The rocks would be younger the closer you get to the ridge
The Mid-Atlantic ridge is a divergent tectonic boundary in the middle of Atlantic Ocean spanning north to south.
Explanation:
At a divergent boundary, a phenomenon called seafloor spreading occurs as new crust is formed along the ridge. New crust seems to 'spread' from the ridge. Therefore, the farther away from the ridge you get, the older the crust gets. This occurs because magma from the mantle rises to replace the void created by the tectonic plates moving away. The magma rises and cools creating a mountainous ridge long the boundary. Seafloor spreading, however, happens really slowly and the changes are only perceptible over 1000s and millions of years.

Here, given-
homozygous alleles 'a' have a frequency of 0.3.
Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.
The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.
Calculation-
Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-
Thus, the individuals homozygous for the allele can be calculated by

Answer:
Water bath is used maintain temperature.
Explanation:
Water bath is laboratory container (equipment) filled with heated water and is used in conducting experiments that requires the maintainance of a certain temperature.
Digestive enzymes usually perform their functions at temperature of 37°C (optimal temperature) and they will need the use of water bath to maintain it. The body ranges at this temperature, thus 37°C will affect the activity of enzymes found in digestive tract. They will be more active in catalyzing the digestion reaction of carbohydrates and fats as this is their optimal temperature in the body.
