Sloan [31]3 years ago

whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

Answer:

Below:

Explanation:

Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Why are standards of mass necessary?
Alex_Xolod [135]
Hello!

Standards of mass are necessary because it is a whole lot easier than using a bunch of different systems. Since the metric system is common, it would be easier to compare something with someone from America and someone from Germany using the metric system as opposed to something otherwise.<span />

A group conducted a survey of two different plots on campus. Both plots had 100 trees in them. Plot 1 had 85 maples, 5 birch, 5
nirvana33 [79]

Answer:

d. The species diversity of plot 2 is greater than that of plot 1.

Explanation:

Species diversity of an area depends on its species richness and species evenness. Species richness is the number of species present in that area. Species evenness measures how evenly these species are distributed.

Here, both plot 1 and plot 2 have same number of species. They both have four species of trees ( maple, birch, oak and pine) hence their species richness is same. However plot 1 has 85% maple trees and the rest three species make the remaining 15%. Plot 2 has more even distribution as 35% of trees are maple trees and birch and oak also have similar frequency with 25% and 35% respectively. Hence, plot 2 has more evenness.

Species diversity depends on both richness and evenness. Since plot 1 and 2 have same richness but plot 2 has more evenness, plot 2 has more species diversity than plot 1.

You are doing research in bacteria on the effects of mutating the shine-dalgarno sequence. you change some nucleotides in the sh
padilas [110]
<span>Shine-Dalgarno sequence is a sequence that precedes the starting codon in the mRNA. the small sub-unity of ribosome will recognize it with by a specific sequence in the initiation phase of translation.

The best way to restore the translation speed if the Shine Dalgarno sequence is mutated is to make a change in the small sub-unity of the ribosome, specifically in the RNA sequence that recognizes the mRNA Shine Dalgarno sequence, so it can be recognized again. and the translation process will be restored.
</span>Another way to improve a translation speed if to provoke a mutation in the proteins' genes involved in the translation process (like enzymes and translation factors), there will be a chance to increase their effectiveness, especially for enzymes, so the translation speed will be improved.
