Answer:
1) start as a carbon molecule in the atmosphere
2) taken in by trees through photosynthesis
3) carbon is taken into decayed organism
4) then it is taken into dead organisms and waste products underground
5) millions of years later, it is stored in a fossil
6) fossil fuels used by factories then emit carbon dioxide back into the atmosphere (back to starting position
if you want the whole cycle then..
7) used again by a tree
8) released as organic carbon (some)
9) tree leaf is eaten by an animal, which then releases carbon either from respiration or when it dies
The question is incomplete as it does not have the options which are:
(a)DNA (b)tRNA (c)rRNA (d)mRNA
Answer:
Option-mRNA
Explanation:
The mRNA is synthesized from the DNA and which is also a type of nucleic acid. When the nucleic acid is extracted from the yeasts and then mixed with the resin beads to which the polynucleotide with thymine base oar is attached.
The mRNA will bind to the resin bead as the mRNA after synthesis undergoes modification and attaches poly A tail to the end of the mRNA at 3' end.
This poly-A tail has adenine which easily binds to the thymine and thus mRNA easily attaches to the resin bead.
Thus, mRNA is correct.
Answer:
a. different shape (e.g. flat or ribbon shaped).
d. larger internal surface area of the lungs.
Explanation:
Amphibians are cold blooded animals. They have a low rate of metabolism . Amphibians are located most where there is water or in moist environment because of their skin and how important it is to keep their skin moist.
Amphibians breathe through their skin and this can be called cutaneous respiration. Their lungs are not well developed therefore they undergo a very slow diffusion of oxygen through their blood.
For Amphibians that are larger than bull frogs, they obtain a very sufficient rate of diffusion of gases due to the following reasons:
a. Internal surface area of the lungs: Amphibians that are larger than bull frogs tend to have a more developed respiratory organs which means there lungs have a larger surface area and they are well developed.
b. They have a different body shape: Amphibians larger than bull frogs could have a flat or ribbon shape and their body shapes make it easier for respiratory gases like oxygen to permeate or enter their skin easily.
Answer:
The total amount of matter on Earth constantly increases.
Explanation:
This is because there are always new things taking birth every second and they have matter in them, so the matter is increasing constantly.
