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.
The organelle that a eukaryotic cell would have a large by number of if the cell used a lot of energy would be the mitochondria. These are also commonly known as the powerhouses of the cell, as they are responsible for undergoing a vital cellular pathway needed for the other organelles to have the energy to function: cellular respiration.
For example I would do the stem.
The stem consists of xylem and phloem. The xylem is for transporting water and mineral ions which is absorbed by the root to the leaves. Meanwhile, the phloem is for transporting sucrose and amino acids from the leaves, to the storage place such as roots or stem.

Answer:
Trout is a very common freshwater fish. The lifespan is very small.
Explanation:
The trout population is affected by the climate change and also the pollution present in the freshwater. These fish variety travel for across to lay eggs. And after laying eggs they just die. The climate change and the the fishing of this variety has negatively affected the population. There are lot of varieties of trout fish like rainbow albino etc.
The rise in temperature and flood in a river is a major factor which effects the population of this fish. in USA when the temperature rises it result in flood condition in the river which affects the lifestyle of this fish.
