A scientist is trying to determine the relationship between clams, snails, and squid. When she generates a molecular clock, she
is surprised to see that clams and squid are more closely related than clams and snails. Which did the molecular clock data show? Clams and squid have been evolving separately for a longer time than clams and snails.
Clams and squid have been evolving separately for a shorter time than clams and snails.
Clams and snails have more in common genetically than clams and squid.
Clams and snails are more similar in related structures than clams and squids.
The molecular clock refers to a procedure in molecular evolution that associate the time of divergence between the two species with the number of molecular differences determined between the sequences of DNA or proteins.
The more genetically associated, the shorter will be the separation time between the two species. Due to this, as clams and squid are more closely associated it can be concluded that these species look more genetically identical, and have evolved distinctly for a brief time duration in comparison to the clams and snails.

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. ... The denser cold liquid or gas falls into the warm areas.
Since , abductions, particularly the minimus and gluteus medius , are active on the side of the leg which is in contact with the ground . This is to avoid the tendency of gravity to cause the downward motion of the hip on the opposite side . In addition, the lateral muscle and paraspinal muscles of the trunk are active on the side of the swinging leg to avoid the downward motion of iliac crest on side .
genes are special instructions that come from an organism's parents. (sorry about repeating your question the minimum amount of letters and stuff i can type is 20.)
