Spindle Fibres are those structures which move chromosomes only during cell division.
And these spindle fibres are formed by the command of centrioles which during the process move to the on the opposite poles and helps the cell to prepare for division.
Food is the source of energy that is used by the organism for the process of metabolism. Maggots are the larva of flies and depend on dead and decaying matters.
Maggots are:
Option C. Decomposers
This type of organism can be explained as:
- The organism is classified into different classes according to the nature of its feeding habits.
- <u>Autotrophs </u>are called the primary producer and break inorganic compounds into organic for energy.
- <u>Producers </u>are the organism that produces their food by converting solar energy into chemical energy.
- <u>Decomposers </u>are small-sized organism that lives in soil and breaks the organic compound of dead and decayed bodies.
- <u>Heterotrophs </u>are organism that depends on other sources and producers for energy.
Therefore, maggots are decomposers.

Answer:
If an mRNA strand is 6399 nucleotides long, it will code for 2132 amino acids, as the last triplet is the terminating codon.
Explanation:
Codons are found in the RNA chain and are made up of nucleotides trios, whose specific sequence determines the genetic code.
There are 4 nitrogenous bases in RNA - Adenine, Guanine, Cytosine and Uracil - which when combined in trios give rise to 64 possible codon combinations that code for 20 amino acids, so an amino acid can be formed by more than one codon.
Determining how many amino acids are encoded according to the amount of nucleotides in the mRNA would be as easy as <u>dividing the number of nucleotids in the chain by 3</u>, but considering that the last codon is not taken into account, since it is the termination codon.
- Amino acids = (amount of nitrogenous bases in mRNA / 3) - 1
- Amino acids = (6399 / 3) - 1
- Amino acids = 2133 - 1 = 2132
