Answer:
D. Discovered chemolithotrophs in natural enviroments.
Explanation:
Sergei Winogradsky was a russian microbiologist. He observed in his research with genus of bacteria <em>Beggiatoa, </em>they were able to oxidize hydrogen sulfide as an energy source. Being the first example known of lithotrophs (organisms that use inorganic substrate in order to obtain energy).
Increased exposure to X-rays
Answer:
The endoderm gives rise to the nervous system.
Explanation:
Gastrulation is the process that occurs during the third week of embryonic development and includes transformation of embryonic disc with epiblast and hypoblast into a three layered embryonic disc made up of ectoderm, mesoderm and endoderm. These are the three primary germ layers and give rise to various tissues and body organs.
Endoderm of the embryo give rise to epithelial lining of gastrointestinal tract (except the buccal cavity), respiratory tracts and other organs such as gallbladder, liver,etc. Mesoderm forms connective tissues such as bones as well as muscles and peritoneum. All the tissues of nervous system and epidermis of skin are derived from ectoderm.
According to the research, all of the following are typical physiological effects of dehydration except <u>osmolality decreased</u>.
<h3>What is dehydration?</h3>
It is the process that refers to eliminating or losing the water that is part of the composition or that contains an organism.
Among the most frequent effects are thirst, osmolality increases, increased sweat rate, dry skin and fatigue.
Therefore, we can conclude that according to the research, all of the following are typical physiological effects of dehydration except osmolality decreased.
