<em>The measurement 100.5 mL has 4 significant figures.</em>
<u>Explanation:</u>
Significant figures are defined as the digits that provides information in order to maintain accuracy and precision of a measurement. <em>Any nonzero number, trailing zeros with a decimal point and zeros between two numbers are recognizes as significant digits. </em>
Whereas, the figures which do not contribute to sustain the accuracy and precision of the measurement are insignificant figures.
<em>The leading zeros in any digit and the trailing zeros without decimal are considered as insignificant figures. </em>
<em>As in 100.5 1, two zeros and 5 after a decimal is significant figure which are 4 in total.</em>
Plants perform photosynthesis and cellular respiration.
Explanation:
Cellular respiration is the conversion of glucose into ATP and energy yielding molecules such as NADH and FADH2 along with water and oxygen and carbon dioxide as by-products.
Cellular respiration is a process that occurs both in autotrophs and heterotrophs.
Only the final stage of cellular respiration i.e. oxidative phosphorylation or electron transport chain requires oxygen as the final electron acceptor.
Heterotrophic cells don't take in carbondioxide, they utilize glucose obtained through food.
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. (Draw a plant and this is tghe one you underline)
A heterotroph is an organism that eats other plants or animals for energy and nutrients. (You can draw a dog, cat, frog or a person)
