How is the location of the rough ER related to.its overall purpose for the cell

1 answer:

6 0

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Answer:

Lipid

Explanation:

Lipids are composed of a glycerol molecule bonded to long hydrocarbon chain(s) (can be single or multiple) and, depending on the lipid, to other molecules—such as a phosphate group (phospholipids). ... Fats Fats consists of glycerol and 3 fatty acids.

Answer:

A. Ice Ages

Explanation:

These periodic changes on Earth are a result of the five major ICE AGES that have occurred throughout Earth's history

The five major Ice Ages that throughout the Earth's history we're the following:

1. the Huronian: this occurred around 2.4 billion years ago

2. Cryogenian: this followed Huronian age, and it occurred around the period of 850 million years

3. Agondean-Saharan: this major ice age occur around 460 million years ago.

4. Karoo this is a period of about 360 million years

5. Quaternary is the present age, and it has been in existence since about 2.6 million years ago till the moment

Hence, in this case, the correct answer is Ice Ages

Explanation:

Red-shift

Emission spectra

Light from a star does not contain all the wavelengths of the electromagnetic spectrum. Elements in the star absorb some of the emitted wavelengths, so dark lines are present when the spectrum is analysed. Different elements produce different patterns of dark lines. The diagram shows part of the emission spectrum of light from the Sun.

Spectra from distant galaxies

Astronomers can observe light from distant galaxies. When they do this, they see it is different to the light from the Sun. The dark lines in the spectra from distant galaxies show an increase in wavelength. The lines are moved or shifted towards the red end of the spectrum. This effect is called red-shift. The diagram shows part of the emission spectrum of light from a distant galaxy.

Red-shift and speed

Astronomers see red-shift in virtually all galaxies. It is a result of the space between the Earth and the galaxies expanding. This expansion stretches out the light waves during their journey to us, shifting them towards the red end of the spectrum. The more red-shifted the light from a galaxy is, the faster the galaxy is moving away from Earth
