Answer:
(B) resemble structures formed by bacterial communities that are found today in some shallow marine bays.
Explanation:
Extant stromatolites represent real "living fossils" for they are decendents of ancient forms that are associated with one of the first living forms on earth. Particularly, stromatolites are real bacteria communities where the autotrophic organism of the community are represented by cyanobacteria, which live along with heterotrophic bacteria. This clearly indicates that fossilized stromatolites points to bacteria (prokaryotes) as the first living things on earth (dated with not less than 3.5 billion year old)
Nowadays, stromatolites with cyanobacteria allows to reconstruct and understand fossilized forms. These current structures live in shallow marines ambients (e.g. Australia) but also in continental salt flats (e.g. Argentina) where few others bacteria can survive to these extreme conditions (high light exposure and salt concentration).
Answer: C.
Explanation
There are higher C-H bonds in lipids than in Carbohydrates.
These C-H bonds stored higher chemical potential energy effectively of thr amount (413 kj/mol.)
Carbohydrates has high C-O glycosidic bonds or linkages of ( 358 kj/mol) which stores low amount of energy compare to C-H bonds.
Futher more higher ATPS are produced during ELECTRON TRANSPORT CHAIN REACTION per molecules of tryglycerides metabolize compare to molecules of glucose because the longer chains of lipids ensures that more C-H bonds broken down ,ans therefore more oxidation to supply protons for ATPS synthesis from.proton pumps.
Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest
