Answer:

B

Explanation:

Answer:

C) Water will flow more freely across the semi-permeable membrane.

Explanation:

Osmosis is the net movement of water molecules from an area of higher water concentration to that of lower water concentration.

Here in this case, an external pressure is applied to the solution with higher 'solute' concentration. If the pressure applied is greater than the osmotic pressure then the direction of water flow through the membrane would be reversed. Therefore, water molecules will flow from the high solute concentration to lower solute concentration.

The option C is the correct option.

Which is water will flow more freely across the semi-permeable membrane.

an increase in temperature can increase enzyme activity (but not too high) and a cooler temperature decreases activity, an effect on Ph and this is not so much environment but how many enzymes there are in total

Changes in temperature, pH levels, and substrate concentration can significantly affect the activity of enzymes.

Enzymes are highly sensitive to their environment. Temperature alterations can either increase or decrease enzyme activity. Most enzymes work optimally within a specific temperature range, and deviations from this range can denature or slow down their activity. Similarly, changes in pH levels can alter the ionization of amino acids within the enzyme's active site, affecting its ability to bind with substrates. Enzymes have specific pH optima, and deviations from this optimum can lead to reduced activity.

Substrate concentration impacts enzyme activity. As substrate concentration increases, the rate of enzyme-catalyzed reactions generally rises, but this increase is limited by factors such as the enzyme's saturation point. These environmental factors play crucial roles in regulating enzymatic reactions, making enzymes highly adaptable to different cellular conditions.

Two electrons completely fill its outermost electron shell

A helium atom is more stable than a hydrogen atom due to its stronger nuclear force complete first electron shell and valence shell configuration.

A helium atom is more stable than a hydrogen atom for several reasons. Firstly, a helium atom has two protons in its nucleus, while a hydrogen atom has only one. The additional proton in the helium atom contributes to a stronger nuclear force making the helium atom more stable. Secondly, the helium atom has two electrons which fill its first electron shell completely resulting in a stable configuration.

On the other hand a hydrogen atom has one electron meaning its first electron shell is not completely filled, making it less stable than helium. Lastly the valence shell of helium contains two electrons which provides it with stability as it already satisfies the octet rule. Conversely hydrogen's valence shell contains only one electron making it more likely to react with other atoms to achieve stability.

the cell goes into osmosis and goes into hypnotic solution

Answer:

The correct answer is cell will burst.

Explanation:

When a cell takes up water from the environment it will swell up and will become flaccid. This usually happens when a cell is placed in the hypotonic solution with a high concentration of water outside and low solute and the water will move into the cell through osmosis.

If the excess water is not removed from the cell the cell will burst or lyse.

Thus, the cell will burst is the correct answer.

1. Answer: 900x

A typical microscope has two lens: ocular lens which located near the eye, and objective lens which located near the object. The image will undergo magnification of both lens. The total magnification of the object would be the product of both lens multiplication, not the sum. The multiplication will be: 20x * 45x= 900x

total mag= ocular * object

total mag= 20x * 45x

total mag= 900x

2.  Answer: 100x

The total magnification of the object would be the product of both lens multiplication. If the total magnification 1000x, that mean it was the product of ocular lens and objective lens. If ocular lens magnification is 10x, objective lens magnification would be:

total mag= ocular * object

1000x= 10x*object

object=1000x/ 10x=

object=100x

3. Answer: 0.2 mm

The area of the microscope that can be viewed by the eye should be the same. But since the magnification is different, the actual area that it represent will be different. Microscope with bigger magnification will have smaller diameter of the field of view(DFV).  Remember that micrometer(μm) is 1/1000 of millimeter(mm). The DFV would be:500 μm/ ( 1000x/400x)= 200μm= 0.2 mm

4. Answer: 750μm

This question is similar to number 3 question. Remember that 1 millimeter(mm) equal to 1000 micrometer(μm) .

