Summary Introduction

Introduction:

The cell is a functional and structural unit of all living organisms and makes the basic building block of the body. Each type of cell performs specific functions such as disposal of the waste product, maintenance of shape and integrity of the cell, and obtaining nutrient from its surrounding fluids.

Answer to Problem 1DYKB

Correct answer:

The obtaining of the nutrients and chemical building blocks, maintaining the integrity of the plasma membrane, and disposing of waste, are the general functions performed by the cell. Therefore, option c. is correct.

Explanation of Solution

Reason for the correct statement:

Option c. is given as “replacing cells through cell division”. Some cells divide frequently such as epithelium cell of the intestine and an outer layer of skin, but most of the cells do not divide after maturation and specialization, such as muscle cells, nerve cells, and red blood cells. Hence, all the cells do not replace through cell division.

Hence, option c. is correct.

Reasons for incorrect statements:

Option a. is given as “obtaining nutrients and chemical building blocks”. Cells obtain their nutrients from the surrounding in order to complete metabolism and energy formation. Hence, option a. is incorrect.

Option b. is given as “maintaining the integrity of the plasma membrane”. Plasma membrane supports the cell in maintaining the framework and shape of the cell. Hence, option b. is incorrect.

Option d. is given as “disposing of waste”. Accumulation of waste products interfere with the normal functioning of the cell, and they are disposed of by the cell. Hence, option d. is incorrect.

Hence, options a., b., and d. are incorrect.

Conclusion

Cell replacement through cell division is not performed by adult and specialized cells.

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
