Use the data and what you have learned about evolution to explain how mutation is a random process, but natural selection is not random.

Answers

The data are not found here, but evolution means 'descendence with modification', which may occur due to natural selection and mutations.

What is evolution?

Evolution is descendence with modification, which generally is caused by a process called natural selection.

Natural selection 'selects' the most adaptive variants in the population, which occurs due to the emergence of mutations.

A mutation is any genetic change in the nucleotide sequence of the genome of an individual.

C Jurassic
d Paleozoic

Answers

Answer:

D.

Explanation:

Paleozoic is not one of the 3 major periods of the Mesozoic Era

Hope that helps!

From 252 to 201 million years ago was the Triassic Period. Between 201 and 145 million years ago is the Jurassic Period. Between 145 and 66 million years ago was the Cretaceous Period, hence option D is correct.

What is the Mesozoic Era?

54 million years of the Mesozoic Era, or 199.6 to 145.5 million years ago, are referred to as the Jurassic Period.

The Jurassic Period, so named after the Jura Mountains in France and Switzerland, where rocks from this era were first investigated, has gained widespread recognition.

The Cretaceous is the final part of the Mesozoic Era, lasting from 145.5 million years ago to 65.5 million years ago, and is characterized by the demise of the dinosaurs (except birds).

Therefore, the Paleozoic is not a period of the Mesozoic Era, hence option D is correct.

what is the uses of enter key​

Answers

Answer:

the uses of enter key is to enter a question or look up things and sometime to play computer games hope this helps. :)

Explanation:

Answer:

Also called the "Return key," it is the keyboard key that is pressed to signal the computer to input the line of data or the command that has just been typed.

It Was the Return Key

The Enter key was originally the "Return key" on a typewriter, which caused the carriage to return to the beginning of the next line on the paper. In a word processing or text editing application, pressing Enter ends a paragraph. A character code for return/end-of-line, which is different in Windows than it is in the Mac, Linux or Unix, is inserted into the text at that point. See CR/LF.

The DNA in a strain of E. coli contains 32 % adenine. What percentage of DNA is cytosine

Answers

Answer:

The DNA of E. coli contains 19,120 6-methyladenines and 12,045 5-methylcytosines in addition to the four regular bases and these are formed by the postreplicative action of three DNA methyltransferases. The majority of the methylated bases are formed by the Dam and Dcm methyltransferases encoded by the dam (DNA adenine methyltransferase) and dcm (DNA cytosine methyltransferase) genes. Although not essential, Dam methylation is important for strand discrimination during repair of replication errors, controlling the frequency of initiation of chromosome replication at oriC, and regulation of transcription initiation at promoters containing GATC sequences. In contrast, there is no known function for Dcm methylation although Dcm recognition sites constitute sequence motifs for Very Short Patch repair of T/G base mismatches. In certain bacteria (e.g., Vibrio cholerae, Caulobacter crescentus) adenine methylation is essential and in C. crescentus, it is important for temporal gene expression which, in turn, is required for coordinating chromosome initiation, replication and division. In practical terms, Dam and Dcm methylation can inhibit restriction enzyme cleavage; decrease transformation frequency in certain bacteria; decrease the stability of short direct repeats; are necessary for site-directed mutagenesis; and to probe eukaryotic structure and function.Explanation:
