Answer:

Gold are formed in the

Part of the Gold exhibition. Gold may occur as deposits called lodes, or veins, in fractured rock. It may also be dispersed within Earth's crust. Most lode deposits form when heated fluids circulate through gold-bearing rocks, picking up gold and concentrating it in new locations in the crust.

Explanation:

Copper formed in the

Most nonrecycled supplies come from porphyry copper deposits (PCDs), which form when hot, metal-bearing fluids percolate up through Earth's crust. ... These fluids bubble up through the crust and collect in pores in the rock, where they sit, waiting for the final step that will allow them to form copper minerals.Jun 7, 2015

Which two factors have likely influenced global temperatures the most?
Alex787 [66]

Answer:

B: volcanic activity

D: fossil fuel consumption

Explanation:

Fossil fuel consumption and volcanic activity are the two factors that has a great influenced on the global temperatures. Fossil fuel consumption is a human activity and volcanic activity both releases carbondioxide gas while burning. This carbondioxide gas is a greenhouse gas which block the reflected solar radiation and leads to increase in the surface temperature of the earth.

Which of these is not part of insect immunity? A. enzyme activation of pathogen-killing chemicals B. activation of natural kille
Firlakuza [10]

Insect immunity doesn't include the property of an enzyme activation of pathogen-killing chemicals.

What is enzyme activation of pathogen?

Due to various trehalose's importance in pathogenic organisms, there has lately been a surge of interest in trehalose metabolism for therapeutic applications.

  • TPP (trehalose-6-phosphate phosphatase) is an important enzyme in the most important biosynthetic pathway (OtsAB).
  • The enzyme properties of recombinant TPPs from five key nematode and bacterial pathogens, including three new members of this protein family, are compared here.
  • The kinetics of trehalose-6-phosphate hydrolysis demonstrate that all five enzymes exhibit burst-like kinetic behaviour, defined by a drop in enzymatic rate beyond the pre-steady state.
  • Multiple global conformational changes in members of this enzyme family during substrate processing can explain the observed super-stoichiometric burst amplitudes.

Hence, the correct answer is option A
