Heyy.
So i did the alternative activity for this assignment.
In task one I only did part F:
answer:
Weathering damage on Cleopatra's Needle, an Egyptian obelisk in Central Park, New York City, is compared to known weathering rates of granites in various regions. The detrimental influence of the city's environment in 83 years of exposure has been attributed by textbook authors to damage to this coarse-grained foliated granite. As evidenced by the original depth of inscription in New York, about 11/2 inches of maximum surface reduction had occurred. Granite reduction rates in humid regions were calculated to be as low as 0.0076 mm per year, and even lower in deserts. The majority of the damage to the obelisk was caused by rising moisture laden with sulfate salts in Egypt, according to the findings. The hydration pressure of these salts, combined with frost wedging, is responsible for the major damage to the monument, which happened during its first few years in New York.
In task 2 I only did part D
answer:
Two independent sets of observations on sand activities in relation to the flowing river are recorded as the water passes through the meandering river. Stream abrasion can affect the morphology of a stream or river dramatically over time. Because the water can start erosion with anything near it, erosion can impact human communities near rivers.
MAKE SURE YOU SAY THAT YOU DID THE ALTERNATIVE ACTIVITY!!!!

The answer is d)
Explanation:
The cell will shrink because it is in a hypertonic solution.
This is because, in osmosis, water moves from a higher concentration to a lower concentration of water.
In this question, more water is present inside the cell as the percentage of NaCl (salt) is 0.9%. There is less water outside the cell as there is 1% of NaCl... So..the water will move outside the cell and the cell will shrink.
Also, the type of solution given is called a hypertonic solution.
Hypertonic solution: If the medium has a lower concentration of water than the cell, it is a hypertonic solution.

Since cuts from restriction enzymes occur in both dna backbones at different locations, the resulting dna fragments have unpaired regions called __.
Answers
Answer: Since cuts from restriction enzymes occur in both dna backbones at different locations, the resulting dna fragments have unpaired regions called overhangs
The cuts caused by restriction enzymes occur in different places in both DNA backbones; the resulting DNA fragments have unpaired regions known as overhangs.
What is recombinant DNA technology?In this technology, the modification of DNA is done by combining the original DNA with the desired gene. In gene editing, recombinant DNA technology is used. The most suitable organisms for this purpose are bacteria, yeasts, etc. They grow rapidly in a short period of time. As a result, they can provide desired products in a short period of time.
The desired gene is extracted and introduced into the bacteria using recombinant DNA technology. The DNA of bacteria is cut by restriction endonucleases. As a result of cutting, overhangs are produced.
The desired gene is taken and introduced to the bacteria's DNA. The bacteria transcribe and translate the target gene. An example is humulin. This process produces human insulin.
Hence, DNA fragments have unpaired regions called "overhangs."

What are cyclins, kinases, and telomeres? What do they do, and what are the differences between them? (Please explain, I’ll give brainliest!)
Answers
Answer:
Cyclins are the regulatory subunits of holoenzyme CDK complexes that control progression through cell-cycle checkpoints by phosphorylating and inactivating target substrates. Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks).
Kinases are a type of enzyme (a protein that speeds up chemical reactions in the body) that adds chemicals called phosphates to other molecules, such as sugars or proteins. This may cause other molecules in the cell to become either active or inactive. Kinases are a part of many cell processes.
Telomeres are DNA-protein structures that form protective caps at the end of eukaryotic chromosomes. They constitute the safeguards of chromosome degradation and are responsible for maintaining genomic integrity.
The key difference between cyclins and kinases is that cyclins are regulatory proteins that have no enzymatic function in the cell cycle, while kinases are catalytic proteins that have an enzymatic function in the cell cycle.

