Hi!the three-demnisonal (tertiary) structure of an enzyme is a single polypeptide chain "backbone".
Answer: a change in energy state occurs. The answer is dark or opaque - not able to be seen through.
Explanation:
The absorption of light makes an object dark or opaque to the wavelengths or colors of the incoming wave: Wood is opaque to visible light. Some materials are opaque to some wavelengths of light, but transparent to others. Glass and water are opaque to ultraviolet light, but transparent to visible light.
Answer:
C
Explanation:
polymerase Chain Reaction PCR is your answer 100%
Answer:
Choice C. Sodium bicarbonate acted as a pH buffer in Solution 2.
Explanation:
Sodium carbonate is used as pH buffering agent. Buffering agent is a type of solution which contains weak base or acid which stabilize the solution when another strong acid or base is added to the solution. If acid is added, the weak base that is present in the solution reacts with it and when base is added, weak acid reacts with it.
Answer:
<em> a) There is a 25% chance that their next child will be Rh-.</em>
<em>b) There is a 3/8 chance for a Rh+ girl</em>
Explanation:
As we know from the question that Rh is a dominant gene. A person having only one allele for the gene will show its effect as it is the dominant character.
This means that for a person to lack the Rh factor, it shall not have any allele with the Rh factor.
To illustrate the result, lets draw a punnet square:
Rh+ Rh-
Rh+ Rh+/Rh+ Rh+/Rh-
Rh- Rh+/Rh- Rh-/Rh-
For the probability for it to be a girl, we know that there are 50-50 chances for the next baby to be a boy or a girl. The chance of being Rh+ are 75% for the next baby.
Hence,
3/4 multiplied by 1/2 is 3/8 ,which is the chance for the next baby to be a girl with Rh+ factor.
