Answer:
This question is incomplete as it lacks options, however, it will be answered BROADLY so the it can be understood enough to select the correct answer.
Please find the explanation below
Explanation:
Cells perform different functions and look differently because of the process of CELL DIFFERENTIATION. All cells arise from a single stem cell, which then gradually differentiates into different types of cells with different functions, as they divide.
At the molecular level, these different types of cells contain the same DNA sequence as rightly stated in the question. However, they look and perform differently because some of the genes are turned on while the others are turned off via the process of GENE EXPRESSION.
Therefore, a blood cell and skin cell possess exactly the same DNA sequence but look different and perform different functions because of CELL DIFFERENTIATION in which some genes on the DNA sequence are expressed and others are repressed. For example, in the blood cell; the genes coding for certain proteins found in blood are expressed while every other gene is silenced or inhibited. This allows those cells to perform only blood-related functions.

It inhabitants the deep waters off the coasts of mainland Australia,Tasmania as well as the waters of New Zealand.
The answer is c. Deciduous trees lose their leaves to prevent nutrient and water loss.
Losing leaves is a trees' strategy to survive cold winters. It is known that trees primarily lose water through leaves. In the winter, there is no enough water to replace that lost water. If the trees were not to throw away their leaves, they will soon dry out. Also, before falling the leaves begin, reabsorb all nutrients from the leaves and store it for the cold winter. Thus, losing leaves is important to prevent both nutrient and water loss during the winter.
