12. What characteristic below do all fungi and animals share? *
A.Asexual reproduction
B.Heterotrophic
C.Autotrophic
D.Prokaryotic
wait... hold up... no... maybe... never.
Answer:
B
Explanation:
Fungi are more like animals because they are heterotrophs, as opposed to autotrophs, like plants, that make their own food. Fungi have to obtain their food, nutrients and glucose, from outside sources. The cell walls in many species of fungi contain chitin

Which of the following best describes the matter present in an ecosystem?
A.
New matter is continuously generated by an ecosystem in a process known as photosynthesis.
B.
The waste materials generated by one organism are often reused by other organisms.
C.
The total amount of matter in an ecosystem is constantly decreasing due to the process of decomposition.
D.
When an organism reproduces, new matter is added to its ecosystem.
Answer:
D
Explanation:
When an organism reproduces, new matter is added to its ecosystem, is the correct answer.
Answer: It's is the second one. The waste materials generated by one organism are often reused by other organisms.
Explanation: Mass, or matter, is conserved in all physical and chemical changes. Matter is not created or destroyed within ecosystems, it only undergoes physical or chemical changes. One example of this process is that the waste materials generated by one organism are often reused by other organisms as food or nutrients.

Over the past 300 years, how did the role of the ocean change with respect to the amount of carbon dioxide in the atmosphere
Answer:
Ocean plays the role of regulator.
Explanation:
The role of the ocean change with respect to the amount of carbon dioxide in the atmosphere because oceans plays a role of regulator and balancer. When there is high amount of carbon dioxide in the atmosphere due to burning of fossil fuels and volcanic eruptions so the ocean absorb that extra amount of carbon dioxide from the atmosphere while on the other hand, when there is decrease in the concentration of carbon dioxide in the atmosphere, the ocean gives its carbondioxide gas to the atmosphere to regulate the concentration.
The CJ bacteria in the chickens at Monita Farms have a high frequency of the allele that causes FQ resistance. If genetic drift was the cause, would this allele also be in bacteria at the Original Farm?
Answer:
Yes
Explanation:
Genetic drift refers to a random change in the allelic frequency of a population through many generations. The founder effect is an especial case of genetic drift. Yes, the resistance allele was also at the Original Farm.
--------------------------------------
Before answering, let us review some framworks.
Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population. Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition.
The exposed example refers to a founder effect -genetic drift- event.
Some chickens were taken from the original population to another farm.
Bacteria in these chikens could or could not be genetically representative of their original population.
What does it mean?
It means that probably the allele that causes resistance was present in the original population.
Individuals carrying the allele were taken to the new farm where it randomly increased its frequency.
So in the new farm the new population expresses a high frequency of the resistant allele.
