Answer:

All blood types are made compatible with each other.

Explanation:

The different types of blood showed that not all blood types are compatible with each other. This is the reason why when a doctor transfer blood, this has to be compatible with the person's blood. Otherwise, the immune system will recognize the blood cells as antigens and proceed to destroy it.

Red blood cells in its surface can have different types of proteins, the proteins or lack of it that a person has determines the type of blood (A, B, AB). Also, if the cell has the Rh protein it will be positive, and if it does not have it, it will be negative. In total, we have eight blood types A+, A-,B+, B-,AB+, AB-,0+,0-  and the compatibility depends on the proteins that a person has.

Ulleksa [173]

Answer:

The function of the central nervous system is to control all function of the body and mind and to integrate all sensory information received and and respond accordingly.

The central nervous system is made up of the brain and the spinal cord and its neurons.

The resting state of a neuron is  -70 mV (mV=millivolt) - which means that the inside of the neuron is 70 mV less than the outside of the neuron, therefore, at rest, there are relatively more sodium ions outside the neuron (which are negatively charged) and more potassium ions inside that neuron (Positive charge)

bulgar [2K]

Default network


When the brain is unoccupied, an fMRI indicates that blood continues to flow via a web of brain regions called the default network.

The default network is a web of brain regions that have activity that corresponds greatly with each other and different from other networks within the brain. The default network is active when an individual's attention is not concentrated on the external environment and it is measured with the functional magnetic resonance imaging technique (fMRI).
