why do some dna fragments move farther than others during gel electrophoresis
Answer:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. ... DNA fragments are negatively charged, so they move towards the positive electrode. Because all DNA fragments have the same amount of charge per mass, small fragments move through the gel faster than large ones.

What happens without and with monitoring and oversight?
Answer:
Effectiveness, inaccuracies
Explanation:
In any process when monitoring and overseeing is since that process becomes more effective.
For example, if a security personnel in charge of the CCTV camera system falls asleep or is distracted, he wouldn't be able to monitor the customers inside a shopping mall, thus we know what this may result in - theft. However, he would be more effective if he monitors the activities in the shopping mall.

What is the difference in trophic level efficiency between herbivores and Carnivores?
Answer:
Herbivores eat plants who are the major producers of chemical energy in the ecosystem. Plants undergo photosynthesis through sunlight(solar energy) and other compounds such as Carbon dioxide and Water to give Oxygen and Glucose. The herbivores eat the plants directly and are able to utilize a greater percentage of energy. Carnivores eat the herbivores and get energy but in a lesser form compared to the herbivores.
This simply means trophic level efficiency in the ecosystem is higher for herbivores and lower for the carnivores.

Do plants or animals adapt to their environment faster?
Which process is shown in the diagram?
A. Cellular respiration
B. 02-CO2 cycle
C. Transpiration
D. Photosynthesis
The process shown in the diagram is Photosynthesis (option D)
What is photosynthesis?
Photosynthesis stands as an important process by which green plants, algae, and certain bacteria harness light energy, usually from the sun, and convert it into chemical energy. This intricate conversion unfolds within the chloroplasts of plant cells, chiefly employing chlorophyll, a light-absorbing pigment.
Within photosynthesis, carbon dioxide (CO2) sourced from the atmosphere and water (H2O) amalgamate under the influence of light energy, yielding glucose (a sugar variant) and oxygen (O2) as consequential products.
Answer: if photosynthesis is not an option its O2-CO2 cycle

butterflies taste with their feet, while humans taste with their tongues. in this way, butterfly feet and human tongues are ------------ structures
Answer:
analogous
Explanation:
They share the same function but have different evelutionary origins.
Final answer:
Butterfly feet and human tongues are analogous structures in biology.
Explanation:
This question can be easily answered by having basic understanding of the concepts of functionality and usage and the application of the same.
In biology, butterfly feet and human tongues are analogous structures. Analogous structures are similar in function and appearance but do not share an evolutionary history. While butterflies taste with their feet, humans taste with their tongues. Both butterflies and humans have structures that allow them to detect and interpret taste, but the specific anatomical features and mechanisms differ.
Therefore, butterfly feet and human tongues are analogous structures in biology

What is it called when the forest remains but its richness and well-being have deteriorated?
Answer: Biodiversity loss
Explanation:
The biodiversity can be defined as the variety of life forms on earth or any other region. The forests are rich sources of biodiversity. The hunting, poaching, animal trafficking, and other ill-legal related human activities are like to reduce the species richness in forests. As many species are dependent upon other species for food, mate and other requirements for completing the life cycle thus the well-being of the forests will get deteriorated by the loss of biodiversity.
The process by which a forest remains but its richness and well-being have deteriorated is called forest DEGRADATION.
Forest degradation refers to the process in which species richness and wealth of a forest region is permanently declined as a consequence of diverse factors.
The most important factors associated with forest degradation include anthropic factors (i.e., human factors) and environmental factors.
For example, overgrazing and demand for fuelwood are common anthropic factors associated with forest degradation.
In conclusion, the process by which a forest remains but its richness and well-being have deteriorated is known as DEGRADATION.

A habitat can keep only a certain number of plants and animals alive. Changes in a habitat can affect the survival of plants and animals.
Choose each correct statement by clicking on it.
Clearing land to build homes or buildings changes a natural habitat and can force animals to move to another location to survive.
Fires, hurricanes, volcanoes, and earthquakes are examples of natural habitat changes that occur rapidly.
Changes in temperature or amount of rainfall(drought or flood) are examples of slow habitat changes that occur naturally.
Soil erosion is an example of a slow habitat change that occurs naturally and leads to the survival of fewer plants.
The development and use of farmland does not change the habitat of plants that naturally grow in an area.
When other animals or plants move into a habitat, they change the habitat by taking up needed space and food.
Extinction (loss of an entire group of organisms) can occur if animals or plants cannot adapt to changes in their habitat.
Answer:
all of them are correct except for "the development and use of farmland does NOT change the habitat of plants that naturally grow in an area"
Explanation:
This is not true because for farmland, farmers clear hundreds of trees in order to have flat land for cattle. They also clear plants for growing food as well but this is less catastrophic than the huge amount of land cleared for cattle.
Final answer:
The correct statements regarding habitat destruction effects on plants and animals include how both natural and human-induced changes can force animals to relocate, alter ecosystems, and potentially lead to species extinction. Incorrectly, the development of farmland also changes the habitat, contrary to one of the statements.
Explanation:
The question revolves around the concept of habitat destruction and its consequences on the survival of plants and animals. Here is a clarification of each statement:
Clearing land to build homes or buildings changes a natural habitat and can force animals to move to another location to survive - Correct. This is an example of human-induced habitat destruction.Fires, hurricanes, volcanoes, and earthquakes are examples of natural habitat changes that occur rapidly - Correct. These are natural disturbances that can significantly alter habitats.Changes in temperature or amount of rainfall (drought or flood) are examples of slow habitat changes that occur naturally - Correct. These gradual changes can affect habitat suitability over time.Soil erosion is an example of a slow habitat change that occurs naturally and leads to the survival of fewer plants - Correct. It affects the soil's fertility and structure, essential for plant growth.The development and use of farmland do not change the habitat of plants that naturally grow in an area - Incorrect. Conversion of land to farmland changes the natural habitat and can prevent the growth of native plant species.When other animals or plants move into a habitat, they change the habitat by taking up needed space and food - Correct. Invasive species can outcompete native species for resources.Extinction (loss of an entire group of organisms) can occur if animals or plants cannot adapt to changes in their habitat - Correct. The inability to adapt can lead to extinction.Mammals get rid of metabolic waste to retain homeostasis. The kidneys filter urea to retain water. This is called

Explanation:
Describe the direction of the flow of thermal energy if a bowl of ice cream sits on the counter of the kitchen.
Answer:
The bowl of ice cream contains ice cream with temperature below freezing point. A hot body contains more thermal energy than a cold body. Thermal energy only flows from a hot body to a cold body, and not the reverse.
The bowl of ice cream contain less thermal energy than it sorrounding envoirment (air and the kitchen counter), this creates a temperature gradient that forces thermal energy from the sorrounding envoirment into the bowl of ice cream because, according to thermodynamics, all bodies always tend to be in thermal equilibrium with its sorrounding. The thermal energy flows into the bowl of ice cream until it has the same thermal energy with its sorrounding; bringing the thermal gradient between them to zero.
