Archaea differ from bacteria in that archaea lack peptidoglycan.
<h3>
What about archaea and bacteria?</h3>
- Although archaea lack internal membranes, they do have a cell wall and swim by using flagella.
- The difference between bacteria and archaea is that bacteria have an ester-linked cell membrane, while archaea have an ether-linked cell membrane.
- Organelles and other internal membrane-bound structures are not present in the cells of bacteria and archaea.
- In contrast to eukaryotes, bacteria and archaea do not have a nucleus that separates their genetic material from the rest of the cell.
- Similar to Eubacteria, Archaea have a polysaccharide and glycoconjugate-rich cell wall.
- The strong cell borders that archaea form despite not having peptidoglycan make them resistant to high internal osmotic pressure.

The LEFT VENTRICLE of the heart supplies oxygenated blood to the aorta.
Aorta is the main artery that supplies oxygenated blood from the heart to other organs and tissues (except lungs, lungs are for gas exchange instead) so that they get enough oxygen and nutrients.
Meanwhile, the heart has 4 chambers, left and right atrium, and left and right ventricles. Atrium are for receiving blood from different vessels, and ventricles are for pumping blood out of the heart.
Since only the left ventricle is connected to the aorta, so, the answer should be left ventricle.

The glass with the alcohol will contain a mixture. This is because the melted ice will then be incorporated into the alcohol, creating a mixture of water and alcohol. However when the ice melts int he water, since ice is just frozen water, it the glass is still a pure substance because water is a pure substance and no other different substances have been added to it. <span />
Answer: D.
Explanation: Animal because animal cells are round and do not have a cell wall.
Hello there!
Part 1: At location 1, what is happening is the combustion of fossil fuels in factories and power plants to produce carbon dioxide (CO₂), which enters the atmosphere in the Carbon Cycle. This process started on a widespread scale in the Industrial Revolution with the invention of the steam machine. The reaction for the combustion of carbon is shown below:
C+O₂ → CO₂
Part 2: At this location, different types of energy transformation are happening successively. Considering that this is a power plant, firstly the potential chemical energy in the coal is transformed into thermal energy, this thermal energy is then transformed into mechanical energy by the action of the steam, and lastly, the mechanical energy is transformed into electrical energy in the generator.
Part 3: This process is a recycling of carbon in the carbon cycle because carbon that is transformed in this cycle eventually goes to carbon sinks (Fossil Fuels are carbon sinks). These carbon sinks sequestrate carbon and to return it to the atmosphere and recycling this carbon it is necessary to burn them in these factories. Thus, this is a recycling process in the carbon cycle.
Have a nice day!
