Answer:
Molecule 3
Explanation:
DNA contains Deoxyribose, Phosphate, and 4 bases: Adenine(A), Thymine(T), Guanine(G), and Cytosine(C)
Molecule three contains Deoxyribose, Phosphate, and Guanine, while the others do not.
RNA contains ribose, which is why Molecule 2 is out of the question.
DNA does not contain glucose, henceforth marking Molecule 1 incorrect.
Molecule 4 may seem correct, but recall that DNA contains Deoxyribose, Phosphate, and a base, in this case Guanine(G). This answer contains no Deoxyribose.
<em>Answer:</em>
<em>Photosynthetic cells contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose.</em>
Loss of ability to perform skilled motor activities such as piano playing, with no paralysis or weakness in specific muscles, might suggest damage to the premotor cortex.
The premotor cortex is part of motor cortex situated in front of the primary motor cortex in the brain. The premotor cortex directly controls behavior by preparing the trunk muscles of the body. The primary role of the premotor cortex is to use information provided by the senses in controlling movements, to understand the actions of others, and to use ideal rules to carry out certain tasks. Different parts of the premotor cortex have various features and they emphasize distinct functions.

where are options please....
The biosynthesis of fatty acids and lipids meets two imperatives in the
cell :
- supply of fatty acids necessary for the synthesis of structural lipids;
- storage of energy.
The synthesis of fatty acids goes through a dehydration step during its synthesis. and its catabolism goes through a hydration stage, which shows the importance of H2O molecules to build lipids (even cholesterol).
Synthesis of the fatty acid:
firstly, acetyl-ACP and malonyl-ACP were condensed, followed by reduction of acetoacetyl-ACP to β-hydroxybutyryl-ACP, followed by dehydration of β-hydroxyacyl-ACP, and finally reduction of the double bond by NADPH + H
Catabolism:
The reverse steps will occur: a beta oxidation, a hydration of the molecule, and finally another oxidation.
