Question 1 (1 point) Which of the following would be a good hypothesis for today's lab? Male bean beetles prefer mung beans over black eyed peas. Female bean beetles prefer large beans because they provide food for grubs. Female bean beetles prefer smaller beans because they provide more nutrition. Male bean beetles prefer larger beans because they live inside of them. Question 2 (1 point) How does measuring the volume of a bean help us test our hypothesis? To see how much water is in each bean More volume in a bean means more food available for a beetle grub Knowing the volume of a bean helps us calculate the t-statistic Knowing the volume of a bean tells us the p-value Question 3 (1 point) 70 mm is equal to which of the following in meters? 7000 m 700 m 0.7 m 0.07 m

QUESTION 25 Base your answers to the questions on the microscope image below: What structures allow this organism to move (and they help in eating too)? What is the name of the process in which this organism eats? True or false: This organism contains an organelle called a contractile vacuole.

A student performed an experiment using dry, non-germinating seeds to measure the rate of cellular respiration. She then watered the seeds so they began to germinate and performed the experiment again. Finally, she allowed the same seeds to grow into leafy green plants and performed the experiment one last time. Assuming the mass, temperature, and pressure were kept constant, which experiment would you expect to cause the volume of oxygen to decrease at the fastest rate?

Question 21>In 1668, Francesco Redi performed a series of experiments on spontaneous generation. He began by putting similar pieces of meat into eight identical jars. Four jars were left open to the air, and four were sealed. He then did the same experiment with one variation: Instead of sealing four of the jars completely, he covered them with gauze (the gauze excluded the flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (young flies) appeared in the meat.What hypothesis was being tested in the initial experiment with open versus sealed jars?A.The type of meat used affects the likelihood of spontaneous generation.B.Spontaneous generation can occur only if meat is exposed to air.C.Spontaneous generation is more likely during the long days of summer.D.Maggots do not arise spontaneously, but from eggs laid by adult flies.

To conduct their experiment, the researchers collected L. peronii eggs from a natural stream.  After the eggs had hatched, tadpoles were raised in artificially constructed 2 L containers in a laboratory.  All containers were filled with 1 L of filtered tap water, and the water was changed every other day.  Thirteen tadpoles were placed in each container, and the tadpoles were exposed to a 12-hour light: 12-hour dark photoperiod.  All tadpoles were fed thawed spinach daily.  The researchers randomly placed the tadpoles into containers exposed to one of four treatments, with nine replicates of each treatment, as follows: Low UVBR (<6.0 kJ/m2), low temperature (15OC) Low UVBR (<6.0 kJ/m2), high temperature (26OC) High UVBR (>70.0 kJ/m2), low temperature (15OC) High UVBR (>70.0 kJ/m2), high temperature (26OC) The researchers recorded the number of tadpoles still alive out of the original 13 in a container (percent survival) at different time periods.  Their results at Week 4,…
