<span>A tropism is a movement of an organism toward or away from a stimulus. A positive tropism is when the organism moves toward the stimuli. A negative tropism is when the organism moves away from the stimuli. So, your answer will be negative tropism, since the stem is growing up and out of the soil, AWAY from gravity.</span>
Answer:
A) Calcitonin injection
Explanation:
Parafollicular cells or C-cells of the thyroid gland produce a hormone which is involved in the regulation of calcium levels in the blood. This hormone is Calcitonin. It works in an antagonistic manner with the Parathyroid hormone (PTH). Calcitonin decreases the calcium level in the blood by increasing absorption of calcium ions in bones. In osteoporosis, when the patient is given the injection of hormone calcitonin, it produces and increase in bone mass because it negatively affects the rate of absorption of bone by the osteoclasts.
Answer:
<em>The more the diversity in a location, the more is the diversity in organisms. </em>
<em></em>
Explanation:
Every area has a specific environment which is favorable for the survival of particular species adapted to live in that environment.
If there is such diversity in North California's environment, we will find that the population of beetles will be abundant in areas which are favorable for the survival of the beetle population. It may happen that with the passage of time, the beetle population might evolve and adapt to live in other areas too. Changes in habitat makes species diversity favorable.
