The following provides the best argument for separating Archaea and Bacteria into their own domains instead of leaving them together in the single kingdom, Monera :
<u>It was discovered that they make their membranes differently and copy their DNA differently.</u>
Explanation:
The reason that Archaea were determined to be a separate kingdom so late was because archaea often completely resemble eubacteria. But you can see that fungi and other eukaryotes are more similar to archaea than the bacteria.
Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids
Bacteria: cell membrane contains ester bonds; cell wall made of peptidoglycan; have only one RNA polymerase; react to antibiotics in a different way than archea do
Archaea and bacteria are both prokaryotes, meaning they do not have a nucleus and lack membrane-bound organelles.
Both archaea and bacteria have flagella, thread-like structures that allow organisms to move by propelling them through their environment.
In all organisms, cell membranes are made of molecules known as phospholipids.
The phospholipids of archaea are unusual as they have membranes composed of glycerol-ether lipids, whereas bacteria and eukaryotes have membranes composed mainly of glycerol-ester lipids
Answer:
The correct option is Blood cells are produced in bone marrow.
Explanation:
Skeletal system can be described as the system which comprises of all the bones and joints of an organism. The main function of the skeleton system is to provide support and protection to the organism.
The circulatory system can be described as a system which comprises of the heart, blood vessels and blood. This system is mainly involved in the transportation of substances like oxygen, nutrients etc in the body.
The skeletal system interacts with many other systems of the body and helps them perform their functions. For example, the skeletal system interacts with the muscular system so that a muscle can contract and relax.
The skeletal system interacts with the circulatory system by producing blood cells in the bone marrow. Red blood cells, as well as white blood cells, are produced by this process.
Given what we know, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.
<h3>What are cyanobacteria?</h3>
These are tiny bacterial organisms. They were amongst the first organisms to use photosynthesis to sustain life. The sudden boom of cyanobacteria accounts for the rapid increase in oxygen given that they will use carbon dioxide to produce sugar through photosynthesis, expelling oxygen in the process.
Therefore, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.

What term describes a species whose removal would affect many other species, both directly and indirectly: keystone species
Explanation:
Cats should not eat onions, garlic, shallots, chives, or other foods that contain thiosulphate, a compound that can cause serious problems. When enough is eaten, the thiosulphate causes destruction of their red blood cells, a devastating condition called hemolytic anemia.
