Asap latoya wanted to discover if beans or corn would grow best in the soil in her garden. she planted beans in a corner under a tree, and planted corn in full sunlight. what were latoya’s variables? what were latoya’s controls? how could latoya have improved her experimental design?

Latoya's variables were :

Independent Variable: spot to plant the plants, under tree or in sunlight

Dependent Variable: the type of plants used

Latoya's controls were: In this experiment, Latoya didn't really have a control. A control is something to look at, something that will stay the same to look back to. A guideline.

Latoya could have improved her experiment if she gave each plant equal treatment. She would have to plant corn in the sunlight AND under the tree. She would also have to plant the beans under the tree and in the sunlight.

what is the average time it took the car to travel 0.50 meters?

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.
