The sporophyte of an unknown plant species grows as a separate plant than the gametophyte. The plant produces both female and fl
N76 [4]

Answer:

The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".

Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.

They show alternation of generation in which sporophyte is the dominant stage.

The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.

The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.

The gametes fertilize to produce a diploid zygote.

The zygote divides mitotically and matures into the diploid sporophyte.

Life as we know it depends on the genetic code: a set of codons, each made up of three bases in a DNA sequence and corresponding
Nana76 [90]

The right answer is 5.

To answer this question it is sufficient to take the same approach as the one that concluded that each amino acid is equivalent to 3 codons.

We have 17 amino acids, each of which must have at least one unique code (having two nucleotides A and T) .

it is enough to apply this time to count the number of possible codons to be generated according to the number of nucleotides:

nucleotide set ^ number of nucleotides = number of codons .

2 ^ 1 = 2 (<17)

2 ^ 2 = 4 (<17)

2 ^ 3 = 8 (<17)

2 ^ 4 = 16 (<17)

2 ^ 5 = 32 (> 17)

So, each amino acid has a codon of 5 nucleotides.
