The diagram shows an animal cell. which letter marks the location where carbon dioxide is produced during respiration? w x y z

Answer : The correct option is 'X' (mitochondria).

Explanation :

In the given animal cell diagram,

W represent the vacuole.

X represent the mitochondria.

Y represent the nucleolus.

Z represent the cytoplasm.

The function of vacuole, it stores waste products and balance the pH level of the cell.

The function of mitochondria, most of the respiration reaction occurs in which carbon dioxide is produced by utilizing oxygen.

The function of nucleolus, it contains the hereditary information.

The function of cytoplasm, most of the chemical reaction occurs.

Therefore, the correct answer is 'X' (mitochondria).

The answer is X. I tried it it works.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
