Answer 1

Answer:

1. A

2. D

3. B

4. C

Explanation:

1. Lysosomes are properties only found in animal cells.

2. Prokaryotic cells such as bacteria present ribosomes, a cell wall but lack a nuclear memebrane.

3. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole.

4. Some viruses reproduce using the lytic cycle. In the lytic cycle, the virus attaches to the host cell and injects its DNA, therefore reproducing inside of a cell.

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.

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.

A tertiary consumer is an animal that obtains its nutrition by eating primary consumers and secondary consumers. Usually tertiary consumers are carnivorous predators, although they may also be omnivores, which are animals that feed on both meat and plant material. Function of Tertiary Consumers

Answers

Answer:

The function of tertiary consumers is to keep the population of primary and secondary consumers under control, in addition to serving as food for quarternary consumers.

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.

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.

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.
