A Personal Experience Timeline helps the writer generate a topic. The writer can use the timeline to see specific moments in their lifetime. The correct answer will be A.
I will think it’s B.... hope it helps!
Yes because they are helpful to the earth
Answer:
The elemental is required in very small amount. (Ans. A)
Explanation:
Trace element is also known as micro-nutrient. It is also defined as any chemical element required by living organisms in a minute or small amounts which is usually part of the vital enzyme (cells produced by catalytic protein).
Exact needs of trace elements vary among species, like commonly required plant trace elements are cooper, zinc, manganese, boron, and molybdenum. Animals commonly required iodine, manganese, and cobalt.
Absence of necessary plant trace elements required by plants in the soil causes deficiency disease, lack of animal trace elements used by animals in the soil may not harm plants, but, animals feeding on those plants develop their deficiency disease.
So, the adjective trace means that the elemental is required in a very small amount.
Answer:
B. The mutation results in a new, dominant allele
C. The mutation occurs in a gene that controls development and alters differentiation of a cell type during development.
D. The mutation occurs in a codon and alters the function of the final protein
Explanation:
All the above things will change the <u>ultimate expression</u> or phenotype by altering the proteins. Choices B, C, and D will all change the outer functioning.
Choice A only affects the rate of transcription, so it may go faster or slower, but the end product will be the same.
This part that doesn't look like it's one of the choices ("The mutation occurs in a portion of an intron not responsible for exon splicing.") would not affect phenotype, because introns are removed before the RNA is sent out.
Choice E says that the amino acid sequence is unchanged, meaning the protein final product will be the same and the expression will not change.
