Chloe is developing a model of photosynthesis. The first part of the model is shown below. Which would be the MOST useful next step for Chloe to develop the photosynthesis model further? A.) Extend the lines for sunlight so that they pass through the autotroph.
B.)Represent a chemical reaction in the autotroph that produces high-energy carbohydrates.
C.)Represent a chemical reaction in the autotroph that produces high-energy proteins.
D.)Draw a circle to represent a heterotroph, and draw a line to connect it to the autotroph.

B, because logically, Photosynthesis takes sunlight (light energy), water(h20), and carbon dioxide( c02), and converts it into sugars (glucose / carbohydrates), and oxygen(o2). As D would be less necessary because humans and animals are not autotrophs and do not undergo photosynthesis to produce their own food. it is not the most necessary thing to label.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
