The neurotransmitter GABA, which helps to control the preciseness of the signal, sent from one neuron to another, decreases with aging. GABA is the neurotransmitter that plays an important role in behavior, cognition, and the body's response to stress. It is the primary inhibitory neurotransmitter in the brain and plays a role in cognitive decline as we age.

Answer:</h2>
Removal of the tarnish from the silver is a <u>physical change</u>.
<h2>
Explanation:</h2>
The type of change which doesn't produce any new substance is called as physical change. Tarnish refers to the thin black layer that is formed on the silver. Formation of tarnish is chemical change as due to oxidation a black color layer is formed.
On the other hand, removal of tarnish from silver is considered as physical change as no new product is formed and only we are obtaining the silver in its pure form.
Answer:
The correct answers would be maintain chromosome number through generations and cause genetic variations by recombination.
In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.
It helps in the formation of gametes in sexually reproducing organisms.
These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.
In absence of meiosis, the chromosomal number would have doubled after each generation.
In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.
During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.
D) 68.6 m/s
Final Velocity = Initial Velocity - (Gravity)(Time)
Final Velocity = 0 m/s - (-9.8 m/s)(7s)
Final velocity = 68.6 m/s
