Explain what happens as the heart grows bigger.
Answers
Initially, the heart may grow bigger as a compensatory mechanism to try to keep up with increased demands for blood and oxygen. For example, if a person engages in regular exercise, their heart may enlarge to accommodate the increased demand for blood and oxygen to the muscles.
However, if the heart continues to grow over time, it can become less efficient at pumping blood and may develop structural abnormalities that increase the risk of heart failure, arrhythmias, and other complications.
In some cases, cardiac hypertrophy may be reversible if the underlying cause is treated, such as by managing high blood pressure or heart disease. However, if left untreated, hypertrophy can lead to irreversible damage to the heart muscle and may require more aggressive interventions, such as medication, surgery, or other medical procedures to manage the condition.

Who knew that so many forces acted on an object? Some make contact, others do not. Choose the forces that do not make contact with the object. There is more than one answer.
Question 1 options:
push
pull
motion
gravity
friction
Answers
Answer:
Gravity and electrostatic force
Explanation:
Gravity is a non contact force because the earth also attracts objects above its surface (not touching the earth). However, the further an object is from the centre of the earth, the weaker the force and the smaller its weight
The forces that do not make contact with the object are Gravity and Friction.
Gravity is a force exerted due to the pull of the Earth towards its center. It does not require direct contact as it attracts objects due to mass.
Friction is a force that opposes the motion of a body. It acts on the surface of a body in contact, not necessarily the body itself.
Therefore, Gravity and Frictions are the only two forces that do not make contact with the object out of the options.

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.

4. The Himalayan Mountains tower as high as 8,854 m above sea level. The rate of plate motion is about 10 cm per year. Use the diagram to explain how the Himalayas formed. Predict how they might look in 10 million years.
Answers
Answer:
Forty million years ago, the continent of India, which was being carried northward by the Indo-Australian plate, collided with Asia forming the Himalayan mountain range (fold mountains). Since the initial encounter, the subcontinent of India has moved 2,000 kilometers farther north at a rate of 5 centimeters a year, sliding beneath Asia as it moves. In 10 million years India will plow into Tibet a further 180km. This is about the width of Nepal.

Why is it possible for railway tracks to buckle even though there are gaps in them?
Answers
These gaps which are of the order of a few millimeters, are provided to allow room for the rails to expand the rise in temperature due to the atmospheric temperature as well as the friction caused by running of train. All materials expand when heated and contract when cooled. The extent of expansion and contraction is quite low to be noticed by people or make much difference in most situations. However, since each section of the rail is very long, the expansion due to heating is significant, and unless space is provided for expansion of rails, the rails will bend to accommodate the increased length. This will make the railway unfit for running of trains.
Answer: the tracks will buckle under the force.
Explanation: Heat-related expansion places a lot of stress on the ties, ballasts, and rail anchors that keep the tracks fixed to the ground.

Which of the following is an example of an unbalanced force?
(A) A ball on the grass
(B) A book sitting on a table
(C) A chair leaning on the wall
(D) A stroller being pushed
Answers
Answer:
d
Explanation:
because the motion is changing as it slows down mark brainliest to help me out :)
The example of an unbalanced force is a stroller being pushed. The correct option is D.
What is unbalanced force?An object is said to be acted upon by an unbalanced force only when an individual force is not balanced by a force of equal magnitude and direction.
Unbalanced forces are caused by a forward force or thrust and a frictional force opposing each other.
Friction is an opposing force to motion. It occurs whenever two surfaces rub against each other, such as when you rub your hands together or apply the brakes on a bike or car.
Forces that are balanced are those that are opposite in direction and equal in size.
Equilibrium is defined as the presence of balanced forces. There is no change in direction when forces are balanced.
As here pushing a stroller is not balancing the force as the force applied is more than the opposing one.
Thus, the correct option is D.
