Thus, the equation relates the rate of change of the population \(N\) to the current population size and is the theoretical maximum rate of increase of a population per individual.

In this procedure, you will crush a strawberry and add detergent and salt to break down the cell walls to release the DNA within the nucleus. The filtrate is then poured into a test tube and a layer of alcohol is poured over the top.

The allele for one horns is dominant over the allele for two horns. Arrange them so that the male’s set (Hh) is on one side and the female’s set (hh) is on the other side. *The M1,M2, F1, F2 labels will help you if you get them confused. Show the cross between the new parents Hh x Hh Show the cross if the parents are HH x Hh.

Forensic entomologists can measure the size of these developing fly larvae to determine “time since colonization.” Over several days the spongy brain will liquefy and leak from the ears and mouth, while blisters form on the skin which eventually evolve into large, peeling sheets.

You can locate the ventral nerve cord by removing the intestines and searching for a white stringlike structure that runs the length of the worm and attaches to the brain. ____ The pale stringlike structure running the length of the ventral side of the worm is the blood vessel.

Elephant specialists that study the elephants in this preserved area have collected data on the herds in the park. They noticed that while all the males have tusks, about 50% of the females in the park that are over the age of 20 years do not have tusks.

Start at the the tibial tuberosity (bump on your shin) to the medial malleolus, the bump on your ankle. Finally, measure your ulna length by bending your arm and measuring from the proximal end of the ulna (elbow bump) to the distal end, the styloid process of the ulna.

By 1923, the deer were reported to be on the verge of starvation and the range conditions were described as "deplorable." The Kaibab Deer Investigating Committee recommended that all livestock not owned by local residents be removed immediately from the range and that the number of deer be cut in half as quickly as possible.
