Answer:
1. Evolution of chromosome number - fusion, deletion
2. gene trafficking - horizontal gene transfer, exon shuffling, birth of new genes
3. birth of new gene - exon shuffling, fusion and fission.
Explanation:
Evolution of chromosome number occurs due to the fusion and deletion of the chromosomes. Chromosome fusion may result in the speciation and isolation that rise the evolution in chromosome number.
Gene trafficking is the case that is arise due to various reasons such as forming new genes, horizontal gene transfer, and exon shuffling. However the birth of the new gene can be also arise by the fission and fusion and exon shuffling.
thus, the correct answer is - 1. Evolution of chromosome number - fusion, deletion
2. gene trafficking - horizontal gene transfer, exon shuffling, birth of new genes
3. birth of new gene - exon shuffling, fusion and fission.
ANSWER:
chromosomes
Explaination:
Chromosome are made of protein and a single molecule of acid DNA. It's passed on from parental offspring's.
Answer:
D. Areas where the Earth's mantle experiences a high amount of stress.
A. It is likely made up of the metals nickel and iron.
Explanation:
Tectonic plates are located in the uppermost area of the Earth's mantle.
The core of the Earth (innermost layer) is made up primarily of nickel and iron.
I hope this helps! :)
