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.

Which organelle is found in both plants and animals:

MrMuchimi

Answer:

The correct answer is E. The organelle that is found in both plants and animals is the Mitochondria.

Explanation:

Mitochondria are cellular organelles responsible for supplying most of the energy necessary for cellular activity (cellular respiration). They act as energy plants of the cell and synthesize ATP at the expense of metabolic fuels (glucose, fatty acids and amino acids). The mitochondria has an outer membrane permeable to ions, metabolites and many polypeptides. This is because it contains proteins that form pores called porins or VDAC (voltage-dependent anionic channel), which allow the passage of molecules up to 10 kDa of mass and an approximate diameter of 2 nm.

Using this codon chart, can someone help me give my the mRNA,tRNA,and amino acids from the original DNA sequence “ACT TTC GAT”

nevsk [136]

Answer:

DNA: ACT TTC GAT

mRNA: UGA AAG CUA

tRNA: ACU UUC GAU

AA: stop-lysine-leucine

Explanation:

mRNA is the complementary sequence of the DNA strand and tRNA is a complementary sequence of mRNA sequence. mRNA is a sequence of bases that is formed by encoding the DNA sequence in the complementary pattern during transcription.

tRNA is complementary of the mRNA code to produce the amino acid which is decided by the codon ( a three- base sequence of mRNA) what amino acid be present in what sequence.

Thus,

DNA: ACT TTC GAT

mRNA: UGA AAG CUA

tRNA: ACU UUC GAU

AA: stop-lysine-leucine (however, after the stop codon amino acid chain terminated in any protein)
