Answer;

-Presynaptic neuron

Explanation;

-When a nerve impulse travels from neuron 1 to neuron 2, neuron 1 is known as the presynaptic neuron.

-This is a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.

- A postsynaptic neuron is a neuron to the cell body or dendrite of which an electrical impulse is transmitted across a synaptic cleft by the release of a neurotransmitter from the axon terminal of a presynaptic neuron.

Discuss one of the major issues in toxicology from any perspective.
tangare [24]

A controversial issue of toxicology is the use of chemical additives in food.

Food additives are substances intentionally added to foods for the purpose of preserving, enhancing or modifying their physical, chemical, biological or sensory properties without impairing their nutritional value. However, it is necessary to control the use of these substances, as ingestion of these substances may pose health risks.

Additives are found in most processed foods, such as cookies, breakfast cereals, soft drinks, jellies, artificial juices, candies and a host of other foods in the diet of Brazilians, especially children.

Thus, its consumption should be controlled, as the health risk is confirmed by a sum of scientific studies. The three main ills associated with excessive consumption of these substances are cancer, food hypersensitivity and attention deficit hyperactivity disorder.

Some audiences are even more vulnerable to consumption, such as pregnant women, the elderly, people with little food and children under three years. In the case of children the attention should be greater because the digestive and urinary systems are not yet fully prepared to process these substances.

The more industrialized the product, the more chemical additives it will have. The ideal is to prepare fresh products at home. However, as is often not possible, it is important that you read the label and choose the products with the least additives.

<u>The resting </u><u>membrane</u><u> potential would become </u><u>more positive</u><u> because researchers are taking negatively charged molecules out of the cell.</u>

Which methods were used to record the resting membrane potential and action potential of the squid axon choose all that apply ?

  • The squid axon's action potential and resting membrane potential were captured using the following experimental strategy.
  • Using a recording microelectrode inside the cell that is connected to a second electrode outside the cell .

What is cell membrane ?

  • All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
    A semipermeable lipid bilayer makes up the cell membrane.
  • The movement of materials into and out of the cell is controlled by the cell membrane.

What are the functions of a cell membrane?

  • The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out .
  • second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

A species that humans bring to an area where it did not previously occur is a(an):_________
Tasya [4]

A species that humans bring to an area where it did not previously occur is a(an): exotic species.

Exotic species are those that exist outside of their native geographic range, also known as alien, nonnative, nonindigenous, or introduced species. Exotic species are those that people have purposefully or accidentally introduced into ecosystems outside of the ones in which they have evolved. These introductions undoubtedly happen regularly in nature.

For instance, the Japanese native Kudzu (Pueraria lobata) was brought to the United States in 1876. Due to either a lack of imported individuals or inadequate adaptation to the ecosystem they join, the majority of attempts to introduce exotic species are likely to be unsuccessful. However, some species have preadaptations that can help them thrive even more in a novel setting.
