Answer:DNA, RNA, Ribosomes and Protein Synthesis

This provided the first substantial evidence for the endosymbiosis hypothesis. It was also determined that mitochondria and chloroplasts divide independently of the cell they live in.

Explanation:

What role did endosymbiosis play in the evolution of eukaryotes? Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts. This kind of natural selection led to the evolution of eukaryotic cells and the plants and animals we see today.

Where do most of the world's coal mines come from?

Sonja [21]

Answer:

Most of the world's coal mines come from China, India, the United States, the European Union, and Australia.

Explanation:

China: In the year 2018, China alone produced approximately 3523 million tonnes of coal. Though China is the largest producer of coal in the world, it has to import coal from other countries to fulfill its energy needs. China's share in the total coal produced in the world in the last 12 years is 39.7%.
India: The production of coal in India reached approximately 716 million tonnes in the year 2018. The total amount of coal produced in India in the last 12 years makes up 7.5% of the coal produced all over the world.
The United States: The coal produced in the United States in the year 2018 was approximately 702 million tonnes. The last 12 year share of the coal produced in the US is 16.2% of the total coal produced all over the world.
The European Union: The countries that constitute the European Union togetherly produced approximately 490 million tonnes of coal in the year 2018. The last 12-year contribution of the EU to the total coal produced in the world is 9.2%.
Australia: The production of coal in Australia for the year 2018 was approximately 481 million tonnes. Australia alone produced 6.2% coal of the total world production of coal in the last 12 years.

If the density of ethanol is 0.789 g/mL, how many milliliters are produced in this reaction?

yarga [219]

The volume of the ethanol is 6.7 mL

<h3>What is the density of the ethanol?</h3>

We know that density is defined as the ratio of the mass to the volume of an object. We know that the density is said to be an intrinsic property and this means that we can use the density of the object to be able to obtain the kind of object that we are dealing with.

We have the information that the mass of the carbon dioxide that can be obtained from the reaction is about 10 g. We can now use this to obtain the number of moles by the use of the formula;

Number of moles = mass/ molar mass

= 10 g/44 g/mol

= 0.23 moles

From the reaction equation:

1 mole of ethanol produces 2 moles of carbon dioxide

x moles of ethanol produces 0.23 moles of carbon dioxide

x = 0.23 × 1 /2

= 0.115 moles

Mass of ethanol = 0.115 moles × 46 g/mol

= 5.29 g

Volume of the ethanol = mass/density

volume = 5.29 g/0.789 g/mL

= 6.7 mL
