Answer:
Cloning is the mechanism by which one living organism takes genetic material and produces identical copies of it. Cells, organs, chromosomes and whole species have been cloned by geneticists.
<u>The scientist need to take of some of the issues before cloning of sheep are as following:</u>
- Conflict with long-standing religious and social values about human dignity, probably infringing the principles of equality, identity and autonomy of each person.
- Cloned embryos face the same difficulties as naturally occurring pregnancies, plus others that are unique to cloning, so embryonic condition should be maintained.
- Cloned embryos surviving pregnancy may be born with a number of birth defects and other health issues.
- However, cloned cells can lack the programming required to tell the genes when to turn on and off. The outcome could be disorganised cell growth or abnormal functioning of the cell, all of which may lead to death of an organism.
Sample could get contaminated with an acid. because vinegar contains acetic acid.Acetic acid is the second simplest carboxylic acid (after formic acid) and consists of two small functional groups, an acetyl group (sometimes symbolized as Ac) and a hydroxyl group (AcOH); it can also be viewed as a methyl group and a carboxyl group linked. It is an important chemical reagent and industrial chemical

All of the traits combined that actually show up in the individual - this is the phenotype (the physical, observed expression of genes
Each person has two genes. The DOMINANT TRAIT will show up if that trait is present on one of the two genes.
The RECESSIVE TRAIT can be hidden by the dominant trait. It will only show up if a person has both genes for that trait.
An observable form of an inherited characteristic - A trait
The traits that an individual has inherited, including the ones that do not show up - this is the genotype, as it accounts for the set of genes in our DNA
Answer:
f. cyanobacteria
Explanation:
Cyanobacteria are a group of photosynthetic bacteria. They have the ability to use water as a source of an electron during the process of photosynthesis. Splitting of water produces molecular oxygen that is released into the surroundings. In this way, cyanobacteria release oxygen gas in the air. The primitive atmosphere of the earth was reducing and did not have oxygen gas. The first photosynthetic organisms that could split water during photosynthesis are supposed to be cyanobacteria. These prokaryotes added oxygen to the atmosphere of the early earth and gradually made it oxidative from reducing.
