Answers

Answer:

Amount of water is constant

Reaction Rate is variable

Temperature is variable

Initial amount of tablet is constant

Particle size is constant

Explanation:

The first part of the lab procedure focused on temperature. There were several factors, and we are classifying each of the factors as variable or constant.

What are variable and constant parameters ?

The variable parameters are those quantities that are not fixed in the experiment but are constantly changing in the course of the experiment with time.

The constant parameters are those quantities or variables that are fixed and posses a same value in the course of the experiment with the change in time.

Labelling the factors given as variable or constant -

Amount of water is constant.

Reaction Rate is variable.

Temperature is variable.

Initial amount of tablet is constant.

Particle size is constant.

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.

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

How would larger substances like proteins get into or out of the cell membrane?

Answers

Answer:

It is possible for large molecules to join a cell by a method called endocytosis, where a small piece of the cell membrane surrounds the particle and is brought into the cell. If the particle is solid, endocytosis is also dubbed phagocytosis. If fluid droplets are taken in, the process is called pinocytosis.

Just look at the picture :)

Answers

Answer:

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.

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.

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."
