Answer:
C. experimental
Explanation:
Experimental variables are the variables that are changed during the experiments to observe the effects of these changes. An experiment usually has one or more experimental variables. An experimental variable that is changed to know its impact on some other variable is called the independent variable.
In the given experiment, goldfishes were exposed to various temperature conditions to observe the effect of temperature on respiration. Therefore, both temperature and respiration rate are the experimental variables here.
B. Reproductive organs are formed by the body
<span>Infiltration is the process by which rainwater becomes groundwater. In the water cycle, which involves primarily; evaporation, condensation and precipitation. Henceforth, after precipitation comes infiltration in the land areas leaving the rainwater aggregated in a single location which accumulates over time. Then this process is followed by runoff and subsurface flow by which water flows through other bodies of water, either in river, sea or ocean, even lake. Other rainwaters that has segregated and wasn’t able to transport itself stays in the process of infiltration, thus groundwater.<span>
Thus, solar radiation doesn't play a role in runoff or infiltration.

The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids.) The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
Answer:
the frog and cricket are eaten by snake and soil bacteria all dead organisms are eaten by soil bacteria.
The sun is the energy source for grass which is in turn an energy source for crickets and soil bactiera. Snakes and frogs eat the crickets and snakes also eat the frogs. When all the animals including grass die then will get eaten by the soil bacteria.
