When examining the transmission of phenylketonuria (PKU), a recessive trait, we can clearly identify the <u>genotype </u>when a child is afflicted with PKU. For the child not afflicted with PKU, we can only identify the <u>phenotype</u>, as the child may or may not be a carrier.
An organism's genotype is its particular aggregate of alleles for a given gene. So, for example, in the pea plants above, the feasible genotypes for the flower-color gene were pink-purple, red-white, and white-white. The phenotype is the bodily manifestation of an organism's allellic combination (genotype).
Someone's genotype is their precise sequence of DNA. Greater specifically, this term is used to consult the two alleles someone has inherited for a selected gene. Phenotype is the detectable expression of this genotype – a patient's scientific presentation.

Constant speed would have a straight and diagonal line either facing upwards or downwards in the graph. This is because speed is displacement divided by time, which becomes the slope of the graph.
Answer:
<h2>Gray matter: the gray matter is arranged intohorns: The posterior horn extends towards the dorsal root, the anterior horn extends towards the ventral horn, and the lateral horn lies between the posterior and anterior horns.
</h2>
Explanation:
The posterior horn is associated with the sensory nerve cells, the anterior horn is associated with the somatic motor neuron, and the lateral horn associated with the ANS ( autonomic nervous system).
Posterior horn:
Sensory neurons pass through the dorsal root ganglion after that the dorsal root and in the gray matter the neurons synapse to inter neurons in the posterior horn or may continue to the white matter and then enter the spinal cord.
Anterior horn:
The motor portion of the nervous system has two parts; i) the somatic motor system and the ii) autonomic nervous system. The somatic motor neuron stimulates the skeletal muscle with stimulation. The somatic motor neuron cell bodies (part of verve cell) are in the anterior horn of the gray matter.
Lateral horn:
The autonomic motor neuron send stimulation to smooth muscle, cardiac muscle, and glands etc. The cell bodies( part of nerve cell) of the autonomic motor neuron are in the lateral horn of the gray matter.
<span>Homeostasis Body's tendency to maintain a steady internal state; physiological equilibrium or balance around an optimal set point. [hot=sweat, cold=shivers]
Janice sweating on the treadmill in order for her body to cool off is an example of Homeostasis. Homeostasis is the body's ability to keep a steady internal temperature, state, equilibrium or balance around the ideal set point. This means when you are hot, you sweat to cool the body down and when you are cold your body shivers to help warm it up.</span>
Phytoplanktons are also called microalgae. They are the foundation of the aquatic food web and the primary producers. They feed everything from microscopic to multi-ton whales. Thus, the answer to the question above is letter B. Provide basis of food chains.
