I believe the answer is b hope this helps
Answer:
Newer layers of earth form <u>on</u><u> </u><u>top</u> of older layers, so as we dig, we can see further back in time. Comparing the fossils between the layers can offer evidence of change.
<u>Phyletic</u><u> </u><u>gradualism</u> - slow, but constant gradual change; supported by transitional species in the fossil record
<u>Punctuated</u><u> </u><u>equilibrium</u>- long periods of no change followed by short periods of rapid change. Can also be supported by the fossil record when no transitional species are found.
PZ120 is not considered to be an enhancer to transcription in the metallothionein 2a gene.
<h3>About metallothionein 2A.</h3>
Metallothionein-2 is a metallothionein protein that in humans is encoded by the MT2A gene.
In human it is expressed in;
- right lobe of liver
- olfactory bulb
- left uterine tube
- external globus pallidus
- right lobe of thyroid gland
- upper lobe of left lung
- Region I of hippocampus proper
- right lung
- left lobe of thyroid gland
It's molecular function are;
- Protein ion binding
- Zinc ion binding
- Metal ion binding
It helps in various biological processes;
- response to metal ion
- cellular response to interleukin-3
- cellular response to erythropoietin
- negative regulation of growth
- cellular response to zinc ion
- interferon-gamma-mediated signaling pathway
- cellular copper ion homeostasis
- cellular zinc ion homeostasis
- detoxification of copper ion
- cellular response to cadmium ion
- cellular response to copper ion
- nitric oxide mediated signal transduction
- response to bacterium

All the nerve processes radiating out beyond the brain and spinal cord, as well as all the neurons outside the brain and spinal cord, constitute the peripheral nervous system.
Spinal cord is the backbone present in the vertebrates. It is essential for the correct posture and erect body. It extends from the end of the brain till the hipbone. The spinal cord consists of total 5 types of bones called vertebrae, that are total 33 in number.
Peripheral nervous system consists of parts of nervous system outside the brain and the spinal cord. It involves cranial and spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

In humans, new neurons are continually born
throughout adulthood in two regions of the brain:
<span>·
</span><span>The subgranular
zone (SGZ), part of the dentate gyrus of
the hippocampus.</span>
<span>·
</span><span>The striatum;
however the adult-born neurons are a type of interneuron,
not a type that projects to other brain areas.</span>[5]
<span>In other species of mammals, particularly rodents,
adult-born neurons also appear in the olfactory
bulb. In humans, however, few if any olfactory bulb neurons are
generated after birth.</span>
