Answer:A) form of gene

Explanation:

An allele is one of the different variants of a gene. It is one of the two or more genes found on the same locus on a chromosome which determines a specific trait in an organism. An allele can be dominant or recessive. A dominant allele is the allele that has the ability to mask the effects of a recessive gene when it is paired with the recessive gene while a recessive lacks the ability to express itself in the presence of a dominant allele. For a recessive allele to express itself, it must occur in a homozygous form.

Rescuers have just restored circulation to a 72 year old patient who was in cardiac arrest the patient's vital signs are b/p
Svetradugi [14.3K]
For vital signs in which the b/p is 112/170, P is 54, Resp. is 12, and patient is semi-responsive, the treatment to most likely benefit the patient would be to request for advanced life support (ALS) during the transport of the patient to the emergency department.

Advanced life support will allow for the intubation of the patient to administer certain medications to improve the patient's condition or prevent him/her from having another cardiac arrest. The patient should not be given nitro and should not be transported in prone position.

Answer:

I will have a greater increase in vasopressin secretion than my friend who donated blood.

Explanation:

Vasopressin, also known as Arginine vasopressin (AVP), Argipressin, or Antidiuretic hormone (ADH), is synthesized in the hypothalamus, and is released from the posterior pituitary gland, into the genreral circulation in response to a hypertonic extracellular fluid concentration. When a person looses a large volume of water from the body, from whatever cause, the blood becomes hypertonic, and the total volume of body fluids reduces (hypertonic, hypovolemic), in response to this change, ADH acts on the cells of the Distal Convoluted Tubule and Collecting Duct of the kidneys to reabsorb water into the blood, hence resulting in the excretion of a more concentrated urine with a reduced volume, this tends to return the tonicity of the blood towards the normal.

In the instances given in this example, when I lost 0.5L of sweat, which contains about 99% water, I loose more body water than my friend who donated blood with a total plasma volume of 0.5L, because plasma contains 92%, which is less volume of water than what I lost.
