Physical fitness is a medical term describing the effect of exercise on body systems and disease prevention. The body’s ability to function efficiently and effectiveness' it should contain health-related physical fitness and skill-related physical fitness. Physical fitness includes metabolic fitness and bone integrity. It is associated with person’s ability to resist hypokinetic diseases.
Optimal physical fitness is not possible without regular exercise.
A very strong relationship. I'll take the easiest example :the bees. They are so important for our planet. Without them, we and all living creatures on earth would be on track to dispariton. Let me explain why. At first, the bees need the nectar from flowers to make honey ( source of food ). As they pollen from flower to flower, they transport pollen on their tiny little legs and in this way, they help the plants to reproduce themselves. If, for some reason, there will be no more bees. Plants and flowers will not thrive, plants will be eaten without having contribued to the productivity of the species and they will go out. No plants, no more veggies or fruits for herbivorous and humans, no more herbivorous no more food for carnivorous, etc. Also, without plants, there will be less oxygen on our planet. Slowly the fauna and flora will die on earth and then it will be our turn. That is why relationships with plants and insects are so important. Plants produce oxygen for all of us and they are a natural and healthy source of food and insects help plants to survive and thus save the species.
Answer:
Vesicles
Explanation:
Serotonin is a neurotransmitter that transports signals or messages between neurons.
Most neuronal cells have vesicles in their interior, which are organelles that store neurotransmitters for exportation -by exocytosis- or from recycling -by endocytosis-. These vesicles also protect the neurotransmitter from the enzymatic action.
Vesicles form in the cellular soma, from where they are transported to nervous terminals. Once the vesicle releases the neurotransmitter to the intercellular space, their membrane remains available in the plasmatic membrane to be reused.
The neurotransmitter concentration in the vesicle interior is related to the storage system and the <u>transport system</u>. There are <u>specialized transporter proteins in the vesicle membrane</u> that are involved with the introduction of the molecule to the organelle.
In the exposed example, transporter Trans B might be located in the vesicle membranes, and hence could be found in the cytosol of the cells.
That as you increase in trophic level 1/10th of the nutrients is lost. Starting at the consumers (plants) all the way to humans.
a. chloroplast and cell wall
The chloroplast contains chlorophyll, which is the stuff that makes plants green. So animals do not have a chloroplast. Only plants have a cell wall and it is what helps plants maintain their shape. Hope this helped! :)
