Where would snow or rain be expected to fall on a mountain?
nignag [31]

Answer:They receive more rainfall than low lying areas because the temperature on top of mountains is lower than the temperature at sea level.

Winds carry moist air over the land. When air reaches the mountain, it rises because the mountains are in the way. As the air rises, it cools, and because cool air can carry less moisture than warm air, there is usually precipitation (rain).

What is the primary difference between a hypothesis and a theory?
VLD [36.1K]

Answer:

A theory is an explanation that why something occurs while the hypothesis is a prediction or guess about what will happen.

A theory is a conclusion that is given after many experiments while a hypothesis is an idea that is given before an experiment that what will happen as a result experiment.

The periodic theory explains that elements would repeat their properties repeatedly. The theory also made a hypothesis that certain elements would be discovered.

Which of the following statements is TRUE?
erica [24]

"The origin of a muscle is attached to the bone that does NOT move" is true among the following statements.

The origin and insertion of an attachment are the points of attachment. When a muscle contracts, the point of attachment known as the origin remains stationary. As a result, when contraction occurs, the origin bone is the more immobile of the two bones at the joint.

Skeletal muscles have two or more points of attachment to bone, or occasionally to other muscles or tissues. The attachment is said to as having an origin if the location is a bone that is stationary during an action. The attachment is referred to be an insertion if the location is on the bone that moves during the motion.

The triceps brachii has four places of attachment: three origins and one insertion on the ulna (two on the humerus and one on the scapula).

What if a mutation that makes the wing color in butterflies lighter appears inthe population? How would that change your strateg
lana66690 [7]
When you see butterflies with different wing colors, you should conclude that there's a difference in their protein expression, so there's a mutation somewhere in the genome of the butterfly with the new color.

To answer the first question, if the desired color exists in nature, you should take the specific butterfly's caterpillars and raise them. If the desired <span>butterfly color doesn't exist in nature than you should wait for the mutation to occur (which could take many years) or look for the gene in the butterfly which is responsible for the pigmentation of their wings.
</span>
For the second question, mutations in the gene of the coloration of the butterfly's wing could change the color, so what scientist do is to try to provoke different mutations on the caterpillar's gene until they have a butterfly with the desired color.
So everything is about molecular genetics, every difference between species is due to mutations.
