At first they grow downward in the direction of gravity. This is called geotropism. They also grow in the direction of humidity, water. This is called hydrotropism.
Answer:
The Growth rate constant (k) will be = per minute or 0.308 per hour.
Explanation:
Given,
N₀ = 4596 cells / ml
N = 206104972 cells / ml
t = 15 hours
We know that,
n =
Where,
n = no. of generation during the period of exponential growth.
∴ n =
=
= 3.3 × 44844.42
∴ n = 15.350
We know that,
g =
Where,
g = generation time
t = duration of exponential growth
∴ g = or ∴ g =
= = 15 / 15.350
= 900 / 15.350 ∴ g = 0.977 hours
∴ g = 58.63 minutes
We know that,
k =
Where, k = specific growth rate
∴ k = or ∴ k =
= 0.301 / 58.63 = 0.301 / 0.977
∴ k = per minutes ∴ k = 0.308 per hour
Platinum and gold is the answer . :)
Trees would be a renewable resource because we chop down trees and use seeds to regrow them.
Answer:
B
Explanation:
Hence When we eat food it closes but when we talk While eating the epiglottis would remain open and the food may enter windpipe which may trigger violent coughing to clear the food material out of trachea or may get serious by Chocking and may be fatal. That is why it is not advised to talk while eating
