Answer: Her speed is 4.4 m/s, and her velocity is 0 m/s.
Explanation:
Formulae :

Given: Length of track start to finish= 400 meters
After completing its 4 laps, total distance covered = 400 × 4 = 1600 meters
Time taken by Lila = 6 minutes
= 6 × 60 seconds [There are 60 seconds in 1 minute.]
= 360 seconds
Then, 

But from start to finish displacement = 0 m [displacement is the shortest distance between starting point to the finishing point]
So, 
Hence, Her speed is 4.4 m/s, and her velocity is 0 m/s.
Answer: The Principle of Original Horizontality
Explanation: The Principle of Original Horizontality states that layers of sediment are at first deposited horizontally below the movement of gravity. It is a relative relationship technique. The precept is critical to the evaluation of folded and tilted strata.
oxygen reacts with glucose in respiration
The Cell would go through interphase which is the division of cells.
Answer:
The cell membrane of the living organism is made of the lipid bilayer and proteins. The most common lipid present in the plasma membrane is the phospholipids.
Phospholipids has both the hydrophobic tail and hydrophilic head. The hydrophobic region interacts with each other. The lipid layer of phopholipids gets in association with the hydrocarbon chain of triglycerides. Their hydrophilic part dissolve in each other.
