Answer:
Written below.
Explanation:
5. During meiosis, a reproductive cell and its nucleus divide twice and produce four cells––two pairs of identical haploid cells.
6. Homologous chromosomes are two pieces of DNA within a diploid organism that carry the same genes, one from each parental source. In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes.
Answer:
No, it has too many variables or possible changes.
Explanation:
If you carried out an experiment or research on something, you have to given the same environmental and soil conditions to the factors. In this experiment, Kevin put the first plant in large pot and the other two plants in the field conditions. For performing correct experiments, Kevin put all the plants in separate pots or in the field conditions.
An intron is a non-coding region of DNA. During alternative splicing, introns are removed.
- During eukaryotic transcription, a fragment of DNA (e.g., a gene) is used as a template to synthesize a complementary RNA sequence, usually a precursor mRNA (pre-mRNA).
- Subsequently, this pre-mRNA is processed by a mechanism called alternative splicing in order to produce a mature mRNA which is then used as template to synthesize a protein by a process called translation.
- During alternative splicing, non-coding regions of a gene called 'introns' are removed, where coding regions called 'exons' are spliced back together.
- If a cell transcribed and translated a gene’s intron by mistake, then additional amino acids would be inserted into the protein and therefore the resulting protein will be longer than normal.

Answer:
The Grants have focused their research on the medium ground finch, Geospiza fortis, on the small island of Daphne Major. Daphne Major serves as an ideal site for research because the finches have few predators or competitors. (The only other finch on the island is the cactus finch.) The major factor influencing survival of the medium ground finch is the weather, and thus the availability of food. The medium ground finch has a stubby beak and eats mostly seeds. Medium ground finches are variable in size and shape, which makes them a good subject for a study of evolution.
