Answer:

The concentration of sugar on the left side of the beaker would reduce while there will be no sugar on the left hand side.

Explanation:

<u>The concentration of sugar on the left hand side of the beaker would reduce and the water level increased while the water level on the right hand side of the beaker would reduce with zero sugar concentration.</u>

<em>Only water molecules are able to move osmotically through a selectively permeable membrane. Water molecules move from the region of low water potential corresponding to the region with no sugar to the region of high water potential corresponding to the region with sugar.</em>

Hence, the concentration of sugar on the left hand side of the beaker becomes diluted as more water moves into it from the right hand side of the beaker through the selectively permeable membrane. Meanwhile. the right hand side remains without sugar but with lower level of water.

Which of the following is an example of parasitism
Len [333]

Answer:

A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, and barnacles. The fleas, in turn, get food and a warm home.

Dude why is bio so hard please help lol
Evgesh-ka [11]

Answer:

1.Sugar bonds

2.Transport proteins

3. Digestion

4. Oxidation

explanation

Chemical energy is stored in the bonds of sugar.

The concentration gradient of a substance across the membrane represents potential energy bcz it drives diffusion.Transport proteins aids the diffusion.

Digestion converts chemical energy into kinetic energy used by cells.

When the electrons are destroyed in the glucose,Energy contained in the bonds is released in small bursts,some of it is captured in the form of ATP .'The electrons are transferred to smaller molecules known as electron carriers.The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion,called the electron transport chain.As electrons move through the electron transport chain they go from a higher to lower energy level and are finally passed to Oxygen to form water.The energy released is captured as a proton gradient which powers the production of ATP.

Not 100% sure whether it's the correct answer but the concept is true 100% btw I stand to be corrected
