Answer:
The correct answer is "There are several mechanisms that explain why a hormone have different effects in different cells. These mechanisms include: multiple receptors for the same hormone, a single receptor coupled to different pathways and hormones interacting with receptors for other molecules".
Explanation:
Hormones are among the most versatile molecules of the body, responsible for different biological processes such as human growth, sex development and metabolisms. Hormones are responsible of these complex biological processes because they have drastically different effects in different cells. There are several mechanisms that explain why a hormone have different effects in different cells. These mechanisms include:
- Multiple receptors for the same hormone. For instance, there are multiple receptor for dopamine, a hormone and neurotransmitter responsible for different functions such as movement, memory, sleep and motivation.
- A single receptor coupled to different pathways. Most hormone receptors act with a cascade of signaling. This in consequence results in a single receptor interacting with different molecules having multiple effects.
- Hormones interacting with receptors for other molecules. One example is the action of one metabolite of progesterone named allopregnanolone. This metabolite interacts with GABA-A receptor, which gives it anxiolitic properties.
I am answering under the assumption that those are cacti in the desert. Well as we know, cacti are producers they have the ability to synthesize their own food using photosynthesis which is a process that converts solar energy into glucose “food”. It has the ability to be a good source to small animals with its fruits and seeds. An example is, some insects feed off the nectar from the cacti. A second reason is that cacti are carbon sinks meaning that they take in carbon dioxide. Just to familiarize you the formula for photosynthesis is CO2 + H2O + energy equals glucose + O2 . Without carbon dioxide none of it is possible. Without cacti, CO2 levels would increase leading to bad affects.
