Answer: A-T or G-C
Explanation:
The single-nucleotide polymorphism in human genomes is a substitution of a single nucleotide which occur in a specific position at the genome. The A-T nucleotide may appear dominant in the most population, while the remaining minor population may have the G-C nucleotide. The DNA molecule in the population at this site have A-T or G-C.
Answer:
Yes they should!

If the government wants to genetically modify food items, then people should know what it is they're eating. I hope this helps! :))

Explanation:
Pathogens are disease causing organisms in the body. They attack diverse cells, organs, tissues and systems in the body thereby causing them to malfunction (to become diseased).
Antibodies are the body's natural protective mechanism against pathogens. Antibodies engulf these pathogens and digest them. Then they produce certain chemicals called antitoxins which now destroy the toxins produced by these pathogens in the body.
Also they activate the systems involved in fighting pathogens by punching the cell wall of invading pathogens.
If you make a Punnett square, then you have all of the offspring having one dominant allele (the brown body color) and one recessive allele (the back body color).
Answer:
When a doctor strikes the child's kneecap:
- <em>The </em><em>sensory receptors </em><em>located in the tendon receive the stimulus.</em>
- <em>Information travels by </em><em>afferent pathway </em><em>through the sensory component of </em><em>motor nerve</em>
- <em>The integration center, in the </em><em>spinal cord</em><em>, receives the information and sends a motor response by </em><em>efferent pathway</em><em>.</em>
- <em>The </em><em>quadriceps contracts and extends the leg</em><em>.</em>
Explanation:
The patellar reflex —by hitting the kneecap tendon—is an example of a reflex arc, which produces the extension of the leg over the knee as an involuntary response to the stimulus to strike the patellar tendon.
This reflex has five main components:
- <em>Receptor.</em>
- <em>Sensitive fibers of a motor nerve (afferent pathway)</em>
- <em>Spinal cord integration center.</em>
- <em>Motor nerve fibers (efferent pathway).</em>
- <em>Effector.</em>
The reflex arc occurs because the stimulus received does not travel to the brain, but to the spinal cord, which causes the reflex response to be faster.
When the doctor strikes sensory neurons below the boy's kneecap, the following sequence of events occurs:
- The sensory receptors located in the tendon receive the stimulus.
- Information travels by afferent pathway through the sensory component of the femoral nerve.
- The integration center, in the spinal cord, receives theinformation and sends a motor response by efferent pathway.
- The quadriceps contracts and extends the leg.
The patellar reflex evaluates the integrality of the reflex arc at that level, whose synapse occurs between the lumbar segments of the spinal nerve L₂ and L₄.
