People who experience severe blood loss go into a condition known as hemorrhagic shock. Shock occurs when the blood volume retur

ning to the heart is reduced. The heart responds by trying to increase output, which can result in the patient bleeding to death if they are not treated in time. Is this an example of negative feedback or positive feedback? Explain your answer.

Hemorrhagic shock occurs when the body begins to shut down due to large amounts of blood loss. People suffering injuries that involve heavy bleeding may go into hemorrhagic shock if the bleeding isn't stopped immediately. Common causes of hemorrhagic shock include: severe burns

In this type of shock, disruption of the sympathetic nervous system, as occurs in spinal cord or brain injury, causes widespread vasodilation. ... This form of shock results from decreased blood volume, often due to trauma. Inadequate blood returns to the heart, reducing cardiac output and blood pressure.

The obvious cause of hypovolemic shock is blood loss, but that isn't all of it. The loss of blood can come from external or internal bleeding due to illness or injury. Most of the time, hypovolemic shock will be a complication of another condition.

What would happen if photosynisis stoped happing on earth
Neporo4naja [7]

We can confirm that the absence of photosynthesis on Earth would cause a mass extinction of most of the species on the planet.

<h3 /><h3>Why would the absence of photosynthesis be so harmful?</h3>

The process of photosynthesis is extremely important as it produces oxygen as a byproduct. The absence of this process on Earth would limit the available oxygen in the atmosphere which would at some point be entirely consumed. From then on, most species on the planet would die out as they require oxygen to live. Most plant species would also die off as they use photosynthesis to sustain life.

Therefore, we can confirm that the absence of photosynthesis on planet Earth could be considered an apocalyptic event as it would cause a near-complete extinction of life on the planet.

A very common type of red–green colorblindness in humans is caused by a mutation in a gene located on the X chromosome. Knowing
Harrizon [31]

Answer:

50%

Explanation:

According to the given information, the allele for the red-green colorblindness is inherited in an X linked recessive manner. Let's assume that the allele X^c is responsible for red-green colorblindness. The woman is normal but had a colorblind father (X^cY). Fathers give their X chromosomes to the daughters while their Y chromosome is transmitted to their sons. The sons get their X chromosomes from the mother.

The colorblind father has transmitted the X-linked allele for the red-green colorblindness to his daughter. Therefore, the genotype of the woman is X^cX. The woman would produce two types of eggs: 50 % with X^C and 50% with X. Therefore, 50% of sons of this woman would get X linked allele for the red-green colorblindness and would be affected by the disorder while the rest 50% of her sons will be normal.

Systems that use massively parallel systems of processors whose architecture is based on the human neuron structure are called
sashaice [31]

Answer:

Neural networks

Explanation:

The neuron is the structural and functional unit of the nervous system. The neuron is also known as a nerve cell. The neuron is the largest cell of the body that helps to communicate or transmit signals. A neuron has an axon body, dendrites, and terminal region. The transmission of the signal from one neuron to another through the axon terminal.   Large numbers of neurons are present in the human body system that coordinates the whole body system. Neural networks contain a massive amount of neurons whose architecture is based on neurons. So, the correct answer to the given question is neural networks that use massively parallel systems based on neurons.
