As DNA replication begins the DNA molecule is broken apart into two complementary strands. DNA replication is the process by which DNA makes a copy of itself during cell division. The process occurs in all living and is the basis for biological inheritance. The process starts with the separation of DNA strands in the double helix. Then replication for is formed followed by the binding of bases to each strand. Then the last step is termination of the Replication process

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.

Which statement best describes a cause and its effect during the process or muscle contraction?​
Alisiya [41]

Answer. The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.

2.2.2 Quiz: Transcription
Karolina [17]

<u>Answer</u>:

Actions happens after transcription ends is "An mRNA molecule leaves the nucleus of the cell."

<u>Explanation</u>:

Transcription is the process of formation of mRNA from DNA. DNA is the genetic material which carries all the information for the formation of mRNA and then protein. Transcription occurs in nucleus, but as soon as the mRNA is formed it unwinds from the template DNA stand and moves into the cytoplasm for the next process i.e. translation. Translation occurs nearer to the ribosomes, it is the formation of protein from mRNA strand. combinedly transcription and translation are referred as the central dogma of the molecular biology.

Which of the following practices that are needed to run a nuclear power plant has a negative impact on both air and water
BartSMP [9]

Answer:

The options are

a.cooling of the power plant

b.mining of uranium

c.storage of radioactive waste

d.monitoring the reactor

The answer is b.mining of uranium

Explanation:

Uranium is known as a radioactive element which is used as a fuel to power a nuclear energy plant. Mining of uranium could cause it to mix with air and water which results in contamination.

When contamination occurs and it gets into the body of humans or animals by inhalation or ingestion it poses a high risk of cancer and kidney damage.
