Answer:

To show that both are evolved from a common ancestor.

Explanation:

It make the comparison between humans and chimps because the two species are so closely related to each other. Humans an chimps evolved from a single ancestor species about six or seven million years ago. Humans and chimps gradually evolved from a common ancestor due to environmental conditions that change their DNA which passed from generation to generation and bring changes in their shape and appearance as well.

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>

________ allow materials to be exchanged between the blood and tissues, ________ carry blood towards the heart, and ________ car
Anuta_ua [19.1K]

Answer:

b.  Capillaries; veins; arteries

Explanation:

Capillaries are the blood vessels with very thin walls. They serve as a site for an exchange of substances such as respiratory gases, nutrients, and toxins between the blood and the cells of the tissues. Veins are the blood vessels that mostly pick the deoxygenated blood from the body cells and deliver it to the heart for oxygenation. On the other hand, arteries are the blood vessels that mostly carry the oxygen-rich blood. They pick the oxygenated blood from the heart and deliver it to body cells. Therefore, veins carry blood towards the heart while arteries carry it away from the heart.

Which of the following functions does active transport perform in a cell ?
viktelen [127]

Answer:

To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells.
