Answer
Gametes that fertilize an ovum are called the sperms
Explanation
The reproductive cells of an organism are called the gametes or sex cells. Female sex cells are the ova/egg where as male sex cells are the sperms. The sperms are stored in the scrotum after their production in the male testes where as the eggs for females mature in female ovaries. During fertilization, sex cells meet in the Fallopian tube.
Protons- these have a positive charge
Electrons-negative charge
Neutrons- neutral charge
Answer: 9.2 g/cc
Explanation: density = mass/vol = 9.66/1.05 = 9.2
Children who have had cancer and undergone radiation to their head may experience permanent hearing loss.
Radiation therapy is increasingly being used on head and neck tumors, and close to 100% of the radiation delivered may reach the structures of the auditory system.
Based on selective permeability, if the pores in the dialysis tubing were too small to allow iodine potassium to pass through, the liquid in the tubing would not turn black.
<h3>What is Selective permeability</h3>
Selective permeability refers to the ability of a membrane to allow some molecules to pass through it but no others.
In the dialysis tubing, selective permeability is used to remove some substances but not others.
The selective permeability of the dialysis tubing depends on the pore size.
When a dialysis tubing containing starch solution was dipped into a beaker containing iodine, the solution in the tubing turned black due to the ability of iodine molecules to pass through the membrane.
However, if the pores in the dialysis tubing were too small to allow iodine potassium to pass through, the liquid in the tubing would not turn black.
