Correct answer - C I abs III only.

Why? - DNA contains the instructions needed for an organism to develop, survive and reproduce. Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. ... When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain.

Answer:

D) The lac operon will function normally.

Explanation:

  • The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream.

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>
