1.) Lynx mate in March and have litters of 3 to 5 kittens in May. Lynx kittens are born blind and naked . Their eyes open after 10 days. In 12 weeks , the kittens travel with their mother. They watch and learn how to hunt for hares. Their eyesight is more acute than their hearing or sense of smell. Lynx are active at night (nocturnal).
Hares have litters of 2 to 4 offspring, with up to 4 litters over a summer. Hares are born with their eyes open and bodies fully haired. Birth weight doubles in 8 days. Hares use their good hearing and super sensitivity to ground vibrations, as well as speed and coordination, to escape lynx. Hares are active at night and spend the day grooming and resting.
A.) Classify the lynx as a r- or K-selected species . Provide evidence from the information given to support your choice .

Polygyny is a common mating system in nature. Which one of the following scenarios is LEAST likely to result in a polygynous mating system?
Male stalk-eyed flies form leks where receptive females come visit
Male Neotropical giant damselfly defend water-filled tree holes, which are the oviposition sites for females. Suitable tree holes for oviposition are rare and females must mate with the resident male in exchange for access to the oviposition sites.
Male Bengal tigers defend large territories that contain food sources. Female Bengal tigers visit male territories to mate. The density of the Bengal tiger is extremely low that male tigers rarely encounter more than one female in their lifetime.
In the bumblebee-wolf Philanthus bicinctus, females are unreceptive until they finish constructing the long underground burrow as nest sites. Males search for locations containing a number of newly constructed burrows and attempt to control these sites against the intruders.

- Answer the following questions using this information: Bowhead whales can live up to 150 years, reproducing first when they reach 25 years of age, which is when they leave their mother. The survival curve for this whale species is shown below. Indicate which answer is correct about this whale. % alive age in years 150 O They have a type 1 survival curve and show little parental care of offspring. O They have a type 2 survival curve and show strong parental care of offspring. They have a type 1 survival curve and show strong parental care of offspring O They have a type 3 survival curve and little parental care of offspring.arrow_forwardIdentify whether each of the following scenarios is most likely to result in stabilizing, disruptive, or directional selection a) Beetles that emerge from hibernation too early are more likely to killed by frost, those that emerge too late will miss the chance to mate [Select ] b) Frogs with mating calls that are between 400 and 600 chirps per minute attract more mates than frogs with calls that are lower than 400 chirps per minute or greater than 600 chirps per minute [ Select ] c) Plants with the largest leaves are better able to gather sunlight in the rainforest [ Select ] d) Giraffes with longer necks can reach more leaves, but they have a harder time pumping blood from their heart up to their brain [Select] e) Mice with the lighter fur are better camouflaged from predators than mice with darker fur V [ Select ] stabilizing selection disruptive selection directional selectionarrow_forwardWhich of the following statements is NOT the reason why females are choosy? By being choosy, she can acquire advantageous genotypes for her offspring from her mates. By being choosy, she can acquire resource for her offspring from her mates. By being choosy, she can ensure that her male offspring can attract more females as well. Her seeming choosiness is a by-product of her stereotypical behaviors exploited by the males for mating gains. All listed above are reasons why she is choosyarrow_forward

- In a species that has a monogamous mating system, which situations is most likely regarding the lifetime reproductive potential of males and females? they are similar it is much higher in males than in females it is much higher in females than in males there is no consistent pattern in this type of mating system 9:24 PM 11/29/2020arrow_forwardWhich of the following statements is true about certainty of paternity? Question 12 options: Certainty of paternity is low when egg laying and mating occur together, as in external fertilisation. Certainty of paternity is high in most species with internal fertilisation because the acts of mating and birth are separated by time. Certainty of paternity is low when males guard females they have mated. Paternal behaviour exists because it has been reinforced over generations by natural selectionarrow_forwardPlease Aspaarrow_forward
- In 1983 a population of dark-eyed junco birds became established on the campus of the University of California, San Diego (UCSD), which is located many miles from the junco's normal habitat in the mixed-coniferous temperate forests in the mountains. Juncos have white outer tail feathers that the males display during aggressive interactions and during courtship displays. Males with more white in their tail are more likely to win aggressive interactions, and females prefer to mate with males with more white in their tails. Females have less white in their tails than do males, and display it less often. (Pamela J. Yeh. 2004. Rapid evolution of a sexually selected trait following population establishment in a novel habitat. Evolution 58[1]:166-74.) Refer to the paragraph on dark-eyed junco birds. The UCSD campus male junco population tails are about 36% white, whereas the tails of males from nearby mountain populations are about 40-45% white. The founding stock of UCSD birds was likely…arrow_forward6. All of the following statements about mating behavior are correct except: Intersexual selection describes females choosing males based on traits that indicate superior fitness compared to other males intrasexual selection results in selection for traits that help a male be superior in competition with other males the mating relationships of most birds appear monogamous from behavioral observations the mating relationships of most mammals are monogamous to ensure reproductive success of the pair polygamous relationships most often involve a single male and many females, but in some species that is reversed.arrow_forwardPlease solvearrow_forward
