<h2>Given :-</h2>
- Cost of school exercise book was Rs. 10
- Now , she had to pay Rs. 12 for it .
<h2>To Find :-</h2>
- The increase percentage of price of that book .
<h2>Solution :-</h2>
<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>
→ Increase of Price = ( Rs. 12 - Rs. 10 )
⇒ Rs. 2
→ Initial Value = Rs. 10
Let's solve by putting the values in the formula !
⇝2×10%
⇝20%
∴ The percent of increase in price of that school exercise book is 20 %
Solution:
We are given:
Number of male fishes surveyed by Elena in a river = 350
Number of male fishes with eggs growing inside them = 150
Therefore the number of male fishes without eggs = 350 - 150 = 200
Now the ratio of male fish with egg cells to male fish without egg cells in the river is:
Therefore, the ratio of male fish with egg cells to male fish without egg cells in the river is 
Answer:
Explanation:
The volume of a rectangular box is given by;
It was given that, the volume of the box is V=8 cubic inches.
The length of the box is l=2 inches.
Let the width of the box be x inches.
The height of the box is 3 inches more than the width. That is
We now substitute all values into the formula to get:
Therefore the required equation is
It’s B) Research database
Answer:
duplication
Explanation:
If we talk about inversion, it inversion, it is a process in which a specific base sequence is inverted or rearranged in such a way that direction is reversed. For example: ABC is changed into BCA, therefore it is not right option.
If we talk about translocation,it is caused by rearrangement of parts between non homologous chromosomes. It can be balanced or unbalanced but it involves two genes or two sets of chromosomes. But in our example, we have only one sequence of DNA under study, therefore, inversion is not possible.
Talking about insertion, it involves addition of one or more nucleotide at certain position of gene sequence. There are chances that it can be an insertion of GGG but the insertion of three G instead of any random nucleotide addition or nucleotide sequence addition is rare. So, there are less chances that this is an insertion and more chances that this is an exact duplication event.
If we talk about duplication, a certain portion of a gene or chromosome is replicated or duplicated in such a way that it results in more than one copies of that region.
Keeping that definition infront, we see that GGG duplicated to GGGGGG. So, if we logically look at the question, duplication seems to be the most appropriate option.
Hope it help!
