The charged particles in the beams that Thomson studied came from atoms. As these particles moved away from their original atoms, they formed a visible beam. The current model of the atom includes protons, neutrons, and electrons.
What is the best use of an atomic model to explain the charge of the particles in Thomson’s beams?
An atom’s negative particles are surrounded by positive matter, so the positive particles are easier to remove.
An atom’s positive particles are surrounded by negative matter, so the negative particles are easier to remove.
An atom’s smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.
An atom’s larger positive particles are at a distance from the central negative particles, so the positive particles are easier to remove.
The question to the above information is;

Short term atmospheric conditions give information regarding the weather in an area and Long-term precipitation and temperature data can give an indication of the climate of an area, both statement true.
What are weather and climate conditions?Weather is the collective name for the momentary properties of the lower atmosphere, including precipitation, temperature, humidity, wind speed, direction, and atmospheric pressure. The possibilities are endless: it may be bright, cloudy, rainy, foggy, chilly, hot, windy, stormy, snowy, etc.
Seasons, documented climate cycles, or volcanism are frequently to blame for short-term climate change, which affects shorter timescales.
Long-term climate change affects longer time periods and may be brought on by human activity, variations in the sun's output, or a sluggish recovery from the Flood.
Therefore, weather refers to atmospheric circumstances for a brief period of time, whereas climate refers to long-term, predictable atmospheric conditions.

magnetic field.
Answer: Stronger Magnetic Field
Explanation:
The magnetic field in a solenoid is given by
[tex]B=\mu nI[/tex]
where B=magnetic field
[tex]\mu=[/tex]Permeability
n=no of turns per unit length
I=Current through solenoid
When No of turns increases, it increases the strength of the magnetic field.

Anaerobes carry on whereas aerobes carry on cellular respiration
Answer:
Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.
Explanation:
Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
Aerobic Respiration
Occurs in the presence of free oxygen.Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules. Respiration occurs in the mitochondria.Takes place in two steps or stages: Krebs cycle and electron transporter chain. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.Anaerobic Respiration
Occurs in the absence of free oxygenSeries of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation. Lactic fermentation produces lactic acid and 2 ATPAlcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂The whole anaerobic process occurs outside the mitochondria.Overgrazing reduces grass cover and negatively impacts the soil health by reducing it's ability to hold water .

A. Allow developers to buy rachlands for housing .
B. practice moving confined cattle every few days
C. Allow unlimited animals to graze in a given area to reach carrying capacity.
D. practice grazing an area of land at the same stage of plant growth each year .
Answer: C. Allow unlimited animals to graze in a given area to reach carrying capacity.
Explanation: I choose this as the answer because the animals grazing in the wrong parts be part of the reason the soil can't hold the water it needs, so allowing animals in a particular area that's less of a problem with Overgrazing would be helpful

Answer:
B
Explanation:

When a gas obeys Boyle's law, the temperature is held constant. The correct option is C.
What is Boyle's law?Boyle's law is given by Charles Boyle. It is a gas law that states the pressure decrease with the increase in the volume and the temperature remain constant. In other words, the pressure exerted on gas is inversely proportional to the volume of the gas.
The law shows the relationship between pressure and volume, with the temperature remaining constant. There are three gas laws which are given by different scientists. These laws show the relationship between two variables and the third remains constant. These variables are temperature, volume, and pressure.
Thus, the correct option is C. temperature regarding the gas obeys Boyle's law, and it remains constant.

what is a sedimentary rock
Answer:
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding. Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified – turned to rock. Sedimentary rocks can be formed in deserts, lakes, rivers and seas .
(Uhm help?) The law of conservation of energy states that when there is an energy transfer or transformation, energy is lost.
Assuming this is a true/false question, the answer would be false.
According to the law of conservation of energy, energy is neither created nor destroyed; it simply changes forms.
Unless you are saying that some energy would be lost as heat, This is true.
Answer:
ae you trying to find the meaning?
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. The only way to use energy is to transform energy from one form to another.
ex: the cue ball is shot at a stationary 8 ball. The cue ball has energy. When the cue ball hits the 8 ball, the energy transfers from the cue ball to the 8 ball, sending the 8 ball into motion. The cue ball loses energy because the energy it had has been transferred to the 8 ball, so the cue ball slows down.
Give three differences between parenchyma and selerenchyma?
Answer:
Parenchyma cells have thin primary walls and usually remain alive after they become mature while Sclerenchyma cells have thick lignified secondary walls and often die when mature.
Parenchyma forms the "filler" tissue in the soft parts of plants while Sclerenchyma provides the main structural support to a plant.
Parenchyma cells are usually loosely packed with large intercellular space while Sclerenchyma cells has no intercellular spaces between the cells.
