<h2>Answer</h2>
Trees that grow in a forest tend to grow very tall, with few branches. The same species of tree grown in an open area tends to grow shorter and wider, with many branches. The stimulus responsible for these different growth patterns is the amount of —

Stamens, sepals, petals, carpels, and pinecone scales are all modified leaves.

What are modified leaves?</h3>
The structure and function of a leaf can be modified over the course of evolution as a plant adapts to a particular environment.
Some leaves may be converted to storage structures below ground (as with a bulb) or into plant defense structures (as with a spine).
When function of the leaf blade is no longer primarily photosynthesis, some other plant part is usually modified to take its place.
A phyllode is a petiole that has become flat and photosynthetic, looking much like a leaf blade.

Answer:
It would prevent the ends of the plasmids from being ligated.
Explanation:
The function of this enzyme is that it catalyzes dephosphorylation, removing phosphate groups from the 5' ends of the the DNA strands. It particularly functions in preventing the re-ligation of a plasmid DNA that has been linearized by this method such that other DNA fragments can be ligated into the vector. It is particularly used in cloning.
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.
