Plasticity is most adaptive when the environment change <u>Slowly and predictably </u>throughout an organism's life.
The ability of individual genotypes to create various phenotypes when exposed to various environmental situations is known as phenotypic plasticity. Here, the emphasis is on the role of plasticity in evolution rather than the evolution of plasticity itself, i.e., the evolution of phenotypic traits and organismal variety through plasticity. Phenotypic plasticity is a crucial characteristic of developmental systems that enables the organism to deal with environmental variability and/or unpredictability, although its significance for adaptive evolution is still debated.

All large radioactive atoms decay into smaller atoms by emitting alpha particles which consists of two protons and two neutrons. An alpha particle can also be thought of as the nucleus of a helium atom and as such they are sometimes referred to as He2+ . The positive charge is due to the lack of two electrons.
Same number of atoms on the outer shell, will have similar melting and boiling properties
Question:
Which of the following aids in the weathering and transportation of rocks?
A.
wind
B.
clouds
C.
sunlight
D.
all of these
Answer:
Winds aids in the weathering and transportation of rocks
Explanation:
Weathering is process of break down of the rocks, and then it gets dissolved into small pieces by the means of physical, physiological, chemical or also biological process. Transport of these particles helps in the completion of the process, this leads to the movement of the materials from one place to another. Basically the erosion takes place by, water wind and ice. Hence two types of weathering have been reported like mechanical and chemical.
