Answer:
1.33 m/s
Explanation:
The formula for Kinetic Energy is given as:
Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.
Re-arranging the above equation and isolating v, we get
Putting values in this equation, we get:
Thus, the object is moving with a velocity of 1.33 m/s
Answer: Systolic pressure.
Explanation:
Every time the heart beats, it pumps blood into the arteries, which are vessels through which blood circulates from your heart to your tissues with the oxygen and nutrients they need. Blood pressure is the force of the blood pushing against the walls of the arteries, and is highest when the heart beats, pumping blood, which is measured as systolic pressure (i.e., when the heart contracts). On the other hand, diastolic blood pressure refers to the pressure of blood in the artery when the heart relaxes between beats (i.e., when the heart relaxes). Since there are two types of pressures, blood pressure readings are given in two numbers, with the top number being the systolic pressure and the bottom number being the diastolic pressure.
For example, if the systolic pressure measured in a person is 125 millimeters of mercury (mm Hg) and the diastolic pressure is 85 mm Hg, the blood pressure is recorded as 125/85.
So, <u>the systolic blood pressure is registered with the stethoscope when the cuff is deflated.</u> When two heartbeats are heard, the pressure gauge reading is recorded. <u>When the heartbeat ceases, the cuff pressure is released and the diastolic pressure is measured at this time.</u>
This process moves carbon from biotic to abiotic matter. Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.
Answer:
The intercalated cells in the distal convoluted tubule of a nephron can cause and increase or decrease in body pH.
Explanation:
The renal collecting duct is the nephron segment where the final urine content of acid equivalents and inorganic ions are determined.
Two types of cells regulate the acid-base and volume homeostasis.
Intercalated cells, which express acid-base transporters and vacuolar H+-ATPase, maintain an apropriate acid-base balance and principal cells that express the epithelial sodium channel ENaC and aquaporin 2, regulate electrolyte reabsorption.
Filtered bicarbonate is predominantly reabsorbed from the proximal convoluted tubule about 80% and the remaining bicarbonate is reabsorbed from the thick ascending limb of the loop of Henle, the distal nephron, specifically the distal convoluted tubule & the connecting tubule, and finally the cortical and both the outer and inner medullary collecting duct.
Intercalated cells are enriched in mitochondria, and express proteins involved in transport of proton equivalents such as vacuolar H+-ATPase, carbonic anhydrase II and bicarbonate transporters. There are two types of intercalated cells Type-A and Type-B.
Answer:
A. Erosion from wind, water, or ice removes crustal material.
Explanation:
Plain formation can occur in many different ways some plates some planes can form as wind, water and ice erode wear away or remove dirt and rocks on higher land.
Wind picks up and carries along small particles which can be abrasive against surfaces, slowly wearing them away to form more particles. The water and ice transport the fragments of rock and dirt as sediment down hillsides, where it is eventually deposited. This occurs until several layers of sediment are accumulated. Plains can also form at the bases of mountains where water carries a flow of sentiments downhill to flat areas where it further spreads out to deposit the sediment in a fan shape -this is called an alluvial plain.
