False
Frigid zone is the one near poles
The correct answer is false and here is why:
Clear cutting refers to the cutting of trees, specifically all of the trees in one select area. Replanting is not done and this leads to deforestation.
Controlled burns have a completely different affect. They burn the under brush to help keep the soil rich with nutrients, plus they also help to prevent large crown fires that burn down whole forests from happening.
Clear cutting is a bad thing and controlled burns are a good limiter for a forest.
Answer:
b. They express the appropriate receptor.
Explanation:
The signal transductions are extraordinarily specific and sensitive. Specificity is achieved by a <u>precise molecular complementarity between the signal molecules and the recepto</u>r. For example, the thyrotropin-releasing hormone produces a response in cells of the adenohypophysis, but not in hepatocytes, which lack the receptors to this hormone.
the constants are the type of food given to the fish.
Photosynthesis uses sunlight energy to make glucose (energy stores). A by-product of photosynthesis is oxygen. plants use water and sunlight to grow and they produce oxygen. Animals eat plants, use oxygen and breathe out carbon dioxide. Since the space station is in the shadow of the earth, the plants are unable to complete the process of photosynthesis and the carbon dioxide that is being produced by the humans cannot be utilized by the plants due to no sunlight. Therefore the carbon dioxide is going to continue to build up as the energy storage molecules are being depleted and not replenished.
