1. A transgenic organism expresses DNA that has been derived from another species. These organisms have altered genomes and are generated in the laboratory for the purposes of research, for example, the "knock-out" mice are tansgenic mice with a particular gene of interest disabled.
2. Recombinant DNA is the DNA that has been altered to contain genes, or portions of genes, from different organisms. The DNA molecules are formed in the lab using recombination methods to bring together genetic material from multiple sources and therefore creating sequences that are not found in the genome.
3. Restriction enzymes are found naturally in bacteria and they cut DNA at specific nucleotide sequences. These enzymes are also called restriction endonucleases, they cleave DNA into fragments at or near specific recognition sites called restriction sites. They are found in bacteria and archaea and they serve to provide a defense mechanism against invading viruses.
4. Biotechnology is the use or alteration of organisms, cells, or biological molecules to produce food, drugs, or other goods. Living systems and organisms are used to make or develop products. Biotechnology enhances cellular and biomolecular processes to develop technologies and product for the purposes of improving life and health.
5. Polymerase chain reaction is a technique that is used to quickly synthesize billions of copiies of a specific segment of DNA. It is a quick and a very efficient way to generate many copies of DNA. The process is applicable when there are small quantities of DNA to analyze. The events of PCR involves; separation of DNA strands, addition of primers, use of DNA polymerase to produce second strand of DNA.
6. In the process known as transformation, bacteria take up pieces of DNA from the surroundings. Bacterial transformation results from the uptake of naked DNA (DNA without associated cells or proteins). Transformation may also occur naturally in some species of bacteria.
Answer:
The dependent variable is the biological sex of the alligator hatchling.
Explanation:
A hypothesis is essentially a suggested explanation for a specific phenomenon. These hypotheses attempt to offer well-tested reasons for certain observations through experiments.
Experiments are usually carried out under a variety of different conditions to test various hypotheses. To ensure reproducibility, accuracy, and validity of results, several factors must be identified when planning experiments.
For instance, various independent variables are strictly altered and observed while controls are kept constant - this ensures validity and can indicate if the experiment was influenced by external factors. Here, the factor being changed or tested is the temperature, and the factor being observed is the resulting biological sex of the organism.
Answer:
A
Explanation:
the beak is long and curved so the A beak would be perfect (give BRAINLEST please)
Answer is B in my opinion
