When a virus infects a cell, sometimes it remains dormant while the cell replicates, allowing its dna to be copied into each new cell before activating and producing virus copies. this is the ___________ cycle?

Answers

Answer 1
When a virus infects a cell, sometimes it remains dormant while the cell replicates, allowing its DNA to be copied into each new cell before activating and producing virus copies. This is the lytic cycle. This cycle may result to the destruction of the infected cell and its membrane. The virus that enters the cell will take over its replication mechanism, makes virus infected DNA and virus infected proteins, and then lyses will break open the cells. It will allow the newly produced viruses to leave the cell that is being disintegrated already in order to infect other cells. This cycle is the most common method of viral replication.

During a rainy spring, where are you most likely to find surface runoff? PLEASE HELP

A. In a grassy prairie

B. On a mulched flowerbed

C. On a sloped parking lot

D. In a sand pit

Answers

Answer: C. On a sloped parking lot

Surface runoff can be referred as the flow of water, that occurs when the excess water flows from the storm water, melt water, flood, rain streams and rain fall. The fast moving water current takes along with it superficial layers like surface and sub- surface layers of soil. Hence, causes water erosion of soil.

The slope parking lot will favor, surface runoff more likely than in a grassy prairie, mulched flower bed, or in a sand pit because the slope will provide a surface for free flow of water. There are chances that water gets absorbed by the soil in the grassy prairie, mulched flower bed and sand pit. Whereas the slopy surface of parking lot will not allow the water retention by soil, instead will accelerate the flow of water.

Which carbohydrate can be used by the body as an immediate source of energy? glucose
cellulose
chitin
glycogen

Answers

Glucose is an important energy source of the body. It can be rapidly used as a fuel for the energy needs of the body or can be stored as glycogen in the liver and muscle cells.

Further Explanation:

Carbohydrates are macromolecules which are composed of atoms of hydrogen, carbon, and oxygen. The carbohydrates are used as a fuel to perform normal body functions. They are categorized as monosaccharides, oligosaccharides, disaccharides, and polysaccharides.

The monosaccharides are simple sugars namely fructose, galactose, and glucose. These monosaccharides have a similar molecular formula  [tex]\textbf{C}_{6}\textbf{H}_{12}\textbf{O}_{6}[/tex] but show different arrangements of atoms in their structural formula. The disaccharides are made when two simple sugars are linked together. For example, glucose and fructose are linked or bonded together to form sucrose. The molecules containing three to six monosaccharide units form the oligosaccharides.

The polysaccharides are complex molecules consisting of monosaccharide units in large numbers. For example, cellulose is a vital structural constituent in plants and is comprised of many glucose units. Starch and glycogen are found respectively in plants and animals as an energy source. They are long-chain branching polymers of glucose. Chitin is also a fibrous component present in the cell walls of fungi. It is a polymer of a glucose derivative which is N-acetylglucosamine.

In order to use energy stored in glycogen, cellulose, and chitin, they have to be broken down into simple molecules or monosaccharides (glucose). This glucose is then utilized during cellular respiration to form ATP (adenosine 5' triphosphate).

What is the objective lens used to locate the specimen and first focus?

Answers

Course alteration is the first to be utilized to find the example, and just with the low power objective. When seeing an example, you should dependably utilize the lower control target focal points first. Low power focal point gives the most stretched out field of view and makes it less demanding to discover the example when you look through the magnifying lens. Finding the example at high power, without first focusing it in the field of view at low power, is almost outlandish.

The objective lens of a microscope is used to locate the specimen and achieve initial focus. With magnification values typically from 5x to 100x, these lenses are parfocal, allowing for easy magnification changes while keeping the sample in focus.

The objective lens on a microscope is the lower lens used to locate the specimen and first focus on it. In a typical microscope setup, there are typically multiple objective lenses with magnification values ranging from 5x to 100x, which are mounted on a rotating turret that allows for changes in magnification. These objectives are generally parfocal, meaning they are designed so that the sample remains in focus when switching between different magnification objectives. The combination of the objective lens and the eyepiece or ocular lens enables the microscope to magnify small objects, where the objective lens plays a crucial role in establishing magnification and initial focus.

To properly view a sample, optimal illumination is necessary. The light source should be centered on the specimen, with parallel light rays focused by the condenser lens system. The condenser can be moved up and down to adjust focus, and the condenser diaphragm regulates the amount of light suitable to the size of the objective lens. To focus on the sample when using higher magnifications, an increased amount of light is needed.

Overall, the objective lens is instrumental in the first step of magnification and focusing, and when used in conjunction with the ocular lenses inside the eyepiece, it allows for detailed examination of microscopic samples.

What process can be described as two cell divisions genetic variation and haploid cells

Answers

Meiosis can be described as two cell divisions genetic variation and haploid cells. 

The right answer is meiosis.

Meiosis is the process of double cell division allowing the formation of gametes, or sexual cells in eukaryotic organisms. It differs from mitosis, somatic cell division, which takes place only in a time. From a diploid mother cell, we obtain four haploid daughter cells with different genetic material.

* A first division of meiosis: the reduction division.

* A second division of meiosis: the equational division.

This process generates genetic diversity. It leads to the formation of haploid cells, designed to fuse with others, so as to obtain diploid cells after fertilization.

A scientist has been tracking and studying a population of deer in Yellowstone National Park. He surveys the population every six months. Usually, the population is thriving and has a gene pool with a wide variety of traits. But during one six-month period, an event occurred that affected the population, and when the scientist returned, the amount of genetic variation had decreased significantly. Which of the following is most likely the event that occurred to change the population? Yellowstone National Park expanded its borders. A population of wolves was introduced into Yellowstone National Park. The amount of disease in the deer population decreased. More grass and shrubs were planted in Yellowstone National Park.

Answers

Answer: A population of wolves was introduced into Yellowstone National Park.

Explanation: The following should be the answer because all of the other options would be beneficial to the deer population and therefore the gene pool would not be affected. However, these new wolves that were introduced would most likely prey on the deer and hence decrease the existing gene pool which in turn affected the genetic variation of the deer population.
The answer would be B) A wolf pack has been introduced into the population. This is because of the following:

-If a population increases, the gene pool increases; if it decreases, gene pool decreases
-If Yellowstone expanded their borders, that would give the deer more room, but not necessarily increase, or decrease the population.
-If the amount of disease were to decrease, then the population would grow.
-If more grassland and shrubs are planted, the deer would have an abundance of food, and the population would increase.

The only logical answer is the wolves, because the wolves would consume the deer as a food source, causing the population to drop, and subsequently,

When an athlete first starts to exercise, her initial energy needs are provided primarily by the aerobic energy system?

Answers

I think the statement above is false. When an athlete first starts to exercise, her initial energy needs are not provided primarily by the aerobic energy system rather is provided by the anaerobic energy system. As the physical activity starts, there is only a small amount of energy supply that is present in the muscles for use immediately and the usage of such energy does not require any oxygen. As the energy in the muscles depletes, that is when the aerobic energy system would take into action where carbohydrates are being used up and being reacted with oxygen so as to produce energy to be used by the muscles.
