All of the liquid molecules in cell membranes amphipathic (or amphiphilic) -that is, they have a hydrophilic ("water loving") or polar end and a hydrophobic ("water fearing") or nonpolar end. The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails.
Hope that Helps :)

Answer:
- time: 1.122 seconds
- range: 10.693 m
- maximum height: 1.543 m
Explanation:
<u>Given</u>:
runner is launched at 30° angle to horizontal at 11 m/s
acceleration due to gravity is g = -9.8 m/s²
<u>Find</u>:
runner's hang time
runner's distance to the landing point
runner's maximum height
<u>Solution</u>:
The (horizontal, vertical) speed components will be ...
(11 m/s)(cos(30°), sin(30°)) = (5.5√3 m/s, 5.5 m/s)
The time of flight can be found from the height formula:
h(t) = 1/2gt² +vt . . . . . . where v is the vertical speed at launch
The time we're concerned with is the time when h(t)=0 and t>0.
0 = -4.9t^2 +5.5√3t = t(-4.9t +5.5√3)
The second factor is zero when ...
t = (5.5√3)/4.9 ≈ 1.122 . . . seconds hang time
__
The distance to the landing point will be the product of horizontal speed and hang time:
d = (5.5 m/s)(5.5√3/4.9 s) ≈ 10.693 m . . . . distance to landing
__
The maximum height can be found from the formula (based on conversion of kinetic energy to potential energy) ...
h = v²/|2g| = (5.5 m/s)²/(2(9.8 m/s²)) ≈ 1.543 m . . . . maximum height
You answer to this question will be: A) Camouflage, Mimicry, and Stingers*
Answer:
The correct answer is - speciation is sympatric.
Explanation:
Sympatric speciation is a process of speciation that takes place when there is reproductive isolation between two populations of a species without any geographical separation.
This speciation takes place in the population with come ancestors as given in the question both pods of dolphins lose their ability to interbreed due to the sympatric speciation without any geographical separation.
Thus, the correct answer is - speciation is sympatric.
Answer:
Mitosis provides two diploids (2n) somatic cells that are genetically indistinguishable from each other and the primary parent cell, whereas meiosis creates four haploids (n) gametes that are genetically individual from each other and the original parent (germ) cell.
