The nervous system conserves energy, while the sympathetic nervous system consumes energy.
<h3>What is the nervous system?</h3>
The nervous system is an organ system that coordinates the activities of muscles, monitors organs, constructs and processes data received from the senses and initiates actions.
The nervous system can either be the following;
- Sympathetic
- Parasympathetic
The sympathetic nervous system is a part of the autonomic nervous system that raises blood pressure and heart rate, constricts blood vessels, and dilates the pupils when under stress.
On the other hand, the parasympathetic nervous system is one of the divisions of the autonomic nervous system, based between the brain and the spinal cord, that slows the heart and relaxes muscles.
This suggests that the parasympathetic nervous system conserves energy because it slows the heart while the sympathetic nervous system consumes energy.

Answer:
Convergent evolution created all of these flying species.
<h2>Sea star </h2>
Explanation:
In the given example sea star played the role of keystone species
- Robert Paine actually coined the term keystone species to describe the effect that the sea stars had on biodiversity in this community
- Keystone species are those species which are least abundant but play a governing role to decide the structure and function of community
- Loss of keystone species in a community can lead to disturbance in structure and function of a community and it cannot be recovered by other species
Answer:
The correct answer would be His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane.
In cellular respiration, glycolysis takes place in the cytoplasm of the cell and converts glucose into 2 molecules of pyruvate. Pyruvate is then transported into the mitochondria for further oxidation.
It is transported into the mitochondria with the help of transport protein pyruvate translocase where it is decorboxylated to produce acetyl-CoA. This acetyl-CoA then enters the Krebs cycle to produce ATP (adenosine triphosphate) with the help of oxidative phosphorylation, electron transport chain and chemiosmosis.
In absence of this transport protein, the cell can not completely oxidize the glucose or carbohydrate. It switches to the metabolism of fats and amino acids in order to meet the energy demands of the cell.
Close friend and supporter of Charles Darwin especially in his theory of evolution. 1868 examined samples of mud recovered from the deep-sea floor 11 years back to discover a surface layer of thick mucus-like material with small embedded particles on the samples. Bathybius haeckeliiafter famous naturalist Ernst Haeckel Subdivisions looked to move so he assumed they were a form of living protoplasm and he named the "organism".
