ANSWER
mRNA - formed from the DNA gene sequence with the help of RNA polymerase.
EXPLANATION
mRNA contain codons which are complement to
tRNA anticodons.
rRNA formed in nucleolus.
tRNA carries the amino acid.
Answer: D
Explanation: Cellular respiration involves the combustion of of food (stored in the form of sugar) which is glucose to produce energy in the form of Adenosine Triphosphate (ATP) - which is the energy current, along with the production of carbon dioxide all in the presence of oxygen - besides, it is combustion, so it involves the use of oxygen.
In essence, generally, it is simply the burning/combustion of glucose to produce energy in form of ATP.
Answer:
C. Vascular tissue, B. Seeds and then D. flowers
Explanation:
The land plants were evolved from the aquatic plants especially algae named Chara.
The land plants adapted to survive on the terrestrial habitat by forming structures first of which is the vascular tissues.
The vascular issues developed in the trees in the group of organisms called the pteridophytes. Later plants started protecting their embryos in a hard coat layer which could protect the embryos during adverse conditions. These structures were later called the seeds which were a characteristic feature of the gymnosperms. Later plants developed the flowers which acted as modified reproductive structures and the plants were called angiosperms.
Thus, C. Vascular tissue, B. Seeds and then D. flowers is correct.
Answer:
Explanation:
The choices provided are:
a.restaurants that use C-8-coated cookware
b.cookware manufacturers who make pans out of steel only
c.stores that sell C-8 nonstick cookware
d.individuals who use steel cookware at home
From these choices B is the correct answer.
Restaurants that use C-8 cookware will not profit from using it but will need to lose money by replacing the old C-8 coated cookware.
Stores that sell this nonstick cookware will also need to replace their inventory so they won't be making extra money, only losing it.
And individuals at home will still be using steel cookware and won't benefit or lose anything by this change with the regulations of the c-8 coated nonstick cookware.
