The given question is incomplete, the complete question is:

Madison lives near the ocean. She’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. If Madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: dependent variable: independent variable: one possible confounding variable:

Answer:

A variable, which is under study or observation in an experiment and changes concerning the independent variable is termed as a dependent variable. Based on the given experiment, Madison is checking the influence on the progression of corrosion of metals concerning the variations in the concentration of salt. This shows that the extent of corrosion of metals is a dependent variable.  

A variable, which can be controlled or monitored like increased or decreased, and one is familiar with is termed as an independent variable. This variable is not affected by another variable, like a change in the concentration of salt is the air may exhibit an effect on the corrosion of the metal, however, the process that is, the corrosion of metals does not affect the concentration of salt in the air. Hence, the independent variable is the salt concentration in air.  

A variable that possesses the tendency to change or influence both the independent and dependent variables is known as a confounding variable. If the airspeed is higher than it will carry the salt particles at a brisk rate and speed resulting in enhanced corrosion of metals. Likewise, if the speed of air is slower, there will be a reduction in the corrosion of metals. Hence, the confounding variable is the speed of air.

How do CAM plants fix carbon?
Snowcat [4.5K]

Answer:

CAM plants temporally separate carbon fixation and the Calvin cycle. Carbon dioxide diffuses into leaves during the night (when stomata are open) and is fixed into oxaloacetate by PEP carboxylase, which attaches the carbon dioxide to the three-carbon molecule PEP.

Which method would allow you to study the behavior of a tiger in its native habitat in India?
IgorLugansk [536]
They are solitary animals, especially males who do not live in groups, unlike the female which can form small groups of three or four members with their young.

The males are very territorial, so take care of their personal space and the females with whom they mate. To mark their territory, they spray the trees and rocks with a mixture of urine and musk.

Both male and female, they are related only in times of mating and reproduction. There have been cases where the male is responsible for feeding breeding if the mother has died.

The gestation period lasts between 98 and 108 days and give birth to two to four cubs weighing just over a kilo. They have a short life expectancy, as only get to live 10 to 12 years in the wild, but in captivity Natural mortality manage to live up to 26. It is mainly due to the fighting between males
