Answer: The parent organism whose genotype is unknown is heterozygous for purple colour with genotype Ff.

Explanation: The parent organism whose genotype is unknown has a genotype Ff. If (F) represents the allele for purple colour and it is dominant over the allele for white colour (f), a cross between (Ff) and (ff) will produce Ff, Ff, ff and ff. Two of the offsprings are heterozygous for purple colour the other two are white.

Ff x ff = Ff, Ff, ff and ff. Ff will manifest as purple colour because F is dominant over f while ff will manifest as white because f is recessive.

Frameshift mutations ____________.

castortr0y [4]

Answer:

The correct answer is option b. "cause a change in the reading frame of mRNA codons".

Explanation:

Frameshift mutations are among the most drastic mutations because in most cases, result in the translation of a completely different protein. Frameshift mutations are the result of insertions or deletion of one or more nucleotides, resulting in a change in the reading frame of mRNA codons. In consequence, the ribosome translates a different amino acid sequence, based on the new reading frame of mRNA codons.

B) Plant-based diets are usually lower in saturated fat and higher in fiber, which reduces risk of heart disease.

Saturated fats increase the risk for heart disease, so they should be kept lower. Fiber may help reduce overall calorie intake by keeping you full for longer. That way you maintain a healthy weight, which is important for reducing cancer risk.

Explain how the autoinducer molecule in luminescent bacteria signals when to luminesce

strojnjashka [21]

Autoinducer molecules are signalling molecules that need bacteria. In order for the autoinducer molecules to signal, the bacteria must find a way to initiate the signal and a way to respond to the signal it had created. Autoinducer molecules increase in production as the density of the bacteria cell increases.
