Nearly all life on Earth ultimately gets its energy from the sun, which gets "its"energy through nuclear fusion. <span>With the exception of hydrogen, all of the chemical elements needed for life were produced by nuclear fusion of lighter elements, either in the cores of stars or in the shock waves of supernova explosions.</span>

Wind dispersion of reproductive cells allowed in seedplants to colonize
land away from water supplies. If water is needed to
passively transport gametes to each other and protect them from desiccation
plants were limited to densely inhabited space near water sources.
Bryophytes & ferns (seedless) are dependent on moist environments
for reproduction but the first seed plants developed an alternate
delivery system allowing independence from water- assisted reproduction.
Conifers produce pollen that can survive by carrying water and
nutrients along. Wind can now carry these male gametophytes to female
gametophytes under the scales of a cone. Fertilization produced a
diploid seed. The seed is protected and can survive dry conditions for a
period of time before growing. Pollen and seeds transferred a conifer’s
water dependence for their reproduction to wind dependence. </span>
Answer:
C. CGA-UUA-CUA
Explanation:
The deoxyribonucleic acid (DNA) is a double helix molecule which is composed of four letters or 'nucleotides': guanine (G), cytosine (C), adenine (A) and thymine (T). The base-pair rules state that in the DNA double helix, G always pairs with C, while A always pairs with T. Moreover, during transcription, a base named uracil (U) replaces T in the resulting RNA sequence. Therefore, in this case, the complementary sequence (i.e., antisense strand) to the mRNA sequence is CGA-UUA-CUA.
Answer:
That wall is much larger.

wall is diff from cell.
