the third Choice is the answer i think.
-Archaebacteria, Eubacteria, Animalia, Protista, Fungi, Plantae
Both A and C would be out since mammals and species are not kingdoms
Now we would be left with both B and D after looking at both answer I choose B since Insectae is not a kingdom
Hope that helped
The element starts off as 100%. half of 100% is 50% and half of 50% is 25%. the element has emitted 2 times the half life which is 10,000 x 2 = 20,000
the fossil bone is 20,000 years old
The answer would be (d). The federal drug administration needs to handle this case, do to the product not having restrictions on selling their product strictly to residence of North Carolina.
<u>Answer:</u>
<em>Enzyme activity decrease at these temperatures.
</em>
<u>Explanation:</u>
Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions. In <em>light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH</em>. In dark reactions carbon is fixed using the <em>ATP and NADPH.
</em>
The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about <em>10°c - 20°c</em>. At low temperatures and high temperatures enzyme activity is less efficient.
<em>At a temperature above 38°c and below 0°c enzyme activity decreases.
</em>
