Each combination of 3 nucleotides are called a codon. The codons then determine which amino acids are going to be inserted in the protein
Answer:
Non polar molecule, small
Explanation:
Cell membrane is a selectively permeable membrane.
Factors that affect permeability of a molecule are-
A. Size - Small molecules can easily pass through the membrane than the large molecules.
B. Solubility - Non polar molecules ( eg. carbon dioxide) are lipid soluble in cell membrane , so they can easily pass through the membrane than the polar molecules (eg. glucose)
A very thin ring in a tree would indicate that there was little or no water in the area
Carbon dioxide is emitted into the air from cars burning gas as well as many other toxins we breath everyday.
Answer: alpha
Explanation: Alpha particles are fast moving streams of positively charged particles that are shown to be Helium nuclei. They have a mass
number of 4 and an atomic number of 2 and a charge of +2. Alpha particles are represented as 4He2. When 238U92 becomes 234Th90, it emitted a helium nucleus 4He2. The equation for the decay is 238U92 ---> 234Th90 + 4He2.
