It takes 4.08 nanoseconds to travel 4.00ft in vacuum
time = dist/speed
Find the time it takes turtle to cover 100ft
<span> = 100/20= 5 minutes

Find the time (t.) for the rabbit to cover 100ft
<span>t. = (50/40)</span><span> + 3 + (50/40)</span>
<span>t. = 1.25 + 3 + 1.25 </span>
<span>t. = 5.5 min
the turtle won the race by 0.5 minutes</span>
Answer:
B• The hydrophilic phosphate groups of the phospholipid molecules are attracted to the aqueous internal and external environments.
Explanation:
Hello, you did not put the model to which this question refers, but I can say that the letter B is the correct answer, due to the composition that the phospholipids present.
Phospholipids are a molecule formed by two tails of hydrophobic fatty acids, that is, they do not come into contact with water, and a type of "head" that is a hydrophilic phosphate group, that is, it allows contact with water.
When a molecule formed by phosphate groups is found in an aqueous medium, it is common for the hydrophobic tail to be attracted to the inner corner of the molecule, preventing contact with water, while the hydrophilic part faces the outer side of the molecule.
