Write 2-3 sentences to show your understanding of how the following words connect together in the water cycle: Evaporation, Condensation, Precipitation, Freezing, Melting
The water cycle is responsible for the regulation of temperature in our surroundings. It modifies the weather and causes rain. It is important for the circulation of various minerals throughout the environment.
What do you mean by the Water cycle?The water cycle may be defined as the continuous process by which water is circulated throughout the earth and the atmosphere through evaporation, condensation, precipitation, vaporization, etc.
Evaporation: It is a process through which water changes its liquid state into a gaseous or vapor state. It is the first step of the water cycle.
Condensation: It is the opposite as compared to evaporation. It involves the process of water vapor changing back into liquid water.
Precipitation: This process is responsible for the rain to occur. It involves the gathering of water vapor to synthesize bigger and bigger droplets of water.
Freezing: Freezing is responsible for the formation of ice in glaciers, at low temperatures, etc. It involves the process of changing liquid water into a solid form.
Melting: This process is just the opposite of freezing. Hence, it involves the transformation of a solid form of water which is ice into a liquid form.
Therefore, it is well described above.

Explanation:
what is the water cycle and explain along with the process!
Answer:
The water cycle is a process in which water is lost from water bodies and then it again comes back to earth in form of rain. This is how I know it, but the explanation is correct.
Explanation:
See,
Water from water bodies evaporates and becomes water vapour due to heatThis then reaches high altitudes, where it condenses with dirt to create small droplets thingyThis then creates a cloud, which on correct saturation with water, makes it rains.This cycle goes on continuously creating a cycle which is termed the water cycle.

How did the bacteria population become more resistant in Addie and our community?
Answer:
it's due to global warming and the increasing of population
also some how deforestation also
Answer: The environmental change put selection pressure on the population of the bacteria so that some trait variations had a competitive advantage for surviving over time.
Explanation: So, in Addie’s case, the environmental change was the antibiotics. The antibiotics led to the weaker bacteria to die off while the stronger bacteria reproduced and grew larger in population. This is called selection pressure. So to sum it all up, the bacteria population became more resistant because of the pressure selection out into them by the antibiotics. So, the weaker bacteria died off and the stronger one grew larger and larger, becoming antibiotic resistant. Sorry if I’m too late but I hope this clarifies your question!

The position of the moon, earth, and sun decides whether a high or a low tide will occur. When the sun and the moon are at right angles to each other then the gravitational pull of both the sun and the moon are canceled out. So the correct answer is option C. 11-B,12- B, 13-D, 14-C, 15-C, 16-C, 17-A, 18-B.
What is a gravitational pull?A gravitational pull is a force that causes two to be pulled towards each other. Any object having mass has a gravitational force. The greater the mass of the object, the greater the gravitational pull. Gravity helps to hold the planets in their orbit around the sun and keeps the moon in its orbit around the Earth.
The gravitational pull is also responsible for causing high and low tides. The side of the earth which is closest to the moon, experiences a strong gravitational pull of the moon resulting in a high tide. The side of the earth which is away from the moon also experiences a strong gravitational pull due to the earth’s rotational force. So this side too faces the high tide.
