Answer:
See the answer below
Explanation:
Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways
- <em>Negative feedbacks</em>
- <em>Positive feedbacks</em>
Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat
Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.
The patient does
not respond adequately to fluid replacement and
was given an IV infusion of dopamine hydrochloride at 5 mcg/kg/minute. In addition, to
monitor that the drug is having the desired effect, the nurse should assess the
client for increased cardiac output. <span>At medium doses, which is between 4 – 8 mcg/kg/min, the dopamine
hydrochloride slightly increases the heart rate and improves contractility to
increase cardiac output and recover tissue perfusion.</span>
I don't see a graph but I would assume since there are more trees and plants there would be less carbon dioxide meaning the graph would start to go down over time since they turn the carbon dioxide into oxygen.
Answer:
Nucleus: The nucleus controls everything which takes place in the cell. It does this as it is the site of the cell's DNA. DNA contains the genetic code which is translated into proteins.
Explanation:
Oxygen diffuse from alveoli into capillaries and then into cells because it is needed for cellular respiration which occurs in mitochondria inside the cells.
