Ocean trenches are deep sections of the ocean where an oceanic plate is usually sinking below a continental plate. How are they formed? They are formed in the subduction zone as the denser oceanic plate is subjected under the continental plate.

Answer:Ocean trenches are driven by tectonics and are most commonly found along the Pacific Ocean in a zone known as the ring of fire. They are usually formed at the boundaries of convergent plates, at a region where a continental plate submerges beneath an oceanic plate.

if the united states continues using petroleum in vast amounts, it will become even more dependent on foreign sources for this r
Snowcat [4.5K]

Since we've been using petroleum in vast amounts organizations such as OPEC have appeared which restricts the U.S which ensued our country into suing; if this lawsuit passes then we will possibly be taking more petroleum than ever before due to it's demand such as it's needed for machinery and vehicles and etc. Most petroleum are from middle eastern countries, so our dependency will run rampant which will make us adhere to any of their policies pertaining to this fossil fuel in the near future.

If acetyl-CoA is labeled with 14C at its methyl group, how many rounds of the cycle are required before 14CO2 is released?
Elis [28]

Answer:

14 CO₂ will be released in the second turn of the cycle

Explanation:

<u>Complete question goes like this</u>, "<em>The CO2 produced in one round of the citric acid cycle does not originate in the acetyl carbons that entered that round. If acetyl-CoA is labeled with 14C at the carbonyl carbon, how many rounds of the cycle are required before 14CO2 is released?</em>"

<u>The answer to this is</u>;

  • The labeled Acetyl of Acetyl-CoA becomes the terminal carbon (C4) of succinyl-CoA (which becomes succinate that is a symmetrical four carbon diprotic dicarboxylic acid from alpha-ketoglutarate).
  • Succinate converts into fumarate. Fumarate converts into malate, and malate converts into oxaloacetate. Because succinate is symmetrical, the oxaloacetate can have the label at C1 or C4.
  • When these condense with acetyl-CoA to begin the second round of the cycle, both of these carbons are discharged as CO2 during the isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase reactions (formation of alpha-ketoglutarate and succinyl-CoA respectively).

Hence, 14 CO₂ will be released in the second turn of the cycle.

In most cases, the two major climatic factors affecting the distribution of organisms in terrestrial ecosystems are __________.
sesenic [268]

Answer:

precipitation and temperature

Explanation:

Temperature and water are considered major abiotic factors that affect species distribution in terrestrial ecosystems. The temperature can affect the distribution of terrestrial organisms due to many species maintain a constant internal temperature, while other species maintain a body temperature range that may be very different from the environmental temperature, and therefore they will not be able to carry out their metabolic functions. Hibernation is an adaptation that allows some terrestrial animals to escape temperature fluctuations. Moreover, water is another limiting factor for life, since water is critical for cellular processes. The waxy cuticle is an adaptation that allows terrestrial plants to avoid excessive water loss through transpiration.
