c. Birth rates are high
Explanation:
A wide base in the population pyramid shows that there is a large population of young people with high fertility rate or birth rate and high death rate.
From the graph, it can also be concluded that narrow tip at the top shows that lesser older people are in the population.
This pyramid shown in the diagram is a triangular age pyramid. In this type of pyramid the pre-reproductive individuals are high reproductive individual are moderate and non-reproducing individual is less. In such pyramid we find population grows.
Suppose in a family of ten 6 are pre-reproductive, 2 moderate reproductive and 2 post-reproductive. We will see the in the course of moderate and post-reproductive will die and those six of pre-reproducing age will increase the population.

The sigmoid colon, which begins in front of the pelvic brim, is a section of the large intestine that is located in the pelvic cavity.
The sigmoid colon typically measures 25 to 40 cm in length (10 to 15.75 in). As a continuation of the descending colon, the sigmoid colon is a "S"-shaped section of the large intestine that starts in front of the pelvic brim and changes into the rectum at the level of the third sacral vertebrae.
<h3>The large intestine is it located in the pelvic cavity?</h3>
The urine bladder, the remainder of the large intestine (the bottom region), and the internal reproductive organs are all located in the pelvic cavity, which is the lower part.
<h3>Which digestive system organ is located in the pelvis?</h3>
The inferior portions of various abdominal viscera are located in the larger pelvis (terminal ileum, cecum, sigmoid colon).
<h3>Where in the abdominal cavity is the big intestine?</h3>
From the ileocecal junction to the anus, the large intestine continues the ileum for 1 to 1.5 meters. The majority of the large intestine is found in the abdominal cavity, and the remaining part is found in the pelvic cavity.

Answer:
2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG
Explanation:
Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!
In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G
In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.
In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.
In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.
Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.
