According to Bronsted-Lowry acid concept
an acid is a that donate a proton" and a base is a "proton acceptor."so
will look for that molecule to which <span>H2O</span> "donates" H+to become <span>OH−</span>. so answer will be..
. <span>NH3+H2O→NH+4+O<span>H<span>−
so correct option is NH3
hope it helps</span></span></span>
Answer: a.Camouflage
Simulation is a deception in the characteristics of the organism which favors it's survival in the environment. Camouflage is a kind of simulation, in which the organism adapt the color or shape according to the surrounding environment in order to remain undetected by a prey and a predator. For example, chameleon is a reptile, which can change it's color according to the surrounding environment. It changes it's color to green in grass and remains brown in the tree bark in order to eat insects and remain undetected from prey and predator population.
Therefore, According to the simulation, camouflage helps predators to survive by allowing them to sneak up on their prey.
Answer:
The correct answer is 20 years.
Explanation:
It is given that the growing rate is 2% or 2/100 = 0.02
This rate got increased to 150%
The formula for exponential growth is:
A = Pe^rt
Let the initial population be 100%
150 = 100.e^0.02*t
3/2 = e^0.02t
1.5 = e^0.02t
After taking log from both the sides:
ln(1.5) = 0.02t * ln(e) [ln(e) = 1]
ln(1.5) = 0.02t
t = ln(1.5)/0.02
t = 20.27
Thus, it will take around 20 years for the size of the population to reach 150 percent of its present size on the basis of the exponential growth function.
It controls all the involuntary actions like digestion and beating of our heart
