During a routine cleaning of the incubators in a college laboratory, a student accidentally increased the temperature of one incubator from 37℃ to 40℃. The next day when the students checked on the cells, they found that the cells in the incubator at 40℃ grew more than those in the incubator at 37℃. The students decided to test this observation through an experiment. (a) State the hypothesis for this investigation. (b) Identify the independent and dependent variables. *

Hypothesis: If there is an increase in the temperature the number of cells increases.

The independent variable: different temperatures.

dependent variable: number of cells.

Explanation:

The hypothesis is a possible explanation for any phenomenon that occurs in nature, which is based on prior knowledge or evidence and can be tested with the help of the scientific method.

The independent variable is a variable that is subject to change and manipulated in an investigation and affects the dependent variable, in this case, different temperatures are the independent variable.

the dependent variable is the variable that depends on the independent variable and helps in finding the result and conclusion of the effect.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

regents of the university of california v. bakke, 438 u.s. 265 (1978), was a landmark decision by the supreme court of the united states. it upheld affirmative action, allowing race to be one of several factors in college admission policy.
