Which process releases heat?

A. Grilling vegetables

B. Frying an egg

C. Boiling water

D. Setting off a firecracker

Answers

Answer 1

Hello there!

Question: Which process releases heat?

Explanation: The process the releases heat is called the exothermic process while the process is which heat is absorbed or taken is is called the endothermic process. The answer choices are examples of either endothermic or exothermic processes.

Answer Choices:

A. Grilling Vegetables

B. Frying an egg

C. Boiling water

D. Setting off a firecracker

Correct Answer:

D. Setting off a firecracker

Reasons:

A would not be correct since grilling vegetables is an endothermic process in which heat is being taken in to grill the vegetables.

B would not be correct since frying an egg is again taking in heat to fry the egg which is again, an endothermic process.

C would not be correct since boiling water is taking in heat to heat up the water which makes it endothermic process once again.

D would be correct since it is releasing heat when the explosion is triggered and you can feel the wave of heat afterwards.

P.S: These are all chemical reactions except for boiling water since that is a physical change.

What are the organelles in the cell?

I can see that your question has to do with the organelles in the cell but I don't quite get the analogies that you intend to use. However, I would explain the organelles one after the other.

Endoplasmic reticulum: The endoplasmic reticulum (ER) is a network of membranous tubes and sacs within the cytoplasm of eukaryotic cells. It serves as a transport system for proteins and lipids, as well as a site for folding and modification of newly synthesized proteins.

Ribosomes: Ribosomes are complex molecular machines that are found in the cytoplasm of all living cells. They are responsible for synthesizing proteins from amino acids, which are the building blocks of proteins.

Mitochondria: These are organelles found in the cytoplasm of eukaryotic cells. They are often referred to as the "powerhouses" of the cell because they are responsible for producing most of the cell's energy in the form of ATP (adenosine triphosphate).

Vacuole: Vacuoles are membrane-bound organelles found in eukaryotic cells. They are large, fluid-filled compartments that serve several important functions within the cell, including storage of nutrients and waste, regulation of the cell's water balance, and maintenance of cell shape.

Cytoplasm: Cytoplasm is the gel-like substance that fills the interior of eukaryotic cells, excluding the nucleus. It is a complex mixture of water, ions, organic molecules, and a variety of cellular structures, including organelles such as mitochondria, ribosomes, endoplasmic reticulum, and lysosomes.

Lysosomes :Lysosomes are membrane-bound organelles found in eukaryotic cells. They are referred to as the "garbage trucks" of the cell because they are responsible for breaking down and recycling cellular waste and unwanted material.

Explanation:

their genetics come from the same two parents so if their genetics looked different it would mean that a offspring wasnt one of the parents.

To solve this, we must know each and every concept behind reproduction. Therefore, all the offspring of a set of parents have identical genes best describes this kind of reproduction. the correct option is option B.

What is reproduction?

The process through which organisms duplicate themselves is known as reproduction. In general, reproduction is among the most essential notions in biology: it involves creating a replica, a likeness, and so ensuring the survival of species.

Their genetics are derived from the exact two parents, thus if their genetics differed, it meant that an offspring was not one of the mom and dad. "All the offspring of a set of parents have identical genes"  best describes this kind of reproduction.

Therefore, all the offspring of a set of parents have identical genes best describes this kind of reproduction. the correct option is option B.

What happens to air pressure and amount of oxygen as the altitude increases in Earth's atmosphere? 1. Air pressure decreases, while the amount of oxygen increases. 2. Both air pressure and the amount of oxygen increase. 3. Air pressure increases, while the oxygen decreases. 4. Both air and oxygen decrease.

Answers

Answer:

As altitude increases in Earth's atmosphere, both air pressure and the amount of oxygen decrease.

At sea level, the air pressure is about 1013.25 millibars (mb) and the concentration of oxygen is about 21%. As you go higher in the atmosphere, the air becomes thinner and less dense, so the air pressure decreases. At the same time, the concentration of oxygen also decreases because there is less air overall to contain oxygen molecules.

This is why it is harder to breathe at high altitudes, such as on a mountain. The air is less dense, so there are fewer oxygen molecules per breath and the body has to work harder to get enough oxygen.

Answer:4: Both Air and Oxygen decrease.

Explanation:This is in accordance with Henry's law. As pressure decreases solubility of gases decreases. Air pressure decreases as we altitude increases and the decrease in oxygen level is the consequence ,

So if we have the primary producers having 100% energy efficiency level from the sun, and primary consumers only get 10% by eating primary producers, etc., then a pex predators get the least; they only get 0.01% of the sun's energy.

Newton's second law of motion is F = ma.

A net force of 60 N north acts on an object with a mass of 30 kg. Use Newton's second law of motion to calculate the amount of acceleration the object will experience. Then explain how the amount of acceleration will change if the net force or the mass of the object increases?

Answers

Answer: The acceleration of the object is 2m/s^2. If net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

Explanation:

Force is defined as the product of object's mass and acceleration.

Mathematically,

F = ma     ......(1)

or,

a = F/m      .....(2)

where,

F = Force exerted on an object = 60N

m = mass of an object = 30kg

a = acceleration of the object = ?

Putting values in above equation, we get:

a = 60 kg.m/s^2/30 kg = 2m/s^2

The acceleration of the car is 2m/s^2.

From equation 2, it is visible that acceleration is directly proportional to force. This means that \if force increases, acceleration also increases.

And acceleration is inversely proportional to mass of the object. This means that if mass increases, the acceleration decreases.

Hence, if net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

A net force of 60 N north acts on an object with a mass of 30 kg , so according to Newton's second law of motion the acceleration of the object would be 2 m / s²,the amount of acceleration would decrease if the mass of the object increases.

What is Newton's second law?

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

F =m × a

As given in the problem, a net force of 60 N north acts on an object with a mass of 30 kg.

60 = 30 × acceleration

acceleration = 60 / 30

                     = 2 m / s²

Thus, the acceleration of the object would be 2 m / s² , and the acceleration would decrease if the mass of the object increases.

HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?

Answers

Answer:
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
Speed = 0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
