Monarch butterflies are a migratory species that flies south once during the lifetime of an individual. One specific population flies to Cuba, where it encounters and shares habitat with resident monarchs that do not migrate and stay within Cuba their entire lifespan. The table shows comparisons between the two populations. What data indicate the greatest difference between the populations? A. Male to female ratioB. Difference in wing sizeC. Higher mean weightD . Average of wing angle

Which of the following are reasons why parental investment can differ between the sexes?   a. Production of different sex cells   b. Differences in behavior   c. Differences in migration   d. Both a. and b.    e. Both b. and c.

A student is studying the migration pattems of several birds. She collects the data in the table. Distancs Traveled (on) 276 3.0 4.5 10.0 25.0 1.909 2,356 1 What conclusion can the student make? (SC.5.N.1.1) O The distances bird travel is independent of their size. o Birds more than ten grams in weight are more likely to travel. o The smallest bird traveled the greatest distance. O The largest birds stay in the same habitat all year.

Under which scenario can a hawk successfully invade (or persist among) a population of doves? O F) Options A, B, and C O D) Options A and B O C) Lowest resource value (V « C) O A) When high resource value relative to cost (i.e., V = 2*C) O B) Lower resource value relative to cost (i.e., V>C and V< 2*C) O E) Options B and C

Please select all of the answers that are  reasonable interpretations of this figure looking at the mortality of seedling vs the mass of seeds for different species. A. The chestnut blight caused chestnuts to make heavier seeds than any other species B. The proportion of seedlings that survive is better in trees with large seed mass C. There a appears to be a tradeoff. Species that invest a lot of resources into an individual seeds produce fewer seeds that survive well. Species that invest resources in and produce a larger number of lighter seeds produce seedlings with greater probably of dying D. It appears that early-mid successional trees invest more heavily in the number of seeds than the size of seeds E. The proportional survival of tree seedlings is higher in less heavy seeds F. It appears that late successional shade tolerant trees invest more heavily in the number of seeds than the size of seeds
