The coleoptiles which tips were removed will be short and straight while coleoptiles which were cut with the tips separated by mica will be short and straight. Ceoptiles which were cut tips and separated by agar they will be tall and straight.
The set of coleoptiles which will be left in the darkness for 24 hours will be tall and bent. While the set which is in the direction of light for 24 hours will be tall and bent.
Observation is that coleoptile will grow straight if the chemical was evenly distributed and curved away from block side as if growing towards the light because dark side has the higher concentration of auxin.

Answer: Hydrophobic
Explanation:
Think about how water reacts with oil. When you mix the two the oil would stay in little drops within the water so they are not mixing. The tails of the membrane prevent water from leaking out by sticking together and not letting water through. Just to solidify this Phobia= fear, lipids are water "fearing".
Answer:
1.292 M
Explanation:
<em>In order to calculate the concentration of H2SO4, we need to get the balanced equation of reaction first;</em>
Using the formula:
CaVa/CbVb = na/nb
where Ca = concentration of acid, Va = volume of acid, Cb = concentration of base, Vb = volume of base, na = number of moles of acid, and nb = number of moles of base.
In this case, Ca =?, Va = 10.00 ml, Cb = 0.777, Vb = 33.25 ml, na = 1, nb = 2
Ca = CbVbna/Vanb = 0.777 x 33.25 x 1/10 x 2
Ca = 1.292 M
Hence, the concentration of H2SO4 is 1.292 M
