Identify the kind of response to the following argument: Argument: In nature, a species is more likely to survive when its weak members die out, so we should let the weak in our society die out. Response: In nature, a species is more likely to survive when it lives in its natural habitat, so we should live in our natural habitat. A. refutation by parallel reasoning B. refutation by reduction to absurdity C. refutation by counterexample D. not a refutation
Answer:
A. refutation by parallel reasoning
Explanation:
A refutation by parallel reasoning is an analogical inference between two arguments. This type of refutation occurs when an argument is invalidated by showing that the argument's conclusion is not supported by its premises, thereby the structure of the argument is incorrect. The parallel argument should demonstrate that the premises of the target argument are founded in a fallacy or don't provide a strong enough rationale to support/accept its conclusion.

A married couple plans to have children. The wife has blue eyes (a recessive trait) and her husband has brown eyes (a dominant trait). The husband’s mother had blue eyes. What percentage of their children could possibly have blue eyes?
Answer:
75%
Explanation:
The mom only carries the gene for blue eyes. The dad carries the gene for blue eyes, and the gene for brown eyes. So hypothetically speaking (because Punnet squares are only guesses/predictions) 75% of the kids could have blue eyes

How are photosynthesis and cellular respiration connected as a cycle?
Answer:
Photosynthesis is when energy, carbon dioxide and water react to produce glucose and oxygen. It is an endothermic reaction (takes in more energy than it gives off).
glucose + oxygen + (energy) → carbon dioxide + water
C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O
Respiration is the process of producing energy from glucose. It uses glucose and oxygen to give water, carbon dioxide and energy (thus making it exothermic).
carbon dioxide + water + energy → glucose + oxygen
6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2
As you can see from the equations, they are essentially the reverse of each other.
Another difference is how they are used. Respiration occurs in the mitochondria of all living cells, whereas only plants photosynthesize.
In plants, they make their own glucose using the sun's energy, then respire to allow them to use the glucose for the energy they can use. The glucose can also be stored and used in many other ways other than in respiration.
Suppose you are a politician representing the interest of a small community whose economic health depends on the fishing industry. How would you approach the problem of the overfishing of nearby species?
Answer:
To create more jobs in other fields.
Explanation:
As a politician, more jobs has to be created in other fields such as industries, education sector etc in order to avoid overfishing in the areas because the people related to fish industry will move to join other jobs that gives good pay as compared to fishing. If there are more jobs in other fields then more people will leave the fish industry and join jobs in other fields. In this way, we can avoid overfishing problems in the region that causes decrease in the population of fish species in water.

Which is used to make cell walls
Answer:

Figure 3 : Plant plasma membrane and cell-wall structure
A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein. These components are organized into three major layers: the primary cell wall, the middle lamella, and the secondary cell wall (not pictured). The cell wall surrounds the plasma membrane and provides the cell tensile strength and protection.

Figure Detail
Besides the presence of chloroplasts, another major difference between plant and animal cells is the presence of a cell wall. The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall. Plant cells have high concentrations of molecules dissolved in their cytoplasm, which causes water to come into the cell under normal conditions and makes the cell's central vacuole swell and press against the cell wall. With a healthy supply of water, turgor pressure keeps a plant from wilting. In drought, a plant may wilt, but its cell walls help maintain the structural integrity of its stems, leaves, and other structures, despite a shrinking, less turgid vacuole.
Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules. These fibers aggregate into bundles of about 40, which are called microfibrils. Microfibrils are embedded in a hydrated network of other polysaccharides. The cell wall is assembled in place. Precursor components are synthesized inside the cell and then assembled by enzymes associated with the cell membrane (Figure 3).
What Are Vacuoles?
Plant cells additionally possess large, fluid-filled vesicles called vacuoles within their cytoplasm. Vacuoles typically compose about 30 percent of a cell's volume, but they can fill as much as 90 percent of the intracellular space. Plant cells use vacuoles to adjust their size and turgor pressure. Vacuoles usually account for changes in cell size when the cytoplasmic volume stays constant.
Some vacuoles have specialized functions, and plant cells can have more than one type of vacuole. Vacuoles are related to lysosomes and share some functions with these structures; for instance, both contain degradative enzymes for breaking down macromolecules. Vacuoles can also serve as storage compartments for nutrients and metabolites. For instance, proteins are stored in the vacuoles of seeds, and rubber and opium are metabolites that are stored in plant vacuoles.
Conclusion
Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help reg

