In the early 19th century capturing merchant ships as prizes of war was the primary purpose of Privateers navy vessels.
<h3>What is

Privateers are furnished vessels that are possessed, prepared and officered by at least one confidential people, however cruising under a commission, as a rule called letters of marque, from a combative state, which engages the individual or people to whom it is conceded to assault and seize, adrift, vessels or other property of its foe.

Defects in transcription factors underlie some forms of cancer.
Your right J is sexual reproduction, and K is asexual reproduction. But sexual reproduction requires the presences of a male and a female. But other asexual reproduction doesn't, and just requires sexual maturity. They produce offspring in the form of spores for example.

Because they break down what they are made of
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.
