Answer:
B) neurons have stable, relatively unchanging internal environments.
Explanation:
Rough endoplasmic reticulum (RER) is studded with ribosomes which in turn serve as the site for protein synthesis. A cell with an extensive network of rough endoplasmic reticulum has higher rates of protein synthesis. Mitochondria are the powerhouse of cells and serve as the site for aerobic cellular respiration. A large number of ATP molecules are produced in mitochondria. Therefore, a cell with relatively many mitochondria appears to have a higher demand for ATP and higher consumption of oxygen.
A cell with higher rates of consumption of ATP and protein synthesis should be functionally active. The charge across the membrane and the internal concentration of ions such as Na+, K+ of a neuron keep on changing during the conduction of nerve impulse. Therefore, the presence of many mitochondria and RER does not indicate that the neurons maintain relatively constant internal conditions.
Assuming that I know the rest of this question already the answer is Haploid number of 6
Answer:
the number after 1:the process of photosynthesis is energy realising because the process converts light energy into free into free energy that can be used for cell functions
Explanation:
in has some explanations about photosynthesis
The chloroplast for carbohydrates, motchondria and the ribosomes for protein is responsible for the production of the new molecules within a cell
The cells utilize energy in the form of ATP (Adenosine triphosphate). This ATP cannot be directly derived from the food we eat by the cell in able to perform their functions. This food is broken down into smaller components, and glucose is formed from it. This glucose is used as the starting molecule of the electron transport chain, which produces ATP as a end product. This ATP is then used by the cells to perform their functions.
