C- the biosphere use the géosphère as land/ home.
D-The géosphère depends on the hydrosphere for water. Without the water, the géosphère would eventually turn dry and nothing will be able to grow
E- The animals in the hydrosphere need air to survive. The gills on sea animals are used to filter out the water from the oxygen and use the oxygen to breathe. As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that's dissolved in the water.

Place the parts of the human circulatory system in order from highest to lowest degree of internal organization.
→ → →
Answers
Answer: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows: Heart, Blood Vessels, Arteries, Veins, and Capillaries.
Explanation: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows:
Heart: The heart is a vital organ responsible for pumping oxygenated blood to the body and deoxygenated blood to the lungs. It consists of chambers (atria and ventricles) and valves that regulate blood flow.
Blood Vessels: Blood vessels form a network of tubes that transport blood throughout the body. They can be classified into three types: arteries, veins, and capillaries.
Arteries: Arteries are thick-walled blood vessels that carry oxygenated blood away from the heart to various parts of the body.
Veins: Veins are blood vessels that transport deoxygenated blood from the body back to the heart. They have thinner walls compared to arteries and contain valves to prevent backflow.
Capillaries: Capillaries are tiny, thin-walled blood vessels that connect arteries and veins. They facilitate the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.
Please note that this arrangement is based on the internal organization of the circulatory system, with consideration given to the hierarchical structure and function of each component.

Justin and Oscar each hit a baseball with a bat. The baseballs have the same mass, but the ball Justin hits has a greater acceleration. What might be the reason for the greater acceleration of Justin's baseball?
Answers
The acceleration is different in both cases because, the force applied is different. Acceleration is force divided by mass of the object. Thus, Justin had greater force than Oscar.
What is force ?Force is an external agent acting on body to change its motion or deform it. There are various kinds of forces such as frictional force, gravitational force, nuclear force etc.
According to Newton's second law of motion, the force acting on an object is the product of its mass and acceleration.
Thus, F = ma
Hence, as the force increases the body is accelerated more.
With the same mass for the two balls, the force used to hit it was different and thus, the acceleration differs in both cases. Therefore, Justin has the greater force.

Which of the following is the best description of the term resultant
displacement?
A. The scalar that joins all the points along the path.
B. The average of all the displacement vectors.
C. The total distance traveled.
O D. The shortest distance from the beginning point to the end point.
Answers
Answer:
D
Explanation:
Displacement refers to the shortest, or straight-line path from one point to another. It is a vector, thus A is incorrect. It is not the average, but rather the sum of all displacement vectors, so B is incorrect. It is not the distance traveled, as some paths have longer distances than others, while leading to the same destination, hence same displacement. (i.e. running around in circles yields positive distance traveled but zero displacement.)
Answer:
Explanation: D
Displacement is a vector. It has direction and it has magnitude. But we are asked for the resultant displacement. You have to use pythagorean theorem. This makes our answer always positive. That essentially means distance, since you did just do the distance formula.
A is wrong because that tells you perimeter
B is wrong because that tells you the midpoint
C is wrong because displacement and distance are two different things. We dont want the distance of the two vectors
D is correct, this perfectly explains the distance formula
What would happen to the digestion process if enzymes were not present
Answers
Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.
Explanation:
I hope this helps
Without enzymes, the body would not be able to break down complex carbohydrates, proteins, and fats into their component molecules. This means that these nutrients would not be absorbed by the body and would be excreted as waste.
Additionally, the lack of enzymes would make it difficult for the body to digest and absorb vitamins and minerals. This could lead to malnutrition and other health problems over time.
Overall, the absence of enzymes from the digestive process would severely impair the body's ability to extract nutrients from food and could have negative consequences for overall health and well-being.

Compared to wave A, wave B has a _____.
shorter wavelength and lower frequency
longer wavelength and greater frequency
longer wavelength and lower frequency
shorter wavelength and greater frequency
Answers
Compared to wave A, wave B has a longer wavelength and lower frequency
Wavelength: It is the distance between two consecutive crusts or troughs.
Frequency: It is the number of waves that pass a given point in one unit of time
Wavelength and frequency are inversely proportional, i.e. a wave with a shorter wavelength will have a higher frequency while a wave with a longer wavelength will have a lower frequency.
From the image, we can see that in wave B the distance between two consecutive crests or troughs is longer than that of wave A. This means that it has a longer wavelength and since wavelength and frequency are inversely proportional, it means that wave B has a lower frequency.

Allie took archery lessons and became proficient after several months. She placed the arrow into the bowstring, pulled it back, and released the arrow. She did not hit the bull's-eye, so she decided to shoot another arrow. Describe the kinds of energy she demonstrated in each step of the process, and how they changed.
Answers
At this stage, Allie primarily exhibits potential energy. The arrow possesses potential energy due to its position and the forces acting upon it. The potential energy is stored in the bowstring, which is stretched when the arrow is placed.
Pulling back the bowstring:
As Allie pulls back the bowstring, she exerts force, converting her muscular energy into elastic potential energy. The energy is stored in the flexed bowstring and the limbs of the bow. The further she pulls back, the more potential energy is accumulated in the bow.
Releasing the arrow:
When Allie releases the bowstring, the potential energy stored in the bowstring and limbs is rapidly transformed into kinetic energy. The potential energy is converted into the energy of motion as the bowstring snaps forward, propelling the arrow forward.
Arrow in flight:
As the arrow moves through the air, it possesses kinetic energy. The energy of motion is determined by the arrow's mass and velocity. The arrow's kinetic energy gradually decreases as it encounters air resistance and gravity.
During these steps, the energy transformations occur as follows:
Allie converts her muscular energy into potential energy when pulling back the bowstring.
The potential energy stored in the bowstring and bow limbs is transformed into kinetic energy when the arrow is released.
The arrow then travels through the air, converting its kinetic energy into other forms, such as heat due to air resistance and gravitational potential energy as it rises and falls.
It is important to note that there may be other forms of energy involved, such as thermal energy from the friction between the arrow and the bow or the surrounding air.
In each step of the archery process, Allie demonstrates different forms of energy.
Throughout the process, the kinds of energy involved change. Initially, Allie deals with potential energy in the arrow and the bowstring. Then, she converts her muscular energy into elastic potential energy when pulling back the bowstring. Upon release, the elastic potential energy transforms into kinetic energy in the arrow. Finally, during flight, the arrow primarily exhibits kinetic energy.
While placing the arrow into the bowstring, Allie is mainly dealing with potential energy. The arrow possesses potential energy due to its position relative to the ground. When Allie is Pulling back the bowstring, she exerts force, converting her muscular energy into elastic potential energy. The potential energy in the stretched bowstring increases as she pulls it farther back.
Allie releases the arrow, hence the stored elastic potential energy in the bowstring is rapidly converted into kinetic energy. The arrow gains kinetic energy, which is the energy associated with its motion.
To better understand the kinds of energy demonstrated in each step of the process, and how they changed:
