Answer:
Failure of chromosome to separate
Explanation:
The main essence of meiotic division is to form daughter cells with a reduced number of chromosomes that will maintain the correct chromosomal number in an organism. This is achieved when chromosomes separate during gamete formation (meiosis) to produce haploid (n) gametes.
However, a case may arise whereby chromosomes fail to separate during the anaphase stage of meiosis. This case is referred to as MEIOTIC NON-DISJUNCTION. As meiosis occurs in two stages i.e. meiosis I and II, so does meiotic nondisjunction. It can occur in meiosis I, where homologous chromosomes fail to separate or meiosis II, where sister chromatids fail to separate.
If it occurs in meiosis I, Two gametes will have a n-1 chromosome number i.e. one chromosome is missing while Two other gametes will have n+1 chromosome number i.e. one extra chromosome is added.
If it occurs in meiosis II, two normal haploid gametes (n) will be produced while the other two will have a n+1 and n-1 chromosome number respectively.
When these abnormal gametes (n+1, n-1) fuses with a normal gamete (n), the resulting organisms possess a chromosomal anomaly called ANEUPLOIDY i.e. a disorder in chromosomal number. The organisms will have 47 and 45 chromosomes depending on whether n+1 or n-1 gametes is involved respectively.
Answer:
Golden Eagles have a square tail, fully feathered legs and large talons. Females are much larger than males and they both have the same coloured plumage. Golden Eagles are very agile in flight and they can remain in the air for hours. They have a graceful, soaring flight with their wingtips being slightly upturned.

The best answer in this case is C, "the researchers applied creativity to solve a problem in running an experiment".
Distributing the computing load across the global community by sharing processing power is a creative response to tackle the challenge in simulating protein folding for the experiment. This does not change or reduce the scientific merits of the experiment, so we can discount the first two answers (a & b). Answer d talks about well established scientific techniques, although the question wasn't really centered around the specific techniques, so it's not as relevant an answer as C.

Proteins - enzymes, hair
Answer:
The concentration of solution that contains a large amount of solute in the solvent could be described as concentrated
Explanation:
The concentration of solution that contains a large amount of solute in the solvent could not be described as diluted because i have just a little amount of solute.
The concentration of solution that contains a large amount of solute in the solvent could not be described as polar because polarity has a relation between molecules and its charges. Solvents or solutes are polar or not.
The concentration of solution that contains a large amount of solute in the solvent could not be described as unsaturated because unsaturated means that the mass of solvent is greater than solute.
