_______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.

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.
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
Answer:
due to gravity.

Which is an example of convection currents?
marshmallows toasting over a campfire
a pot being heated by an electric burner
feet getting hot when stepping across sand
a radiator emitting warm air and drawing in cool air
Answer:
D
Explanation:
took the quiz!!! I picked B and got it wrong!
An example of convection currents is a radiator emitting warm air and drawing in cool air.
What is Convection?This is a method of heat transfer which is characterized by movement of a heated fluid such as air or water.
A radiator emitting warm air and drawing in cool air involves a fluid which is why option D was chosen as the most appropriate choice.

A tennis ball moves 16 meters northward, then 22 meters southward, then 12 meters northward, and finally 32 meters southward.
Determine the magnitude of the distance the object traveled
Answer:
26 m southwards.
Explanation:
From a North, East, South, West coordinate plane, moving northwards implies positive distance. While moving southwards implies negative distance.
Thus;
It moves 16 meters northward; d = 16 m
It now moves 22 meters southward; d = -22 m
It moves 12 meters northward; d = 12 m
It moves 32 meters southward; d = -32 m
Thus, total magnitude = 16 - 22 + 12 - 32 = -26 m
Thus, the object travels 26 m southwards.
What new details are you able to see on the slide when the magnification is increased to 10x that you could not see at 4x
Answer: A more detailed information like the nucleus of cells on the slide is seen as the magnification Increases.
Explanation:
The microscope is an instrument used in a laboratory to view magnified image of an object ( cells on a slide). There are two types:
--> Simple microscope and
--> Compound microscope.
Simple microscope is used to view an object using JUST ONE convex lens, and the image formed is usually erect and magnified.
Compound microscope has a higher magnification compared to a simple microscope. It is produced by using TWO CONVERGING LENS of short focal length. Here, the two lenses used are classified according to their positions. The lens near the object is called the objective lens while the one nearer to the eye is called the eyepiece lens.
The objective lens of the compound lens used in the laboratory has ×4, ×10, ×40, ×100 magnifications. As the magnification of the objective lens is increased from ×4 to ×10 a more detailed information of the image is seen as the diameter of field of view decreases. For example the constituents of a cell like the nucleus can be viewed using a higher magnification.
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.
