Producing fewer eggs than the Lack number can be explained by (select all that are correct)   Question 4 options:   Egg production is never lower than the Lack number   Trying to avoid attracting a predator   Gene flow   Yearly variation in the environment   Producing larger eggs

Please Answer for each

In the graph below is shown the relationship between the number of offspring produced and the average size of offspring produced. What is the term for this relationship? 14 13 Average size of offspring produced (g) 12 11 10 2 Trade-off 4 6 8 Number of offspring produced O Norm of reaction 10

The second assumption in formulating Lack's (1947) hypothesis is that clutch size affects only offspring survival.  The data that are presented in the figure were obtained in an experiment conducted by Schluter and Gustafsson in 1993 to test this assumption.  The researchers removed or added eggs to nests and monitored the offspring that hatched from the nests, recording subsequently the reproductive output for offspring females after they had matured. i. Females reared in nests from which eggs had been removed produced larger clutches. ii. Females reared in nests into which eggs had been added produced smaller clutches. iii. Observations described in statements i and ii are consistent with the second assumption. iv. Observations described in statements i and ii reveal a trade-off between offspring quantity and quality.   Question 3 options:   A)  All statements convey accurate information.   B)  Statements i and ii convey…

A wetland is filled in in order to build some beachfront properties. This wetland was a stopping point for migratory birds along their migration (not an ultimate destination). What is a likely outcome of this scenario? The birds may experience fatigue/weakness/hunger from a lack of a resting point, which could have negative fitness consequences The birds will adjust their ultimate destination closer to make up for the missing "rest stop" The birds will be unaffected and simply go to the next wetland they encounter The birds will simply rest in the same area, just on buildings instead of in a natural habitat

Each August, dolphins near the coast of the Atlantic ocean. In a hypothetical situation, an initial population of 900 dolphins gives birth to 390 tiny babies, and during the next 12 months, 60 dolphins die. Assuming the dolphin population grows geometrically, what will the dolphin population be in 12 years?
