Answer:

Climate and slavery

Explanation: Slaves were the main reason that there was food before the end when Abraham was president. Climate and slavery can change how the crops were grown. I'd also say the geography was messed up then due to the climate. (sorry if wrong Q-Q)

Answer:

The climate on the plains was too arid.  160 acres was not enough land to make a living.  The lack of natural vegetation made raising livestock difficult.

Based on the information in the table, which of the following changes is least likely to produce a phenotypic
yaroslaw [1]

GAU to GAC​ is least likely to change phenotype of an organism.

<h3><u>Explanation</u>:</h3>

Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.

Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.

Both the GAU and  GAC​ codes for aspartic acid. So the phenotype won't be affected much by this mutation

1) a) In ONE sentence only, how is telomerase activity different from DNA polymerase activity during DNA elongation? b) In ONE s
Ipatiy [6.2K]
1. During DNA elongation, polymerase enzyme adds new, free nucleotides to the three prime end of the newly forming strand, elongating it in  five prime to three prime direction while the telomerase protects the important genes at the end of the chromosome from been deleted as the DNA strand shorten during DNA elongation.

2. During DNA elongation, helicase enzyme separates the double stranded DNA  into single strand by melting the hydrogen bond that holds the DNA molecule together thus enabling each strand to be copied while the telomerase acts by preventing the telomere from been deleted during elongation.
