Answer:
If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color:
Independent: <u>temperature</u>.
Dependent: <u>leaf color</u>.
Other variable(s): According to the information, <u>there are no other variables</u>.
Explanation:
When formulating a hypothesis, it is inevitable that the presence of variables on which the hypothesis is formed is established. The hypothesis raised is the <u>effect of temperature on the color change of the leaf of a plant</u>.
The<em> independent variable</em>, used in research work, is an element that does not depend on other variables but can influence the behavior of the dependent variable. In this case, the independent variable is the temperature. In addition, the independent variable can be managed to observe its effect on other variables.
An <em>dependent variable</em> is a characteristic that is influenced or modified by the presence of other variables, such as the independent variable of a study. In this case is the color of the leaf of a plant.
Answer:
I. evolved from ancestors that walked
Explanation:
Whales and pythons have vestigial structures, which are structures (hind legs) which are no longer useful to them since they have evolved. The ancestors of the whale and python did use the hind legs but over generations the whale and snake have adapted to new environments and they no longer need them.
109 exact :D hope this helped! Have a good day
