Answer:
Neurons have stable, relatively unchanging internal environments.
Explanation:
Neurons or nerve cells is the structural and functional unit of the nervous system. Neurons consists of the dendrites, axon, cell body and different cell organelles.
The neurons have mitochondria that meets the high ATP requirement and and consume more oxygen. The network of rough endoplasmic reticulum and ribosomes produce large number of proteins in neuron. The internal environment is never stable and gets changed as the nerve impulse transmission occur through the neuron. The membrane potential of the neuron gets changed and changes its internal environment.
Thus, the correct answer is option (B).
Explanation:
In the process of photosynthesis, plants that contain chlorophyll utilize carbon dioxide and water using energy from sunlight that is absorbed by chlorophyll to make glucose + oxygen.
<h2>Answer:</h2>
The correct sequence of organelles involved in making and packaging of proteins is option C: ribosomes, endoplasmic reticulum, and Golgi complex.
<h3>Explanation:</h3>
- The protein synthesis which is the translation of mRNA is done on <u>ribosomes.</u>
- As the protein is produced then it goes for modification in the <u>endoplasmic reticulum.</u>
- After some modifications proteins are packed into vesicles for the intercellular and intracellular transport.
- This packing is done in <u>Golgi apparatus.</u>
Answer:
It could change the DNA code resulting in failures
Explanation:
Yes, because it is found and created naturally
