The doppler effect and redshift.
Nataliya [291]4 years ago

Answer:

The correct answer is red shift and Doppler effect.

Explanation:

The Doppler Effect was used by Hubble to demonstrate that the universe was expanding. According to the effect, the light from the far-off galaxies was shifted towards the lower frequencies, that is, towards the red end of the spectrum. This is known as the Red-shift or the Doppler shift.  

It was in 1925, Edwin Hubble witnessed Red-shift. He observed that the redshift of galaxies was directly equivalent to the distance of the galaxy from the Earth. This signifies that the things distant away from the planet Earth was moving away at a quicker rate, and thus, it can be concluded that the universe is expanding.

Question 9
IRISSAK [1]

Answer:

<u>O floating around one another in a fluid structure</u>

<u />

Explanation:

Cells are made up of varying types of molecules in order to achieve a fluid, stable plasma membrane. The membrane mainly consists of:

  • lipids
  • proteins
  • cholesterol

Lipid membranes help maintain selective membrane permeability. The lipids, formed from glycerol and saturated/unsaturated fatty acids, are made up of polar heads and non-polar tails; they typically only allow the movement of <em>small non-polar molecules</em>. Larger molecules are <em>transported </em>through integral proteins; other types, are peripheral, and may have specialized functions like <em>cell signaling</em>.

Cholesterol molecules keep the lipids in place, and ensure membrane fluidity.  In extreme temperatures, they help the membrane to maintain its shape without becoming too rigid.
