During the process of replication, the double stranded DNA unwinds and parts itself by the action of enzyme called as Helicase. The unwinding or separation of DNA forms a replication bubble and at the edge of the replication bubble is the replication fork.
DNA replication starts at the point called as origin of replication or ORI at the replication fork. DNA polymerase is the enzyme that plays a key role in DNA replication. DNA continues to replicate until the entire new strand is not formed.
This is known as kin selection.
Behaviors which increase the reproductive success of genetic relatives increase the inclusive fitness of the individuals. If you have discussed Hamilton’s rule, recall that an allele will rise in frequency in the population over time if rb > c. Where r is the relatedness coefficient (to the relative benefitting from the behavior), b is the additional offspring that the relative has, and c is the personal offspring that are lost.
Answer:
cell Parts Analogy. The cell membrane controls what goes in and out of the cell. The cell membrane is like a screen door, because a screen door holds things out but lets air in.
Answer: cartilaginous
Explanation:
synarthrosis – There is little or no mobility. Most synarthrosis joints are fibrous joints (e.g., skull sutures).
amphiarthrosis – allows joints to have slight mobility.
diarthrosis – freely movable joints.
cartilagnious is cartilage type of strong stretchy tissue found in the joints.
Answer:
Being endothermic
Explanation:
Humans are not cold-blooded and we don't photosynthesise so only the second option applies to humans;
We produce heat internally within our bodies so we are endotherms, i.e. warm-blooded;
We shiver and have thermogenesis through metabolism to generate heat to keep body temp up and also sweating and physiological mechanisms to cool out bodies down.
