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:
Geosphere and Hydrosphere
Explanation:
Rain is water, and the volcanic eruption from the valcano is rock
The percent by mass of an answer made from 14 g NaCl (the solute) and 61 g water is 18.66%
14 g + 61 g =75.0 g - mass of the solution
mass % = (mass solute/ mass solution)*100% = (14/75.0)*100% =
= 0.186*100% =18.66%.
What is the percent by mass?
Mass percent is another method of expressing the composition of the solution mixture. It describes the amount of solute (grams) present in 100 gm of the solution.
