Answer:

The possible genotypes of a man with blood type B are BB or BO and the genotype of a woman with blood type AB is AB. The child would receive an A allele or a B allele from the mother and a B allele or an O allele from the father. Therefore, the child could not possibly be of blood type O.

Describe the profile you would expect for a biological catalyst. Complete the sentences to explain why an enzyme is different th

uysha [10]

Answer:

- When looking at the plot G versus reaction coordinate, the profile for a biological catalyst (e.g. an enzyme) will have <u>about the same</u> transition state(s), with an overall activation energy that is <u>low </u>in comparison to the uncatalyzed reaction.

- Enzymes have a <u>high </u>molecular weight and are <u>organic</u> compounds, while inorganic catalysts often have a <u>low</u> molecular weight and are <u>inorganic</u> compounds.

- When comparing rates, enzymes are typically several times <u>faster</u> than inorganic catalysts.

Explanation:

Enzymes are organic molecules capable of producing a faster chemical reaction. In an enzymatic reaction the transition state -corresponding to the state in which the substrates or products are equally likely- tends to be the same, while the energy required for the reaction decreases.

The differences between an enzyme and an inorganic catalyst are structural and functional:

<em>Enzymes are organic and of high molecular weight and catalysts are inorganic and of low molecular weight. </em>
<em>An enzyme can change its structure during a reaction, while the configuration of a catalyst is the same. </em>
<em>The reaction catalyzed by an enzyme is about 10⁶ to 10¹² times faster than with a catalyst.</em>

How much of a 2.0 M NaCl solution is needed to make 205.0 mL of 0.15 M NaCl solution?

svetlana [45]

Answer:

To relate the volume and molarity of a solution at two different concentrations, the expression used is :

M₁V₁ = M₂V₂

(2M) V₁ = (0.15M)(250ML)

V₁ = 18.75

What will be the volume of a balloon at 98 kPa if its volume is 9.65 L at 235 kPa?

OlgaM077 [116]

<span>Boyle's Law or Boyle-Mariotte's Law: Under constant temperature, the volume occupied by a given fixed mass of a gas is inversely proportional to its pressure.

Formula:
</span> $\frac{ P_{1} }{ P_{2} } = \frac{ V_{2} }{ V_{1} }$
Product of extremes equals product of means
$P_{1} * V_{1} = P_{2} * V_{2}$

Data:
$P_{1} = 235\:kPa$
$V_{1} = 9.65\:L$
$P_{2} = 98\:kPa$
$V_{2} = ?$

Solving:
$P_{1} * V_{1} = P_{2} * V_{2}$
$235*9.65 = 98*V_{2}$
$2267.75 = 98V_{2}$
$98V_{2} = 2267.75$
$V_{2} = \frac{2267.75}{235}$
$\boxed{\boxed{V_{2} \approx 23.14\:L}}\end{array}}\qquad\quad\checkmark$

Which of the following situations best shows deposition?

KATRIN_1 [288]

Answer:

chemistry, deposition occurs when molecules settle out of a solution. Deposition can be viewed as a reverse process to dissolution or particle re-entrainment. It is a phase change from the gaseous state to a solid, without passing through the liquid state, also called re-sublimation.

Explanation:

Examples include beaches, deltas, glacial moraines, sand dunes and salt domes. In severely cold temperatures frost will form on windows because the water vapor in the air comes into contact with a window and immediately forms ice without ever forming liquid water.
