What's the main reason why cell specialization is important?

Question 12 options:

It allows multicellular organisms to perform many distinct functions.


It allows unicellular organisms to perform many distinct functions.


It generates totipotent cells.


It creates cells at a faster rate.

Answer:

It allows multicellular organisms to perform many distinct functions.

Explanation:

Cell specialization is important primarily because it allows multicellular organisms to perform many distinct functions. Cell specialization isn’t important in unicellular organisms, because it doesn’t occur. Cell specialization isn’t important primarily for creating cells faster, and it doesn’t generate totipotent cells. Rather, totipotent cells are the stem cell progenitors that allow cell specialization to occur.

It makes it possible for multicellular creatures to carry out a wide variety of unique roles. Therefore, option (A) is correct.

The transformation of a stem cell into a differentiated cell type is accomplished by a process known as cellular differentiation. Typically, the cell will transform into a type that is more specialized.

The primary reason why cellular specialization is so important is that it enables multicellular organisms to carry out a wide variety of diverse jobs. Because it does not take place in unicellular creatures, the process of cell specialization is irrelevant to their biology. The primary reason why cell specialization is not crucial is that it does not produce totipotent cells, nor does it speed up the process of making new cells. Instead, totipotent cells are the progenitors of stem cells, which are the cells that can differentiate into specialized cell types.

On April 20, 2010, an explosion on the Deepwater Horizon Macondo oil well drilling platform released 4 million barrels (636,000 cubic meters) of oil into the Gulf of Mexico. It took scientists and engineers nearly three months and several different attempts to cap the well. The Macondo oil well was located 1524 m (5000 feet) below the surface of the water, about 80 km (50 miles) off the coast of Louisiana. The spill affected 2113 km (1300 miles) of shoreline along the coasts of five states. Most crude oil contains 84–87% carbon by weight. Scientists have not yet fully assessed the environmental impact of the accident.

Computer modeling can be used to help improve cleanup and response systems for the next major oil spill. Which of these uses demonstrates how computer modeling can be used to minimize the impact of another spill?
a
Creating a model of how the oil spread through the Gulf of Mexico to predict what areas need the greatest amount of protection.
b
Calculating the total oil that entered the Gulf of Mexico during the spill.
c
Recording the number and type of each dead organism collected during the spill.
d
Finding the average flow rate of the oil through the burst pipeline during the spill.
