Monomers are small molecules that can be joined together to form larger molecules called polymers. In the analogy of beads on a string, monomers can be structurally similar or different, akin to various beads, and linked in many ways to create complex polymers.
In the analogy where monomers are being compared to beads in a necklace to describe polymers, monomers are the individual units that can be linked together in a chain to form a polymer. Monomers can be structurally similar or different and can be linked in various ways to produce complex polymers, analogous to how different colored beads can be strung together to create a multicolored necklace. Looking at the nature of monomers, we can deduce that monomers are indeed small molecules that are repeatedly connected by covalent bonds to form larger molecules, known as polymers. These monomers in a polymer could be of different types depending on the complexity and the function of the polymer formed.

Bradley decides one day to run a marathon without any training. After ten minutes has elapsed and Bradley has run half a mile, he begins to get cramps in his thighs. He is also breathing very rapidly. What is causing the cramps on Bradley's legs?
Answer:
The correct answer is "lactic fermentation".
Explanation:
Lactic fermentation is a type of anaerobic respiration that occurs in muscle cells as a way to produce energy when not enough oxygen reach the cells. This happens when a person is performing anaerobic exercise for a considerable period of time or without proper training, like Bradley that tried to run a marathon without any training. Lactic fermentation produces lactic acid build up on muscles, which is what is causing the cramps on Bradley's legs.

In a food chain, concentrations of harmful substances increase in higher trophic levels in a process known as
A. biological magnification.
B. genetic drift.
C. biological succession.
D. pesticide resistance.
The A. Biological magnification is the process which causes toxic substances to increase at each trophic level in a food chain, making apex consumers most at risk.
The term that describes the process whereby toxic substances increase along trophic levels of an ecosystem is biological magnification. This phenomenon occurs when synthetic chemicals, such as pesticides, become more concentrated as they move up the food chain, resulting in higher levels of toxicity for organisms at the top. For instance, when a marsh is sprayed with DDT to control mosquitoes, microscopic aquatic organisms like plankton absorb trace amounts of DDT.
Filter-feeders such as clams and some fish then ingest the plankton, accumulating DDT in higher concentrations. This process continues upwards through the food chain, with each trophic level experiencing a significant increase in the concentration of these harmful substances, often resulting in detrimental effects on apex consumers.

Mortality and emigration are the two factors that cause a decrease in population size.
Mortality is defined as the number of deaths in a population over time. When rates of mortality are high, population size might be reduced. Disease, accidents, and natural disasters are all common causes of death.
Emigration is a migration of people away from a country or region. When people emigrate, they are no longer considered a part of the population of the country or territory from where they departed. People may emigrate for a variety of reasons, including political instability, economic opportunities, and war.

Final answer:
A decrease in population size can result from economic and social crises that lead to lower birth rates, as well as high death rates due to health issues. Environmental factors, such as the availability of resources influenced by human activities, like the use of pesticides and habitat destruction, also affect population size.
Explanation:
Two factors that cause a decrease in population size include economic and social crisis, leading to reduced birth rates, and high death rates due to health issues and the collapse of social safety nets. For example, populations decline when birth rates drop during periods of economic hardship as individuals delay or forego having children. Additionally, a rise in mortality, due to factors like alcoholism or heart disease, can lead to a population decrease if the death rate surpasses the birth rate.
Another factor that can decrease population size is environmental resources, which are affected by human activities such as the use of pesticides and habitat destruction. A decline in available resources can lead to increased mortality rates and lower birth rates over time.

An increase in the number of brown bears in an Alaskan river ecosystem causes the ecosystem's carrying capacity for salmon to decrease. Which two terms describe the brown bear in this scenario? A.Parasite B.Biotic factor C.Limiting factor D.Primary consumer
Answer:
B and C, biotic factor and limiting factor
Explanation:
The carrying capacity of an ecosystem is the maximum number of organisms that an ecosystem can support based on the resources it contains.
The more the resources an ecosystem has, the more the number of organisms it can sustain and the higher the carrying capacity. On the other hand, the lower the resources an ecosystem has, the lower the number of organisms it can sustain and the lower the carrying capacity. These resources are often refers to as limiting factors.
Properly defined, limiting factors are those variables that act on a population and prevent it from increasing indefinitely. These variables can be density dependent or density independent.
Biotic factors are the living factors of the environment or an ecosystem that tend to interact with individuals living in such environment/ecosystem.
Hence, in this case, the brown bears can be viewed as a limiting factor since their increase in the river ecosystem decreased the ecosystem's carrying capacity for salmon. At the same time, they are part of the living components of the salmon's environment and can therefore be considered as a biotic factor.

The fossil record documents trends in which brains that are large relative to body size evolved in certain lineages, including hominins. in such lineages, what can you infer about the costs and benefits of large brains?
Final answer:
The evolution of large brains in hominins is attributed to their significant advantages in intelligence, social behavior, and adaptability, despite their metabolic costs. Enhanced cognitive abilities and improved diet through advanced tool use and meat consumption facilitated the sustaining of larger brain sizes.
Explanation:
When evaluating the evolution of large brains in hominins, it's essential to consider the costs and benefits. The fossil record indicates that large brains evolved in certain lineages, such as Homo, and are not merely a consequence of increased body size, but more likely related to complex behavioral adaptations. Large brains, while metabolically costly and demanding in early human development, provided significant evolutionary advantages such as enhanced cognitive abilities, improved social interactions, and advanced tool-making skills. The disproportionate energy use of the brain, requiring about 25-30% of human metabolic energy, points to the necessity of a high-quality diet, ultimately leading to a reduced gut size in hominins. The shift in diet, with an increased emphasis on meat, allowed for the nutrition necessary to sustain larger brains. Moreover, larger brains facilitated the development of material culture, complex social structures, and environmental adaptations. The evidence suggests that the benefits of a large brain, such as increased intelligence and social complexity, outweighed the energetic costs in evolutionary terms.
How does carbon’s high valence relate to its ability to form these large and complex biomolecules?

When a plant cell, such as one from a tulip leaf, is submerged in a hypertonic solution, what is likely to occur?
Submerging a plant cell in a hypertonic solution leads to water moving out of the cell, causing the cell to shrink in a process called plasmolysis. This consequently leads to loss of turgor pressure, resulting in the plant wilting.
Explanation:When a plant cell, such as one from a tulip leaf, is submerged in a hypertonic solution, the cell is surrounded by a solution with a higher concentration of solutes than within the cell itself. As a result, water molecules move out of the cell to balance the concentration, an occurrence known as osmosis. This outward movement of water causes the cell membrane to shrink and detach from the cell wall, a process termed as plasmolysis. Ultimately, the cell loses turgor pressure, which is the force of water against the cell wall that helps maintain the plant structure, leading to the plant wilting.
