Answer:

Reflex arc

Explanation:

The reflex arc is a special type of neural pathway which controls the reflex action or the immediate response to the stimulus in the organisms.

The reflex arc involves the receptor, the sensory neuron, the interneuron located in the spinal cord, the motor neuron and the effector's muscle. The action while controlled by the spinal cord also sends signals to the brain.

The reflex arc is an involuntary action that gets activated to the emergency condition like touching the hot plate, cold plate and sudden instance winch require immediate action.

Thus, the reflex arc is the correct answer.

The vaccine that may be administered to him at 14 years old is a dose of tetanus toxoid as this can present as pain from injection site. Since there is nothing said about the number of doses that he received, the patient should receive Tdap (tetanus, diphteria, and acellular pertussis) as stated from the Center of Disease Control and Prevention guideline for tetanus.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN
Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

  • <em>In any one species, the amount of adenine closely approximates that of thymine.  </em>
  • <em>In any one species, the amount of guanine closely approximates that of cytosine.  </em>
  • <em>The amounts of A, T, G, and C in DNA varies from species to species. </em>

<em>(options A, B and D)</em>

Explanation:

Organizing the data has to:

<u>Source of DNA      A            T            G            C </u>

Streptococcus    29.8       31.6        20.5       18.0

Yeast                   31.3        32.9       18.7         17.1

Herring                27.8       27.5       22.2       22.6

Human                30.9       29.4       19.9        19.8

E. Coli                  24.7       23.6        26.0      25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.
