In chromatin, substitution mutations are most common in linker regions. Option d is the correct answer.
Mutation by substitution When one nucleotide base is replaced by another, this occurs. Mismatch mutation A type of substitution mutation in which a single nucleotide is replaced, resulting in the coding of an incorrect amino acid, which usually results in a malfunctioning protein. Silent mutations are the result of genetic code redundancy (degeneracy): This is false, as silent mutations are the result of a base substitution that has no discernible effect on a protein's amino acid sequence.

I think 5 is carbon dioxide
The correct answer should be constructive forces.
<span>According
to the theory of plate tectonics, volcanism, mountain building, and
other constructive forces receive energy from Earth’s interior, where constructive means that they influence the lithosphere.</span>
<u>Answer</u>: Infundibulum, ampulla, isthmus, uterus.
<u>Explanation</u>:
- The ovary produces the egg and, it releases one unfertilized egg every month.
- The egg then travels through the fallopian tube to the uterus.
- The fallopian tube consists of three parts:
1. <em>Infundibulum</em>- it is the most distal portion of the fallopian tube which receives the egg coming out of the ovary.
2. <em>Ampulla</em>- This is the next portion of the fallopian tube which is ciliated and is the site of fertilisation of the egg.
3. <em>Isthmus</em>- it is also a ciliated region which controls the transport of both sperm and the embryo.
- Finally, after passing through the isthmus the fertilized egg reaches the uterus where implantation takes place.
- <em>So the journey of the egg from the ovary to uterus follows the pathway, ovary---> infundibulum--->ampulla--->isthmus--->uterus.</em>

The correct answer is D. None of the above
Explanation:
Urban sprawl or the expansion of human settlements such as cities has multiple negative consequences on the ecosystems. This includes deforestation because trees are usually cut to build houses and other human structures. Indeed, most threes and plants are removed for human construction. This also implies a loss of natural resources that include a wide variety of plants, animals, and even water as nearby bodies of water might be polluted. Besides, this general pollution increases in the area this includes noise pollution, water pollution and air pollution that result from human activities. Thus, all are possible consequences of urban sprawl; therefore, the correct answer is none of the above.
