It is believed that a less massive star will age more slowly than a more massive star, despite the fact that massive stars have much more fuel. The reason that a more massive star will burn out quicker is because it takes a significant more amount of energy to keep the star burning due to the increased diameter of the star compared to the less massive star. A less massive star will use its fuel less quickly due to being smaller and having less mass to fuel.
The massive star burns its fuel at a greater rate than the less massive star.
Answer:
b, d, and f
Explanation:
The transition from aquatic lifestyle to land posses some problems to plants; these include;
- <em>Water conduction and food distribution problem</em>
- <em>Desiccation problem</em>
In order to firmly establish in the terrestrial environment, <u>plants need to be able to obtain the water necessary for their metabolic activities and be able to distribute manufactured food from the various sources of production to other parts of the plant body.</u> This is overcome by the development of conducting tissues in the form of phloem and xylem. The xylem is used to conduct water from the root to the body of the plant while the phloem is a tissue used to conduct manufactured food from the point of manufacturing round the necessary parts of the plant.
<u>Plants also face the problem of heat and the risk of desiccation on land</u>. The development of waxy cuticle takes care of this problem. The waxy cuticle acts as an insulator on leaves and other organs of the plant and thus protect them from desiccation.
Correct options: b, d, and f
Answer:
A mutation during protein synthesis may not affect the protein since the mutation causes a new code for the same amino acid, the protein will still function normally.
Explanation:
Protein synthesis depends on the transcription of DNA to RNA, and on the sequence of nucleotides in the chain, determining the triplets or codons that encode a specific amino acid.
In protein synthesis, when a mutation alters the codon, changing one nucleotide for another, it is possible that the mutation does not alter the amino acid and the protein functions correctly. This is because an amino acid can be encoded by several codons, as occurs with leucine, which is encoded by CUU, CUC, CUA and CUG.
<em> The other options are not correct because one mutation does not give better amino acids or more powerful proteins.</em>

The right answer for the question that is being asked and shown above is that: "b. the act<span>ual yield may be different from the theoretical yield because reactions do no always go to completion." This is the statement that is not true about "yield."
