Select two answers.A.Rolling a number greater than 6 on a six-sided number cubeB.A flipped coin landing on tailsC.A flipped coin landing on heads or tailsD.Picking a blue marble from a bag of 6 red marbles and 4 blue marblesE.Rolling an odd number on a six-sided number cube 13In a kidney machine, protein molecules are not lost from the bloodHow is loss of protein prevented?ABCDMembranes prevent protein molecules diffusing out of the blood.Proteins are actively transported back into the blood.Proteins do not enter the kidney machine.The dialysis fluid contains protein, so there is no diffusion gradient. According to "How to Think Like a Researcher," a chapter from How to Find Out Anything, one should begin research by asking answerable questions rather than open-ended questions. Based on the guidelines in the text, which is an appropriate research question? There is a mutation in the operator of the lac operon in a cell such that the lac repressor always stays bound to the operator. If lactose is added to the cell, what will happen? Write an inequality that represents 54 less than 1/2 of a number is more than 233 What is the y-value when x equals -16?y = -200 - 12(x) Explain and show how to find the square root of 50 to the nearest tenth Sarah wanted to find out if temperature has an effect on the growth of bread mold. She grew the mold in nine Petri dishes containing the same amount and type of nutrients. Three were kept at 0 C, three were kept at 90 C, and three were kept at room temperature, 27 C. The containers were examined and the growth of the bread mold was recorded each Friday for five weeks.

The two variables in an experiment are the _________, which is manipulated by the researcher, and the _________, which is a characteristic or measurement that resulted from the manipulation:(a) independent variable; dependent variable (b) dependent variable; independent variable The sedimentary layers of Earth increase in temperature with depth. The massive weight of these layers also causes an increase in pressure which increases the temperature even more. This cycle of heat and pressure transforming the existing rock is called the rock cycle, a system of constantly changing rock formation and melting that links sedimentary, igneous, and metamorphic rock. The hotter the temperature and pressure the greater the metamorphic changes. Depending on the conditions under which rock is changed, the rock gradient forms new metamorphic rock into high-grade or low-grade metamorphic rock Which is the slope of the line that passes through the points(2,4) and(5,1)?
