Thompson Scatter radioactive particles It is a spherical object containing electrons in a massive positive charge distribution
Bohr Check the spinning motion of electrons Electrons are found outside the nucleus of the atom at various levels called shells, arranged like layers of an onion
Which of these statements best explains why Thompson and Bohr visualized the atom differently?
Atoms change their structure and particles from time to time.
Atoms cannot be described easily with the help of only one model.
Scientists do not agree with each other to strengthen science.
Scientists with varied experimental processes and interests perceive things differently.
Researchers accept proposing speculations that negate current hypotheses. So, the proper alternative is D i.e., Scientists with varied experimental processes and interests perceive things differently.
As of late, the structure of molecules has been found. Sometime recently the perfect demonstration of a molecule was found, and a few others were proposed and abandoned.
In J.J. Thomson's theory, Thomson compared the definition of an iota to that of a Christmas pudding. He claimed that atoms are made up of an emphatically charged circle with inserted electrons.
Additionally, he claimed that since the sizes of positive and negative charges break even, an iota as an entirety is electrically impartial.
Rutherford tested with α-particle diffusing on a gold sheet. He took note that the lion's share of the negative particles did not divert when they voyage through the gold foil.

What type of molecule is represented by the model below?
The molecule represented below is that of a cholesterol. Therefore, option (C) is correct answer.
What is cholesterol?Cholesterol is waxy. It's not always "bad." Cells, vitamins, and hormones require it. But too much cholesterol is bad. Cholesterol has two origins. Your liver produces all your cholesterol. Animal meals supply the rest of your cholesterol. Meat, poultry, and dairy contain cholesterol.
Cholesterol can be written as the chemical formula C27H46O. According to this interpretation, it is made up of 27 atoms of carbon, 46 atoms of hydrogen, and one atom of oxygen. The structure of cholesterol has a core sterol nucleus that is surrounded by four hydrocarbon rings. These rings are made up of hydrogen and carbon atoms arranged in a circular pattern.

Which of the following is the best example of an adaptation that helps an organism survive in its environment?A. Green coloring on a lizard living one red and brown rocksB. A thick coat of fur on an animal that lives in the desertC. A long root system in a desert plantD. Thin, delicate leaves on a plant that lives in the tundra
An adaptation that helps an organism survive in its environment would be an adaptation that helps this organism get food/water, hide from predators, not loose too many water or nutrients, etc.
A green lizard living in red and brow rocks would cause a great contrast between the colors, putting the lizard in evidence and making it easier for predators to find it. Therefore, A is incorrect.
The adapted leaves of plant from the tundra will be small and waxy, but not too thin as it will try to keep more water inside it than being lost in transpiration. Therefore, D is also incorrect.
An animal that lives in the desert can't have a thick coat of fur because it will make the animal be super heated, causing loss of water that is so important to keep in a desert. So B is incorrect too.
In deserts that are no water easily available, so a plant can have a long root system in order to get water from deep below the surface of the ground. Therefore, the correct answer is C. A long root system in a desert plant

The gray wolf at one point almost caused the extinction of a certain species of rabbits in the Northwest. The initial abundance of rabbits allowed the gray wolves to hunt easily and eat many rabbits. Eventually the rabbit population began to decrease, resulting in a change in the wolf population.
1. The predator in this scenario is Gray Wolf while the prey is the Rabbit population.
2. Since, the rabbit population is the food of gray wolves, the depletion of rabbits will also increase the intraspecific competition among gray wolfs. this will further lead to an imbalance in the ecosystem and the gray wolf population will also decrease.
3. Decreasing the population of gray wolves in the area will automatically reduce the killing of rabbits. In this way, a balance will be maintained. Therefore the extinction of no species will occur in that area.

which is one major difference between anaerobic and aerobic respiration?
Answer:
the anaerobic is a different form
One major difference between anaerobic and aerobic respiration is the electron acceptor. The correct option is b.
What is aerobic respiration?Aerobic respiration occurs in a cell when glucose is broken down with the help of oxygen to produce carbon dioxide, water, and the release of energy. For instance, aerobic respiration occurs in mitochondria.
Anaerobic respiration, on the other hand, is the breakdown of glucose without the use of oxygen in a cell, producing alcohol, carbon dioxide, and the release of energy. Yeasts, for instance, breathe anaerobically.
We can therefore draw the conclusion that the primary distinction between aerobic and anaerobic respiration is that the former requires oxygen while the latter does not.
Therefore, the correct option is b, electron acceptor.

Why would it be useful for the SAME cell to be able to make different kinds of proteins at different times? Give an example, or make one up.
The cell is a complex system with specialized organelles and cellular machinery. The cell in an organisms have the same genetic material (DNA), but each cells only produce the proteins that they need in the moment or function that they are needed, that's because the cell have a "intelligent" intrecellular signaling and organization system. Some examples of these hability of the cells to control the production and liberation of proteins is the cell differentiation and the case of cells that have the function of producing protein hormones (insulin, glucagon, pituitary hormones, and hypothalamic hormones), it is important to the cells to have the control of which they produce because one cell have more autonomy and with only one genetic code an organism com be self-sufficient (molecular) and with internal protein variability.

Fossil fuels are nonrenewable energy resources that are rich in carbon. Examplesof fossil fuels include oil, natural gas, and coal.How are oil and natural gas resources extracted?
Answer
oil and natural gas are extracted via a process called hydraulic fracking.
Conventional natural gas and oil deposits are found in permeable rocks, trapped below impermeable rock. These deposits can be extracted by drilling down through the impermeable rock into the permeable rock.
But gas and oil are also trapped in the spaces within impermeable shale rock. Therefore, because shale is impermeable, simply drilling down to it is not enough to extract these deposits. Instead the process of hydraulic fracturing, known commonly as fracking, is used. The rock has to be fractured to get the gas or oil out
