The clear protein of an egg become opaque and firm when cooked because the heat CHANGES THE PROTEIN STRUCTURE BY DENATURING THE PROTEIN.
Each enzymes has its own range of temperature at which it remains active, when this temperature is exceeded the protein becomes denatured and loses its three dimensional structure which determines its functions.
Answer:
nitrogenous bases from the cytoplasm link up with an exposed complementary base
The answer is option A. Vaginal Fluids. HIV is commonly transmitted in two ways: sexual contact and injection with infected fluids such as blood. Through sexual intercourse, the person can get contact with the internal bodily fluids. Perspiration, saliva and tears cannot transmit HIV.
It will take 2273 h.
Here, the ideal gas equation is used.
<h3>What is the ideal gas law?</h3>
According to the ideal gas law, a gas's pressure is directly proportional to its volume and temperature.
where,
P = Pressure
V = Volume
n = No. of moles
R = Ideal gas constant
T = Temperature
Given,
V = 115.0 L
P = 1 atm
T = 273 K
I = 121 mA
R = 0.0821 atm. L/mol.K
Put the values in the above formula
The equation says,
2H⁺ + 2e⁻ → H₂
no. of electrons = 2
1 mol of the electron produces a 96500 C charge
5.13 mol of electrons will give = 5.13 × 2 × 96500
= 990,090 C
I = 121 mA = 0.121 C/s (1mA = 0.001 C/s)
We know,
q = It
where,
q = charge
I = current
t = time
t = q/I
t = 990,090/ 0.121
t = 8182562 s
t = 2273 h
Therefore, it will take 2273 h.
