Answer:
Research Hypothesis : 'Age predicts memory performance' is ALTERNATE HYPOTHESIS
Explanation:
Hypothesis is a rational proposition , tested for its truth validity. It is usually used to test the relationship between two variables
Null Hypothesis is a neutral hypothesis of no difference, stating no relationship between the studied variables.
Alternate Hypothesis is an effect based hypothesis , stating relationship between the studied variables.
Example : Given Case - Studying age relationship with memory ; implies following hypothesis
- Null Hypothesis = Age doesn't predict memory performance
- Alternate Hypothesis = Age does predict memory performance.
The archaeological evidence found in Mesoamerica sites of Tenochitlan and Machu Picchu suggests that at these societies we’re highly advanced and developed societies.
Evidence of complex social structure, planned city layouts, markets, public buildings, and agricultural planning have been found at these sites.
<span>Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72 degrees</span>
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.
