Plants are producers. The give energy to the herbivores. The gain energy from the sun.
Answer:
Mitochondria and the chloroplast
Explanation:
Electron transport refers to the transfer of of electrons from electron donors to electron acceptors via a reduction-oxidation reaction.
In the mitochondria the process is called Oxidative phosphorylation whereas in the Chloroplast it is called Photo-phosphorylation since it utilizes light.
Chemiosmotic mechanisms allow the movement of ions across a semi-permeable membrane down their electrochemical gradient.
In both mitochondria and chloroplast,have these mechanisms for the production of ATP .
Answer:
The results are not able to be reproduced.
Explanation:
Generally, if an experiment is done and the results/similar results can not be reproduced then it can be considered invalid.
Answer:
At 0 years, an event took place which is known as metamorphosis of igneous rock i.e., formation of igneous rocks from melted magma.
Strontium-90 is a radioactive element which undergoes beta decay to form yttrium-90. It has a half life of approximately 28 years and decay energy of 0.546 MeV. This radioactivity is used by geologist to estimate the age of the rock, fossils, meteorites etc. Other radioactive elements used by the geologists are carbon-40, potassium-40 etc.
Radiometric clock is set when the rock was formed in the past i.e., the moment when an ingenious rock was solidified from molten magma.
