Orographic lifting is associated with?
Agata [3.3K]

Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation

Knowing what we know about the link between genetics, environment and intelligence, what would be your expectations if you were
Vesnalui [34]

Answer:

I would expect them to perform similar.

Explanation:

Studies suggest that intelligence has a genetic component and can, in part, be passed from parent to child - but not only that. There are outer components that contribute to the formation of intelligent individuals. Better nutrition and more access to education would be possible explanations for the progressive increase in intelligence test scores over time.

Homozygous twins are those that are mainly characterized by similarity between individuals. These twins are formed from the same zygote, ie after the fertilization process. Because of this characteristic, they have the same genetic heritage and are therefore considered identical.

As the homozygous twins in their classroom have the same genetic heritage and attend the same environment, we can conclude that their intelligence is influenced by the same factors. For this reason, a teacher who taught these two brothers might have expectations that they would perform similarly in the classroom.
