The process of removing waste products from the blood using a machine is called: MCQ with Answer and Explanation

Explanation:
The respiratory system, primarily the lungs, facilitates the exchange of gases (oxygen and carbon dioxide) between the blood and the external environment. The circulatory system, centered around the heart and blood vessels, transports blood containing oxygen, nutrients, hormones, and waste products throughout the body. The excretory system, primarily the kidneys, filters blood to remove metabolic waste products and excess water, excreting them as urine. All statements are correct.

Explanation:
A virus is an obligate intracellular parasite. The basic structure of a virus particle, or virion, consists of genetic material (either DNA or RNA, but never both) enclosed in a protective protein coat called a capsid, made of subunits called capsomeres. Some viruses also have an outer lipid envelope derived from the host cell membrane.

Explanation:
Stomatal transpiration accounts for about 80-90% of total water loss from plants. Stomata are microscopic pores on leaves, surrounded by guard cells. Cuticular transpiration occurs through the cuticle but is minimal. Lenticular transpiration is through lenticels on woody stems. Hydathodes are involved in guttation, not transpiration. Transpiration creates transpiration pull essential for water ascent in xylem.
