Answer:
Unlike the queen bee, which has 32 chromosomes, drones have half the chromosomal charge (n= 16), so they are considered haploid.
Explanation:
The system of determination of the sex in the bees —like in other insects— is called haplodiploidy, and consists of which the females of the species possess complete charge of chromosomes, whereas the males only possess half. This is what happens with the queen bee with 32 chromosomes, while drones only have 16 chromosomes, so they are considered haploid.
Additionally, as a characteristic of haplodiploidy, males only proceed from female gametes, so they can only contribute gametes to produce females of the species.
The other options are not correct because:
- <em>Drones, with half of the chromosomal charge, </em><u><em>cannot be diploid</em></u><em>.
</em>
- <u><em>Monosomy and trisomy</em></u><em> are defects in the distribution of chromosomes during meiosis, which imply one chromosome less or one chromosome more in the normal chromosome charge respectively.</em>
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.

Binocular vision. Binocular vision is vision with two eyes, and the main cue for depth perception associated with binocular vision is retinal disparity. ... The disparity (difference) between these two retinal images (retinal disparity) can be used as a cue for depth/distance.