Describe the temperature, moisture and air pressure associated with a Continental Polar air mass.
Use this and the picture to help
Continental Polar Air Masses
cold temperatures and little moisture
Those who live in northern portions of the United States expect cold weather during the winter months. These conditions usually result from the invasion of cold arctic air masses that originate from the snow covered regions of northern Canada. Because of the long winter nights and strong radiational cooling found in these regions, the overlying air becomes very cold and very stable. The longer this process continues, the colder the developing air mass becomes, until changing weather patterns transport the arctic air mass southward.
Answer:
Continental polar has very low temperatures, little precipitation, and air pressure varies with the pressure system moving through
The variation in the US continental region is due to the change in the weather during the day and the night.
These are the reasons for the polar air mass:-

Can you determine the relationship between the risk of contracting Lyme disease and the concentration of ticks that act as vectors for the disease?
Answer: Since the vector transmitting the disease is the tick, the higher the density of ticks, the higher the rate of transmission of the disease.
Explanation:
Lyme disease is an infection caused by a spirochete-like bacterium of the Borrelia species and is transmitted by a vector, which is a living being (almost always an arthropod) capable of transmitting a disease to vertebrate hosts, including humans.
In this case, the disease is transmitted to humans through the bites of deer ticks that are infected with this bacterium. The ticks live in forests or grassland areas, woodlands and swamps near rivers, lakes or seas. Infections generally occur from late spring to early fall because infected deer ticks live in regions that have extreme temperatures (very low and very high) and high levels of humidity.
The first and most obvious symptom of Lyme disease is a localized rash that begins as a pink or red circle that expands over time and may appear 3 to 30 days after the bite. Although the disease can also affect the skin, nervous system, joints, muscles and heart.
Therefore, since the vector transmitting the disease is the tick (without ticks there is no transmission), the higher the density of ticks, the higher the rate of transmission of the disease.
What do you think accounts for the higher risk of earthquakes in Los Angeles than in Chicago?
Answer:
Los Angeles, California, rests on a major (and active) fault line known as the San Andreas Fault. It's the line between the Pacific and North American tectonic plates, and more seismic activity is measured daily than on the New Madrid Fault, which runs through New Madrid, Missouri, and around the mid-west. Chicago is still at risk, of course, but not nearly as much, given the small activity of the fault line.
The San Andreas Fault, a significant (and active) fault line, runs through Los Angeles, California.
Why is a higher risk of earthquakes in Los Angeles?There is more seismic activity recorded there every day than on the New Madrid Fault, which passes through New Madrid, Missouri, and other midwestern cities.
It is the boundary between the Pacific and North American tectonic plates. Chicago is still in danger, of course, but not nearly as much as before due to the fault line's low level of activity.
Therefore, movement along the San Andreas Fault and its numerous accompanying faults, which define the tectonic border between the Pacific and North American tectonic plates, is what causes earthquakes in California.

Base your answer to this question on the following information: You have isolated a primary signal factor from the blood of a space alien, which you name XFF (for X-files factor). You also have Isolated various types of alien cells which appear to Interact with XFF. Based on preliminar data, you think that XFF could be similar to one of three compounds normally found in human blood: epidermal growth factor (EGF), epinephrine, or estrogen. Which of the following would best be used to demorstrate XFF is most like EGF?
A. exposure of cells to tyrosine kinase inhibitors
B. microinjection into cells of nonhydrolyzable GTP analogues
C. exposure of cells to ryanodine
D. exposure of cells to radioactive XFF
E. receptor binding assays
Answer:
The correct answer is - A. exposure of cells to tyrosine kinase inhibitors.
Explanation:
EGF or epidermal growth factor is a protein compound found in human blood responsible for signaling is the member receptor tyrosine kinase family of proteins.
EGF signaling leads to activation or stimulation of various pathways such as Phosphatidylinositol 3-kinase, Ras and or Raf signaling, and or Akt signaling chain of reactions, or STAT pathway. By exposing the cells to the tyrosine kinase inhibitors leads to any of the given pathways then XFF is most likely similar to EGF.
