4 0

Explanation:

D. average hamster weight decreases with an increase in the daily amount of a drug until the hamsters reach a minimum possible weight.

Trend: There was a gradual decrease in the hamster's weight til a minimum was reached, after with the rate of its change in weight with treatment over time plateaued.

Trends are gradual notable changes or patterns over a series of data points on a line or curve of a graph. These allow for summarizing data and predicting results. A data summary provides a comprehensive report of experimental findings. This makes the analysis of data easier by answering key research objectives outlined in the experimental procedure. Summaries allow for tracking trends and procedural changes, observations and potential; this makes it easier to arrive at conclusions faster.

Neural control of gfr is mediated by ________ that innervate ________ receptors on vascular smooth muscle causing ________

storchak [24]

Neural control of GFR is mediated by Sympathetic neurons that innervate alpha receptors on vascular smooth muscle causing Vasoconstriction.

<h3>How is GFR regulated?</h3>

The sympathetic division of the nervous system regulates the GFR or Glomerular Filtration Rate.
GFR is the sum total of filtration rates of all the working nephrons in the kidney.
Sympathetic division comes into action when the mean arterial pressure is very low (below 80mmHg).
In response to low blood pressure, the medulla releases norepinephrine through sympathetic nerves.
Norepinephrine leads to activation of alpha receptors on arteries which cause vasoconstriction.
Alpha receptors are more abundant on afferent arterioles.
This leads to vasoconstriction (narrowing) of arteries supplying to the glomerulus.
This decreases blood flow to glomerulus, leading to decrease in GFR.

Research indicates that as levels of happiness increase, cortisol levels appear to increase as well. Please select the best answ

iogann1982 [59]

Cortisol hormones are stress hormones that increase blood glucose levels. When the level of happiness increases the level of cortisol does not increase.

<h3>What are cortisol and its function?</h3>

Cortisol is the steroidal hormone that is produced in the cortex of the adrenal glands and is discharged in the blood vessels when in stress or danger.

It has a variety of functions including regulation of the blood pressure, response to the stressful condition and increase of the metabolism of the body.

It also acts as happiness hormones along with adrenaline and oxytocin but is a major flight or fight hormone and increases the heart rate in dangerous conditions.

Therefore, the statement is false.
