Answer:

B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system by secreting antibodies. In mammals, B cells mature in the bone marrow, which is at the core of most bones.

What specific changes in rachel’s muscle cells and kidney function are leading to elevated plasma k levels?
tensa zangetsu [6.8K]

Intracellular Potassium Shifts and Impaired Potassium Excretion leads to elevated plasma K levels.

What is Hyperkalemia?

  • Hyperkalemia, a potentially lethal condition, develops when serum potassium levels rise above 5.5 mmol/l.
  • Potassium is the most common intracellular cation and is crucial for many physiological functions, at a concentration of 100-150 mmol/l. The digestive system quickly and usually fully absorbs potassium.

Causes:

  • Increased Potassium intake: In adult patients with normal renal function, increased dietary potassium intake is a very rare cause of hyperkalemia, but it can be a significant factor in people with kidney disease.
  • Intracellular Potassium Shifts: Large amounts of intracellular potassium can be released into the extracellular area as a result of cellular damage. Excessive activity, rhabdomyolysis after a crush injury, or other hemolytic processes can all be to responsible for this. 
  • Impaired Potassium Excretion: The most frequent cause of hyperkalemia is acute or chronic renal disease. Hyperkalemia may also result from tubular dysfunction brought on by aldosterone insufficiency or insensitivity.

A car with a mass of 1,324 kilograms, traveling at a speed of 20 meters/second, crashes into a wall and stops. What is the kinet
Leto [7]

The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

<h3>How to calculate kinetic energy?</h3>

The kinetic energy of a moving car can be calculated using the following formula:

K.E = ½ × m × v²

Where;

  • K.E = kinetic energy
  • m = mass
  • v = velocity

K.E = ½ × 1324 × 20²

K.E = 264800J

Therefore, the kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

Sexual reproduction allows for
bekas [8.4K]
Greater genetic diversity, compared to asexual reproduction.

If you think about it, this makes sense because in asexual reproduction, an organism reproduces all by itself, and uses its own genome as the blueprint for its' offspring. However with sexual reproduction, two organisms come together, each contributing half the required chromosomes, and the offspring gets 1/2 it's genes from the mother and 1/2 it's genes from the father. Sexual reproduction allows for greater diversity because it doesn't just rely on mutations to add new diversity to the genepool.
