Answer:

Lysogenic replication cycle is one unique process in T7 virus replication.

Explanation:

The T7 virus is a virus that attacks bacteria ( bacteriophage). Unlike other viruses (plants and animals viruses), it replicates within the host cell by means of two cycles: the lytic replication cycle and the lysogenic replication cycle.

Virulent phages replicate through the lytic replication cell and this lead to the death of the cell through cell lysis.

The lysogenic replication cycle involves bacteriophages known as temperate bacteriophages. Temperate bacteriophages can become part of a host chromosome forming a prophage. The prophage replicates with the formation of daughter cells with incorporated viral genetic materials until when induced to enter into the lytic stage thereby producing new viruses which then exit the host cell by cell lysis.

This process of incorporation into the host cell genome is known as lysogenic replication and is unique to the bacteriophages.

Viruses are neither living nor dead organisms. The viruses require a host to replicate. The virus follows the lysogenic or lytic cycle to replicate. The T7 virus follows the lysogenic replication pathway.

The T7 virus follows the lysogenic pathway, in which the nucleic acid of the bacteriophage is incorporated into the host genome. The T7 virus intervenes on the bacteriophage genome.

In the lysogenic cycle, bacteriophages can become part of the host genome. This genome is then known as prophage. Prophage replicates and forms the daughter cells with the altered genetic material of the host.

The new cells produced are released by the lytic cycle, in which the cell produces new cells by lysis.

Thus, the incorporation of the host cell genome in the bacteriophage via the lysogenic cycle is a unique feature of a virus, T7.

The answer is a) enzymes

Answer:

An active site contains a binding site that binds the substrate and orients it for

catalysis. The orientation of the substrate and the close proximity between it and

the active site is so important that in some cases the enzyme can still function

properly even though all other parts are mutated and lose function.

Answer:

This is due to bio magnification.

Explanation:

When there is a gradual increase in concentration toxins(pesticides) in the tissues of organisms progressively in the food chain,the term for describing this is called -bio magnification.

The progressive multiplication in the concentration of these toxins may be due to  non-biodegradable nature of the toxins,which are absorbed into the tissues of mostly the producers from the environment faster than they could metabolized by the body.

.Therefore these could not be removed by the producers, during excretion and respiration,and hence build up progressively upwards in the consumers.

Answer:

F. Is fatty acid molecule.

Explanation:

It's unsaturated fatty acid.

Fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end.

It is that carboxyl group that makes it an acid (carboxylic acid).

Dear Mrs. Been.

In view of the importance that you have in our educational environment in relation to the position of headmaster that you occupy, I would like to emphasize the importance of classes with moral lessons, in the hope that you will authorize and encourage this type of lesson in our school.

The most important positive point of adopting this type of lesson is to teach students to distinguish correct and incorrect elements, about behaviors and concepts. This will allow for the formation of conscious adults with great rational capacity.

Another positive point is the ability to encourage students to solve ethical and moral problems that develop from a non-linear point of view, as most problems in the real world present themselves. By seeing and solving these problems in the school environment, students will be better prepared for the future that awaits them.

Last but not least, I would like to point out that students who have well-stimulated and trained moral concepts are better able to promote not only personal benefits, but also social, political and economic benefits for the communities in which they operate.

I look forward to your comments on this suggestion.

Kind regards,

Mary Lang

Dear Mr Peter,

Education is important to the growth and the development of the country and and since you play a vital role as a leader in this educational institution, I'll like to emphasize the importance of moral lessons to the students.

Moral lessons are important as they help in shaping the future of the students. When students are taught moral lessons, they will have good behaviors which will be vital to the nation.

Moral lessons can also enable the students know the difference between the rights and the wrongs on the society and enable them to be better citizens in the society.

Lastly, moral lessons can help in the promotion of peace and unity. When the students have good behaviors, they look out for each other and see always willing to help one another. This helps in promoting unity and peace in the school and the society at large.

In conclusion, I'll be glad if my letter is given a positive reply and moral lessons are instilled into the students.

Yours faithfully,

John.

Answer:

Does the movement of molecules stop when the concentration of a solute is equal on both sides of a membrane?

The concentration of solute molecules on both sides of the membrane will vary over time, and the solute molecules will continue to pass through the membrane even when the concentration gradient is reversed.

The environment in and around the cell is constantly. The diagram shows a cell with a higher concentration of solute molecules on the inside than on the outside. This means that there is a concentration gradient, and the solute molecules will tend to move from the inside of the cell to the outside. This process is called diffusion.

The solute molecules can also move through the membrane by other mechanisms, such as facilitated diffusion and active transport. Facilitated diffusion is a process that uses proteins in the membrane to help the solute molecules move across the membrane. Active transport is a process that requires energy to move the solute molecules across the membrane.

The concentration of solute molecules on both sides of the membrane will continue to change over time. As the solute molecules move from the inside of the cell to the outside, the concentration of solute molecules on the inside of the cell will decrease. This will create a new concentration gradient, and the solute molecules will continue to move from the inside of the cell to the outside.

Answer:

1.) A and D

2.) B

Explanation:

The power he used to move the boxes can be found by determining the rate at which work was done on the boxes. The power of light Chad turned on is the amount of energy transferred per time. So the correct options are A and D. In 2nd, the power used was 6.25 J/s. So the correct option is B.

The watt, denoted by the letter W, is the common unit used to measure power. James Watt, a Scottish businessman and inventor, is honoured with the unit's name. The watt is certainly a term you frequently encounter in daily life. Electrical devices like light bulbs and stereos commonly advertise their power output in watts. One watt is equivalent to one joule of work performed each second by definition.

​Horsepower is another power unit that is still extensively used. This was first used to describe the ability of a regular horse to spin a capstan in the 17th century and is often represented by the sign hp. Since then, a metric horsepower has been defined as the force needed to raise a 75 kg mass a metre in one second, where 75 kg is the mass's weight in kilogrammes.

Therefore, for 1) the correct option is A and D and for 2) the correct option is B.

The answer is A mitosis allows for reproduction. This is because during mitosis two identical daughter cells are created which can contribute to an embryo.

Hope this helps ! <3

It is important for cells of multicellular organisms to undergo mitosis because mitosis produces cells that are identical to the original dividing cell. Thus, the right option would be D.

Mitosis involves the division of vegetative cells and it results in daughter cells with the same morphology and genome as the parent cell.

The division of vegetative cells in multicellular organisms will ensure that damaged or dead cells are replaced with cells of similar morphology and genome.

Apart from replacing dead or damaged cells, mitosis also allows multicellular to grow in size by allowing similar cells to spring from existing cells.