The DFV of a 10x objective lens is 3 mm. Then the DFV of 40x lens would be:

DFV2= DFV1/ (mag1/mag2)

DFV2= 3mm/ ( 40x/10x)= 0.75 mm= 750μm

5. Answer: 125μm x 37.5μm

The lens DFV of microscope from question 4 is 750μm, so the width and length of the area would be 750μm.

If 6 organisms could fit across the DFV if they were laid end-to-end, the length would be: 750μm/ 6 organism= 125μm

If 20 organism could fit is stacked side by-side, then the width would be: 750μm/ 20 organism= 37.5μm

6. Answer: 6mm

This question is similar to number 3 and number 4 question. Remember that 1 millimeter(mm) equal to 1000 micrometer(μm).

The DFV of a 100x objective lens is 1.5 mm. Then the DFV of 25x lens would be:

DFV2= DFV1/ (mag1/mag2)

DFV2= 1.5mm/ (100x/25x)= 6 mm

7.Using the 100x objective lens from question 6, you estimate 12 organisms could fit across the DFV if they were laid end-to-end and 30 could fit is stacked side-by-side. What is the length and width of this organism (in microns)?  

Answer: 0.5mm x 0.2mm or 500μm x 200μm

The lens DFV of microscope from question 6 is 6 mm, so the width and length of the area would be 6 mm.

If 12 organisms could fit across the DFV if they were laid end-to-end, the length would be: 6mm/ 12 organism=0.5mm

If 30 organism could fit is stacked side by-side, then the width would be: 6mm/ 30 organism= 0.2mm

The magnification of microscopy is given by the product of the ocular and objective lens magnification. Diameter of Field of View (DFV) changes inversely with the magnification. The size of an organism is estimated by dividing the DFV by the number of organisms that fit across the view.

In microscopy, the total magnification is obtained by multiplying the magnification of the ocular lens and the objective lens.

1. For an ocular lens with magnification 20x and an objective lens with magnification 45x, the total magnification is 20x*45x = 900x.

2. If the total magnification is 1000x and the ocular lens magnification is 10x, the objective lens magnification is 1000x/10x = 100x.

3. DFV decreases with increasing magnification. If the DFV at 400x is 500 μ, then at 1000x, the DFV would be (500 μ * 400x) / 1000x = 200 μ or 0.2 mm.

4. If the DFV at 10x is 3 mm, then at 40x, the DFV would be (3 mm * 10x) / 40x = 750 μ.

5. If 6 organisms fit across the DFV end-to-end at 40x (750 μ), each organism's length is 750 μ / 6 = 125 μ. If 20 organisms fit side by side, each organism's width is 750 μ / 20 = 37.5 μ.

6. If the DFV at 100x is 1.5 mm, then at 25x, the DFV would be (1.5 mm * 100x) / 25x = 6 mm.

Proteins

Explanation:

Proteins perform several functions such as regulation of cellular processes and transport of materials in and out of the cells.

Some proteins serve as enzymes and catalyze the cellular processes and thereby regulate the rate of the product formation. Proteins such as transcription factors regulate the expression of several genes. Some hormones are proteins or derived proteins. Insulin is an example which in turn regulates the blood glucose levels in the body.  

Some of the proteins present in the cell membrane serve as channels and pumps to allow the transport of various substances across the cell membrane.  

Option C) A line graph is the best option for illustrating the relationship between two variables that are changing, such as displaying economic trends over time.

When it comes to showing a relationship between two variables, a line graph is often the most effective graph to use. This type of graph is particularly useful for illustrating how two variables change in relation to each other. For instance, when tracking economic data such as the unemployment rate over time, a line graph can clearly display the trends and patterns.

In comparison, other types of graphs like a pie graph or bar graph, serve different purposes. A pie graph is best suited for showing how a whole is divided into parts, indicating percentages or proportions. Meanwhile, a bar graph is useful when you want to compare different groups or categories, where the height of each bar reflects a particular value.

Therefore, the correct answer is option C) line graph.

