Answer:

The correct answer is-

Hypothesis: Antibiotics cause weight gain in cows.

Independent Variable: Antibiotic pill

Dependent Variable: Weight of cow

Control Group: a group of cows gets a placebo pill

Experimental Group: a group of cows gets an antibiotic pill

Explanation:

The Independent variable is the variable that causes the response from the dependent variable or affects the dependent variable in this study the antibiotic pill affects the weight of cows so The independent variable is an antibiotic pill and the dependent variable is the weight of cows.

The control group is the group of subjects that did not get the treatment in a scientific study in the case of this study group of cows that receives the placebo pill is the control group and the experiment group is subjects that receive the treatment which is a group with the antibiotic pill.

If different masses of water are heated to the same temperature, the sample that will absorb more energy will be the mass of water with the greatest amount of water mass, because the larger the material, the greater the amount of heat needed.

<h3>What is the specific heat of water?</h3>

Water has a specific heat of 1 cal/g. ºC This means that the energy of 1 cal is required for a variation of 1 °C in 1 g of water.

With this information, we can conclude that Water's specific heat power is 4.2 joules per gram per Celsius degree or 1 calory per gram per Celsius degree.

Of the choices below, which best describes the effect predation has on the predator/prey organisms involved in the relationship?
steposvetlana [31]

Answer:

The correct answer is C. benefit ... harmed

Explanation:

Predation is a type of interaction between two individuals in which one individual gets harmed which is called prey and another organism who is predator gets benefitted.

In predation, the predator kills its prey and consume it to survive. For example, Lion is a predator and deer is the prey so during predation lion kills the deer and consume it so here lions get benefited by consuming deer and deer is harmed as it lost its life. So the correct answer is C. benefit ... harmed.

Radiation is a method of thermal energy transfer that moves-
Montano1993 [528]

Answer:

-heat

Explanation:

Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.

Good luck!!
