<h2>C) option is correct </h2>
Explanation:
- The spinal cord has numerous groups of nerve fibers going towards and coming from the brain
- These have been collectively called the ascending and descending tracts of the spinal cord, respectively, these tracts are responsible for carrying sensory and motor stimuli to and from the periphery (respectively)
- The ascending tracts transmit sensory information from the sensory receptors to higher levels of the CNS
- The descending tracts originate from different cortical areas and from brain stem nuclei
- The descending pathway carry information associated with maintenance of motor activities such as posture, balance, muscle tone, and visceral and somatic reflex activity
Food cooking is an example of an endothermic reaction, because removing the source of heat would cause the reactions to stop
Answer: Option D
<u>Explanation:</u>
Cooking food is an example of endothermic or the heat-absorbing reaction where heat is absorbed by the system from the surrounding. Food is cooked by absorbing heat from the surroundings. Hence the temperature of the surrounding decreases.
Now when the source of heat is removed that would cause the reactions to stop. In an endothermic reaction an external heat is required for the reaction to proceed. Hence when the heat is removed and as the product is not that stable it is liable to stop the reaction.
Answer:
D Copper is transported by the stem from the roots to the flowers, where it affects reproductive tissues.
Explanation:
Answer:
option c punctuated equilibrium
Explanation:
Punctuated equilibrium occurs in a process whereby evolutionary changes occurs in some organisms in a rapid burst of time rather the conceived gradual changes that occurs over a long period of time. this burst of time might be in about 500,000 years. It is assumed that the organism has maintained/lives in stasis for a long period without a need for change, but then, once the change takes place (most of the time, due to an environmental factor), the organism quickly adapts to its new environment with this new adaptation.
I would say that answer choice C is the best out of this selection. Carbon is the main element in organic compounds, and organic compounds just so happen to make up the cells that carry out life processes for all living things. Hope this helps.
