It would be A
First is: DNA > mRNA (messenger RNA) > tRNA (transfer RNA) > protein
Answer:
D. Plasmids are nucleic acids which can pass on traits
Explanation:
A Nucleic acid is one of the four biomolecule polymers in living systems. It is made up of monomeric units called Nucleotides. RNA and DNA are the two nucleic acids in existence and they function in storage and expression of genetic information.
According to the question, a colony of bacteria that can break plastics were mixed with the colony that can't break plastics. The two different colonies engage plamids, which conferred the ability to break plastics to some of the colonies that previously couldn't. This tells us that the ability to break plastics in the certain bacteria colony is GENETIC.
If the trait is genetic, the plasmid must be a nucleic acid because of the ability to genetically pass on traits. Note that, a plasmid is an extra-chromosomal DNA (nucleic acid) capable of replicating on its own. Hence, plasmids are nucleic acids which can pass on traits.
Answer:
The right answer for the blank is cleavage.
Explanation:
After fertilization the next step is cleavage in which zygote divide mitotically. As the embryo move from oviduct down the fallopian tube it divide into two cell and then four cells. four cell embryo is known as blastomere.
1.Gravity caused the disk-shaped nebula to shrink.
<span> A cloud of gas and dust started to shrink or more corectly started condensate, due to the force of its own gravity. This process started slow, but increased in velocity as more material were moving toward the center.</span>
2.<span>Rotational motion caused the nebula to flatten out in its disk-like shape.</span> The nebula spined counterclockwise to conserve the angular momentum of the material of the material that were going to the center. This rotation, made the materials that were not in the center flatten out, that's why it looks like a disk.
Phylogenetic tree is the evolutionary tree that shows the inferred evolutionary relationships among various biological species and organisms. <span>Phylogenetic relationship” refers to the relative times in the past that species shared common ancestors.</span>
According to the phylogenetic tree diagram, modern birds are most closely related to an advanced dinosaur.
