoing Meiosis, as in preparation for the mitotic division, but then, these chromosomes are divided twice so that four daughter nuclei are produced, each having the haploid chromosome number.

The graphic shows the citric acid cycle. A diagram of the citric acid cycle is shown. Acetyl C o A enters the citric acid cycle
vagabundo [1.1K]

Answer:

It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.

Explanation:

Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)
