To focus a magnifier using the high-energy lens you haveto use the main focus adjustment knob however take care as a result of if youcrank down too hard, you'll be able to harm the magnifier and therefore the slide.

  • Fine Adjustment Knob - This knob is within the coarse adjustment knob and is employed to bring the specimen into sharp focus underneath low power and is employed for all focusing once using high power lenses.

You don't wish to wreck the slide. therefore you ought to forever look on the aspect of the magnifier therefore you do not break it and use fin adjustment knob only.

Hope it helps!

A mutation in a polypeptide with the original amino acid sequence of: Met-Ala-Gln-Arg-Glu-Leu results in a mutant with the seque
Nezavi [6.7K]

Answer:

This question lacks options, however, it can be answered based on general understanding of the topic

The answer is SUBSTITUTION MUTATION

Explanation:

A mutation is any change that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. One type of mutation is SUBSTITUTION MUTATION, which is a mutation in which one or more nucleotide base is replaced by another in the sequence.

Nucleotide bases are read in a group of three called CODON. Each of these codons specify amino acid. Hence, if the nucleotide base sequence is altered during mutation, the amino acid sequence is altered likewise. In this case where the original amino acid sequence is: Met-Ala-Gln-Arg-Glu-Leu, the mutation affected the nucleotide bases coding for Arginine (Arg), hence changing it to Glycine (Gly).

This means that a base substitution mutation occured, replacing the amino acid Arginine with Glycine in the mutated sequence.

Why did artificial selection interest darwin?
Vedmedyk [2.9K]
<span>To prove his Theory of Evolution. After studying the different species of finches he found the Galapagos Islands, Darwin focused on breeding pigeons by selecting specific traits of different individuals (this is mainly a method through which different kinds of dog breeds came about). On the basis of these studies Darwin concluded that natural selection and artificial selection acted roughly in the same way. Darwin's decision to enforce a certain trait represented, in a sense, the selective pressure which is present in a natural environment (the law of the fittest).<span>

Prokaryotic organisms have a single origin of replication, whereas eukaryotic organisms have many origins where replication occu
fenix001 [56]

Answer:

B) Prokaryotic DNA is much smaller than eukaryotic DNA.

Explanation:

In biology, one event is correlated with the other event or structure like observed in the DNA. The genetic material of a eukaryote and a prokaryote differ from the other in many ways:

1. The prokaryote possesses only one chromosome which is double-stranded and circular.

2. The eukaryotic organism exhibits more than one chromosome which is not circular.

Since the prokaryotes possess very less amount of DNA then the eukaryotes therefore during DNA replication, the DNA of prokaryote require only one origin of replication from where the replication will start.

Thus, Option-B is correct.

Why is the Regulation of gene expression so important when producing specific gene products (protein or RNA)??
dangina [55]
There are two known gene products, RNA and protein. 

The regulation of gene expression is important because in different moments of human deveopment different substances are needed and also during the stable fase of human development (adulthood) necessities are dieverse.

The regulation of gene expression is what makes cells and an tissues different and that is why it's also so important.


This question is indeed not east. Hope I suplied enough information according to your needs (there is still way more info on the subject).



Hope it helped,

Happy homework/ study/ exam!
