Answers
Answer:
A. Antibiotic resistance can sometimes be shared among bacteria.
B. Mutation can cause antibiotic resistance.
D. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection.
Explanation:
Identifying: Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids (not a bilayer). ... Bacteria: cell membrane contains ester bonds; cell wall made of peptidoglycan; have only one RNA polymerase; react to antibiotics in a different way than archea do.
Hope this helps, I reported some answer that was absurd, not applicable, incomplete and confusing
Mutation can cause antibiotic resistance, Bacteria that become resistant are an example of evolution. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection The correct options are B, D, and C.
What are archaebacteria and bacteria?Archaea, like bacteria, lack interior membranes but have a cell wall and swim with flagella.
Archaea differ from bacteria in that their cell wall lacks peptidoglycan and their cell membrane contains ether linked lipids rather than ester linked lipids.
The dispersion of antibiotic resistance in pathogenic bacteria is a simple and elegant example of natural selection at work.
Bacteria can develop antibiotic resistance through mutations that alter antibiotic cellular targets or by acquiring dedicated resistance genes from other bacteria.
Antibiotic resistance can be caused by mutation; bacteria that become resistant are an example of evolution. Natural selection is demonstrated by antibiotics killing bacteria while allowing mutated bacteria to live.
Thus, B, D, and C are correct options.

Which of these layers is found directly above the Earth's core?
Group of answer choices
Outer core
Mantle
Inner core
Crust
Answers
Answer: Mantle
Explanation:
there are 3 layers of the earth- core, mantle and crust. The layer found directly above the earth's core is the mantle.
Answer:
The answer depends on what you are taking about: the outer core or the inner core?
Answer: Mantle
Explanation:
If you find a picture of the Earth's layers, you can see that the inner core is the bottommost layer. However, if you combine the Inner Core and Outer Core, that could be determined as the Earth's core.
I would chose the Mantle because if the two cores are combined, the layer directly above them is the Mantle.

How is energy converted in a hydroelectric plant?
The potential energy of water is converted to electrical energy when water flows past a generator.
The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy.
The kinetic energy of water is converted to electrical energy when water flows down the dam's channel and into the transformer.
The potential energy of water turns the generator's turbines, which results in the production of electrical energy.
Answers
Answer:
Energy is converted in a hydroelectric plant as follows;
The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy
Explanation:
The water in an hydroelectric plant is given potential energy by building an artificial dam to raise the height of the water above the turbine
The high potential energy of the water is converted to kinetic energy which provides the power that turns the turbine transforming the kinetic energy of the water into rotational kinetic energy of the turbine by conservation of mechanical energy;
The shaft connected between the turbine and the generator, turns the generator by the mechanical energy of the turbine and as the generator turns in a magnetic field, electricity is produced by magnetic induction according to Faraday's law.

student determined that only 110mL of water was actually formed. What is the
percent yield of this reaction?
Answers
Answer:
88%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
110/125 = 0.88

Answers
Answer:
i think it is..... smaller than normal range of highs and low tides
Moon and Sun are at right angles to the Earth
Explanation:
Moon and Sun are at right angles to the Earth and gravity of the Sun and Moon work against is the right statement about NEAP tides.
What are tides?Tides are the cyclic deformation of water body occur due to external gravitational force.
NEAP tides are also known as small tides as their heights are not very much and this is occur due to opposite attraction of water towards the gravity of the sun and moon. As sun and moon are present in the right angle direction with respect to the earth.
Hence, option (1) & (2) is correct, i.e. gravity of sun and moon is opposite and they are present at the right angle to the earth.
