You should test your hypothesis.
Answer:
<u>c. Sucrose and glucose</u>
Explanation:
The paramecium is a large, single-celled microbes, surrounded by a plasma membrane. Simple diffusion occurs in cells across plasma membranes, as a form of passive transport. In diffusion, solutes move from regions of high concentration to regions of low concentration across the plasma membrane.
Here, the internal environment has higher concentrations of sucrose and glucose, but lower concentrations of fructose, thus the solutes will move along their concentration gradient, to where the concentrations are lower. In order for the fructose molecules to move out of the cell, the molecules have to move against their concentration gradient - a process requiring energy known as active transport.
Answer:
B
Explanation:
It removes other waste from our body and keeps our blood clean
Spongy bone has trabecular which serve as reinforcing plates against a force. The loss of spongy bones causes weakening of the internal support that the compact bone requires and the entire bone breaks.
B) Embryonic stem cells research requires the use of human embryos.
