Which example best represents the adhesion, cohesion, and surface tension of water?

2 answers:

7 0

<span>The best example that represents the adhesion, cohesion, and surface tension of water is that water droplets forming a bead-like shape over a glass table. Cohesion: Water is pulled in to water. Adhesion: Water is pulled in to different substances. Adhesion and cohesion are water properties that influence each water particle on earth and furthermore the connection of water atoms with particles of different substances</span><span />

<span>To represent adhesion, consider droplets of water that fall onto a window as it is raining. These drops 'stick' onto the window until they evaporate or until are big enough to roll down the window. To represent cohesion, consider how water droplets rolling down a window quickly combine with other droplets to form a stream of water that flows down the window. To represent surface tension, consider a razor blade placed flat on it's side and it appears to 'float' on the water. However if placed in an upright position, it does not remain on top of the water.</span>

People with panic disorder show dysregulation of norepinephrine systems in an area of the brainstem called the:_________.a. basa

antiseptic1488 [7]

Answer:

B. locus ceruleus.

Explanation:

A nucleus present in the pons of brainstem responsible or involved in physiological responses to panic and stress is known as locus ceruleus.

Basically, locus ceruleus is responsible for the primary production of norepinephrine in the brain. The nucleus transfers the norepinephrine to whole cerebral cortex along with various other structures like amygdala, cerebellum, hippocampus, and spinal cord.

So, when there is a panic disorder due to norepinephrine dysregulation at the brainstem area which will be definitely locus ceruleus.

erastova [34]

The sets of alleles for each parent are Dm for the mother and DM, Dm, dM, and dm for the father. This information is fundamental for estimating genotype and allele frequencies in offspring.

<h3>What are alleles?</h3>

Alleles are gene variants for a given gene <em>locus</em>, diploid organisms inherit two alleles for each locus (one from each parent).

Gametes are germinal (haploid) cells that carry specific allele combinations.

The analysis of gamete combinations is fundamental to estimate genotypes and allele frequencies.

Describe the neural and renal mechanisms that control blood pressure.

Andrei [34K]

Answer:

The autonomic nervous system is the main neural regulator of circulation and blood pressure in the short term and beat by beat and exerts its function through various reflexes that regulate vasomotor tone, heart rate and cardiac output. At the renal level, the renin–angiotensin–aldosterone system is possibly the most important in the maintenance of arterial homeostasis.

Explanation:

Blood pressure is regulated by a series of interrelated autonomic systems and humoral reflexes, which continually adjust the determining elements of the system (heart rate, stroke volume, total peripheral resistance and circulating volume).The effective circulating volume is controlled by a series of reflex systems, which obtain information about the perfusion pressure (baroreceptors in the carotid bulb and aortic arch), plasma osmolarity (hypothalamus) and urinary sodium (distal tubule).The kidney has its own self-regulatory mechanisms. The reduction in renal blood flow is detected at the level of the mesangial cells of the juxtaglomerular apparatus, starting the renin-angiotensin system. The increase in angiotensin II produces on the one hand local vasoconstriction, and on the other hand stimulates the production of aldosterone by the adrenal cortex with the consequent tubular reabsorption of sodium and water.Antidiuretic hormone or vasopressin (released from the hypothalamus by stimulation of arterial baroreceptors and also by stimulation of angiotensin II) also acts at the renal level, which acts as a powerful and water-saving vasoconstrictor in the distal tubule.
