Answer
Frequency of stimulus can change the force of muscle twitch.
Explanation
Twitch is tension produced by the contraction of a small muscle or it is muscle fasciculation. Its strength depends on the stimulation frequency. If the frequency is higher then temporal summation takes place and produce higher tension in the muscle. If the frequency is weak then less tension is produced in the muscle. This force also depends on the cross-sectional area of muscle.
Answer:
In the water, it would be thermal. In the tubes next to the water, it would be chemical energy, and in the light it would be light energy.

Answer:
A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
Explanation:
Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.
When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.
Answer:
Control is a group generall very important in an experiment because it allows you to eliminate and isolate these variables.
