Give an example of mutualism and explain how it works.
Answer:
The bees fly from flower to flower in search of nectar, which they transform into food, which benefits these insects.
On the other hand, whenever the bees are placed on a flower, particles of pollen adhere to their body; Such particles are transported to other flowers, resulting in plant pollination.
Explanation:
Mutualism is based on a version of the labor theory of value which it uses as its basis for determining economic value. According to mutualist theory, when a worker sells the product of their labor, they ought to receive money, goods, or services in exchange that are equal in economic value, embodying "the amount of labor necessary to produce an article of exactly similar and equal utility"

why the oceanic white tip shark is a good predator
Answer: The oceanic whitetip shark is one of the most widely ranging sharks, common throughout the warm latitudes of all oceans. It lives in the open ocean, where it is a predator at the top of pelagic food webs. ... They are a primary component of shark feeding frenzies caused when mixed groups of predatory species feed together.
Explanation:
The oceanic white tip shark is an effective predator due to its powerful jaws with sharp teeth, advanced sensory organs for detecting prey, and versatile feeding behavior. These attributes collectively make it a highly skilled and adaptable predator in marine ecosystems.
The oceanic white tip shark is a formidable predator for several reasons:
Physical AttributesThe jaws of a shark are equipped with multiple rows of sharp, serrated teeth, making them highly effective at tearing into their prey. Their streamlined bodies allow for strong and agile swimming capabilities, which are crucial for both chasing prey and avoiding threats.
Sensory AbilitiesOceanic white tip sharks possess a network of sensory organs called the ampullae of Lorenzini. This system can detect electrical fields, which helps them locate prey even when it is hidden or camouflaged.
Feeding BehaviorThese sharks are not picky eaters and have been known to feed on a variety of fish and marine animals. Such versatility in diet contributes significantly to their survival as apex predators in the marine ecosystem.
Thus oceanic white tip shark is a good predator.

Would the same symptoms occur if the immune system were functioning properly ?
Answer:
The immune system can be broadly sorted into categories: innate immunity and adaptive immunity.Innate immunity is the immune system you're born with, and mainly consists of barriers on and in the body that keep foreign threats out, according to the National Library of Medicine (NLM). Components of innate immunity include skin, stomach acid, enzymes found in tears and skin oils, mucus and the cough reflex.
Explanation:
Answer: Rheumatoid arthritis is an autoimmune disorder. The immune system attacks the tissue between joints, causing the joints to distort,as seen in model 1. The joints between bones have less cartilage, as shown in Model 2. People who do not have the disease do not have these symptoms, because their immune system does not treat healthy tissue as a threat.

What makes up an owl pellet? feathers from the owl preening, or cleaning, itself pieces of food that the owl did not like pieces of food that could not be broken down by the owl’s stomach
Answer:After an owl eats the small rodents, birds, and bugs that are a part of its nightly diet, its stomach cannot
digest the fur, bones, teeth, feathers, and insect shells from that food. These “extra” parts are formed into a tight PELLET inside the owl and are then are later SPIT UP by the owl.
Explanation:
An owl pellet refers to the pieces of food that could not be broken down by the owl’s stomach.
What is a Pellet?These are the indigestible parts of the food such as the bones, fur etc which are often regurgitated.
The owl pellet will therefore make up pieces of food that could not be broken down by its stomach.

(b) Explain why DNA replication cannot proceed to the regions of the chromosome labeled as I in Figure 1B unless topoisomerase binds ahead of each advancing replication fork in region II
Answer:
The explanation is found below
Explanation:
DNA replication is an important phenomenon that must occur prior to any cell division. Before DNA replication can take place, the double-helical structure of the DNA molecule must unwind. This separation into a Y-shaped replication fork at the origin of replication (where replication starts) is carried out by DNA HELICASE.
However, due to the double-helical nature of the DNA, each strand is so tightly wound to each other. To prevent the strands from getting too tightly wound to each other as the DNA is unwinded, an enzyme called TOPOISOMERASE binds at a binding site close to the replication fork.
Hence, in the diagram, replication will not proceed if TOPOISOMERASE does not bind ahead of each advancing replication fork in region II because the DNA molecule will become super coiled and difficult to separate/unwind in order to continue replication.
DNA replication is the process in which DNA makes a copy of itself during cell division. The separation of two single strands of DNA creates a Y-shape fork and various enzymes play a crucial role in DNA replication.
DNA replication is a vital process in which parental genetic information is copied in the daughter cells before cell division.
The double-helical structure of the DNA is opened with the help of the enzyme DNA helicase.
Due to the double-helical structure of the DNA, each strand is tightly wounded. The strands after the replication bind with the enzyme topoisomerase, to close the replication fork.
The diagram shows replication, which will not proceed in region II because the DNA molecule will be super coiled and unwind it before the replication starts.

Carbon dioxide (CO2) is a greenhouse gas. It traps the heat in the atmosphere. Humans have used fossil fuels for only the last few hundred years. When burned, fossil fuels release CO2 into the atmosphere. Why do you think our fossil fuel use is a concern for environmental scientists?
Answer:
humans really heavily on fossil fuels, but unfortunately the more humans use it the more CO2 is being released,and the more greenhouse gases being trapped in our atmosphere, one of the reasons that are causing global warming
Explanation:
I think I could have done better but I cant find the right words to use (sorry)
Answer:
Burning fossil fuels increases the amount of CO2 in the atmosphere. A high level of CO2 throws the carbon cycle out of balance. With more CO2 in the atmosphere, the temperature on Earth increases.

Which of the following attributes of and organism cannot be seen by observing the organism?
A.phenotype
B.genotype
C.traits
The attribute of an organism that is not directly observable is the genotype. While phenotype and traits often manifest in observable ways, genotype refers to the genetic makeup, which requires specific tests to investigate.
Explanation:Out of the given options (phenotype, genotype, and traits), the attribute of an organism that cannot be observed just by looking at it is the genotype. Phenotype is the outward, physical manifestation of the organism. These include traits such as height, color, and shape which can definitely be seen by physical observation. Traits, generally speaking, refer to the individual characteristics of an organism, many of which can also be observed externally. On the other hand, genotype refers to the organism's entire set of genes, the sequences of DNA that code for specific traits, but are hidden within the cells, which can only be determined by genetic testing, not by simple observation.
