Question

The science that deals with the study of life processes is known as
A) Psychology
B) Physiology
C) Biochemistry
D) Morphology

Answer 1

Hint: There are certain basic vital processes which are essential for an organism to stay healthy and to maintain the proper functioning of the body’s organ systems and are necessary for survival. These basic essential activities performed by an organism are called life processes.

Complete Answer:
- Study of the characteristics and mechanisms of the human body. Cells are the basic unit of life within the human body. Approximately 100 trillion cells make up the typical human, each specially adapted to perform one or a few particular functions. 25 trillion red blood cells act to transport oxygen from the lungs to all tissues in the body.
- All cells have some basic commonalities. Oxygen reacts with carbohydrates, fat, and protein to release energy. Nutrient consumption and energy production mechanisms are similar. Nearly all cells have the ability to reproduce additional, similar cells.
- Human physiology seeks to understand the mechanisms that work to keep the human body alive and functioning, through scientific enquiry into the nature of mechanical, physical and biochemical functions of humans, their organs and the cells of which they are composed.
- The principal level of focus of physiology is at the level of organs and systems within systems. The endocrine and nervous systems play major roles in the reception and transmission of signals that integrate function in animals.

Therefore from the above explanation, the correct option is C).

Note: Plant physiology is a subdiscipline of botany concerned with the functioning of plants. Closely related fields include plant morphology, plant ecology, phytochemistry, cell biology, genetics, biophysics and molecular biology.
