The correct question is : The given statement is True or False
While studying a sample for height differences, researchers observed that the height of the participants varied significantly regardless of whether the participants' parents were short or tall. This suggests that the physical characteristic of height is most likely an example of Polygenetic inheritance.
Answer: True
Explanation:
The poly genetic inheritance can be defined as the characters which is not only controlled by the single gene in the body it is controlled by the multiple genes of the body.
The genes are large in quantity but the effect is very small. There are many characters in the body which is polygenic in nature.
These are height of offspring, skin color of the offspring, eye color of the offspring, et cetera.
Answer:
NO!!
Explanation:
During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA
Answer:
Potassium
Explanation:
Potassium is the major cation of intracellular fluid and is involved in the normal functioning of neurons and muscles. Adequate intracellular levels of potassium are also required for many vital metabolic activities.
Nerve and muscle cells need to balance the intracellular potassium ion concentration as relative concentrations of potassium ions in intracellular and extracellular fluid regulate their resting membrane potential. Increased extracellular concentration of potassium depolarizes these cells while its reduced levels cause hyperpolarization making the nerve cells and muscle cells non-responsive.
Similarly, heart cells need to maintain the potassium levels as its imbalance disrupts the electric conduction in the heart and may even cause sudden death. Being a part of buffer system of cells, potassium ions maintain the pH of body fluids.
