Free palmitate is activated to it's coA derivative(palmitoyl-CoA) in the cytosol before it can be oxidized in the mitochondria.
n200080 [17]

Answer: hydrolysis of intermediate palmitoyl Co A ,with loss of labeled CoA.before reaching the matrix gives the answer

Explanation:

This is because when the labeled Coenzyme A of the Plamitate combines as Palmitoy-CoA with oxaloacetate to form intermediate (palmitoyl-CoA )in Citric Acid cycle:

CoA is hydrolysed with loss of the labelled CoA which returns to the cystosol. Therefore, the labelled CoA does not reach the matrix of the mitochondrial,but returns to the Cystosol.

Consequently, the CoA in the Cystosol will be labelled in palmitoylCoA and the one in the matrix of the liver mitochondrial will be non radioactive(,will not labelled).

Activation of the sympathetic nervous system A. increases salivation and increases blood pressure. B. decreases salivation and i
yaroslaw [1]

Answer:

B. decreases salivation and increases blood pressure

Explanation:

The sympathetic nervous system is part of the autonomous nervous system which controls involuntary responses of the body such as salivation and blood pressure.

The sympathetic nervous system  is majorly responsible for body actions that are produced when threat is perceived. It generates responses referred to as the “fight or flight” response. Examples of such responses include, increased breathing, increased high blood pressure, dilation, decreased salivation, etc.

Activation of the sympathetic nervous system would result in rise in the blood pressure as can be witnessed by someone whose body has perceived a threat or reacting to a stressful situation.

The control of salivary production by the sympathetic nervous system  leads to the release of noradrenaline which acts on certain receptors that results in decrease in the production of saliva. This is evident in a person that is facing a threat also.

(<em>D</em><em>I</em><em>S</em><em>C</em><em>L</em><em>A</em><em>I</em><em>M</em><em>E</em><em>R</em><em>:</em><em> </em><em>It </em><em>c</em><em>hanges with variation in atmospheric pressure, temperature and humidity.</em><em>)</em>

3) The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides.

4) WIND

The uneven heating of the atmosphere causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
