The structural level of protein least affected by disruption in hydrogen bonding is the primary level. Proteins are macromolecules and have four different levels of structure they are primary, secondary, tertiary, quaternary.Primary structure of the protein is formed by the covalent bond i.e., peptide bonds. hence, after disruption of hydrogen bond its structure will remain intact. Whereas secondary, tertiary and quaternary structure possess hydrogen bond.

July 21, 2021 at 9:30 pm in reply to: How much faster do ammonia (NH3) molecules effuse than carbon monoxide (CO) molecules? #10833::**Answer:**

Ammonia (NH_{3}) molecules effuse**1.28 times**faster than carbon monoxide (CO) molecules.**Explanation:**The kinetic molecular theory tells us that

Vrms = √(3RT/MW) where Vrms is the

*root mean square velocity*of an ideal gas. So Vrms is inversely proportional to MW and so will be the rate of effusion.Comparing NH

_{3}and CO we have:rate(NH

_{3})/rate(CO) = √MW(CO)/√MW(NH_{3}) = √28.01/√17.03 = 1.28rate(NH3) = 1.28 x rate(CO)

**Mendel’s law of independent assortment**states that the genes are separated and inherited independently of each other into the gametes. The**corn**can be used to study the law if independent assortment as each kernel of the corn is its fruit. Thus, it is a result of sexual reproduction.**OR**

**(i)**In case of corn, in addition to this there can be a pure line trait which can be found in corn.

**(ii)**However Mendel used**Garden pea**for his experiment ,we can use corn because it is**similar to character**with that of Garden pea.

(iii) While doing the experiment with corn we found out that there is independent and random assortment of the different gametes.July 19, 2021 at 4:14 pm in reply to: Why would it be hard to find the ideal CO2 level if the light intensity were very low? #10076::It would be difficult to find the ideal CO2 level with a low light intensity because

**the plant will have a difficult time trying to survive.**It would be very hard considering with no light there’s no reaction.

If the temp were extremely hot or cold, then oxygen production would be near zero no matter what light intensity value you use

In order to find the end behaviour of the graph, we need to find the degree of the given function and the leading coefficent.

Degree of the given function is the highest power of the variable.

We have variable x there.

Highest power of x is 6.

So, we can say:

Degree = 6 ( an even degree)

And leading coefficent is the coefficent of highest power term.

We have highest power term is 2x^6.

So, the leading coefficent is : 2 (Positive number)

For even degree and positive leading coefficent, end behaviour is

x –> ∞ f(x) = +∞

x–>-∞ f(x) = +∞

=> for x = – 4 , the y = 2 is the maximum value

hence ( – 4 , 2) is the**vertex**

hence every point on graph would be less than 2 on y – axis for any xIt goes through (- 6, 6), has a vertex at (- 4, 2), and goes through -2, 6).

not possible as y = 6 > 2It goes through (2, 6), has a vertex at (4, 2), and goes through (6, 6).

not possible as y = 6 > 2

it goes through (-6, -2), has a vertex at (- 4, 2), and goes through (-2, -2).

vertex (-4 , 2)

y < 2

This Could be her GraphIt goes through (2, -2), has a vertex at (4, 2), and goes through (6, -2).

not possible as vertex here is (4 , 2) instead of (-4,2)**Her Graph**On a coordinate plane, a parabola opens down it goes through (-6, -2), has a vertex at (- 4, 2), and goes through (-2, -2).
