In a zygotic life cycle:
a. haploid cells form gametes that fuse to produce thick-walled diploid zygotes capable of surviving stressful conditions.
b. there is an alternation of generations.
c. the zygote undergoes meiosis and produces many heat-resistant spores that increase the population size and aid in dispersal.
d. haploid cells form spores that fuse to produce thick-walled zygotes capable of surviving stressful conditions.
e. none of the choices provided.

How does the molecular clock work? a. it analyzes the brain functionality of two different species.b. it examines and compares the physical characteristics of two different species.c. it illustrates relationships between two different species.d. it compares the number of mutations that exist in the dna of two different species.

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.

For this question look at the hydropic diagram water that is heated by the sun evaporates. select the number that represents it.
