Answer:
Ribosomal RNA (rRNA)
Explanation:
associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.
Answer:
D. They define geological periods because scientists use them as reference points for tracking the history of the earth.
Explanation:
Catastrophic events related to changes in geological timeline are very useful in defining geological periods.
These events have very significant appearance in the geological record and can be used to determine the history of the earth.
The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.
Geologists use these events that are often wide spread to delineate geological periods.
Answer:
Adaptations. Organisms have specific structures, functions, and behaviors that enable them to survive the biotic and abiotic conditions of the particular ecosystem in which they live. Organisms possess adaptations to both biotic and abiotic factors in their ecosystem that increase their chance of survival.
Explanation:
Answer: The equation you are going to use is D=M/V. Plug the density number in that the question provided and do the same for volume and solve for m.
Explanation:
11.3=m/6.7
11.3x6.7=m
Answer:
1. B. Methane
2. C. Methane collection system
