<span>Mutation cannot be predicted and research cannot determine when mutations will occur. However, natural selection indicates that species with the strongest traits will multiply more and live longer than their weaker counterparts. Therefore natural selection is systematic and predictable.</span>

Which examples describe how a plant might meet the challenge of getting and using energy? Choose all answers that are correct. A
SpyIntel [72]
<span>Assume: Energy = Sunlight.

grow lamps, etc.

A is definitely correct: Plants and trees that need maximum light MUST be able to grow as tall or taller than the other plants/trees around them. Plants that are more efficient at producing food (through photosynthesis) can live in the shadows of other plants. B doesnt involve getting or using energy. C is the function of food storage. The Energy was used to make the carbohydrates up in the leaves. D This should read New Leaves on the tree... If the tree was not deciduous, the leaves would stay on the tree and continue to perform photosynthesis throughout the year - as long as there was ample light. A is definitely correct and D is probably a correct answer also. FYI - Photosynthesis takes water from the plant, CO2 from the air and Energy from the Sunlight. Chloroplasts (the Green in the green leaves and stems) combine the molecules and light energy to produce 3 byproducts: O2, H2O, and Carbohydrates (mainly sugar or C12H22O11). The carbohydrates are then transported by the plants capillary system (by means of the Phloem which flows down to the roots) to the roots where it is converted as needed to be stored as some form of sugar or starch for use later in plant growth (leaves, stems and roots).</span>

1) Amino acids. Option B.

2) Phosphorus. Option D.

<h3>What are proteins?</h3>

Proteins are macromolecules made up of 2 or more amino acid units linked together by peptide bonds.

According to the passage, antibiotics work by breaking down the cell water proteins of bacteria. When proteins are broken down, they are broken into their component amino acids.

Therefore, when the researchers examine the phagocyte, the presence of amino acids would be an indication of the effectiveness of the antibiotics.

Amino acids are made up of elements such as nitrogen, carbon, oxygen, and hydrogen. Thus, if the researchers examine the monomers present in the phagocytes, all these elements should be found. Except for phosphorus.
