Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration.

pls make it simple and not write a whole paragraph

Answers

Answer:

Explanation:

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.

Answer:

the law of conservation of matter

Explanation:

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.

The Law of Conservation of Matter states that the reactants must equal the products, which is demonstrated through the equation that demonstrates cellular respiration.

C6H12O6 + 6O2 -> 6CO2 + 6H20

This shows that hydrogen has been conserved throughout the entire process (H representing Hydrogen) as the product has the same amount of hydrogen as the reactants.

Glue the nucleus to the center of the cardboard. 3. Determine how many rings you need for the electrons. Starting from the innermost ring, you can have up to two electrons in the first ring, up to eight in the second ring, up to 18 in the third ring and up to 32 in the fourth ring. 4. Glue the string around the nucleus to make the energy level rings. 5. Apply a few drops of glue to each ring. 6. Glue the electrons on the rings, spacing them evenly. Make sure you don’t exceed each rings maximum number of electrons. If you are trying to draw one then you could easily find one online

NaCl
C2H6
MgO
Ag6
N2O4
F2
Fe5
CO2

Answers

Answer:

The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.

relative charge = -1

Relative mass = 1.1836

It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.

He constructed the glass tube and create vacuum in it. He applied electric current between electrodes. He noticed that a ray of particles coming from cathode to wards positively charged anode. This ray was cathode ray.

Properties of cathode ray:

The ray is travel in straight line.

The cathode ray is independent of composition of cathode.

When electric field is applied cathode ray is deflected towards the positively charged plate.

Hence it was consist of negatively charged particles.

While neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.

Relative mass of proton= 1

Relative mass of neutron = 1

Relative mass of proton = +1

Relative charge of neutron = 0

The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The umber of protons and electrons are always equal to make the atom electrically neutral.

Answers

Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .

Explanation:

Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .

Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.

A praying mantis eats a bee.


Tell which type of relationship it is: mutualism, predation, parasitism, competition, or commensalism. Give details on why.

Try for 2 sentences:

I think a praying mantis eating a bee is an example of....

I think this because...

Answers

Answer:

I think a praying mantis eating a bee is an example of predation. I think this because the praying mantis stealthily hunts its preys, like the bee, in order to kill eat for food.

Explanation:

"Predation" refers to the killing of another living organism in order to prolong the life of the "predator" (hunter) and to end the reproductive life of the "prey" (the one being consumed). The praying mantis is popularly known for being a deadly predator because it feeds on several insects (as its prey), including the bees. They are said to also feed on wasps, moths, mice, frogs, rodents and even snakes.

It kills the bees in order to consume them so it can prolong its reproductive life. It then stops the reproductive life of the bees. Clearly, the type of relationship here is "predation."

I think a praying mantis eating a bee is an example of predation.

I think this is because the praying mantis which is a predator consume the prey which is the bee most times in a defensive manner.

Predation is a biological relationship in which a predator kills or consume it's prey.

It's occur majorly in canivorous animals that consume flesh or other animals.

The predators consume the prey as food and as a form of defensive means from been attacked by the prey.

In this relationship, energy is transfered from the prey which is the bee to the praying mantis.

Therefore, the relationship that occur between praying mantis and bee is predation.

To know the number of atoms of an element in any compound or molecule we have to multiply the coefficients that is written in front of the molecule to the number that is written on the foot of that element. So the correct option is option B

What is Balanced equation?

Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side

The number of carbon atoms on reactant side is 2 while on the product side it is 2

The number of Hydrogen atom on reactant side is 4 while on the product side it is also 4

The number of oxygen atom on reactant side is 1 while on the product side it is 6, so to balance oxygen we multiply O₂ by 3 so the balanced equation is

C₂H₄+3O₂\(\rightarrow\)2CO₂+2H₂O

Thus the balanced equation is C₂H₄+3O₂\(\rightarrow\)2CO₂+2H₂O. Option B is correct option

Blake is using a screw to hang on a picture in his room. Which of the these is the best description of a screw?

A. A screw allows you to use less force because a screw acts like a pulley.

B. A screw allows you to use less force because a screw acts like an inclined plane.

C. A screw allows you to do less work because a screw acts like a pulley.

D. A screw allows you to do less work because a screw acts like an inclined plane.

Answers

When using a screw to hang a picture, it is important to understand its function. The best description of a screw is option B - "A screw allows you to use less force because a screw acts like an inclined plane."

Screws are simple machines that have an inclined plane wrapped around a cylinder. This inclined plane is known as the thread. As the screw is turned, the thread pulls the screw into the material it is being screwed into, allowing it to hold on tightly.

Because of this design, screws are able to reduce the amount of force needed to hold an object in place. This is because the force applied to the screw is spread out over a larger area, making it easier to turn the screw and insert it into the material.

In conclusion, when using a screw to hang a picture or any other object, remember that it is an inclined plane wrapped around a cylinder, designed to reduce the amount of force needed to hold an object in place.

Answer: The answer is B! <3

Explanation:

When Blake puts a screw into his wall, it is a good description of an inclined plane. The threads of a screw act like an inclined plane to increase the distance over which you exert the input force. As the threads of the screw turn, they exert an output force on the wood, pulling the screw into the wood. So the answer is B. I hope this helped! :)
