kobusy [5.1K]2 years ago

The correct answer is D

The process of evolution presents a change in population genetics over periods of time. Therefore, it's important to remember that we can only observe the evolution by looking at the level of the population, not on the level of an individual organism.

Evolution works trough 4 evolutionary mechanisms that change the frequency of an allele in a population, leading to evolutionary change of that population and later even species. These mechanisms are : mutations, genetic drift, gene flow and natural selection.

<span>Evolution can best be summed up by statement D - change in a population through genetic variation over time. The other statements do not refer to evolutionary changes, as these are changes that occur slowly, rather than suddely or with speed.</span>

Question 4 (Multiple Choice Worth 3 points)
sweet-ann [11.9K]

The creation of DNA fragments with ends that can join with other DNA is achieved by the use of restrictive enzyme analysis.

<h3>What are restriction enzymes?</h3>

They are enzymes utilized in genetic engineering or gene recombination technology to cut DNA at some specific points in other to have sticky ends.

The sticky ends DNAs are able to join with other DNAs using these ends. Another enzyme (Ligase) is utilized to join the DNA back once the desired DNA has been inculcated.

Which of the statements about half-life are true?
Oksana_A [137]

The statements which are true about half-life are given below:

  • A radioactive element's half-life stays the same when its temperature changes.
  • A radioactive element's half-life stays the same when the pressure upon it changes.

Thus, the correct options are B and F.

<h3>What is Half-life?</h3>

The half-life of any radioactive element may be defined as the time taken for the radioactivity of a specified isotope to drop to half of its original value.

The above statement is true about the half-life of any radioactive element because the half-life of any substance does not depend on pressure, temperature, and concentration.

Therefore, it is well described above.

Determine the nature of the expression of the lacZYA genes, represented by L, and label each genotype as constitutive, inducible
VladimirAG [237]

Answer:

Explanation:

Symbol          Representation

I-                     laci mutant cannot bind to the operator

Is                    laci mutant always bind to the operator

OC                 Operator mutant that prevent repressors binding

F’                    the wild type operator, O+, and laci gene on a plasmid

L                     lacZYA genes

I+ O+ L+   Inducible

I+ OC L+   Constitutive

I+ OC L+, F’   Constitutive

I- O+ L+, F’   Inducible

Is O+ L+    no transcription

Is O+ L+, F’   no transcription
