The correct answer is True
Explanation:
In geography, the term "landform" refers to a natural shape or form that can be found on the surface of Earth such as mountains, hills or canyons. All of these are formed through different processes such as movement in tectonic plates. Additionally, these are considered as a physical feature of Earth as landforms define the shape and features of the Earth's surface and also influenced other physical phenomena such as weather or wind patterns. According to this, it is true landforms is a physical feature on Earth's surface.

Answer:
False
Explanation:
Mass of Particle: Heavier particles will move more slowly and so will have a slower rate of diffusion. Smaller particles on the other hand will diffuse faster because they can move faster.
Answer:
C) production of sperm and eggs
Explanation:
Sperms and eggs are the male and female gametes respectively. Formation of sperms and egg cells require meiotic cell division. Meiosis in sperm mother cells and egg mother cells reduces the chromosome number of half in the sperms and eggs. Meiosis also adds new gene combinations in these gametes by the process of crossing over.
Mitosis cannot reduce the chromosome number to half in the sperms and eggs. Absence of crossing over in mitosis leads to the formation of genetically identical progeny cells from mitosis.
Hence, mitosis can not form sperms and egg cells. If it does, the sperms and egg cells would not have genetic variations and there would be doubling of chromosome number with each round of sexual reproduction.
