Answer:
B.
Explanation:
They weren't allowed to vote until 1970
Answer: First, hunter-gatherers enjoyed a varied diet, while early farmers obtained most of their food from one or a few starchy crops. ... Second, because of dependence on a limited number of crops, farmers ran the risk of starvation if one crop failed.
Farming meant that people did not need to travel to find food. Instead, they began to live in settled communities, and grew crops or raised animals on nearby land. They built stronger, more permanent homes and surrounded their settlements with walls to protect themselves.
Answer:
Contract system
Explanation:
A contract system is used by many organizations in written form between two firms to an agreement to be carried out in the definition of work. In the context, according to the contract system, the private law firms are called for bidding for a fixed payment and for a specific period.
Thus he answer is --
Contract system.
The agarose gel's mesh-like structure allows for DNA separation. Larger DNA pieces become stuck and move slowly through the pores, but smaller fragments can pass through the pores quickly.
<h3>What connection exists between the DNA's size and the agar gel's structure?</h3>
Because DNA molecules have a constant mass/charge ratio, they are separated by size in an agarose gel in a way that the distance they travel is inversely correlated to their molecular weight (3).
<h3>What connection exists between the DNA fragments' size and gel electrophoresis appearance?</h3>
The negatively charged nature of DNA causes it to move toward the positively charged electrode when an electric current is supplied to the gel. Because shorter DNA strands pass through the gel more quickly than longer strands, the fragments are organized according to size.
<h3>What connection exists between the size of a DNA molecule and its rate of gel migration?</h3>
DNA fragments are separated based on molecular weight using agarose gel electrophoresis. The distance travelled on the gel correlates inversely with the logarithm of the molecular weight, with smaller fragments migrating quicker than larger ones.
