We use a prison as an analogy for this. If the gate is open, the prisoners can easily or freely leave the prison cell. This will represent passive transport. In order to get prisoners in the cell, you have to put force on them and this will be active transport.
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:
Two substances which are selectively reabsorbed from the tubules of a nephron are Amino acids and Glucose.
Explanation:
The majority of the vital nutrients (which do not have to be discharged out) are recovered by the bloodstream out from tubule of the nephron all through re - absorption, a key procedure in urine production that primarily takes place in the PCT of the nephron. Proximal tubule includes unique cuboidal epithelial cells having microvilli towards the lumen for completing this. Higher substance reabsorption is a result of this. Because glucose and amino acids seem to be essential to the organism, hence the nephron's tubules reabsorb them. Moreover, sodium, water and other ions like sodium can also be reabsorbed by nephrons. Furthermore nephron tubules are in charge of waste product elimination and nutrient absorption.
