Answer:
Older fossils are found in deeper layers of sedimentary rock.
Explanation:
The relationship between undisturbed sedimentary rock layers and fossils is that older fossils are found in deeper layers of sedimentary rocks.
This is one of the premise of the law of superposition and principle of fossil and fauna succession.
- An undisturbed sequence is one in which the sedimentary layers have been arranged sequentially.
- The oldest is at the bottom and the youngest on top.
- Also, fossils grade in this manner too.
- The oldest fossils will be in the oldest bed which is the deepest layer.
- The youngest bed will contain the youngest fossils in like manner too.

Answer:
The influenza virus has a negative sense RNA genome. In order to replicate, this means that the virus must first produce positive sense mRNA in order to produce necessary enzymes. Once the enzymes are translated, replication can take place. Positive sense cRNA is then made from the original negative sense RNA, using the enzymes. Negative sense RNA progeny are then made from the positive sense cRNA. The final viral progeny eventually bud from the host cell, ready to infect other cells.

structure; function
Explanation:
Cells are the fundamental unit of life. The plasma membrane consist of both lipids and protein. The main structure of the membrane is the phospholipid bilayer. the plasma membrane controls the movement of various molecules such as water, ion, amino acids, sugar into and outside the cell. The surface area of the membrane also regulates the exchange of membrane between the cell and its surroundings.
