Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.
Infrared spectroscopy helps to identify the atoms and molecules in the object.
The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.
The Doppler shift enables astronomers to discover extrasolar planets.
As a planet orbits its star, the star is alternately moving away from or toward us.
Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.
Explanation:
Answer:
diverse proteins embedded in a phospholipid bilayer
Explanation:
According to fluid mosaic model the cell membrane is made of bilayer of phospholipid. Many proteins are embedded in this bi layer. Carbohydrate and cholesterol are also found in different forms. Carbohydrate can either be attached to the embedded protein in which case it is called as glycoprotein or it can be connected to the lipid molecule in layer and called as glycolipid.
Proteins can be found in two forms too. They can either be embedded in the layer i.e. they can penetrate single or both layers. These proteins are called as integral proteins. They can also be present on one side of the membrane and not penetrate the lipid bilayer in which case they are called as peripheral proteins.
B. It was an explanation for how the earth originated.
No it is not balanced because there are four oxygen atoms in H2SO4 while there 5 oxygen atoms in the reactants side
