Question 21 Neurons of the cerebral cortex never dip into the medulla. O True O False

Biology
1 answer:
V125BC [204]3 years ago
5 0

Answer:

False

Explanation:

The cerebral cortex refers to the outer layer of the brain. This layer is formed by a thin film of nervous tissue that surrounds the surface of the cerebral hemispheres, with primates having a much more developed cerebral cortex than other animals.  

the cerebral cortex is a thin layer of neurons and neuronal connections which is embedded in the neocortex(the neuronal cells of the cerebral cortex which form in the deep layer), it is not homogeneous, since it is made up of six layers of cells, each with specific and specific functions.

kkurt [141]

Answer:

The larva gets dark pigment.

Explanation:

If scientists purposely injected an excess concentration of these proteins in the larva, the larva gets deep dark colour because this protein is responsible for the pigment colour in the larva of Drosophila. By increasing the protein concentration the pigment will also have a very dark colour. So we can conclude from this that increasing the amount of protein causes increase in the pigment colour.

How do plate tectonics explain the formation and metamorphic rocks?
Serga [27]

Metamorphic rocks are formed from other rock that has been subjected to very high temperature and pressure.

When one of the earth's plates comes in contact with another either by both traveling opposite directions, straight into each other, or from one slipping under the other (subduction zone), the pressure/friction of the plates against each other melts the rocks and after they cool they are metamorphic. Example is in Washington state when the Juan de fuca plate is going under the North American plate the pressure/friction of this melts the rocks which then form metmorphic rock.

Yakvenalex [24]

Neurotransmitters can affect postsynaptic cells by causing molecular changes in the cells.

The term "chemical messengers of the body" is frequently used to describe neurotransmitters. The nervous system uses these molecules to send information between neurons or from neurons to muscles. A neurotransmitter influences a neuron in one of three ways: excitatory, inhibitory or modulatory.

When a stimulus is potent enough, the chemical messenger neurotransmitter is transferred into the nerve impulse. If it is powerful enough, it will reach the postsynaptic cell and affect the structure of the neuron. And when signal transduction happens, everything mentioned above is completed.
