Students create a model to show how a swimming pool warms by convection, as shown. swimming pool
water
heater
Will the entire pool be warmed by only using one heater, and why?
Yes. The cold temperature will be transferred to the air because the warm water from the heater pushes against the cold water.
o Yes. The heater warms the water in the entire pool because it warms the water at the bottom, which circulates to the top.
O No. The heater will not be able to heat the entire pool because water is a poor conductor of heat.
O No. The water warmed by the heater remains at the bottom of the pool because it has more thermal energy,

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.

As a small change in a person's dna can cause a genetic disorder

Explain the cellular functions that occur when antibiotics attack a bacteria cell. a. antibiotics target the cell wall, cell membrane, and the processes of protein and nucleic acids production in bacteria to rupture the cell. b. antibiotics create dormant resistant endospores to preserve the genetic material and rupture the cell. c. antibiotics target the cell wall and form a bridge-like connection to form conjugation. d. antibiotics use binary fission to grow twice its size, replications its dna, and split into two cells.
