Answer:
false
Explanation:
"Electrons are the "material" of the charge that is flowing. Therefore, current can never cause a metal object to become positively or negatively charged, because the net number of electrons in the metal object will never change due to current flow."

What hypothesis was validated by using paleo-magnetism?
Question 8 options:
a) subduction
b) hot spots
c) seafloor spreading
Answer:
C). Seafloor spreading.
Explanation:
Paleomagnetism is characterized as the 'study of the account of direction and strength of magnetic fields of the Earth in sediments, rocks, etc.' The hypothesis that was authenticated by using this study would be 'seafloor spreading' by displaying that magnetic reversal as strips of rotating polarity in gradually disseminating seafloor. This description of magnetic stripping by employing paleo-magnetism made the scientists believe that alternate crusts are being frequently made under ocean/sea. Thus, option C is the correct answer.

Rabbits normally eat some grass as a food source. In a habitat, a new species of grass is introduced that out-competes most of the original species of grass. The new species of grass contains a chemical that is usually toxic and fatal to most rabbits. Assuming that all rabbits in this habitat will eat some of the new species of grass, how will the presence of the new grass most likely decrease the diversity of the rabbit population in this habitat?
Answer:
Well The Diversity will decrease.
Explanation:
If the Grass Is Toxic to the Rabbit than the rabbits will either die from eating the grass, or they will stop eating it and need to find a new food source. this will lead to the to the rabbits that are resistant to the toxic grass being able to reproduce more and therefor becoming more abundant.

Since the elephant’s diet consists of play material only, where would the elephant get the missing element needed to make collagen (or any protein)?
Answer:
The elephant is a herbivores animal and feeds on plant material that consist of cellulose. Collagen is a type of protein that is absent in plant material and only found in skin, tendons, bones and muscles. The elephant also requires collagen to replace or repair their skin cell in every 2 weeks.
As elephants are unable to consume meat that contains collagen, they get collagen or protein from the plant material only with the help of bacteria or enzymes present in its guts. The bacteria having enzymes that helps in the breakdown of cellulose and access the proteins, fat or sugar present in the plant cell.
Elephants get collagen and other proteins from the vegetables they consume.
We can arrive at this answer because:
Collagen is essential for the maintenance of the skin.However, collagen is found in large amounts in meat.Few vegetables have collagen and elephants only feed on vegetables.However, the demand for collagen in the elephants' body is met by feeding on vegetables rich in cellulose and vitamin C.When cellulose is digested and vitamin C is used in the body, collagen production is stimulated.

How are fossils that contain vestigial organs consistent with common ancestry?
Answer:
Explanation:
La evidencia de un antepasado común en los seres vivos, que han encontrado durante décadas científicos que trabajan en numerosos campos, demuestra la descendencia común de estos seres, que la vida en la Tierra se desarrolló a partir de un último antepasado universal, que la evolución existe y que puede demostrar los procesos naturales que han dado como resultado la biodiversidad de la vida en la Tierra. Esta evidencia apoya la síntesis evolutiva moderna, la actual teoría científica que explica cómo y por qué cambia la vida a lo largo del tiempo. Los biólogos evolucionistas han documentado evidencias de antepasados comunes realizando predicciones verificables, probando hipótesis y desarrollando teorías que ilustran y describen sus causas.
La comparación de secuencias genéticas de ADN ha revelado que los organismos filogenéticamente próximos tienen un mayor grado de similitud secuencial que los organismos filogenéticamente alejados. Se pueden encontrar más pruebas de la descendencia común en detritus genéticos como los pseudogenes, regiones del ADN ortólogas a un gen en un organismo relacionado, pero que ya no tienen actividad y parecen estar experimentando un proceso continuo de degeneración por acumulación de mutaciones.
The air pressure at City A is 1,018 mb, and the air pressure at City B is 980 mb. What will most likely occur due to the pressure gradient present between City A and City B?
Answer:
There are three main causes of change in population: births, deaths and imigration flow. The Coronavirus has affected two of these three factors. The death rate has increased substantially since the pandemic hit. In under 6 months, more than 200,000 people have died. This drastic number of deaths in such a short amount of time is bound to decrease the population of the United States by a considerable margin. Immigration flow has also halted since the beginning of the pandemic. Travel bans and the close monitoring of borders has ensured that the number of immigrants entering the United States has decresed greatly.
Most likely the pressure gradient present between City A and City B that is City A is 1,018 mb, and City B is 980 mb, will - The high-pressure system at City A will create winds that blow toward the low-pressure system at City B.
A force exerted on a surface by the air above it as gravity pulls it to Earth is called air pressure or atmospheric pressure. Atmospheric pressure is commonly measured with a barometer.
it determines wind and weather patterns across the globewinds move from high air pressure to low air pressureIt leads directly to wind and influences the speed and direction of that wind.Pressure differences or gradients also affect larger weather systems like storms.Thus, Most likely the pressure gradient present between City A and City B that is City A is 1,018 mb, and City B is 980 mb, will - The high-pressure system at City A will create winds that blow toward the low-pressure system at City B.

Which of the following describes a virus?
A. A virus does not have a cell wall, nucleus, and eats.
B. A virus has a cell, a nucleus, and does not eat.
C. A virus does not eat, use energy, or have cells.
D. A virus does not have a cell, produces carbon dioxide, and uses oxygen.
A virus does not eat, use energy, or have cells. The correct option is C.
What is basically a virus?A virus is an infectious microbe made up of a nucleic acid segment (either DNA or RNA) surrounded by a protein coat.
A virus cannot replicate on its own; instead, it must infect cells and use host cell components to replicate itself.
Viruses are bundles of nucleic acid DNA or RNA encased in a protein shell called a capsid.
Viruses are the most abundant life form on the planet, according to some estimates; they are 10 times more numerous than bacteria.
Viruses could have evolved from mobile genetic elements with the ability to move between cells.
Thus, the correct option is C as a virus does not consume food, generate energy, or have cells..

Where is the main store of phosphorus ?
Answer:
Phosphorus is most commonly found in rock formations and ocean sediments as phosphate salts.
Answer:
The largest reservoir of phosphorus is in sedimentary rock. It is in these rocks where the phosphorus cycle begins. When it rains, phosphates are removed from the rocks (via weathering) and are distributed throughout both soils and water. Plants take up the phosphate ions from the soil.
