Prokaryotes- lack a cell nucleus, unicellular, in the bacteria and archaea domain, lack mitochondria and chloroplast, microscopic
eukaryotes- contains a cell nucleus, multicellular, only in the eukarya domain, contains mitochondria and chloroplast, not microscopic
A general ballpark how one can predict the way how evolution will work in the future would be by thinking about the requirement of a certain area or environment and which changes would be necessary and relevant for any organism to thrive with its new changes.
This could help people speeden up this process by enabling organisms to develop such traits faster, as well as ourselves.
Answer:
Diffusion rate is 1.96 ×
/s
Explanation:
Diffusion is the process in which the molecules of a substance propagates from a region of higher concentration to region of lower concentration through a semi-permeable membrane.
diffusion rate = 
Given that; diameter = 15 mm, time = 15 minutes.
The dye spread in a circular form, so that;
area = 

r =
=
= 7.5 mm = 0.75 cm
area =
×
= 1.7679 
time = 15 minutes = 15 × 60 = 900 seconds
So that;
diffusion rate = 
= 0.0019643
/s
Diffusion rate is 1.96 ×
/s
Answer:
<em>b. False</em>
<em></em>
Explanation:
Increasing the frequency of muscle stimulation causes wave summation to occur, which causes an overlap of muscle twitch. When this muscle summation happens, the force generated in the muscle increases. This means that stimulating the muscle every 0.5 seconds will generate less muscle contraction force than when stimulated every 0.05 seconds
