Trout are a type of fish that live in freshwater ponds and streams. raychelle did an investigation to see how the amount of nitrogen in pond water affects the number of trout in the water. she tested the water of 20 different ponds in her city. each one had a different amount of nitrogen in it. she then did a study to determine the number of trout in each pond. she compared the amount of nitrogen to the number of trout in each pond. what was raychelle's dependent variable?

The correct answer will be- number of trout in ponds

Explanation:

A scientific experiment is designed in a way that it tests the hypothesis and contains three different types of variables: the independent variable (which can be manipulated), dependent variable (which is tested in the experiment) and constant ( which is kept same throughout the experiment).

In the given question, since the researcher wants to study the effect of nitrogen on the number of trouts in which the variable to be studied is the number of trout which depend on the concentration of nitrogen in water bodies.

Thus, a number of trout in ponds is the correct answer.

answer: cannibalism, the capac raymi, capacocha, the eight day feast, the combing of the hair

explanation:

the incas have many rituals, cannibalism was always a very ritual thing, which was normally tied to sacrifices, warfare, death, and regeneration.

  the capac raymi was one of the most important ceremonies. it occurred around the summer solstice and was when they worshiped their sun god, also known as inti.

  the capacocho was another one of their most important ceremonies. it was when many children where selected to start their training, and these children where destined to become sacrificial blessings to their sun god, inti. being chosen for this ritual was a blessing.

  the eight day feast was a feast that lasted 8 days and, each day, the day began with a chanting at dawn. a follow up song at noon. which ended with complete silence at the end of the day. on this day, inca royalty was always dressed in silver and gold laced clothing.

  the combing of the hair was the most important ritual to young girls. this ritual was known as the coming of age ceremony, but only the most beautiful girls where chosen. in this ceremony, the girls chose their new name and where chosen as either brides, or princesses of rulers.
