1: Explain why cellular respiration releases energy as an overall chemical reaction.
Brums [2.3K]

Cellular respiration is the metabolic reaction inside the cell to convert chemical energy into ATP. Biomass is the total mass of organisms at a trophic level.

<h3>What is exothermic reaction?</h3>

The type of reaction in which releases energy after its completion.

  • Cellular respiration releases energy because it is an exothermic process in which energy is released as a by-product of the reaction.

  • Organisms are larger in size at higher trophic levels, but their smaller numbers result in less biomass.

Thus, being exothermic in nature, cellular respiration releases energy and because of less numbers, there is less biomass at high trophic levels.

Which disease is the result of uncontrolled cell growth?
RoseWind [281]

Let's look at the definitions of each one. Then use the definitions to answer the question.


A. Diabetes: a disease in which the body’s ability to produce or respond to the hormone insulin is impaired, resulting in abnormal metabolism of carbohydrates and elevated levels of glucose in the blood and urine.


B. Sickle cell disease: a severe hereditary form of anemia in which a mutated form of hemoglobin distorts the red blood cells into a crescent shape at low oxygen levels. It is most common among those of African descent.


C. Down syndrome: a congenital disorder arising from a chromosome defect, causing intellectual impairment and physical abnormalities including short stature and a broad facial profile. It arises from a defect involving chromosome 21, usually an extra copy (trisomy-21).


D. Cancer: the disease caused by an uncontrolled division of abnormal cells in a part of the body.

a malignant growth or tumor resulting from the division of abnormal cells.



So your answer would be C. Cancer.

What would be the functional problems that would be experienced by a person in which the fiber tracts listed below have been cut
Ad libitum [116K]

1. Dorsal column-medial lemniscal pathways - It would prevent the body from receiving stimuli related to pain and temperature: Corresponds to sensory pathways related to an organism's proprioceptive awareness. It is through these pathways that sensory stimuli and electrical impulses are transmitted from the body to the brain resulting in the display of quick and efficient responses. If cut, the individual would not be successful in receiving stimuli related to pain and temperature.

2. Anterolateral pathways - It would also prevent the sensation of pain and temperature, in addition to hindering the perception of touch and pressure: Located in the anterior part of the lateral column, this pathway is responsible for the transmission of nociceptive information, generally related to pain awareness. and temperature. Its cut would not only make it difficult to transmit these factors, but it would also make it difficult to transmit extroceptive information to the cortex.

3. Spinocerebellar pathways - would hinder information about the position of body members and joints: This pathway is located between the spinal cord and the ipsilaterally in the cerebellum. It consists of thousands of axonal fibers whose main function is to transmit information about the location of the body members, arms and legs, in addition to their joints. Its cut would make it difficult, or even prevent this information from being captured by the brain.

4. Pyramidal pathways - It would prevent the union of the cerebral cortex to the motor neurons of the spinal cord: It is formed by several axons that extend between the cerebral cortex and the spinal cord passing motor information that would be interrupted if the path was cut.
