<span>During the tracheoesophageal puncture process a prosthesis is inserted into the trachea. This procedure is used to help patients find their voice. Things such as throat cancer, or laryngeal cancer may cause patients to lose their voice and main form of communication. With a tracheoesophageal puncture it gives patients a new way to communicate with others, through a vibratory signal.</span>
6) Vessels maintain blood flow because they: [D. Depend upon body movement], especially veins of the lower extremities.
7) Kidneys regulate water volume in the blood and urine [A.], thereby affecting the volume of blood, which directly relates to pressure and flow.
8) Stronger striated muscle [D.] is a health benefit of exercise which only affects skeletal muscle, not the heart muscle (cardiac) nor blood vessels (smooth).
9) [D.] Drinking liquids immediately before a blood pressure (BP) reading would be least likely to raise BP artificially. Where as exercise, fear or anxiety, and an improper cuff size could affect the BP measurement.
Answer:
A large number of organisms are supported by the soil. Living Organisms present in the soil are archaea, bacteria, actinomycetes, fungi, and algae. Ants, earthworms and nematodes, are other organisms that are found in soil. They all are important for the environment as they bring transformations in the soil which are important for life. They also impact the chemical and physical properties of the soil, these properties are studied by the soil biologists.
Answer:
2. The gene responsible for eye color is on the X chromosome.
Explanation:
<em>For X-linked genes, a male can either be affected or unaffected because the Y chromosome is hypothesized not to carry any gene. Females on the other hand can be a carrier, affected or unaffected because the two sex chromosomes carry genes.</em>
If eye color allele in drosophilia is represented by R, the cross between F1 red-eyed heterozygous female and red-eyed males can be illustrated below:
Red-eyed heterozygous female =
Red-eyed male =
x
Progeny:
Out of the 2 male progeny from the cross, 1 () is white-eyed while the remaining one () is red-eyed
Hence, the result shows that the gene for eye color in Drosophilia is X-linked.
Option 2 is the correct answer.
Answer:
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.
Explanation:
