- pressure
- atmosphere
- temperature
- viscosity.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Movement by pseudopodia is possible only over a surface. It depends upon active contraction of the ectoplasm (plasmagel) at the posterior end of the body. This leads the endoplasm (plasmasol) to flow forward into the expanding pseudopodium. This process involves continuous solation at the posterior end and gelation at the anterior end. This is called sol gel or change of viscosity theory, advanced by Mast and Pantin.

Biological Classification
The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
