I think it might be the second one sorry if I’m wrong
Answer:
The pitch of a sound is how high or low a sound is when we hear it, whereas the intensity of a sound is the energy/vibrancy of the sound over an area and depends on the frequency of the sound as well.
Some of the factors are:
<span>-Moderate climate.
-central geography,
-ease of transportation,
-highways,
-railroads,
-location near a large body of water
</span>Large cities tend to develop far from cities that had either too hot or too cold temperature. It also must be easily accessible by other regions and provide the people with necessary resources that help them sustain their living (such as water, food crops, woods, etc)
I would say that answer choice C is the best out of this selection. Carbon is the main element in organic compounds, and organic compounds just so happen to make up the cells that carry out life processes for all living things. Hope this helps.
Answer:
Contains large polytene chromosome that permit visual inspection of genomic events.
Were used to study the genetic effects of mutations.
Were used to establish the concept of chromosomal inheritance.
Explanation:
<em>Drosophila melanogaster </em>is a model organism that is used by scientists to study the genes and effect of a mutation on the genes. Drosophila is used as a model organism as it has a very short life cycle and the offspring can be produced in a short duration of time.
Because of these characteristics, Thomas Hunt Morgan wanted to study the factors of inheritance on the <em>Drosophila</em> and concluded in the form of the chromosomal theory of inheritance by the effect of mutation on genes that lead to linkage mapping.
Also, the salivary gland of fruit fly contains the polytene chromosome which allows us to look into the gene events.
Thus, the selected options are correct.
