It is known that certain macroinvertebrates (small aquatic organisms) are sensitive to polluted waters. Stonefly larvae, for exa
zvonat [6]

Stonefly larvae, for example, are very sensitive to polluted water and low dissolved oxygen. You collect a lot of stonefly larvae in your study of a local stream and conclude that this stream has high levels of dissolved oxygen and is minimally polluted. Your conclusion is an example of deductive reasoning.

  • In both science and daily life, deductive reasoning is a sort of deduction. It occurs when you combine two genuine premises to arrive at a conclusion.
  • As an illustration, A = B. B and C are also equal. Deductive reasoning allows you to draw the conclusion that A and C are equal given those two statements.
  • Every dolphin is a mammal, Every mammal possesses kidneys.
  • You can draw the conclusion that all dolphins have kidneys through deductive reasoning. Keep in mind that for this to function, both assertions must be true.

A large population of laboratory rats was allowed to breed randomly for a number of generations. In this population, a dominant
ivann1987 [24]

Answer:

Frequency of heterozygous animals with agouti fur  is 42 %

Explanation:

As per the Hardy Weinberg's equation -

q^2 represents the frequency of population with phenotype expressed by homozygous recessive genotype

p^ 2 represents the frequency of population with phenotype expressed by homozygous dominant genotype

and 2pq represents the frequency of population with phenotype expressed by homozygous recessive genotype

Given -

q^2 = 0.49\\q = 0.7

As per first principle of Hardy Weinberg's equilibrium

p + q = 1

Substituting the value of q in above equation, we get -

p = 1- 0.7 \\p = 0.3

As per second  principle of Hardy Weinberg's equilibrium

p^2 + q^2 + 2pq = 1\\

Substituting the given values in above equation, we get -

0.09 + 0.49 + 2pq = 1\\2pq = 1 - 0.58 \\2pq = 0.42

Frequency of heterozygous animals with agouti fur  is 42 %

Which of the following options best depicts the flow of information when a gene directs the synthesis
valentina_108 [34]

The flow of <u>DNA → mRNA → protein </u>depicts the flow of information when a gene directs the synthesis of a cellular component.

Explanation:

Genetic information needs to flow in a specific pattern in order a gene to transform into a component like protein. This transformation takes place through the processes of transcription inside the nucleus and translation in the ribosomes. So the pathway: DNA → mRNA → protein will be correct flow of information for protein synthesis from DNA code. The mRNA or the messenger RNA encodes the genetic information or the chemical blueprint of the particular protein to be synthesized. This flow represents the central dogma of genetic information pathway or flow, which is; DNA encodes the RNA and the RNA encodes the Protein
