Answer:
All the options are true except option D.
Explanation:
Archaea are a group of prokaryotic organisms i.e. they lack a membrane bound nucleus. They are one of the the three domains of life (the other two being bacteria and eukarya). Archeans possess a cell wall like bacteria but it is not composed of peptidoglycan, like bacteria cell wall.
Archeans are generally known to be found in very severe environmental conditions, hence, they are referred to as extremophiles e.g Some are thermoacidophiles i.e. thrive in very hot and acidic environment while others are extreme halophiles i.e. thrive in salty regions. Archeans known as methanogens produce methane gas as a product of metabolism from carbon dioxide and hydrogen.
However, the domain archeae was only found to be in existence recently after the domain bacteria, hence, they are not considered to evolve before the domain bacteria.
Well the definition in an actual dictionary or scientific book is quite confusing, so to put it simply:
A chromosome is a DNA molecule with part or all of the genetic material of an organism.
If that makes any sense.
That’s really as simple as I know it.
Chromosomes are complex, so a simple definition doesn’t come easy.
Happy to help!

Answer is: the part of an experiment that stays the same though out the experiment is constant.
<span>Constant is a quantity that does not change.
</span>Experimental variable<span>, which is the also part of an experiment, is affected by the experiment (have change).</span>
<span>D. can grow as the animal grows. Endoskeleton is an internal skeletal system that provides a framework for the body. Unlike an exoskeleton, it grows as the body grows. </span>Humans, birds, fish and mammals have endoskeletons.
Vitamin C is the water soluble vitamin that can regenerate vitamin E after it has been oxidized. Because vitamin C is an acid, it is reasonably stable in acidic solutions, but in neutral or basic solutions it is easily and rapidly oxidized by dissolved oxygen. The oxidation of vitamin C, Ascorbic acid, is brought about by the loss of two hydrogen atoms as the vitamin is converted to dehydroascorbic acid. Vitamin C functions as antioxidant, assists in synthesis of collagen, a component of the connective tissue, synthesis of DNA, bile, neurotransmitters, thyroid and other hormones.
