Johnny's teacher asked him to explain how to make a wet-mount slide to the rest of the class. Here is Johnny's response: "Well
, you start by putting a few drops of water on a clean slide. Once you have obtained your specimen, you carefully place your specimen down on the drops of water on top of the slide at a 45 degree angle. You add a few more drops of water, then lower the cover slip over the specimen."
Was Johnny's description correct?
A. No, you don't need to add water to the slide after adding the specimen.
B. No, he forgot to heat up the water before adding it to the slide.
C. Yes, he did not make any mistakes.
D. No, the cover slip needs to be lowered at a 45 degree angle, not the specimen.
The correct answer is letter a, it is because in wet drop method, it does not need to add water after placing the specimen because adding water before placing the specimen in the glass slide is already enough and after placing the specimen, a cover slip is the last step in finishing the method. That is why Johnny is not correct in doing the procedure.
Trees reduce the rate of erosion by: protecting the soil from the impact of rain. transpiring large amounts of water, which counteracts very wet soil. binding soil to sloping land with their roots
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template. Meanwhile, mRNA is comparable to a copy from a reference book because it carries the same information as DNA but is not used for long-term storage and can freely exit the nucleus. Although the mRNA contains the same information, it is not an identical copy of the DNA segment, because its sequence is complementary to the DNA template.
