The soil on the valley floor because it would not have runoff. Hope this helps.
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.
A medical researcher measured the diastolic wall thicknesses of the arteries in a young, healthy test subject. The test subject came back 20 years later to have the measurements repeated. The measurements revealed that the subject's artery walls were half as thick as they were originally. Which of the following is the most likely long-term effect if the measured trend continues?
b) Arteries will be unable to withstand the pressure exerted by the heart, causing an aneurysm
Answer:
option D
Explanation:
Negative feedback is a mechanism in which function of a cell or an organ is decreased. It lessened the output of a system and maintain system function which is known as homeostasis. It is a regulatory mechanism of normal physiology. Some of examples are
blood sugar level regulation, regulation of blood pressure, thermoregulation and many more.
Answer: Mitochondria release energy by the breakdown of the organic food and produce carbon dioxide and water. Chloroplast helps in storing the energy and uses carbon dioxide and water to make glucose (energy).
