Which behavior can reduce pollution that occurs due to the use of coal?
mixas84 [53]

Answer:

A

Explanation:

Coal is majorly used to produces electricity. The coal is ignited and the heat produced used to heat water to steam. The steam is then used to drive turbines with a dynamo effect to produce electricity. Turning off lights when not in use reduces the demand for electricity hence reducing the amount of coal needed to meet this demand.

Other ways to conserve energy is using bulbs with low energy demand - such as LEDs - and  improving natural lighting indoors.

Which three statements correctly describe the endoplasmic reticulum?
Sunny_sXe [5.5K]

I have searched everywhere, but I have not found the proposals of the question, but I will explain to you what is the endoplasmic reticulum so that you can answer it.

The endoplasmic reticulum is a eukaryotic organelle located in the cytoplasm.

The endoplasmic reticulum is a network of membrane tubules (often interconnected) scattered throughout the cytoplasm of eukaryotic cells. Its membrane, which alone represents more than half of the cellular membrane system, is in contact with the nuclear envelope.

The endoplasmic reticulum can be:

Granular (or rough) (RER) that is to say associated with ribosomes.

Smooth (SER).

The granular endoplasmic reticulum is the place of synthesis (in the associated ribosomes) of the proteins secreted outside the cell and of the proteins and lipids constituting the membranes of the cellular organelles. Golgi, lysosomes, mitochondria, nucleus, ribosomes, vesicles ...). It participates in the correct folding of the proteins that have just been synthesized.

The smooth endoplasmic reticulum participates in cellular metabolism, synthesizing lipids and storing calcium.
