What gives sperms motility​
Mandarinka [93]

Answer:

The tail of the sperm, the flagellum

Explanation:

We find cilia in the human body. They coat the epithelial cells of the upper respiratory tract and play a role in keeping dust particles, smog, and potentially harmful microorganisms from entering the lungs.

Their movements enable the movement of mucus or other substances across the surface of various epithelial cells. The cilia also cover parts of the male and female reproductive tract.  

Flagella are found in sperm, whose tail represents the flagellum in its structure. The body wall of the sponge, among others, contains cells with whips that create and maintain the flow of water through the body.

What is the daughter nucleus (nuclide) produced when 211 Pb undergoes beta decay by emitting an electron? Replace each question
poizon [28]
<h2>Daughter Nucleus</h2>

Explanation:

  • The original nucleus is known as the <em>parent nucleus</em>, and the core staying after the rot is known as the daughter nucleus
  • If a core radiates an alpha molecule, it loses two protons and daughter nucleus in this way, the little girl core has a nuclear mass of 4 less and a nuclear number of 2 not exactly the parent core
  • In β-decay, a neutron is changed over into a<em> proton, electron, and electron-anti neutrino</em>
  • Which builds the nuclear number of the nuclide by 1. <em>For 211Pb, this would bring about a nuclide of 211Bi.</em>