2. Describe the different ways that a system can be efficient. For example, time
efficiency, economic efficiency, and resource efficiency.
Answers
What Is Economic Efficiency?
Economic efficiency is when all goods and factors of production in an economy are distributed or allocated to their most valuable uses and waste is eliminated or minimized.
KEY TAKEAWAYS
Economic efficiency is when every scarce resource in an economy is used and distributed among producers and consumers in a way that produces the most economic output and benefit to consumers.
Economic efficiency can involve efficient production decisions within firms and industries, efficient consumption decisions by individual consumers, and efficient distribution of consumer and producer goods across individual consumers and firms.
Pareto efficiency is when every economic good is optimally allocated across production and consumption so that no change to the arrangement can be made to make anyone better off without making someone else worse off.
1:17
Economic Efficiency
Understanding Economic Efficiency
Economic efficiency implies an economic state in which every resource is optimally allocated to serve each individual or entity in the best way while minimizing waste and inefficiency. When an economy is economically efficient, any changes made to assist one entity would harm another. In terms of production, goods are produced at their lowest possible cost, as are the variable inputs of production.
Some terms that encompass phases of economic efficiency include allocative efficiency, productive efficiency, distributive efficiency, and Pareto efficiency. A state of economic efficiency is essentially theoretical; a limit that can be approached but never reached. Instead, economists look at the amount of loss, referred to as waste, between pure efficiency and reality to see how efficiently an economy functions.
Economic Efficiency and Scarcity
The principles of economic efficiency are based on the concept that resources are scarce. Therefore, there are not sufficient resources to ensure that all aspects of an economy function at their highest capacity at all times. Instead, scarce resources must be distributed to meet the needs of the economy in an ideal way while also limiting the amount of waste produced. The ideal state is related to the welfare of the population with peak efficiency also resulting in the highest level of welfare possible based on the resources available.
Efficiency in Production, Allocation, and Distribution
Productive firms seek to maximize their profits by bringing in the most revenue while minimizing costs. To do this, they choose the combination of inputs that minimize their costs while producing as much output as possible. By doing so, they operate efficiently; when all firms in the economy do so, it is known as productive efficiency.
Consumers, likewise, seek to maximize their well-being by consuming combinations of final consumer goods that produce the highest total satisfaction of their wants and needs at the lowest cost to them. The resulting consumer demand guides productive (through the laws of supply and demand) firms to produce the right quantities of consumer goods in the economy that will provide the highest consumer satisfaction relative to the costs of inputs. When economic resources are allocated across different firms and industries (each following the principle of productive efficiency) in a way that produces the right quantities of final consumer goods, this is called allocative efficiency.
Finally, because each individual values goods differently and according to the law of diminishing marginal utility, the distribution of final consumer goods in an economy are efficient or inefficient. Distributive efficiency is when the consumer goods in an economy are distributed so that each unit is consumed by the individual who values that unit most highly compared to all other individuals. Note that this type of efficiency assumes that the amount of value that individuals place on economic goods can be quantified and compared across individuals.
Economic Efficiency and Welfare
Measuring economic efficiency is often subjective, relying on assumptions about the social good, or welfare, created and how well that serves consumers. In this regard, welfare relates to the standard of living and relative comfort experienced by people within the economy. At peak economic efficiency (when the economy is at productive and allocative efficiency), the welfare of one cannot be improved without subsequently lowering the welfare of another. This point is called Pareto efficiency

The pyramid above illustrates the trophic levels in a typical forest or swamp ecosystem. In the soil, the organisms play a specialized role in the ecosystem. Select all of the statements that accurately describe the role of the soil organisms
Answers
Consumers of wetlands can include fish, birds, amphibians, mammals, freshwater and/or marine invertebrates (shrimp, clams), as well as fish. It is bacteria and fungi that decompose dead creatures in wetlands.
What trophic levels in a typical forest or swamp ecosystem?A form of wetland ecosystem where trees dominate the plant life and mineral soils have limited drainage. The latter distinguishes a swamp from a marsh, where grasses make up the majority of the plant life. Swamps can be found all over the planet.
Soil texture, water quality, and topography are examples of abiotic factors that are impacted by hydrology in a wetland, whereas plant and animal species, diversity, and abundance are examples of biotic elements that are influenced by hydrology in a wetland.
Primary consumers like mice devour those. Raccoons and other secondary consumers, like them, eat the mice. Then, apex predators like alligators devour raccoons.
Therefore, primary producers in the swamp, such as trees and grasses, are the first links in the food chain.
