Answer:
Ribosomes are macromolecular machines, found within all living cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains. Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists of one or more ribosomal RNA molecules and many ribosomal proteins (RPs or r-proteins). The ribosomes and associated molecules are also known as the translational apparatus.
Explanation:
something that causes an organism to decay. It could have been eaten, or an air pocket formed as it was fossilizing or basically anything that obstructs the formation of a fossil.... you have to figure the rest out; )
<span>Water in the surface zone of the ocean is, for the most part well-mixed.
Zones are also known as layers. Ocean is divided into five layers:
Epipelagic zone (The sunlight zone), Mesoplagic zone (The Twilight zone), Bathypelagic zone (The midnight zone), Abyssopelagic zone (The Abyss) and Hadalpelagic zone (The trenches).

Answer:
a. GC->CG in the protein coding region on a gene. - Base substitution
b. GC->TA in a GAA glutamate codon - Base substitution
c. Loss of three bases GAA for a glutamate codon - Deletion
d. GC->CG in a tRNA gene - Insertion
e. GC->AT in the ribsome binding site of a mRNA - Frameshift mutation
Explanation:
DNA mutation occurs as a result of a change in the gene sequence of the protein being coded by the genes. Several causes of mutation involve radiation, heavy metal exposure, etc. There are different types of gene mutation. These include a deletion where the bases are deleted. Another one is the insertion where a base is inserted into the sequence. This lengthens the base sequence of the gene. Another mutation is the base mutation -this can take place as a result of inversion. Inversion reverses the order of the bases in a sequence like this: normal CGGA → AGGC
These mutations result in disorder e'g Downs syndrome, Puckingtons disease, Cystic fibrosis etc.
Answer:
When precipitation exceeds evapotranspiration and runoff in an area, the result is moist soil and possible flooding. Vegetation reduces runoff in an area but increases evapotranspiration. ... The volume of water moved by a stream in a given time period.
