A doctoral student is studying the genetic makeup of a species of jellyfish that occurs at low, middle, and high latitude regions of the Pacific Ocean. On an
oceanographic expedition, she collects specimens of the jellyfish throughout its range Upon returning to the laboratory at the university, an assistant places all of the
Jellyfish in an aquarium with an average temperature of approximately 20'C. After a few days, he notes that almost two-thirds of the jellyfish have died. Using the figure
below, how would you explain which jellyfish likely make up the bulk of the survivors and what the mistake was?
A. The survivors were likely collected from the dark gray areas on the map. those from other regions could not adapt
B. The survivors were likely collected from the light gray areas on the map those from other regions could not adapt.
C. The survivors were likely from the black areas of the map but had the most advantageous genes of those collected.
D. The survivors were likely from the black areas of the map but adapted to the difference in temperature in the laboratory.
Answers
The survivors were likely collected from the light gray areas on the map those from other regions could not adapt. That is option B
The effect of temperature change on organismsThere are some organisms such as plants and animals that are capable of changing and adjusting to different environmental conditions.
Aquatic animals such as jellyfish can adapt to warmer ocean waters, but not necessarily to extreme heat or extreme cold weather. That is, it can survive the temperature of 12 - 24°C as indicated in the figure.
But some species of jellyfish that has adapted in extreme cold and extreme hot weather, may find it difficult to abruptly adapt to an average weather.
Therefore when placed in the 20°C aquarium, they couldn't survive because of the temperature of the new environment.

Answers
The ultimate purpose of mimicry is all the above. So, the correct option is D.
What do you mean by Mimicry?
Mimicry may be defined as the resemblance of a species (mimic) to another original species (model).
Mimicry provides secure protection from predators, it allows the predators to come closer to their prey, it also allows an animal to fit in with a different species for the purpose of protection (prey), and hunting (predators).

A low water concentration means a
solute concentration
high
low
Answers
Answer:yes
Explanation: when the concentration of a solute is high, the concentration of water is lowered since there is more solute per water, less water per solute. Thus, when water moves from low concentrations of solute to high concentrations of solute, it moves from high concentrations of water to low concentrations of water.
Answer:
high
Explanation:
If the concentration of the water is low ten that means the solute-solvent ratio is high which means the solute(solid dissolved) is high

Based on study of Finches in the Galapagos islands, finches with beaks sizes better suited to their environment survived while those not suited died in a process of natural selection.
