Changes in DNA are known as mutations and can be sometimes produce beneficial changes in population. A mutant form of the normally light-colored peppered moth is dark-colored. The dark-colored moth blends in with soot-covered trees in heavily polluted areas.Why would the dark-colored mutation be beneficial in a polluted area?
Answers
The dark-colored mutation could be beneficial in a polluted area because this phenotype may confer an adaptive advantage.
A mutation is any alteration in the nucleotide DNA sequence (genome) of an organism.
Mutation can be beneficial, deleterious, or neutral depending on the environmental conditions in which the individual lives.
In this case, the dark-colored mutation could be beneficial for an insect living in a polluted area because bright-colored phenotypes make the moth very conspicuous to visual predators.
In consequence, dark-colored insects have more chances to survive and reproduce (i.e., they have an adaptive advantage), thereby these insects have more chances of passing this mutation to the next generation.
In conclusion, the dark-colored mutation could be beneficial in a polluted area because this phenotype may confer an adaptive advantage.

a. angle of reflection
b. angle of incidence
c. normal
d. law of reflection
Answers
Answer:
c) Normal
Explanation:
Reflection is a phenomenon typical of light wave; it occurs when a ray of light hits the interface between two mediums, and bounces off back into the original medium, at a certain angle.
The direction of the reflected ray is determined by the law of reflection, which states that:
1) The incident ray and the reflected ray, together with the normal to the interface (the perpendicular to the interface), all lie within the same plane
2) The angle of incidence is equal to the angle of reflection:
where
is measured as the angle between the incident ray and the normal to the interface
is measured as the angle between the reflected ray and the normal to the interface

A habitat change can be caused by introduction of an invasive species, wildlife and mudslides. Therefore, option (d) is correct.
What is habitat change?
Habitat change can take place naturally through disease, droughts, fire, hurricanes, mudslides, volcanoes, earthquakes, or precipitation, etc.
However, it is commonly induced by human activities like land use change and physical modification of rivers.
Habitats can change over time due to natural and manmade effects. Natural influences involve seasonal changes, drought, flooding, and natural succession. Manmade effects include conversion of land from forests to farms, and pollution.
Habitat destruction through natural processes like volcanism, wildfire, and climate change. Habitat fragmentation of tropical rainforests led to a great loss of amphibian diversity, but at same time the drier climate spurred on a burst of diversity among reptiles.
An invasive species are an introduced organism that gets overpopulated and harms new environment.
Therefore, mudslides, wildlife and invasive species can cause habitat change.
