Answer:
75 degrees Celsius
Explanation:
Assuming that there is no heat lost to the surrounding, heat energy would move from the water to the cup until an equilibrium temperature is reached. At equilibrium, both the water and the cup would have the same temperature the sum of which would be equal to the sum of their initial temperatures.
Sum of initial temperatures = 100 + 50 = 150 degrees Celsius
At equilibrium, the temperature is divided equally; 150/2 = 75 degrees Celsius
Hence, both the water and the cup will reach 75 degrees Celsius temperature.

The statements that are true for asexual reproduction are the mode of reproduction for Escherichia coli, a prokaryotic organism, and can occur in animals through fragmentation. The correct options are A and B.
What is asexual reproduction?Asexual reproduction is the type of reproduction in which there is no need for two parents. A single parent can generate offspring. They are of various types like budding, and binary fission. It is done in small organisms or primitive organisms.
Escherichia coli is a prokaryotic organism. It is a bacterium that reproduces by asexual reproduction. In bacteria, the cells of bacteria divide themselves and produce new cells called daughter cells.
Fragmentation is a process of reproduction in which there is the fragmentation of a body part that produces a new organism. It can be seen in a starfish.
Thus, the correct options are:
A. Mode of reproduction for Escherichia coli, a prokaryotic organism
B. Can occur in animals through fragmentation.

how does the skeletal system helps the muscular system?
Please answer this if u know it, thank you❤️
Explanation:
Single circulation is less efficient as gill capillaries slow down the blood flow so the body receives blood at a low pressure which decreases the oxygen supply to the cells.
Double circulation is more efficient as blood at higher pressure especially in humans and mammals
In single circulation only venous blood passes through the heart.
In double circulation mixed or oxygenated or venous blood passes through the heart.

Which characteristic do Venus and Earth share?
The characteristic that Venus and Earth share are similar size, mass, and density. The correct option is (B).
What are Venus and earth?The second planet from the Sun and the nearest planetary neighbor to Earth is Venus. It is one of the four inner, rocky terrestrial planets and is frequently referred to be Earth's twin due to similarities in size and density.
Venus and Earth are roughly the same sizes, mass, and density. Both have a fairly similar makeup, but Venus' atmosphere, which is made up exclusively of carbon dioxide, is not the same as Earth's. Venus rotates around the sun at the slowest rate.
Venus is frequently referred to as Earth's twin because both planets are comparable in size, surface makeup, and atmosphere, which includes a sophisticated weather system. Venus is just 30% closer to the Sun than Earth, and both planets are roughly the same size and density.
Therefore, the correct option is (B) similar size, mass, and density.

Based on the information provided;
the wavelength of the wave is 5 meter.frequency of the wave = 0.05 HzWave velocity = 0.25 m/sWhat is the wavelength of the wave?The wavelength of a wave is the distance between successive crests or troughs in a wave.
A crest in a wave is a point on the wave surface where the maximum upward displacement of the medium occurs.
A trough in a wave, is the point of the maximum downward displacement of the wave.
The distance between crests in the wave is given as 5 meters.
Thus, the wavelength of the wave is 5 meter.
The frequency of a wave is the number of complete cycles completed by the wave in one second.
From the given data, the wave takes 20 second to complete one cycle.
Therefore, frequency of the wave = 1/20
frequency of the wave = 0.05 Hz
The wave velocity or wave speed is the product of the wavelength of a wave and the frequency of the wave.
Wave velocity = 5 * 0.05
Wave velocity = 0.25 m/s

What mistake did john needham make that caused him to conclude that spontaneous generation for microorganisms occurred?.
John Needham made a mistake of re-contaminating his solutions made from cooked broth.
Needham firmly believed in the spontaneous production of microbes, as did many other scientists of the age. In 1750, he reported the findings of an experiment he had carried out in the hopes of proving the theory of spontaneous generation. His research showed that there was spontaneous generation.By executing an experiment in which he put a broth or gravy inside a container, heated the bottle to kill anything within, and then sealed it, John Needham in England refuted Redi's findings. A few days later, he revealed that there was life in the soup and declared that life had been fashioned out of nothing.However, he did a mistake where he accidentally re-contaminated his solution.

Which action would most effectively slow down the
dissolving of a sugar cube in water?
crushing the sugar
cooling the water
heating the water
stirring the water
Answer:
cooling the water
Explanation:
hot water has more energy tha cold water
Cooling the water will most effectively slow down the dissolving of a sugar cube in the water. This is basically based on the rate of dissolution property of water. Hence, option B is correct.
What is the rate of dissolution?Dissolution refers to the process by which the solute dissolves into the solvent and forms a complete solution.
Rate of dissolution refers to the time taken by a solute to dissolve into a solvent. Any solid that has to be dissolved into water depends upon the collisions between the molecules of the water and the particles of the solid substance. So, to increase the frequency of these collisions, more energy is to be transferred to the system to increase the rate of dissolution.
And, while cooling the water, we are lowering the kinetic energy between the molecules of sugar and the water, that means the collisions will occur with less force. Hence, the rate of dissolution will be lowered.
Therefore, the correct option is B where the cooling of the water will decrease the rate of dissolution of the sugar cube in the water.
