The cons of using dispersants are their toxicity to marine environment. Dispersants are also less effective on heavy oils. Dispersants result to oil sinking into the water column from the surface hence this spreads the effect of pollution. Advantages of dispersants are they reduce oil pollution impact onshore and also reduce its risks to marine animals with furs or plumage.
Advantages of using bacteria are that they consume the oil until no residue is left. The bacteria are not toxic like dispersants and reduce in number when the oil pollutant is degraded. Cons of bacteria are that they are unable to break down particular hydrocarbons; they are slow in degrading the oil and are only particularly effective in finishing off oil residue rather than cleaning up large oil spills.

Answer is A. not produce the protein being studied.
Explanation:
The process of generating, creating or replicating a copy of a cell or an organism, which is genetically identical , is called cloning.
There are three types of cloning, these are
1. gene cloning... which is the process of replicating copies of genes.
2. reproductive cloning is the process of generating copies of whole organism.
3. therapeutic cloning... this process is always used when the aim is at creating or generating tissues in replacing diseased or injured tissue by producing embryonic stem cells for experiment.
Answer:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.Body structures can change according to the actions of the organism.have an innate tendency toward complexity and perfection. The actions of organisms as they use or fail to use body structures.
I believe it is the retina that changes shape to focus on distant objects.
