The nurse made the right choice in removing the diaper from the baby because the cause of the excoriated skin is the baby's feces. The baby's diarrhea is causing a rash in the skin due to its acidity. By removing the diaper, it's allowing the skin to not be in contact with the acid.
Answer:
Sensors or sensory receptors must sense any change in blood glucose levels.
Explanation:
A feedback system includes a receptor, control center, and effector. The receptors serve to sense the deviation from homeostasis and send the nerve impulses or chemical signals to the respective control center. The control center receives input from receptors and sends nerve impulses or chemical signals to the effectors to bring about the desired change to restore homeostasis.
Negative feedback regulation of blood sugar includes sensing the rise or drop in blood sugar levels by sensory receptors. This sensory information is sent to the control center which in turn commands the effectors (pancreas) to secrete insulin or glucagon hormones to lower down or raise the blood glucose levels. Feedback regulation does not work in the absence of any of the components (sensory receptor, control center, and effector).
Answer:
When gases escape downward out the tail of a rocket, they push upward on the rocket.
Explanation:
Newton's third states that to every action there is an equal and opposite reaction. Examples
- If you hit your head on a wall, your head exert a force on the wall, the wall also exert an equal but opposite force on your head, which will cause pains on your head.
- When you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
Answer:
Cut open the plasmid and "paste" in the gene. This process relies on restriction enzymes (which cut DNA) and DNA ligase (which joins DNA).
Insert the plasmid into bacteria. Use antibiotic selection to identify the bacteria that took up the plasmid.
Grow up lots of plasmid-carrying bacteria and use them as "factories" to make the protein. Harvest the protein from the bacteria and purify it.
