This culture vial was then labelled with population size and group name. Once small population was complete, the same procedure was replicated but for the larger population, where the first twenty male flies and first twenty female flies were randomly selected to be parents for the new generation of the large population. The excess flies not used for the new generations were disposed of . Once new vials were completed the F1 phenotypes were counted to calculate allele frequencies and expected heterozygotes (2pq) and recorded. After this for the next four weeks random samples of both the small and large population were taken, the phenotypes of this random sample were counted and used to calculate the allele frequencies; all data was recorded.
Manatees swim at about 5 to 8 kilometers per hour; much speedy swimming has been known in short bursts (up to 30 km/hour). Reproduction: Female manatees reach sexual maturity between five and nine years of age. Manatees typically breed once every two years. A female manatee usually seeks quiet area in which to give birth after a gestation of about 12 months. Generally, most births are of a single calf about 120 centimeters long with about 30 kilograms weight, although a few cases of twins have been documented.
The other class other then the queen are the drones, drones are males hatched from eggs that have not been fertilized, these drones hatch and have one purpose, to mate with the future queen, these drones will be kicked out of the hive after the mating season and will die leaving food for the Harvestmen (leiobunum vittatum) that have a mutual relationship with the bees. The final class in a honey bee hive is the queen, there is only one queen in the hive at a time until a “trigger” is had, this can be a queen randomly dying, an old queen

When he first meets them and tells them where he came from, Scout becomes dubious, but Jem accepts him. After all, Dill saw Dracula. The Finch’s new friend is curious, creative, and sensitive.
Scientists take the unknown and make it known. The audience will better understand the scientific method if it seems logical. Including examples of Einstein, accepting scientific theories, and designing experiments show that the basis of Barry’s argument is factual. “Einstein refused to accept his own theory until his predictions were tested,” showing even the best of the best scientists study with uncertainty. Barry’s appeal to logos helps characterize the intellectual side of science.
In doing this, Marquis emphasizes how fragile the moth is; he has wings and Archy has a protective shell. Archy witnesses the moth trying to “fry himself” (line five) on three different lights until he finds a patent cigar lighter and succeeds in killing himself. Before he dies, the moth explains that fire is very beautiful to him, and his dream is to be united with beauty. He says, “it is better to be a part of beauty/for one instant and then cease to/exist than to
In the stories “Old Ben” by Jesse Stuart and “Fox Hunt” by Lensey Namioka flashback and foreshadowing are used as narrative structure. “Old Ben” is about how a boy and his family make friends with an unusual animal a bull snake. “Fox Hunt” is about how a Andy has to take exams. Then make friends with a girl how help him study and, they both turns out to be a spirit fox. In these stories the elements flashback and foreshadowing in similar and different way.
The article explains the phenomena of sex change in clown fish by using an unlikely event as an example, three young clownfish survive their journey into adulthood and establish a population with an unsettled anemone. Rhodes explains that two of the three fish will become male and female, while the third remains unsexual. In the event that the one female dies, the male clownfish becomes the alpha female while the unsexual third fish will become male, a process which reorganizes the gonads of the clownfish, which usually takes about two weeks. It is also mentioned that sex change does affect the behavior of the fish, with the alpha male who will eventually become female takes on the aggressive behavior of an alpha female. The author does mention that not much is known what role the brain takes in the sex change, but that it might have something to do with the excretion of hormones form the pituitary gland.
A spider that can capture a leopard, python, and other beasts, and a Coyote that can defeat the powerful Thunder? These come from two trickster tales called, “How Stories Came to Earth” and, “Coyote Steals Fire.” A trickster tale is a story featuring a protagonist, who is often an anthropomorphized animal that has magical powers and is characterized as a compendium of opposites. In the story, “How Stories Came to Earth,” there is a spider who must capture four creatures so he can get the sky god 's stories. In, “Coyote Steals Fire,” there is a Coyote, who must defeat the powerful Thunder who has all of the fire to himself, so that the Coyote can get the fire for all the animals. They have similarities and differences in who the tricksters are,
Synchronicity In Chaos A study of how a population of fireflies with different frequencies synchronise their frequencies over time Ananya Kaushik BSc. Mathematics 3rd Year SNU ID- AAA0625 Introduction I have picked the topic synchronization in chaos, more specifically I am a studying synchronicity in fireflies. A phenomenon observed by Mirollo and Strogatz in their paper ‘Synchronization of Pulse- Coupled Biological Oscillators’ is that when we see a swarm of fireflies, which start out with different frequencies of blinking, after a period of time, their frequencies get synchronized, ie, they all start blinking or glowing together. In Strogatz paper, he has discussed various applications of this
