A) inducer
B) promoter
C) repressor
D) corepressor

Answers

The molecules that bind to a repressor so that the repressor no longer binds to the repressor operator

The repressor no longer binds to the operator?

The lac repressor protein binds to the operator and blocks the binding of RNA polymerase to the promoter and transcription of the operon. The promoter is the binding site for RNA polymerase, the enzyme that carries out transcription. The operator is a negative regulatory site to which the lac repressor protein binds.

With this information, we can conclude that the molecules that bind to a repressor so that the repressor no longer binds to the repressor operator.

Increase in Black moth population

During the indutrial revolution which was in the late 1800s the number of black moth increased and this was regarded as a direct consequence of air pollution during the industrial revolution. The evolution off the peppered moth into dark ( black ) moth was regarded as a evolutionary instance.

Hence we can conclude that a positive correlation to the increase in black peppered moth population is The correlation between air pollution and black moth predation.

The bones from an animal found at an archaeological dig have a C614 activity of 0.10 Bq per gram of carbon. The half-life of C614 is 5730 yr. What is the age of the bones?

Answers

C14 is an isotope used in radiocarbon dating techniques to date organic matter remains. The age of these bones is approximately 6890 years.

What is Carbon 14?

Carbon 14, also known as radiocarbon, is a radioactive carbon isotope.

Isotopes are the atoms of the same element -carbon- that vary in neutrons and, hence, in their massic number. They are alternative forms of the same element.

The radioactive C14 nucleus contains 6 protons and 8 neutrons and has a half-life of 5730 years.

The term half-life is a reference. It means that an organism that has been dead for 5730 years has half the C14 amount or concentration than the same organism had when it was alive.

Knowing the half-life of an element is useful to determine the age of the dead matter.

C14 is used in radiocarbon dating techniques or methods to estimate the age of fossils. This is a reliable technique used for dating organic samples that are less than 50,000 years old.

Available data:

The half-life of C14 is 5730 yearsBones activity of 0.10 Bq per gram of carbon

To answer this question we can make use of the following equation

Ln (C14T₁/C14 T₀) = - λ T₁

Where,

C14 T₀ ⇒ Amount of carbon in a living body. We know, by bibliography, that living organism activity is 0.23 Bq per gram of carbon. So, C14 T₀ = 0.23 Bq/gC14T₁ ⇒ Amount of carbon in the dead body. C14T₁ = 0.1 Bq/gλ ⇒ radioactive decay constant = (Ln2)/T₀,₅T₀,₅ ⇒ The half-life of carbon 14 = 5730 yearsT₀ = Time when the organism was aliveT₁ = Age of bones

Let us first calculate the radioactive decay constant.

λ = (Ln2)/T₀,₅

λ = 0.693/5730

λ = 0.0001209

Now, let us calculate the first term in the equation

Ln (C14T₁/C14 T₀) = Ln (0.1/0.23) = Ln 0.4347 = - 0.833

Finally, let us replace the terms, clear the equation, and calculate the value of T₁.

Ln (C14T₁/C14 T₀) = - λ T₁

- 0.833 = - 0.0001209 x T₁

T₁ = - 0.833 / - 0.0001209

T₁ = 6889.99 ≅ 6890 years

The bones are approximately 6890 years.
