How does a marathon runner use oxygen and produce carbon dioxide during the marathon?

Answers

Answer 1

is ther a tutor available can you plese check

Answer 2

Answer:

The carbon dioxide breathed out is a by-product of the process of cell respiration, as is water. In this process, energy is produced in the mitochondria of cells. ... When that reacts with oxygen (O2) in the cells, it produces carbon dioxide (CO2) and water (H2O). C6H12O6 plus 6O2 gives 6CO2 plus 6H2O plus energy.

In the cell cycle typical cancer cells, mutations have most likely caused
A.uncontrolled growth
B.a halt in cell division
C.a failure in mitosis
D.slower growth

Answers

Answer:

This process is akin to searching for the proverbial needle in a haystack, because many of the mutations present in these cells have little to nothing

Explanation:

During mitosis, normal cells undergo checkpoints that monitor the fidelity of the processes that occur during the cell cycle. Uncontrolled cell growth refers to the breakdown of these regulatory checkpoint mechanisms.

In the cell cycle of typical cancer cells, mutations most like cause UNCONTROLLED GROWTH (Option A).

Apoptosis refers to the programmed cell death that prevents the uncontrolled growth of cancer cells.

In cancer cells, genes that control apoptosis during the cell cycle suffer mutations, thereby leading to uncontrolled cell growth.

In conclusion, in the cell cycle of typical cancer cells, mutations most like cause UNCONTROLLED GROWTH (Option A).

Which toy car had the greatest applied force?
A 1
B 2.
с 3
D4

Answers

Answer:

the answer is 4

Explanation:

i dont know how to explain it but i took the test and it was right.

The car with the greatest applied force is : ( D ) Car 4

Given that :

Force applied is calculated as : Mass * acceleration

Calculating the force applied on each car

For Toy car 1

mass = 0.19

acceleration = 0.15

Force = 0.19 * 0.15 = 0.0285 N

For Toy car 2

mass = 2.0

acceleration = 1.5

Force = 2 * 1.5 = 3 N

For Toy car 3

mass = 0.25

acceleration = 0.21

Force = 0.25 * 0.21 = 0.0525 N

For Toy car 4

mass = 2.5

acceleration = 3

Force = 2.5 * 3 = 7.5 N

From the answers above the car with the greatest applied force is car 4 with a force of 7.5 N

Hence we can conclude that The car with the greatest applied force is : ( D ) Car 4

What conclusions can be drawn about the existence of carbon-12, carbon-13, and carbon-14? A) These are forms of carbon and they accommodate 6 neutrons and 6 electrons but each contains a difference number of protons - 6, 7, and 8 respectively. B) These are configurations of carbon and they have 6 protons and 6 neutrons but each contains a difference number of electrons - 8, 7, and 6 respectively. Eliminate C) These are isotopes of carbon and they all contain 6 protons and 6 electrons but each contains a difference number of neutrons - 6, 7, and 8 respectively. D) These are allotropes of carbon and they consist of 6 protons and 6 electrons but each contains a difference number of neutrons - 8, 7, and 6 respectively.

Answers

Answer:

C.

Explanation:

All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).

Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.

In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.

In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.

In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.

Answer:

These are isotopes of carbon they both contain 6protons and 6electrons but each contains a diff about of neutrons 6,7 and 8 respectively

A researcher observes the enzymatic polymerization of an organic molecule in a cell. Which enzyme is
MOST likely responsible for catalyzing the reaction?
A. a protein
O B. a nucleic acid
O C. a lipid
D. a carbohydrate

Answers

Answer:

A. a protein

Explanation:

Proteins function as enzymes in most of the catalyzing reactions, that increases the rate of reaction within cell.

Proteins are consist of multiple numbers of amino acids and the twisting and folding amino acids provide a unique identity to enzymes. Not all the proteins are enzymes but all the enzymes are proteins.

For example: Trypsin, Pepsin, and Lipases.

Hence, the correct option is "A. a protein".
