Answer:
Chemical properties of water are neutral pH and weak ionization while physical properties of water are that it is present in solid , liquid and gas form and it is a tasteless and odorless molecule.
Explanation:
Water is also called universal solvent due to its polar nature. Water has a neutral pH when it is present in pure form but with the addition of salts and other impurities, pH of water changes. Water has weak ionization rate. Water is present in liquid form at room temperature but increasing in temperature , they transform in gaseous state.. Water is a taste less molecule and having no odor or smell.
According to Mendel's experiment if we construct a punnet square the expected ratios should be 9:3:3:1. From our experimental results,
purple smooth = 75 ( 0.56) the expected is 0.56
white smooth = 28 ( 0.21) expected is 0.19
purple wrinkled= 24 (0.18) expected is 0.19
white wrinkled = 8 (0.06) expected is 0.06
From this results we plug the observable and expected values in a chi-square which is used to account for the differences between the expected and observable values. Then we conclude that the deviation of the observable value from the expected value is probably due to random sampling error and therefore we accept the hypothesis, such that the results are in consistent with the law of assortment.
Answer:
They are genetically identical to the parents and only differ if a genetic mutation occurs.
Sexual reproduction involves two parents and produces offspring that are genetically unique.
The greater the genetic variation, the better change that an individual in the population have a favorable gene that can help survival. Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population.

Answer:
Nutrients for growth and a safe environment.
Explanation:
“Medium” is just the term for the local environment. It may be a gel (agar) or a liquid solution. It “cultures” the cell – meaning it is intended to provide an local environment suitable for growth.
The specific compounds put into the culture medium are intended to promote the growth of the living cell.
