A student observes the model and claims that the total mass of the reaction is conserved. Is the student's claim correct? Why or why not? A No, because the arrangement of atoms is different in the reactants and products. B Yes, because the reactants and products are made of atoms of the same elements. C Yes, because the number of atoms of each element is the same on both sides of the equation. D No, because the total number of atoms in products is greater than the total number of atoms in reactants.
C. Yes, because the number of atoms of each element is the same on both sides of the equation.
Due to the law of conservation of mass, any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

1) A vehicle is traveling at 150 km/h after 3 hours it is traveling 240 km/h.
Was the vehicle accelerating or decelerating and at what rate?
(And this is for science not biology)
Answer:
Accelerating (30km/hr²).
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]t is time measured in seconds.Given the following data;
Initial velocity, u = 150km/h
Final velocity, v = 240km/h
Time, t = 3 hours
Substituting into the equation, we have;
[tex]a = \frac{240 - 150}{3}[/tex]
[tex]a = \frac{90}{3}[/tex]
Acceleration, a = 30km/hr²
Therefore, the vehicle is accelerating at the rate of 30km/hr² because its final velocity is greater than its initial velocity.
For deceleration, the final velocity of an object such as a vehicle would be lesser than the initial velocity.

1.) What gives water all its properties? 2.) What type of bond joins H2O to another H2O and forms cohesion? 3.) What property of water prevents rapid temperature change inside the body of organism? 4.) Which property of water allows water to attach to roots of plants for capillary action? 5.) Water is found in many compounds such as blood, saliva, sweat because of which property of water? 6.)Which property of water causes water to form drops? 7.)Which property of water helps maintain extreme temperature changes in an area? 8.) What happens to hydrogen bonds when water turns to ice? 9.) Why doesn't water break down fat? 10.)Which property of water causes surface tension? Cohesion, Adhesion, High heat capacity, high heat vaporization and polarity
Answer:
1. polarity
2. hydrogen bonding
3. High heat capacity
4. Adhesion
5. polarity
6. surface tension
7. high heat vaporization
8. hydrogen bonds form a rigid and stable network
9. Water is a polar substance and fat is a nonpolar substance.
10. Cohesion
Explanation:
Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.
The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.
High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.
When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does not interact with fat because like dissolves like.
In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.

If all chloroplasts were removed from all living things, which substances
would no longer be produced?
Answer: Hope this helps!
Explanation:
In the process of photosynthesis sunlight is absorbed by the chloroplasts to make sugar. Therefore, if chloroplast is taken out of the cell, the green plant will not be able to carry out the process of photosynthesis which means the plant will die. Without chloroplasts, plants would not be able to get their energy from the sun and would cease to survive, leaving us without food.

Explanation:
Producers, consumers, and decomposers all participate in the carbon cycle during
their lifetimes. Identify and explain the process through which producers remove
carbon from the atmosphere. Identify and explain how producers, consumers, and
decomposers return carbon to the atmosphere.
Answer:
Carbon Cycle
Everything You'll Have Covered
What role do producers, consumers, and decomposers play in the carbon cycle?
~ Producers synthesize their food through photosynthesis using energy from sunlight and carbon dioxide from the air. Their respiration returns carbon dioxide to the atmosphere. Consumers use the food produced by producers for energy. Their respiration also returns carbon dioxide to the atmosphere. Decomposers break down plant and animal waste products. They also break down dead plants and animals. The decomposing process releases carbon dioxide gas into the atmosphere.
How do fossil fuels and volcanic activities contribute to the carbon cycle?
~ When fossil fuels are burned, carbon dioxide is released into the atmosphere in the form of gas. When volcanoes erupt, carbon dioxide that was in the magma passes into the atmosphere as carbon dioxide gas.
How is carbon returned to the Earth and sea in the carbon cycle?
~ Carbon is returned to the Earth and sea in the form of precipitation after carbon dioxide mixes with rain and snow. Erosion is another way that carbon is returned to the sea. When shellfish die, the carbon that was in their shells collects at the bottom of the ocean and eventually forms sedimentary rocks.
Give one example of a human activity�that could disrupt the�carbon�cycle�as well as the consequences of this disruption.
~ Burning fossil fuels can disrupt the carbon cycle, since they increase carbon dioxide in the air, which can lead to environmental problems such as acid rain.
Photosynthesis is the process by which plants produce their food in the presence of sunlight that is solar energy with the use of carbon dioxide and water. The breakdown is the mechanism by which plants give their carbon dioxide back.
What is end product of photosynthesis ?The end products of photosynthesis are glucose and oxygen that is given back to the atmosphere.
In plants, photosynthesis is the process by which plants prepare their food in the presence of sunlight and glucose is made thus this is the way by which plants are preparing their food and in the case of plants glucose is stored in the form of starch.
With the reactions going on when the cellular respiration reactions are going on at that time the reactions produce enough of carbon dioxide which is given back to the atmosphere thus this dependency helps to interpret the mutual relationship.

Letter X represents the Mitochondria which marks the location where carbon dioxide is produced during respiration. So, the correct option is B.
What is Mitochondria?A mitochondrion is defined as an organelle which is found in the cells of most eukaryotes, such as animals, plants, and fungi that have a double membrane structure. It uses aerobic respiration to generate adenosine triphosphate, which is used throughout the cell as a source of chemical energy.
The main role of mitochondria is oxidative phosphorylation which utilizes the energy released during the oxidation of the food we eat to generate ATP which is used as the primary energy source for most biochemical and physiological processes such as growth, movement and homeostasis.
