Answer:
The blood pressure is increased to pump more blood to distribute more oxygen to the muscles
Explanation:
When we do activities that demand heavy exercise like running, our body needs more oxygen to carry out property the exercise. Oxygen is transported to muscles by the circulatory system (principally blood), our heart starts to pump faster the blood ( increase the blood pressure) to distribute the oxygen between muscles, consequently, we start to breathe faster to increase the oxygen intake.
The organelle the question is referring to is called the chloroplast. I hope this helps; have a good evening!
Answer:
The minimum mass of dissolved cholesterol that the new system must be able to detect is 0.43 milligrams.
Note: The question is incomplete. The complete question is:
<em>GenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect borderline high levels of dissolved cholesterol (170, to 200. mg/dL), using a blood sample that is as small as 250 μL Calculate the minimum mass in milligrams of cholesterol that the new system must be able to detect Be sure your answer has the correct number of significant digits.</em>
Explanation:
Range of the equipment to detect cholesterol in blood = 170.0 to 200.0 mg/dL
Minimum amount of cholesterol that can be detected by instrument = 170 mg/dL
Volume of blood sample = 250 <em>μ</em>L= 0.0025 dL (1 dL = 100000 <em>μL)</em>
Amount of dissolved cholesterol in 250 <em>μL</em> sample of blood =
170 mg/dL * 0.0025 dL = 0.425 mg
The minimum mass of cholesterol that the new system must be able to detect is 0.43 milligrams.
Answer:
D
Explanation:
The neuroendocrine system is made up of the cell in the body that ‘sit’ between the nervous system and the endocrine system. These cells are like the pituitary gland, islets cells of the pancreas, thyroids, and etcetera. They receive nerve impulses from nerves connected to them. The impulse then triggers them to release respective hormones into the blood.
