Specific regions of eukaryotic chromosomes contain sequence elements that are absolutely required for the proper transmission of
grandymaker [24]

Answer:

A. terminators of replication.

Explanation:

For the proper transmission of genetic information from a mother cell to each daughter cell, the cell copies or replicates its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set. And in order to duplicate and segregate correctly, chromosomes must contain three functional elements which are origins for initiation of DNA replication, the telomeres and the centromeres. Terminators of replication is not a required element.

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.

Intermediate photographs should show the relation of evidence to other parts of the crime scene. A. True B. False​
hichkok12 [17]

Answer:

True.

Explanation:

<em>"adjective </em>

<em>adjective: intermediate </em>

<em>coming between two things in time, place, order, character, etc."</em>

Pictures correlating to the crime scene are like puzzles to find out the other meanings or cause of another picture.

For example:

A opened jug of milk sits on a table.

There's a blurred figure of a hand hitting the jug.

The jug is now laying on the table, dripping everywhere.

-

If we take out the middle picture "There's a blurred figure of a hand hitting the jug.", then we would not know what hit it over. Did someone bump into the table? Did a cat climb onto the table and release its almighty strength onto it? All we would know that it was once standing upright.

TLDR; Without intermediate pictures, it would be hard to grasp what happened on the scene. Intermediate pictures all have something in common with each other to help interpret what occurred to the viewer.
