Lipids don't dissolve in water because of the different polarities. Water is polar and lipids are not polar which is why they don't dissolve. What this means is that they don't bond and don't share electrons and therefore don't mix.
<span>The correct answer to this question is C - an autotroph is an organism that has to produce it's own food rather than finding sources of food elsewhere, so an example of this might be a primary producer. Plants and certain types of bacteria are all autotrophic.</span>
Answer:
The star is traveling <em>towards</em> the earth.
Explanation:
Space experts arrange stars into groups as per their shading and the composition. This star arrangement framework goes this way: O, B, A, F, G, K, M in which O star is blue and is very hot and <em>M stars are red</em> and the coolest and most basic stars in the Universe.
From the color of the star we can infer that as the star is appearing red it is inferred that the star is an M star and it is traveling towards the earth.
Correct answer - potometer.
Why? - The potometer does not measure the rate of transpiration accurately because not all of the water that is taken by the plant is used for transpiration (water taken might be used for photosynthesis or by the cells to maintain turgidity). The potometer measures the rate of uptake of water.
