The correct answer is: physical activity.
Basal energy expenditure is defined as the amount of oxygen (O2) which is consumed while resting and fasting, extrapolated to 24 hrs. Basal energy expenditure is used to determine an individual's caloric needs and it depends on gender, age, activity..
Answer:E. Founder effect
Explanation:
The founder effect is a phenomena that can be used to describe the fact that a new species develop from the parent species, when a small group of the parent population get separated. With due course of time such separated population becomes genetically different from the parent population.
The correct answer is option (D) eccrine sweat glands.
Eccrine sweat glands are the major sweat glands found abundantly on the skin especially in palms, soles, head. They are involved in the secretion of a clear, sterile, odourless substance called the sweat. They are involved in the process of thermoregulation which is the ability of an organism to maintain a particular temperature irrespective of any temperature or changes in the environment.
During a hot day or intense exercise, the body temperature is maintained by the stimulation of the eccrine sweat glands by the nervous system to secrete water onto the surface of the body which gives a cooling effect by evaporation. Thus, the production of the eccrine sweat acts as a mechanism for temperature control.
Answer:
The two structures used in membrane transport are 1 integral membrane protein 2 peripheral membrane protein.
Explanation:
The various protein present in the plasma membrane help the later to exhibit its function to transport various solute molecules and ions across the membrane.
Integral membrane protein such as Na+K+ATPase helps in the transport of Na+ ions inside the cell and K+ ions outside the cell against their concentration gradient.
Peripheral membrane proteins are present in water soluble region of either extracellular region or cytoplasmic region or both.Peripheral protein also helps in the transportation of various solute molecules .
