Among Sponges and Cnidarians, the difference among given facts is in "Have a network of nerve cells".

Explanation:

Both Sponges and Cnidarians have pores, they reproduce by buddings, and they live in freshwater. The major difference in both organisms is that: cnidarians have very simple nervous system made of sensory nerves that are arranged in the form of neural network. On the other hand, sponges are simple multicellular organisms without any neural network at all. In fact, they are the only multicellular organisms (animals) without a nervous system.

What if plants AND humans needed photosynthesis to live?

hoa [83]

Answer:

Just 5% to 10% of the sunlight they receive gets converted into energy. So if humans are going to photosynthesize, we'd better get good at it. We would probably evolve to become a lot bigger to absorb enough light to feed and grow.

<h3>1.<u> Answer;</u></h3>

A. lipid

<h3><u>Explanation;</u></h3>

<u><em>Lipids are among the four biomolecules, others being nucleic acids, carbohydrates, and proteins.</em></u>

<h3>2. <u>Answer;</u></h3>

B. The cell membrane contains cholesterol molecules.

<h3><u>Explanation;</u></h3>

<em><u>The structure of the lipid bi-layer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.</u></em>
<u><em>Carbon dioxide and oxygen are molecules that can move across the lipid bi-layer without the help from membrane proteins or integral proteins. They are non-polar molecules and thus can easily pass through the hydrophobic interior of a membrane.</em></u>
