The Grand Canyon is made of sedimentary rock that contains fossils up to 1 billion years old. and the several upper layers of rock contain terrestrial, or land-based, fossils, such as dragonfly wing impressions and the footprints of scorpions, centipedes, and reptiles
Answer:
c and d
Explanation:
<u>A species of an organism with cell wall that lacks peptidoglycan is definitely not a bacterium because bacterial cell walls usually have peptidoglycan.</u>
One particular group of organisms whose cells have cell walls but lack peptidoglycan is Archaea.
<em>Archaea represents a group of prokaryotes that are able to survive in extreme conditions such as high temperature, pressure and salinity. As such, they could inhabit hydrothermal springs as well as alkaline hot springs.</em>
Hence, thermoacidophile <em>Sulfolobus acidocaldarius </em>is likely to be an Archaea and could inhabit both hydrothermal springs and alkaline hot springs.
The correct option is option c and d.
Answer:
As a new covalent connection develops between the two glucose molecules, one loses a <em>H group,</em> the other loses an<em> OH group</em>, and a <u>water molecule is freed</u>.
<h2>
Why does glucose form a polymer despite being a stable molecule?</h2>
The formation of glucose polymers (glycogen, starch, cellulose) requires the input of energy from uridine triphosphate (UTP). Any tiny molecules must be converted into bigger molecules, which is compatible with the second rule of thermodynamics. Building proteins from amino acids, nucleic acids from nucleotides, fatty acids and cholesterol from acetyl groups, and so on are examples. Energy is released when bigger molecules are broken down into smaller ones, which is compatible with the second rule of thermodynamics. Thus, glucose may be converted to CO2 and H2O, resulting in the production of ATP. While glucose is a tiny molecule and hence relatively "stable," it can exist at a potential energy level and may be used to build up (needs energy) or broken down (<em>produces</em> energy). All of these biochemical processes require the use of enzymes; otherwise, the activation energy of most reactions would require extremely long periods of time for random energy inputs to push the reactions in either direction, despite the fact that energy considerations favor spontaneous breakdown over synthesis.
Answer:
I think its c because they aren't radiating or splitting. It seems the most reasonable.
