Answer:
The correct answer is -
II: lyse cells of interest, precipitate DNA
V. Digest (cut) genomic DNA with restriction enzyme
I. Digest (cut) phage (chromosome) with restriction enzyme so can ligate in the gene in next step!!
IV. Perform ligation (glue plasmid in!) reaction with genome fragments and phage.
III Introduce constructs via transformation into competent E. coli cells.
Explanation:
The total collection of the genomic DNA of an organism is known as the genomic library of the particular organism. In this library, the genomic DNA is inserted and stored in identical vectors.
The genomic library construction involved some major steps that are:
- Extract and purify DNA - lysing and separating the desired DNA of interest.
- Digest the DNA with a restriction enzyme - breaking or digesting DNA into fragments with restriction enzymes
- cut phage (chromosome) with restriction enzyme
- Insert the fragments of DNA into vectors
- introduce these recombinant a host bacterium by transformation, creating a DNA library.

Proteins on the surface of a human cell and on a bird influenza virus are represented in the diagram below. Describe a change in the bird influenza virus that would allow it to infect this human cell.
Answer:
Viral proteins can modify the most superficial portion in such a way that it is complementary to the receptor of the human cell.
Generally this happens due to a genetic recombination between an avian virus and a human virus within the respiratory epithelium of the pig: this process underlies the emergence of new, more virulent strains of the influenza virus and underlies the emergence of influenza pandemics

A researcher exposes a bacterial culture to UV radiation and then subjects it to progressively higher temperatures. As the temperature increases, the bacteria have a progressively harder time surviving. Analysis of the dead bacteria reveals large amounts of misfolded, aggregated proteins compared to wild-type control bacteria exposed to the same temperature increase. Which of the following is a plausible explanation for the data?
A. The ribosomes are mutated and are non-functional.
B. The initiator tRNA (fMet) has been mutated and is non-functional.
C. Molecular chaperones have been mutated.
D. DNA polymerase is mutated and non-functional.
Answer:
C. Molecular chaperones have been mutated.
Explanation:
In prokaryotes; transcription and translation occur consecutively. Protein doubling additionally happens following the translation. The heat stun proteins or molecular chaperones are imperative to assume a part in the appropriate collapsing of the protein. At high-ranging temperatures, the protein misfolding can be ascribed to a change in mutation of the molecular chaperones.

Describe three ways in which economies are
likely to be affected by climate change
Answer:
1. Climate change affect the geography within which economy of the world operate
2. It changes the comfortability of human within the global industry
3. Growth Zone is affected
Explanation:
1. Climate change affect the geography within which economy of the world operate: economic of the world are affected by change in climatic condition in the since that there is shift in the usual period of seasons. For example, taken Nigeria as a region in West Africa, rainfall is expected to start around March in almost all part of the country, however, due to climate change, some part don't still have rain till May. This causes a shift in farmers plan and affect the supply of farm produce to the local market and to the global market, in turn affecting the gross domestic product of the country.
2. It changes the comfortability of human within the global industry. Take for example, fossil fuel, it is part of human being to address some unfavourable conditions among which is climate change which causes global warming, during this period, the way industries and people uses fossil fuel are been changed and it have direct effect to global economy.
3. Growth Zone is affected: change in climatic condition changes world economy growth zones. Thus could be seen in transportation sector, when the water level is affected, international movement of cargoes by ship are affect and hence, some trades agreements are altered thereby changing the growth zone.

A fungus decomposes dead organic matter.A fungus decomposes dead organic matter. A tree absorbs inorganic nutrients from the soil.A tree absorbs inorganic nutrients from the soil.
Answer:
- A deer eats the leaves of a tree.
- A snail eats a clam
Explanation:
Predation is one of the mode of feedings used by certain organisms. It is a relationship between two organisms in which one of the organisms called PREDATOR kills/harms and feed on the other organism called PREY.
According to this question, the two examples that represent predation are as follows:
- A deer eats the leaves of a tree; the deer, which is the PREDATOR feeds on a tree plant, which is the PREY.
- A snail eats a clam; the snail is the PREDATOR in this case and it harms the clam (PREY) by killing and feeding on it.

A drought decreases the water level in Lake Winnipeg. The carrying capacity of the lake decreases.
Limiting factor?
Explain
Answer:
Water, fish
Explanation:
The limiting factors are the water of course and the organisms living in the lake.
A drought decreases the water level in Lake Winnipeg and the carrying capacity of the lake decreases. This is because it is:
Density IndependentWhen something is said to be density Independent with respect to ecology, it means that an external force is able to influence the volume of a habitat, notwithstanding the density.
As a result of this, this particular principle is in place here as a drought which is an external factor is able to affect the size of the water.

Why do large islands usually have more species than smaller islands?
Answer: Reason Why
Explanation: A bigger target is easier to hit than a small one, and a big island is more likely to have species land on it by chance than a small one is. Larger islands have more space than smaller islands, so there are likely to be more resources available for species to use. The opposite is true for smaller islands.

A salt marsh community includes egrets, gulls, and marsh crabs living together in a salt marsh. What does one female egret represent?
Answer:
It is a tool for keeping population in equilibrium state.
Explanation:
One female egret represents that she is a tool for the continuity of its breed or species because female egret lays eggs and reared their offspring in order to maintain its generation in that salt marsh area. These female egrets are the essential part of this salt marsh ecosystem due to the ability to control the population of other organisms through feeding behaviour. These female egrets helps in maintaining the equilibrium of the ecosystem by constantly producing baby egrets.

The function of the hepatic portal circulation is to ________. The function of the hepatic portal circulation is to ________. return glucose to the general circulation when blood sugar is low carry toxins to the kidney for disposal through the urinary tract distribute hormones throughout the body collect absorbed nutrients for metabolic processing in the liver
Answer:
The correct answer is ''collect absorbed nutrients for metabolic processing in the liver.''
Explanation:
Portal circulation is called that system that is between two large capillary beds, represented by the gastrointestinal organs, pancreas and spleen on the one hand, and the liver on the other. Hence, any venous system of the organism that is located between two capillary territories is called "portal system".The hepatic portal vein collects the deoxygenated blood from the gastrointestinal system, spleen and pancreas, this blood is venous and comes deoxygenated, in addition to being loaded with the nutrients absorbed in the digestive process, so it is a blood subjected to a high overload, but that quickly, thanks to its distribution through the liver, it will be bypassed to various chemical processes to extract a large part of the nutrients from it, and purify and eliminate toxins.
The function of the hepatic portal circulation is to collect absorbed nutrients for metabolic processing in the liver. Therefore, option D is correct.
The hepatic portal system is also known as the hepatic portal circulation or portal venous system. It is a specialized network of blood vessels that carries blood from the gastrointestinal tract, spleen, and pancreas to the liver. It plays a crucial role in directing nutrient-rich blood from the digestive organs to the liver for processing, storage, and detoxification before it is distributed throughout the rest of the body.
The hepatic portal system allows the liver to regulate the composition of blood coming from the digestive organs before it enters general circulation. Thus, option D is correct.
