Prokaryote DNA replication is a semi conservative, bidirectional, template driven process. The phrase ‘semi-conservative’ refers to the fact that the newly synthesised double stranded DNA is made up of one parental (existing) strand, and one newly synthesised strand. The parental duplex is not ‘conserved’ as an entity. This was proved by the Meselson-Stahl experiment by replicating E.Coli in different mediums of of different Nitrogen isotopes. The results consisted of half of normal weight and half with intermediate weight, proving an immortal strand serving as an unchanging template.…
The purpose of this lab is to examine cross sections from the leaves of C3 and C4 plants and to determine the morphological differences between them while relating those differences to their metabolism. In C3 plants the carbon dioxide is first incorporated into a 3-carbon compound. Their stomata are open during the day and photosynthesis takes place throughout the mesophyll cells. In comparison C4 plants, the CO2 is first incorporated into a 4-carbon compound. Their stomata are open during the day and photosynthesis takes place within the inner cells.…
Assignment 3.05 DNA DNA, deoxyribonucleic acid, is the stuff in humans and almost all other organisms. About every cell in you and everyone else's body has the same DNA. DNA is usually located in the cell nucleus (nuclear DNA),however small amounts of DNA can be found in the mitochondria (mitochondrial DNA or mtDNA). The DNA has information stored as a code created by four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Each base is connected to a sugar molecule and phosphate molecule.…

Rhetorical Analysis of Apes of Wrath Barbara Smuts is a reputable psychologist and anthropologist who teaches at the University of Michigan, she is a connoisseur in the social behavior of animals such as primates. In this essay called “Apes of Wrath” which was first published in 1995, Barbara Smuts makes detailed and relevant connections between her animal observations and that from human’s social relationships. When discussing genetics, humans and primates are almost exact, in addition, Smuts makes inferences about how impeccably analogous their social aspects are. Smuts observed how male primates would attack females and she became interested in knowing why this would occur. She soon realized this forcefulness was a way in which male primates would establish…
1) These statistics do not come as a shocker because the breeds that are affiliated with these deaths are the same breed that are abused, forced to fight, attack, and obey the commands of their frightening owners. Victims that survive pit bull mutilation incidents live with grudges towards the breed type itself not giving the group a chance at defense. These victims will never agree that pit bulls are falsely accused of crimes, and that the real criminals are the owners. This breed is not born aggressive their only crime is trusting in owners that force them to commit atrocious crimes.…
She also learns how to behave by modeling their actions. The learning of aggressive behavior from the social-cognitive perspective can…
1) Explain how the Lin et al. used the catFISH technique to determine which neurons are involved in particular behaviors (3 pts) Lin et al. used catFISH (cellular compartment analysis of temporal activity by fluorescent in situ hybridization) to compare the activation of c-fos expression during two successive episodes of behavior (either the same behavior or different) in the same animal. Through experimentation, researchers discovered that animals killed five minutes after fighting expressed only nuclear c-fos transcripts, while animals killed 35 minutes after fighting solely expressed cytoplasmic c-fos transcripts. Furthermore, after two consecutive behavioral episodes (of the same behavior), separated by 30 minutes, researchers discovered…
Mindy (Mytien) Nguyen Professor Montagne Anthropology 185 03 November 2015 Innate or Learned? Aggression refers to an array of behaviors that may have consequences in both physical and psychological harm to oneself, others, or objects in the environment. It can take a variety of forms that include physical, verbal, mental, and emotional. As aggression progresses in human behavior from adolescent to adult, we often wonder if these qualities are innate in humans or if it is a learned behavior.…
HMS 105 Exam 9 question 1 Discuss differences and similarities between the social learning model and the cognitive-behavioral model. Intro A person who is trying to remain sober has many barriers to overcome. There is a “high rate of relapse during the recovery process” (Stevens & Smith, pg. 261).…
We can accept the null hypothesis that the administering of Naloxone reduces the behavior of play, which represents a specific inhibition of behavior. This can further be understood by when an opioid antagonist (Nalaxone) is administered to a rat it reduces social behavior (pins), but does not produce nonspecific inhibition of behavior (rears). Evidence is consisted with a study that was conducted by Vanderschuren, Niesink, and Van Ree that examined the significance of social play behavior in rats. Social play behavior is defined as one of the earliest forms of non-mother-directed social behavior that is found in varying species. It is believed that opiod and dopamine systems play a role in the value of reward in behavior.…
Aggression for the Ages The feeling of hate was once necessary to survive back in our evolutionary history. The emotions closely associated with hate such as anger and aggression evolved in order to aid in our successful evolutionary journey. In What’s So Bad about Hate?…
When a colleague asks how we are first thing in the morning, our answer is frequently a lie; regardless of how we feel that day and what is going on our lives, we automatically present a picture of wellness and happiness. This is just the first of many lies we will tell throughout our day, assuming we have not already lied to those we may have encountered in our household. Indeed, lies permeate our lives, and the average person [insert statistics here]. Why do we do this? What is the point of this ritual of asking each other questions that we all frequently lie about?…
A variety of evidence, from narrow studies of amity pat- terns among children to the very broadest gregarious statistics, points toward correlations between convivial omission and aggression. But what causes what? Many theorists have concluded, very plausibly, that truculent demeanor leads to convivial omission, because people disrelish associating with someone whose comportment is deleterious or disruptive. Our findings do not prove that theory erroneous, but they do fortify the antithesis direction of causality. Omission from convivial groups and relationships—even just aurally perceiving a forecast about being alone during the distant future—appears to engender a vigorous propensity toward truculent…
Background: When it comes to social and developmental learning in individual Meerkats and groups of Meerkats there are many things that come into play. There have been debates as to the evolutionary origins of culture for identifying learning mechanisms in wild, natural populations. Meerkats are small carnivore animals that belong to the mongoose family. One thing that differs them from a lot of other mammals is one Meerkat often contains a clan of about 20-50 members. Throughout time Meerkats foraging patterns and learning mechanisms have evolved and changed.…
