castortr0y [4]3 years ago
5 0

Answer:

The absence of estrogen may lead to many symptoms:

  1. Irregular periods
  2. Anovulation, and therefore, infertility
  3. Hot flashes
  4. Decreased vaginal lubrication, which can lead to painful intercourse
  5. Depression, because estrogen stimulates serotonin release
  6. Osteoporosis and bone fractures
  7. Weight gain

Usually the treatment for low estrogen levels is hormone replacement therapy (orally, vaginally or topically)

A Typical Human Body Contains About 3.0 Grams Of Potassium Per Kilogram Of Body Mass. 1. ... 1. How much Potassium-40 is present
Studentka2010 [4]

Answer:

Given

Per Kg of body mass, there is 3 gram of potassium

And abundance of three isotopes are as follows

Potassium-39, Potassium-40, and Potassium-41. Have abundances respectively as 93.26%, 0.012% and 6.728%.

1) A body weighing 80 Kg will have 240 grams of potassium. And the amount of Potassium-40 will be 0.012% of 240 gram

= 240*0.012/100 = 0.0288 gram.

2) Dose in (Gy) = (energy absorbed)/(mass of the body) = ( 1.1*106*1.6*10-19)/(80) = 22*10-10 J/kg

Dose (in siverts) = RBE*Dose(in Gy) = 1.2*22*10-10 = 26.4*10-10

A dendritic cell is a(n)
brilliants [131]

Answer:

b) blastic red blood cell (RBC).

Explanation:

In excess of 340 blood group antigens have now been described that vary between individuals. Thus, any unit of blood that is nonautologous represents a significant dose of alloantigen. Most blood group antigens are proteins, which differ by a single amino acid between donors and recipients. Approximately 1 out of every 70 individuals are transfused each year (in the United States alone), which leads to antibody responses to red blood cell <u>(RBC) alloantigens</u> in some transfusion recipients. When alloantibodies are formed, in many cases, RBCs expressing the antigen in question can no longer be safely transfused. However, despite chronic transfusion, only 3% to 10% of recipients (in general) mount an alloantibody response. In some disease states, rates of alloimmunization are much higher (eg, sickle cell disease). For patients who become alloimmunized to multiple antigens, ongoing transfusion therapy becomes increasingly difficult or, in some cases, impossible. While alloantibodies are the ultimate immune effector of humoral alloimmunization, the cellular underpinnings of the immune system that lead to ultimate alloantibody production are complex, including antigen consumption, antigen processing, antigen presentation, T-cell biology.

Who performed the first successful split brain surgery to prevent the spread of seizures in the brain?
kompoz [17]

Answer:

Michael Gazzaniga and Roger W. Sperry

Explanation:

Split-brain also known as callosal syndrome was considered successful after it had passed three types of tests to analyze the range of cognitive capabilities of the split-brain subjects. The first was the visual stimulation ability test, the second test was a tactile stimulation situation and the third tested the auditory abilities of the patient.
