Because they are built with overlapping sand and they can break easily.
Answer:
Circulation and Digestion
The muscular system and the circulatory system work with the small intestine. The muscular system helps the small intestine break down food. The circulatory system works with the small intestine and gets nutrients to the rest of the body.
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.
The answer for the question above is the last option. The evidence from <span>the Arctic that shows the ocean has a significant influence on climate change is that, ice </span><span>reflects heat from the sun and open water absorbs it. Hope this answers your question. Have a great day!</span>
I like to make flash cards and have someone else help with answering. Write a question on one side and the answer on the other, and you can even do it yourself.
