<em>A megaphone used by a cheerleader can allow people on the opposite side of a field to hear her better because;</em>
D. Solid objects can change the direction of sound waves; megaphones allow users to determine the general direction of the sound.
<u>Determination of the general direction of the sound lessens its dispersion and thus, it reaches the observers at a higher intensity, hence it being louder.</u>
Answer:
The correct answer would be A). They will all be blue.
Genotype of the parents are BB and bb.
As both are homozygous in nature so, each will produce only one type of gamete.
BB will produce gamete B and bb will produce b as its gamete.
The cross will results in the production of offspring each with genotype Bb.
We know that blue is a dominant trait and thus it will be expressed in heterozygous condition (Bb).
Hence, all offspring would be blue in color.
Answer:
I can't read the name of the graphs, but it is the one that is the graph that is in the bottom left corner (grassland is what I think it says.)
Explanation:
We are talking about equilibrium, so the graph is going to depict equality. As you can see, this graph is the most consistant when compared to the other graphs.
Ecosystem
Explanation:
The relationship between the living and non-living things forms an ecosystem.
The non- living things like water, air, soil and other are required by the living organisms for leading their life cycle.
The living things forms the integral part of the natural cycling process of water, air and soil.
Thus this can be said that both living and non-living things are interdependent on each other and forms an ecosystem.
For example, if plants do not get water they will not be able to produce food also the transpiration will not occur which is an important part of the water cycle.
It would be most likely that their children has blood type AB.
