Answer:
C. as nonspecific defenses, because they bar or stop infections without discriminating pathogens from other agents
Explanation:
The skin, tears and stomach acid are nonspecific defenses and they are some of the examples of the body's first line of defense. Nonspecific defenses are made up of interferons, chemical barriers (e.g. tears and stomach acid), inflammation and physical barrier (e.g. skin).
These nonspecific defenses defend the body from pathogens through their chemical contents in the body fluid or the tissue.
For example, Stomach acid is made of hydrochloric acid (HCl), HCl is potent enough to destroy pathogens that make its way into the stomach through food; this kind of barrier is a chemical barrier.
So also, the skin is a physical barrier which serve as a defense against pathogens.
Answer:
C. as nonspecific defenses, because they bar or stop infections without discriminating pathogens from other agents

What would happen if a dominant trait joined with the recessive trait? What is the end result? (Based off Gregor Mendel)
Answer:
When a dominant trait joins with the recessive trait, only the dominant trait will show when determining the organism's characteristics.
Explanation:
The dominant trait is "dominant" so it will mask the recessive trait. For example, brown eyes is a dominant trait for the color of someone's eye. Blue eyes is a recessive trait. If someone were to have both genes when they were born, they would have brown eyes because it masks the genes for blue eyes.

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"

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.

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.

Muscle cells in the human body can convert glucose into energy during moderate exercise. During intense exercise, however, the muscles become tired, lactic acid is produced, and pain can set in. Which statement best explains how muscle cell processes change as moderate exercise becomes more intense?
A. Oxygen becomes less available for respiration.
B. Carbon dioxide becomes more available for respiration.
C. Glucose is completely depleted during respiration.
D. ATP becomes depleted during respiration.
During the active and intense physical exercises, the speed of the glycolysis increases and lactate is produced. During an intense workout, the oxygen depletes.
What happens to the oxygen level?During the intense workout and exercise, the body muscles and cells cannot convert glucose molecules into energy and follow the pathway in the absence of oxygen resulting in the production of lactic acid.
Oxygen is the main input of the respiration process that becomes depleted and in the absence results in the formation of the lactic acid that provides muscle cells with the energy.
Therefore, option A. oxygen gets depleted and becomes less available for the respiratory process.
Learn more about lactic acid and oxygen here:
https://brainly.com/question/519398
Final answer:
As exercise intensity increases, oxygen becomes less available for aerobic respiration in muscle cells, prompting a shift to anaerobic metabolism, leading to lactic acid production and muscle fatigue.
Explanation:
The statement that best explains how muscle cell processes change as moderate exercise becomes more intense is: A. Oxygen becomes less available for respiration. During moderate exercise, muscles primarily use aerobic respiration to convert glucose into energy, utilizing oxygen to produce ATP, the energy currency of the cell. However, as exercise becomes more intense, the demand for ATP increases rapidly, outpacing the supply of oxygen. This leads to muscle cells relying more on anaerobic respiration, specifically glycolysis, which does not require oxygen but produces lactic acid as a byproduct. The accumulation of lactic acid contributes to muscle fatigue and can cause pain. Thus, the transition from moderate to intense exercise sees a shift from aerobic to anaerobic metabolism in muscle cells due to the reduced availability of oxygen.

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.

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.
