Answer:
The electrochemical gradient of the ion that is being transported.
Explanation:
Facilitated diffusion through protein is defined as a form of facilitated transport whereby passive movement of ions along concentration gradients are guided by the presence of other ions.
Thus, the electrochemical gradient of the ion being transported is what facilitates it
A 15.0 kg bowling ball rolling at 3 m/s is stopped by a constant force of 11.2 newtons. Calculate the time the force must act on the bowling ball to stop it.
Answer:
4.01 seconds
Explanation:
Given that:
Mass of ball = 15kg
Initial velocity, u = 3m/s
Final velocity, v = 0
Force, F= 11.2 N
Change in velocity, dv = 3 - 0 = 3
Time force must act on the ball before stopping it:
Using the relation :
F = ma
a = (v - u) / t
Ft = m(v - u)
11.2 * t = 15 * 3
11.2t = 45
11.2t = 45
t = -+¯ 45 / 11.2
t = 4.01
t = 4 seconds.

_______1. Allows ingestion and breaks down food so that nutrients can be absorbed.
_______2. Provides mechanical support; stores minerals and produces red blood cells.
_______3. Protects the body's internal environment and stores fat.
_______4. Enables the transport of nutrients, glasses and wastes to and from cells.
_______5. Secretes hormones into the bloodstream for regulation of cellular activities.
The correct answers for the given paragraph are as follow:
Digestive Enzymes allows ingestion and breaks down food.Skeletal system provides mechanical support and also stores minerals.Integumentary system protects the body's internal environment and stores fat.Cardiovascular system enables the transport of nutrients, glasses and wastes to and from cells.Endocrine glands secretes hormones into the bloodstream for regulation of cellular activities.1.
The digestive enzymes are the proteins that tends to break down the larger molecules like fats, proteins and carbs into smaller molecules.
Thus, the correct answer is Digestive Enzyme.
2.
The skeletal system is the framework of body, consisting of bones and various connective tissues. It provides the mechanical support and produces red blood cells.
Thus, the correct answer is skeletal system.
3. The organ system that protects the body's internal environment and stores the fat is known as Integumentary system.
Thus, the correct answer is integumentary system.
4.
The cardiovascular system enables the transport of nutrients, glasses and wastes to and from cells. Also, it is used for the transportation of nutrients and oxygen-rich blood to all parts of the body and to carry deoxygenated blood back to the lungs.
Thus, the correct answer is cardiovascular system.
5.
Endocrine glands are responsible for the secretion of hormones into the bloodstream to regulate the cellular activities.
Thus, the correct answer is Endocrine glands.

Does the KE of a car change more when it accelerates from 22 km/h to 32 km/h or when it accelerates from 32 km/h to 42 km/h
Answer:
The change in kinetic energy (KE) of the car is more in the second case.
Explanation:
Let the mass of the car = m
initial velocity of the first case, u = 22 km/h = 6.11 m/s
final velocity of the first case, v = 32 km/h = 8.89 m/s
change in kinetic energy (K.E) = ¹/₂m(v² - u²)
ΔK.E = ¹/₂m(8.89² - 6.11²)
= 20.85m J
initial velocity of the second case, u = 32 km/h = 8.89 m/s
final velocity of the second case, v = 42 km/h = 11.67 m/s
change in kinetic energy (K.E) = ¹/₂m(v² - u²)
ΔK.E = ¹/₂m(11.67² - 8.89²)
= 28.58m J
The change in kinetic energy (KE) of the car is more in the second case.
without calculation explain why the vertical component of velocity v h changes from 3.5 m/s at A to 0 m/s at B
