<em>Explanation:</em>
<em> A). in the reaction that creates acetyl CoA (coenzyme A)</em>
The correct answer is Phloem
Explanation:
Phloem is a transport tissue of vascular plants. It is used for transport of food and nutrients, so sugar is definitively brought by phloem.Other choices cannot be right because collenchyma and parenchyma are ground tissues, while xylem is the carrier tissue similar to phloem but worked for a conveyor of water and minerals.
Answer:
Proteins can be catalysts which help to reduce the energy used in a chemical reaction or speed it up. Proteins can help carry oxygen throughout the body in the form of hemoglobin
Explanation:
The answer is B because:
Cell walls are made of cellulose and proteins (hence II).
Animal cells don't have cell walls (only cell membrane) but plant cells do so IV
They must be semipermeable since materials for example carbon dioxide and water for photosynthesis have to go into the cell <em>some</em> way.
