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.

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.

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,

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.

Letter X represents the Mitochondria which marks the location where carbon dioxide is produced during respiration. So, the correct option is B.

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.

So, the correct option is B.

Answer:

Simply put your hand out and block them and put them back in the corner in a sit position. make sure that you let your dog know that not moving is what gets them. The reward gradually increase the distance and time as we did in the corner until they can stay for 10 seconds at 10 feet away.

Also, with a leash, when teaching your dog to stay, say "stay" and pull the leash back to when the dog is sitting. This gives the dog an understanding of what to do and how to do it. Repeat this a few times. Then the dog will learn to sit and stay before the leash stops. Then they will have learned the "Stay" command.

Hope this Helps!

Answer:

Positive reinforcement is one of the best ways to train a dog. This may be treats, such as a biscuit, or affection, like a belly rub. There's also giving them a new toy, or taking them on a walk even. Most trainers have these tools called clickers. They get a dog's attention and keep it, refocusing them if they wander off mentally.

Not all trainers train their dogs to stay the same way. More popular ones may give the command "Sit!", which sometimes isn't very effective. I personally trained my dogs with a type of sign language. One finger up for "sit", and two for "stay". Full hand is "down" or "wait". As I said, many different ways of training.

If a dog does not respond to positive reinforcement, there is negative reinforcement, but it is seriously frowned upon. This could be a water bottle or receiving no treats. Some people take this too far, however.

The best way to train a dog to stay is to be patient with them, use positive reinforcement, and to understand. They're a dog, they're bound to be distracted, just like a child. To refocus them, snap your fingers or whistle, and if need be, call their name. Don't expect them to learn it all in one day: all dogs have different personalities and learning capabilities. One dog may pick it up quick, while it may take another month to learn, just like humans.

You also have to take into consideration age and history of the dog. These are two very important factors in training, as if a dog is used to being spoiled rotten, positive reinforcement most likely won't help. If the dog is a young puppy, they're going to want to learn and explore instead.

C. Like other populations, the human population is affected by a variety of factors in the environment

Note: The options are found in the attachment below

Explanation:

Factors that affect population in the natural world include; availability of food, water, shelter, space, competition for resources, predation, as well as disease.

These factors also affect human population resulting in an increase, decrease or stability in population.

Regarding decrease in population, factors like competition for scarce resources has resulted in wars which greatly reduced human population. Also disease outbreaks, droughts, famines, etc have resulted in decrease in population.

Availability of food, water, shelter and space on the other hand makes for an increase in population by increasing the birth rate, reducing competition and bringing stability.

In some other instances, overtime, there is a balance between birth and death rate, so human population will remain relatively unchanged at these times.

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.

Molecule 3

Explanation:

DNA contains Deoxyribose, Phosphate, and 4 bases: Adenine(A), Thymine(T), Guanine(G), and Cytosine(C)

Molecule three contains Deoxyribose, Phosphate, and Guanine, while the others do not.

RNA contains ribose, which is why Molecule 2 is out of the question.

DNA does not contain glucose, henceforth marking Molecule 1 incorrect.

Molecule 4 may seem correct, but recall that DNA contains Deoxyribose, Phosphate, and a base, in this case Guanine(G). This answer contains no Deoxyribose.
