What happens when the spinal cord is injured A) the parts of the body using the damaged areas lose sensation
B) The effected neurons in the CNS regenerate gradually.
C) The path of impulses in the nervous system may be disrupted.
D) Both (A) and (B)

Answers

Answer 1
Answer:

Answer:

The answer is c)The path of impulses in the nervous system may be disrupted

Explanation:

A spinal cord injury causes apoptosis of the oligodendrocytes found on damaged areas of the cord, several days or weeks later. The death of these oligodendrocytes is another serious consequence of the lesion, since these cells are what make up myelin, which is the one that envelops the axons, accelerating the direction of nerve impulses. This apoptosis causes axons that are still intact to lose myelin, which incapacitates the spinal cord to communicate with the brain.
Answer 2
Answer: A and B. When a person injures their spine, body movements and neurons can become affected. The CNS or central nervous system is what controls all this.

Which process allows organisms to keep internal conditions relatively constant despite changes in external conditions? Homeostasis



Hibernation



Hypothermia

Answers

Answer:

Homeostasis

Explanation:

Walter Cannon elaborated the concept of homeostasis from the investigations

carried out by Claude Bernard, creator of Experimental Medicine.

The concept of homeostasis, as Cannon formulated it in his capital work,  the Wisdom of the Body implies a dynamic equilibrium, maintained interactively by the constant dialectic between internal kinetics and  variations of the external environment. Homeostatic regulation is set to different  levels, from molecular-subcellular to suprapersonal or social, through the  global consideration of the individual as a whole . The study of isolated aspects of this systematic organization must give us, for  strength, a partial vision. Human functioning is always influenced by a  hierarchically organized activity of suprasystems and related subsystems.
Homestasis is correct.

Scientists notice structural similarities between fossils of a land animal and an aquatic organism. They know the similarities are not a result of the two organisms having to adapt to similar environments. What can they attribute the structural similarities to?convergent evolution
common ancestry
transitional evolution
similar mating habits

Answers

The correct answer is common ancestry. Common ancestry is the explanation for species from completely different environments having similar features. For example: there is fossil evidence that whales are actually evolved from wolf-like animals due to fossil evidence of a transitional evolutionary stage (this is the fossil that can help provide evidence of this common ancestry) that shows a common ancestor between land mammals and whales.

When homologous structures are found in different groups, an ancestry relationship can be stablished between them. Otion B. Scientists can attribute the structural similarities to common ancestry.

Ancestry between groups

Fossils provide good information about the existing relationship between different groups,

  • ancient and modern
  • aquatic and terrestrial

The existing homologousstructures between these organisms might be relatively similar, suggesting a common origin.

These structures can show changes in the number of pieces composing them, their arrangement pattern, or their sizes and development degree. These differences reflect the changes that the groups suffered through evolution.

The pattern in which the composing pieces are arranged is useful to study the lineage evolution.

By looking at the structures' composition and arrangement, scientists can interpret how evolutive processes occurred.

Scientists can attribute the structural similarities to common ancestry.
