What is the function of the subplate neurons? Choose the correct option.
Semmy [17]

Answer: C) The subplate neurons attract the appropriate thalamic axons to the different parts.

Explanation:

Subplate neurons are the first developed neurons can be found in the cortex of mammals. These neurons disappear during the process of postnatal development and due to functional maturation.

These neurons are sensitive to the injury, when the humans experience cognitive and motor defects.

These neurons attract the thalamic axons and receive the synaptic inputs through the thalamic axons thus helps in establishing the link between the thalamic axons and the target layer IV. The signals are distributed from the thalamic axons to different parts of the body.

Tpy6a [65]

Explanation:

Scientists indicate that high levels of CO2 can affect the way fish behave, so that they swim towards the odors of predators instead of maintaining distances and even perceive sounds that normally deter them from going to habitats of risk. These abnormal behaviors are related to the effect of carbon dioxide on how the brain processes signals from sensory organs.

Answer:

2.Biotic factors are dependent on abiotic factors for food and protection.

3.Abiotic factors affect the type and number of organisms that live in a particular ecosystem.

Explanation:

An ecosystem is an environment that contains both living and non-living parts that actively interacts together.

The living part of the ecosystem is the biotic factors and the non-living parts are the abiotic factors.

  • The biotic components actively depends on the abiotic component for nourishment.
  • This is exemplified through the process of photosynthesis.
  • Also, the shelter of organisms are derived from the abiotic factors.
  • The abiotic factors have significant impact on the type and number of organisms that live in an ecosystem.

Why is it important for scientists to study vog?
coldgirl [10]

Answer:

b. to alert communities to potential health risks

Explanation:

Vog is defined as the form of air pollution which is caused by the emission of sulfur dioxide and other particles formed due to reaction of oxygen and moisture with volcanic gases in the presence of sunlight.

Scientists or volcanologist study vog to save life of people around the volcanic sites. As volcanic eruption can cause several helath risks<em> such as suffocation, respiratory problems, skin diseases, eye injuries and conjunctivitis.</em>

So, They predict the health risk by evaluating different gases in the vog and alert people to take precautions to be safe.

Hence, the correct option is b.
