Percent error is calculated by the expression:
%error = |actual value - observed value| / actual value x 100
We calculate the error of the values as follows:
<span>a. 23.487 cm
% error = |</span><span>23.490 - 23.487| / 23.490 x 100 = 0.013%
</span><span>
b. 23.493 cm
</span>% error = |23.490 - 23.493| / 23.490 x 100 = 0.013%
<span>
c. 23.516 cm
</span>% error = |23.490 - 23.516| / 23.490 x 100 = 0.11%<span>
d. 23.501 cm
</span>% error = |23.490 - 23.501| / 23.490 x 100 = 0.05%<span>
e. 23.477 cm
</span>% error = |23.490 - 23.477| / 23.490 x 100 = 0.055%
Answer:
Answer is D.
Explanation:
Eukaryotic organisms are organisms that possess nucleus and membrane -bound organelles. They derived their name from the word eukaryote, which means true nucleus. They can be single-celled or multi-celled. Examples are fungi, some unicellular organisms, plants and animals.
Prokaryotic organisms are all other organisms that lack membrane -bound organelles and nucleus. Examples are viruses, bacteria and certain algae.
Answer:
A glucose molecule is smaller
Explanation:
An artificial membrane has pores of a specific size.
Molecules that are small enough can pass through the pores, but others may be too big.
Glucose (C₆H₁₂O₆) has a certain size, but a sucrose molecule (C₁₂H₂₂O₁₁) is bigger.
If the membrane pores are just the right size, a glucose molecule will be able to pass through, but a sucrose molecule won't.
Answer:
Pseudopods
Explanation:
Amoeba move by extending their cytoplasm to form pseudopods on the surface of mud or soil. The pseudopodia are formed by forward streaming of endoplasm forming a protuberance. The endoplasm then converts to ectoplasm which stiffens the pseudopodium. More cytoplasm flows into the pseudopodium with the result that the organism gains a new position.
