This evidence supports the claim that some emotional reactions may occur without conscious thinking.
Thalamus is a small brain area located above the brain stem, with the main function of sending motor and sensory signals from the spinal cord and the mid-brain structures to the cerebral cortex.
Amygdala is a small brain region, which is part of the limbic system. It is considered the emotional control centre of the brain since it regulates emotions, survival instincts and some memory functions.
It has been proven that visual input is directly sent by the thalamus to the amygdala, which can trigger some emotional responses (such as fear) without any conscious processing.
Answer:
Up-regulation.
Explanation:
Hormones may be defined as the chemical messengers of the body that can transmit information and maintains homeostasis. The hormones can directly go into the bloodstream and may release through the special ducts.
The receptors of the hormone is required for the binding of the receptors. To maintain the normal homeostasis of the body, the body shows the up regulation and down regulation. In up regulation the hormone levels increases in the body by increasing the receptor on the specific target organ.
Thus, the correct answer is up regulation.
<span>Point mutations are of two types: Substitutions of bases that are the change of one base of DNA by another. And Transitions that are replaced on a pyrrhic basis by another pyrrhic or a pyrimidine by another pyrimidine. Transversions: substitution of a pyrrhic base by another pyrimidine or vice versa. These mutations are negative because they affect only one of the nucleotides, and therefore, only one triplet of bases are affected. When the mutation does not affect the individual it is a silent mutation. Chromosomal mutations Changes in the structure of the diploid chromosomes, where one of the chromosomes has a mutation, will have another normal. They can hinder the process of meiosis in the carrier since it hinders the correct pairing of the homologous chromosomes. It would produce an unfeasible offspring or with mutations.</span>
Chromatin is the component that specifies the nuclear contents during inter-phase.
<u>EXPLANATION:</u>
- The term inter-phase is the type of phase in which the cells would exhibit in all parts of its life.
- Chromatin is a term used to explains the components and contents of the nuclear in its inter-phase.
- A cell grows normally and duplicates its internal structure, the DNA, during inter-phase.
- Then it divides during the phase called mitosis after inter-phase.