The density dependent factors are factors whose effects on the size or growth of the population vary with the population density. There are many types of density dependent dependent factors such as; availability of food, predation, disease, and migration. However the main factor is the availability of food.

Decrease in rabbit population can be caused by extreme weather conditions or natural disasters increased predation and decrease in available food resources.

There are various factors that can lead to a decrease in the rabbit population. Firstly weather conditions and natural disasters can negatively impact the rabbit population as extreme cold forest fires or floods can lead to mortality regardless of population density. Secondly an increase in predation can lead to a decrease as well. For example if the population of a predator like wolves or coyotes increases it could lead to more rabbits being hunted and thus a decrease in their population. Lastly a decrease in available food resources can also cause the population to decrease as it leads to less successful development and reproduction in rabbits.

The Answer is A on edugenity

The study of artificial selection by Darwin helped him to establish his theory of evolution via natural selection. One of the animals Darwin examined in detail was the domestic rock pigeon. In the 1850s breeding of pigeons was an ancient past time, thus, Darwin decided to keep and breed the pigeons by himself.  

While studying pigeons, Darwin established scrupulous determinations of their skeletons and wondered at the breeds' distinct colors, behaviors, and proportions. He also observed the patterns of inheritance of various features, and he demonstrated that birds of very distinct breeds can, however, generate fertile offspring. Thus, supporting the theory that they all originated from a single species.  

Answer:

Answer for PLATO is ; Darwin concluded that if traits in captive pigeons could be selectively passed on to offspring, the selection of traits could also happen in nature.

Endotherms and Ectotherms. Humans, along with all other birds and mammals are endotherms, which means that they are animals that actively maintain a stable body temperature by generating heat. People sometimes call endotherms warm-blooded animals

Answer: Endotherms and ectoderms

Explanation:

Mammals  like human beings, and many more animals, are endotherms can actively maintain their body temperature by the help of the process known as homeostasis by generating heat.

Such kind of animals are known as endotherms because they can regulate their body temperature.

The reptiles, birds and insects cannot maintain their body temperature so they are known as ectoderms. They are commonly known as cold blooded animals.

A cell membrane protects a cell from it's surroundings. The cell membrane controls the movement of substances from the outside and inside of cells and organelles.

The cell membrane, also known as the plasma membrane, is the outer covering of animal cells which sits inside the cell wall of plant cells. It is semi-permeable so it allows certain materials to go in and out of the cell. Substances that can pass easily in and out of the cells include oxygen, carbon dioxide, and water. So basically, it is separates the cytoplasm from the outside environment, allowing only certain molecules to enter and exit the cell and also controls the amount of the substances that can go in and out.

Fever is a state of body in which body temperature is above the normal temperature ( 37 °C).

Due to elevated temperature germs cannot colonize, reproduce and spread disease because their optimum temperature ( 37 °C) is not available due to fever.

Answer:

Every cell requires a particular temperature to grow, even the bacterial cell requires optimum temperature to grow to cause infection inside the human body.

The normal body temperature allows many bacteria to grow inside the body causing infection. But during the time of fever there is a slight elevation in the temperature of the body.

This elevated temperature does not allows the growth of certain bacteria causing infection.This is how fever prevents infection.

Pandas are an endangered species that primarily eat bamboo for energy. They digest bamboo with the help of microbes in their gut, and research into these microbes may contribute to advances in biofuel technology.

Pandas are an endangered animal that eats bamboo and are known for their peaceful and sympathetic demeanor. They obtain their energy by consuming bamboo, relying on a diverse population of symbiotic microbes within their digestive tracts to break down the cellulose, as they do not produce their own cellulase enzymes. This attribute has piqued the interest of researchers like Dr. Ashli Brown at Tennessee State, who found over forty cellulose-digesting bacteria in panda feces. This discovery could have significant implications for future biofuel technology, potentially helping to break the glucose-glucose bonds in cellulose more efficiently.
