Answer:

(B) open stomata only at night, limiting water loss because of heat and low humidity.

Explanation:

CAM plants are found in the regions characterized by very hot and dry environmental conditions. These plants reduce the water loss through transpiration by exhibiting CAM photosynthesis.  

They open the stomata during night time when the air is cooler and rich in moisture. They take in CO2 during night time and fix it into the oxaloacetate which in turn is converted into malate and is stored in the vacuoles.  

During day time, stomata remain closed to prevent water loss and the CO2 trapped during night time (released by decarboxylation of malate) enter the Calvin cycle.

​a client with hypovolemia has been prescribed intravenous fluid at 125ml/hr. the iv site to provide hydration has infiltrated.
Levart [38]

The following are the steps the nurse would take to treat the infiltrated site:  

1. Stop the infusion and remove the catheter

2. Elevate the extremity

3. Encourage an active range of motion

4. Apply a cold or warm compress depending on the solution infusing

5. Restart the infusion proximal to the location or in another extremity

Now, in order to address hydration requirements of the client, the nurse will have to begin a novel peripheral intravenous in another extremity or to again start the infusion if intravenous access has been created.

You were able to radioactively tag and thereby trace an amino acid that is used to make insulin, a hormone that will be exported
Mnenie [13.5K]

Answer:

B) rough ER → Golgi complex → Golgi vesicle → extracellular fluid

Explanation:

  • Insulin is synhtesized by beta cells of pancereas (preproinsulin).
  • Insulin enters the rough endoplasmic reticulumn in its inactive form (proinsulin).
  • The rough endoplasmic reticulumn converts it to active form (insulin).
  • The rough endoplasmic reticulumn transfer the insulin to glogi comlpex
  • The Golgi complex secrete it in golgi vesicles to cytoplasm.
  • On the stimulation of beta cells insulin is secreted to extracellular fluid..

Define the five systems. Be sure to include enough information to distinguish each system from the others. (Site 1)
VladimirAG [237]
By definition, a body system is primarily comprised of different organs and tissues that work one another to achieve a common body process. These body systems would include:

Circulatory system - concerns with the circulation of blood
Digestive system - breaking down of food particles 
Skeletal system - composed of bone structures serving as our body's framework
Nervous system - composed of nerve cells that responds to different stimuli
Respiratory system - concerns of utilising the entry of oxygen and the exhalation of carbon dioxide.

Which pituitary hormone causes liver cells to release somatomedins that increase the rate of uptake of amino acids by cells such
Goryan [66]

Question: Which pituitary hormone causes liver cells to release somatomedins that increase the rate of uptake of amino acids by cells such as skeletal muscle fibers?

follicle-stimulating hormone

prolactin

thyroid-stimulating hormone

growth hormone

Answer:

growth hormone

Explanation:

Somatomedins are growth factors. The growth hormone makes the cells such as liver cells, skeletal muscles, bones, etc. to secrete the somatomedins. The somatomedins from the liver enter the bloodstream to reach the target cells. The somatomedins make the skeletal muscles, bones, etc. to absorb amino acids into the cells so as to facilitate protein synthesis. This growth factor also downregulates the breakdown of proteins. This is how growth hormone triggers the growth of muscles and soft tissues.
