Answer:
is used by commercial airplanes
Explanation:
The stratosphere is used by most commercial airplanes. This is because this layer of earth is stratified and more stable.
- The lowest level of the atmosphere is the troposphere.
- This layer is where all the bulk of the atmospheric gases are domiciled.
- Weather conditions occur here.
- This layer is not safe for flight due to its turbulent nature.
- The ionosphere is responsible for the transmission of radio signals around the earth.
- The earth's weather occurs in the region of the troposphere.
Answer:
true
Explanation:
without your DNA, protein synthesis couldn't happen, think of DNA as the blue prints for protein synthesis.
Answer:
Mg is able to give off two of its electrons to other molecule, not four. ATP, in this case is the aceptor of those electrons
Two correct answers are:
1) Hexokinase cannot bind active ATP when it is not complexed with Mg2+
2) Mg2+ makes the terminal phosphorus atom of ATP more accessible to nucleophilic attack by a glucose-OH group
Explanation:
As Mg occurs naturally as ion Mg++, it is able to give off only two of its electrons to other molecule, then it is possible for ATP to receive two electrons of Mg, forming MgATP2-
The hexokinase reaction, here cited, corresponds to the glucose phosphorylation of its sixth carbon to produce glucose-6-P, which is a glycolysis intermediate. In this way glucose is activated (ATP is initially invested to energize glucose). Later on, Glyceraldehide-3-P is produced, and finally converted to pyruvate, NADH2 and ATP
Answer:
Air is forced to rise over mountains, air cools and condensation occurs, rain falls over the mountains, dry air sinks down the other side of the mountain. Some deserts form in areas that lie at great distances from the sea. The air here is much drier than on the coast.
