Answer:
Trees soak up rain from the ground and store/use it. Without trees to soak up the water on the ground, it stays put > pools > floods.
Also, a little bit of rain stays on the trees' leaves. This may not seem like a lot, but there are many trees in a forest with many many leaves all holding water :)
Explanation:
B) 25%
C) 40%
D) 50%
Answer: The correct answer is 25%.
Black color (B) of horse is a dominant trait over brown (b) color, which is a recessive trait. As we know that dominant gene masks the expression of recessive gene, therefore brown horse color will only be produced in the genpotype bb.
On the other hand, there are two possible genotypes for black horse color that is BB and Bb.
As per the question, parental genotypes are Bb and Bb. When they are crossed, they will produce 25 % foal with brown color (bb).

Answer: Portions called introns are removed and the remaining exons are spliced together
Explanation:
The messenger RNA obtained after transcription is known as primary transcribed RNA or precursor RNA, and it has to undergo modifications before exerting its function. This is called RNA processing or maturation.
In the DNA sequence, the coding content of a gene is not continuously distributed along the gene, but has discontinuities, called introns, whose sequence does not encode proteins.The parts of the sequence that encode proteins are called exons. Through a process called splicing (which is one of the modification that are part of the RNA maduration), the introns are eliminated and the exons are joined forming a mature messenger RNA molecule that will be used for protein synthesis.
So the exons are part of the region of a gene that is not separated during the cutting and splicing process and is therefore kept in the mature messenger RNA. Each exon codes a specific portion of the entire protein, so that the set of exons forms the coding region of the gene.
(B) Force of gravity decreases
(C) The volume of water increases
(D) The slope of the river increases
