Molecule A contains the a. starch necessary for ribosome synthesis in the cytoplasm b. organic substance that is broken down into molecules B, C, and D c. proteins that form the ribosome in the cytoplasm d. directions for the synthesis of molecules B, C, and D

The question is incomplete as it does not have the figure which is provided in the attachment

D. directions for the synthesis of molecules B, C, and D

Explanation:

In the given question, the figure illustrates that there is a molecule present inside the nucleus which could form the different or other molecules through the ribosomes like the receptor molecules, the enzymes, and the hormones.

This shows that a single molecule A has the guidelines to form all of these other molecules through ribosomes.  The molecule A inside the nucleus which contains all the guidelines for the synthesis of different molecules is known as DNA.

Thus, the selected option is correct.

1.the evidene of the reaction

2.yes

3.yes

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
