A prophage is a viral genome that infects bacterial cells, thus it integrates into a bacterial genome; while a provirus is a viral genome that integrates into an ekcaryotic genome.

If products do not decompose, ii will commonly dwell in landfills and so much area will be taken up. Biodegradable means that there is the abililty to be decomposed and there is no harm in the ecosystem produced by this process. Materials or objects can be broken down to smaller parts and absorbed into the soil that will serve as nutrients.

Larger DNA molecules travel more slowly across the gel matrix during electrophoresis than smaller ones do. As a result, the DNA molecules divide into different bands according to their respective sizes. The quantity of DNA that builds up in a band determines how black the band is.

Because DNA is negatively charged, it gravitates toward the positive electrode. All DNA fragments flow through the gel at the same speed because they all have the same mass-to-charge ratio.

A PCR result must frequently be further altered by cleavage with restriction enzymes. Without any DNA purification, restriction enzyme digestion may be carried out quickly and easily right in the PCR mixture.

The PCR primers' structure determines the size of the PCR result. To amplify an area of interest from a double-stranded DNA template, the user designs PCR primers. Always two primers are present, and they are made to border the area.

Explanation:

When a velocity's magnitude and direction do not alter over time, it is said to be constant.

Constant speed refers to a speed that remains constant throughout the duration of the motion. Constant speed is demonstrated in our example of using cruise control while driving a car.

When a velocity's magnitude and direction do not alter over time, it is said to be constant. In other words, this occurs when an object's rate of change in location remains constant throughout time.

An object is considered to be moving at a constant speed when it covers the same distance in the same amount of time. When moving at a constant place, an object covers a certain distance in a fixed amount of time. S = dt is a formula that can be used to express the speed.

The bloodstream receives oxygen from the lungs during gas exchange. Carbon dioxide leaves circulation enters the lungs. Between the alveoli and network of tiny blood arteries known as capillaries are the lungs.

The waste gas carbon dioxide is exchanged for oxygen at each cell in your body. This waste gas is then transported by your bloodstream back to your lungs, where it is expelled after being eliminated from the bloodstream. Gas exchange, a crucial activity carried out automatically by your lungs and respiratory system, is a fundamental function.

While carbon dioxide diffuses into the alveoli and is later breathed out of the body, oxygen diffuses from the alveoli into the capillaries, which carry it out of the lungs and to the rest of the body. The respiratory membrane serves as a barrier for the exchange of oxygen and carbon dioxide.

There are 2 main types of transportations through the cell membrane, in which both have the ability to utilize proteins to allow substances to enter and leave:

0. Active Transport

1. Passive Transport

Active transport must have ATP in order to allow the protein to be active for transportation. Passive transport doesn't need energy in order to transport a substance across the membrane.

Answer: Protein channels and carrier proteins.

Explanation:

The effects of the human population on Easter Island led to the ecocide hypothesis.

The island's carrying capacity for sustainable crops was exceeded by human populations, which led to a significant loss of forest cover. Its natural cycle of matter and energy likewise decreased or changed, and as a result, the population fought over the island's limited resources.

They turned to cannibalism since they were short on food and starving. In the years 1862 and 1863, blackbirds also plagued the island. The palm tree seeds are thought to have provided food for the growing rat population, according to archaeologists.

This theory was in line with discoveries made on other Polynesian islands. The rats and human activity would have eventually caused the tree population to dwindle. Hunt used the "rat plague" as the basis for his theory regarding Easter Island's deforestation.

Explanation:

Because the growth of the plant will take time leading into the future.

Kuru is a Transmissible spongiform encephalopathy which was formerly common among the Fore people of Papua New Guinea. This disease is caused by a prion, i.e., a protein that can trigger other proteins in the brain to fold abnormally. The abnormally folded proteins in the brain cause neurodegeneration which ultimately lead to death. The main symptom of the Kuru disease is the loss of coordination and control over the muscle movements. The transmission of Kuru was because of a ritual in which Fore people consumed body parts of their family members just after their death. The Fore people stopped to eat human meat in the early 1960s, causing the kuru epidemic to decline dramatically. It is not certainly known if the last kuru victim died in 2005 or 2009.

The correct answer is FALSE. Although Darwin, indeed recognized reproduction and competition as important drivers of global biodiversity, he did not included the role of inheritance. Rather, he emphasized the role of competition and natural selection.

The cell has several types of membrane transport alternatives, being the simple diffusion, facilitated diffusion, and active transport one of the options for the cell to exchange molecules between internal and external environment.

The types of cell transport:

1 - Simple Diffusion: is a process that does not need energy (passive), used to transport small and nonpolar molecules from a region of higher concentration into a region of lower concentration (in the gradient concentration direction);

2 - Facilitated Diffusion: is a process that does not need energy (passive), used to transport larger ions and polar molecules with the help of carrier proteins or pore proteins (transport proteins);

3 - Active Transport: There is two types of active transport, primary active transport is used for molecules moving against their gradient coupled to the hydrolysis of ATP, and secondary active transport is for molecules going with more molecules against their gradient. It is a process that needs energy (active) to happen, going always against the gradient of concentration of the cell.

The process is non-spontaneous and causes an increase in entropy.

The process is not automatic even thoug it involves transportation of materials in a cell. There is a change in the amount of free energy but there is entropy.

Plasma membrane it's located in the exterior of all cells.

The plasma membrane has several functions: first, it's the barrier between the interior of the cell and the rest of the environment; secondly, it protects the cell and gives it support; it also regulates what substances pass to the interior of the cell.

If the cell was a ballon, the plasma membrane would be the latex and all the air inside would be the cytoplasm.

Photosynthesis and cellular respiration are, in a way, opposite reactions.

While photosynthesis takes the light energy and water and converts carbon dioxide into glucose, cellular respiration takes the glucose to produce chemical energy and it results in carbon dioxide and water.

This means that both reactions involve glucose, carbon dioxide, and also water, so this would be the correct answer (A).

When we consider species like the ones the question tells us about, we usually one faces an example of predation, since squirrel can behave as tertiary consumers for spiders, which are then secondary consumers. So the roles they develop in the environment can be named as population maintenance (especially for the squirrels, because they can control the wolf spider population, and spiders can allow them to continue their population growth).

Protozoans like paramecium have protoplasmic invasions called gullets, which aid in these species' food uptake and digesting.

Protists have eukaryotic cells, as opposed to bacteria, these organisms feature cytoplasmic membrane-bound components as well as a nucleus that is membrane-bound.

Another kind of protists is zooflagellates, they resemble animals and use flagella to move. Flagella are whip-like organelles that rapidly spin and help an organism move through the water like a boat's propeller.

The majority of zooflagellates have one to eight flagella that aid in movement, protists do not belong to a monophyletic group of creatures.
