Viruses are infectious agents, often highly host-specific, consisting of genetic material surrounded by a protein coat. Viruses are not alive, they cannot grow or multiply on their own and need to enter cell and take over the cell to help them multiply. Fungi – these are members of a large group of eukaryotic organisms that includes microorganisms such as yeast and molds, as well as the more familiar mushrooms. Fungi can be single-celled, multinucleated, or multicellular organisms. Although they are eukaryotes like plants and animals, the major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants, which contain cellulose.
The fact that 95% of iTunes sales are singles suggests that albums are overserving customers that only desire certain songs; they aren’t willing to pay $14.99 for a full album, but will pay $0.99 per song. Piracy is another concern. Though not necessarily a substitute for album purchases, the case states that 20 songs are illegally downloaded for every 1 that is purchased; this large discrepancy suggests that some customers still value full albums, but are unwilling to pay $9.99 or more. Additionally, the recording industry is overserving consumer needs – previously, they played an important role in identifying new artists and marketing their music to fans. With the dawn of social media, there are other channels – websites, MySpace, and iTunes, to name a few – that provide consumers with the ability to search out emerging artists without the help of record companies.
Most viruses are too small to be seen directly with a light microscope. Viruses infect all types of organisms, from animals and plants to bacteria .Viruses are not considered living because they are unable to reproduce.All viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell. Fungi: These are Eukaryotes..when compared to bacteria(prokaryote) and virus.Like plants and animals, fungi are eukaryotic multicellular organisms.Fungi are multi-cellular organisms and parasites are any vectors that require a living host in order to live/reproduce. Both bacteria and fungi can survive on their own, while viruses have to infect a host to survive Parasites: A parasite is an organism that lives on or inside another organism to the detriment of the host organism. These are of various forms and types.A parasite is an organism that lives on or in a host and gets its food from or at the expense of its host.
Ch 18.1 Assessment Questions (pg 515) 1a. Identify two goals of systematic. To assign each species a unique, universally accepted name; to organize living things into groups that have biological meaning 1b. Why do the common names of organisms – like daisy or mountain lion – often cause problems for scientist? (Why does it cause a problem?
Anything outside the range cannot be made using the lumber that the company has on hand. On the x axis 200 is the most modern rocking chairs the company can make, and the 250 is the most classic rocking chairs that can be made. Also by looking at the graph you can see that any
To support their hypothesis Beadle and Tatum showed that some of the mutants forms of Neurospora could not live without a particular amino acid or vitamin added to their food source. These mutants were shown to be missing one particular enzyme which led to a blocked metabolic pathway. They showed that the mutation of a particular gene precented the production of a particular enzyme- the one gene-one enzyme hypothesis. Explain why the one gene-one protein hypothesis was modified to one gene-one polypeptide. It was shown that some proteins consisted of several different polypeptide chains and each different polypeptide chain has its own gene, e.g.
_ Instead of staying behind the morning of the trip, the grandmother is the first one in the car. While traveling the grandmother tells the children a made up story about a plantation house that she had once visited with a secret panel only to excite the children so they would beg their parents to visit it. After a trip down the long dirt road the grandmother realizes that the plantation house was not in Georgia but in Tennessee. Too embarrassed to admit her mistake she causes her cat who she secretly concealed into the car jump out onto her son Baily who is driving. He then crashes the car into a ditch and the family is stranded.
There are debate argue that people are shaped by biology and genetic such as eye colour. What is the meaning of ‘Nurture’? ‘’The sum of environmental influences and conditions acting on an organism’’. Also from the ‘Oxford dictionary. For example, a teenager who has friends that are aggressive.
The experimental method is a study of cause and effect. It differs from non-experimental methods in that it involves the deliberate manipulation of one variable (the independent), whilst keeping all other variables constant and specifically measuring the dependent variable. After an experiment is performed a statistical analysis of the results allows conclusion to be drawn between the relationship of the variables based on rejecting either the research hypothesis or the null hypothesis. The experimental method splits three different types, a field experiment (an experiment conducted in the natural environment), a natural or quasi experiment (when the independednt variable is natrurally occurring outside of the experiment) and finally a lab experiment. A lab experiment is different as it is in a controlled environment with control over the independent variable as well as all confounding variables, the dependent will be being measured.
During the duration of this particular experiment, airplane and multiplication firms weren’t completely parallel to the Coase Theorem for this simple reason: they were using capital (or participation points, in this case) as the airplane firm’s compensation for the multiplication group’s paper use and by default, were destined to make a decision to become a joint venture in order to benefit both firms—even if it wasn’t completely summed up by Coase’s Theorem.
