Me with this 60 points,5-star rating, an and marked as branliest.

susan wondered why she heard less crickets in the fall than during the summer. she decided to investigate how temperature affects the chirping of crickets. susan hypothesized that if the temperature is decreased, then the number of chirps would decrease, then the number of chirps would decrease. she took 10 crickets and 10 containers and place a cricket in each one. she recorded the number of chirps each cricket made in one minute at a room temperature. susan gave all the crickets the same amount of food, water, and same type of container.

Independent Variable: temperature

dependent variable: chirps

Hypothesis: the lower the temperatures the less chirps

constants: temperature or food and water

repeated trails: success and failure

control:the experiment

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
