If you move a plant further and further away from a light source the level of O2 production would _______________ because the process of _____________________ slows and the process of _____________________ speeds up.
Answers
Answer:
1. Decrease
2. Photosynthesis
3. Cellular respiration
Explanation:
Photosynthesis in a plant requires light source to occur. The photosynthetic process gives oxygen gas (O2) as a waste product. This means that the production of oxygen is dependent on the intensity of light.
On the other hand, cellular respiration uses up or consumes oxygen in a plant. Hence, an increase in respiration reduces oxygen level if photosynthesis does not produce.
According to this question, If you move a plant further and further away from a light source, the level of O2 production would DECREASE because the process of PHOTOSYNTHESIS slows and the process of CELLULAR RESPIRATION speeds up.

This summer, you are returning to the research station in Costa Rica to follow up on the population of butterflies you have been studying. You are disappointed to find that there are fewer this year than last. In fact, at dinner your friends studying frogs and birds are complaining about the same thing. What type of influence do you suspect
Answers
Answer:
it is likely that there was an environmental disturbance that affected the population density of the species.
Explanation:
All animals have their survival and reproduction capacity directly linked to environmental quality. This is because these animals take from the environment all the resources needed to live and develop. In this case, when the environment is balanced and has the necessary resources for life, animals can survive longer and develop well, being able to reproduce, generating more animals that increase the population density of their species. However, when this environment is disturbed, the animals' survival is threatened, even failing to reproduce. This lowers population density.
In the case presented in the question above, it is likely that populations of butterflies, frogs and birds are decreasing due to environmental disturbances.

A general mechanism by which postsynaptic potentials are terminated involves Group of answer choices increased synthesis of the neurotransmitter molecule. enzymatic synthesis of the neurotransmitter molecule. reuptake of the neurotransmitter molecule into the axon through a membrane transporter. increased number of postsynaptic receptors. diffusion into glial cells.
Answers
Answer:
The correct answer is - reuptake of the neurotransmitter molecule into the axon through a membrane transporter.
Explanation:
The action of a neurotransmitter at the postsynaptic cell or postsynaptic potentials is terminated by any of these mechanisms that are enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.
After the desired biological response by postsynaptic potentials, in order to avoid over stimulation or termination of the postsynaptic potentials the neurotransmitter is taken back into the axon through a membrane transporter. This mechanism is to maintain a balance.

Explanation:
As stated in the question above, tertiary consumers are those who feed on secondary and primary consumers within the food chain. They represent a very important trophic level, in addition to allowing the transfer of energy between living beings to flow normally, they manage to control the populations of primary and secondary consumers, which keep nature in balance. In addition, they serve as food for other consumers, the quarternarios consumers.

Read the passage “ a river for everyone”, then answer two questions below.( the entire passage is in the image above)
1. Are there any limits on what you can change? For example, it would not be realistic to
remove all of the farms. Is there anything that people cannot compromise on?
2. What else would you need to know to come up with a plan of action? Where could you
get that information?
Answers
Answer:
1. Moving the facilities such as crops, lawns, golf courses, and sewers etc would be unrealistic to change because many of the owners would not comprise (costs so much already), yet there are solutions. For example, the town can restrict farmers from poluting the rivers with pesticides as well as fining them and the house developments golf courses and land owners in which the money can be used towards the filteration cost. Another idea would to build cheaper wells to soak up water from different river locations or build barriers around settlements from the river. Another idea would to simply grow natural filters such as using the trees and soil they already had.
2. Of course their are limits such as costs, and figuring out the landscapes of where to build wells, add soil and trees (trees take time to grow) and more that would need plan of action from community leaders in which the people would need to speak with the advisors or the management of the buildings nearby. Without clean water people will get sick or die, and building managers need healthy people to live in their houses and work and grow crops so they'll have to make change.

Answers
Answer:
The correct answer is - block the reuptake of norepinephrine and serotonin into the terminals.
Explanation:
Tricyclic antidepressants drugs help in increasing the levels of hormones such as norepinephrine and serotonin, two neurotransmitters. The level of these hormones are increased by blocking the reuptake of these neurotansmitters and hormones back to axon terminal.
Reuptake of neurotansmitters and chemical messangers is the general mechanism of the balancing the horone levels in the body.
