Select the correct answer. which sentence describes an object that has kinetic energy? a. a seagull sits on top of a fence post.
ololo11 [35]

" a boat sails across the ocean" possess Kinetic energy. hence option d is correct.

<h3>What is Kinetic energy?</h3>
  • Chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, and rest energy are only a few of the many different types of energy that exist. Potential energy and kinetic energy are the two basic categories that can be used to group them.
  • An object's kinetic energy is what drives its motion. Kinetic energy can be converted into other types of energy and transported between objects.
  • The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.

The indentation on the medial surface of each lung through which pulmonary and systemic blood vessels, bronchi, lymphatic vessel
natulia [17]

Answer:

Hilum.

Explanation:

Hilum may be defined as the type of the depression or the fissure and may present in kidney known as kidney hilum, present on spleen and the lungs. This is also known as hilus.

The hilum marks the entry and exit of the nerves and the blood vessels. The lung hilum is a triangular like depression through which the blood vessels, capillaries and the nerves enter and leave in the lungs and connects the other organ of the body.

Thus, the correct answer is option (d).

Angiotensin II is a potent ____________ that helps regulate blood pressure. Angiotensinogen, is an inactive hormone synthesized
Hatshy [7]

Answer:

Angiotensin II is a potein VASOCONSTRICTOR that helps regulate blood pressure. Angiotensinogen, is an inactive hormone synthesized and released continuously from the LIVER. Its activation, which occurs within the BLOOD, is initiated by the enzyme renin. Renin is released from the juxtaglomerular apparatus of the KIDNEYS in response to either (1) LOW blood pressure (as detected by decreased stretch of BARORECEPTORS within granular cells, or by decreased NaCl detected by CHEMORECEPTORS within macula densa cells); or (2) stimulation by the SYMPATHETIC  division. The sequential action of renin and angiotensin converting enzyme (ACE) causes the formation of angiotensin II (the active form of the hormone).

Explanation:

Angiotensin is a peptide hormones that regulate blood pressure by causing increase in blood pressure through vasoconstriction. It is a part of the renin- angiotensin system that regulate the internal pressure of the blood. It is stimulated when the level of blood pressure reduces or there is an decrease in the sodium chloride in the blood. It effects is to vasoconstrict the blood vessels thereby increasing the blood pressure in the vessels. Angiotensinogen is the inactive hormone synthesized by the liver and upon activation through baroreceptors or chemoreceptors, the liver releases angiotensinogen into the blood stream to be ctivated by the enzyme secreted from the kidney's juxtaglumerular apparatusand then activated to teh angiotensinogen I, angiotensinoI is then activated into angiotensin II by the angiotensin II by the angiotensin converting enzyme. Angiotensin also causes the increase in the aldosterone secretion from the adrenal cortex to promote the retention of sodium by the kidneys, this also helps to increaee the blood pressure. Various receptors helps in signalling the body to a reduced blood pressure level. This includes the baroreceptors which are pressure receptors and detect changes in pressure of the blood; chemorecptors which are chemical receptors that detect the change in the concentration of sodium and chloride ion in the blood. All this function together with the sympathetic division of the CNS to help the body regulates its change in blood pressure in a given time.
