7. What was his hypothesis?
8. How did the results of his experiment compare to his original hypothesis?
Answers
It affected the color of dark colored moths because they were able to camouflage into their environment better because of the soot from the factories, therefore increasing the number of dark moths that survived in their environment over light colored moths.
Natural selection is when the environment and environmental factors affect an organisms ability to survive and reproduce in that environment, causing only the most fit organisms to be able to survive and reproduce.

A. snow only occurs in the winter while freezing rain can
occur in the summer
B. freezing rain usually occurs when no clouds are
present while snow only occurs when there are clouds
C. snow freezes in a cloud then falls to Earth while
freezing rain freezes after it hits a cold surface
D. there is no difference between snow and freezing rain
Answers
Answer:
answer a,b,c is the difference between snow and freezing rain
As water vapor in the sky condenses around minute dust or salt particles, snow is created as a type of precipitation. Ice crystals are created when the water vapor freezes around these particles. The correct option is C "Snow freezes in a cloud and then falls to Earth while freezing rain freezes after it hits a cold surface" is correct.
Snowflakes are created when these ice crystals group together. When snowflakes are too heavy to remain floating in the air, snow falls to Earth.
Raindrops that fall through a layer of cold air condense into freezing rain, which is a kind of precipitation. Raindrops freeze as they come into touch with cold surfaces, such as the earth. Since it may make sidewalks and roadways slick and ice, freezing rain can be extremely dangerous.

1. Fill in the table noting which species of xenite has each characteristic, marking each
yes or no. (3 points)

Observing each of the animals shown we have to classify what each one of them has that differs from the other in this way, the evolutionary process of each one is:
Xenite A: Have eyestalksXenite B: Have eyestalks and mouthXenite C: Have eyestalks, tail and mouthXenite D: Have spine and eyestalksXenite E: Have spine, eyestalks and mouth.What is evolutionary process?Evolutionary processes aim, therefore, to generate greater adaptation of species in an environment. This concept of adaptation is related to several other evolutionary processes, mainly speciation, when new species of organisms are formed from gradual changes in preexisting species.

The genotype of the short-haired parents that produced some long hair offsprings is probably heterozygous.
What is heterozygosity?Heterozygous means an organism which has two different alleles of a given gene.
An organism that is heterozygous posseses two different alleles of the same gene. For example, in this gene coding for hair length;
L represents short hair (dominant)l represents long hair (recessive)Therefore, if two short-haired parents produce 100 offsprings and 25 of them are long-haired, it means that they were probably heterozygous for the short hair.
