Answer:
See explanation
Explanation:
A gene mutation can be defined as a permanent change in the DNA sequence that composes a gene, resulting in the observation that the sequence differs from what is obtainable in most individuals that make up the population. Mutations range from a change in a single DNA building block (change in the sequence of base pairs) to changes in a large segment of a chromosome that includes multiple genes.
Mutation in the color of the wings of the housefly can be passed on to the next generation. If this trait enhances survival of the butterflies, the orange winged butterflies will eventual become extinct and become entirely replaced by the white winged butterflies. This implies that gene pool has been completely modified.
Answer:
d. Radio wave
Explanation:
There are three types of mechanical waves, transverse waves, longitudinal waves, and surface waves
Option (a) is correct.
A reducing agent is the one which loses electrons to other substance and an oxidizing agent is one which accepts electrons.
Here, In

, Cr has oxidation number 6+ in the L.H.S of the equation, but on R.H.S its oxidation number is 0 i.e. it Cr has gained electrons such that total charge is 0.
And the oxidation state of Al in the left-hand side of equation is 0 and in right-hand side, it is +6.i.e. it has donated its electrons to Cr.
Hence, Cr is the oxidizing agent and Al is the reducing agent.
