Prophase is the right answer
Answer:
Pine trees are conifers!
Explanation:
Your question was a bit confusing but I'm assuming you are asking which group does pine trees belong to. 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.
Answer: Outer hair cell
Explanation:
The hair cell is located in the brain and its responsible for amplification of sound. The hair cell length changes in response to stimulus. For amplification a low input is needed and the surrounding frequency must be close to basila membrane located in the inner hair cell. They can amplify low sound using their hair bubbles. The outer hair cell increase hearing sensitivity and a damage to it brings about low sensitivity.
Also, outer hair cell do not regenerate itself and a damage to it means a permanent damage.
Answer:
A. Aerobic respiration
Explanation:
The cell body of neurons have mitochondria which in turn serve as the site for ATP production. Nerve cells derive their energy by complete oxidation of glucose by the process of aerobic respiration. The enzymes required for aerobic respiration of glucose are present in mitochondria. The ATP molecules produced in cell bodies are delivered to the other parts of neurons to serve as source of energy during conduction of nerve impulse.
