Answer:
B. Ice gains heat becomes liquid, gains more heat, and forms a gas.
Explanation:
I got you :)
The molecular clock (based on the molecular clock hypothesis (MCH)) is a technique in molecular evolution that uses fossil constraints and rates of molecular change to deduce the time in geologic history when two species or other taxa diverged. It is used to estimate the time of occurrence of events called speciation or radiation. The molecular data used for such calculations is usually nucleotide sequences for DNA or amino acid sequences for proteins. It is sometimes called a gene clock or evolutionary clock.
Answer:
Gene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule. The cell reads the sequence of the gene in groups of three bases.
Explanation:
The tails point inwards. Since the outside layer of the bilayer is in a watery environment, it needs to be hydrophilic. Therefore, the hydrophobic tails point inwards while the hydrophilic heads point outwards.<span />
