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.

Which restriction endonucleases would cleave a dna molecule at the given sequences? the complementary dna substrate strand is omitted for clarity.
The types of restriction endonucleases that would cleave a DNA molecule at the given sequences are type I and type II restriction endonucleases.
What do you mean by Restriction endonucleases?Restriction endonucleases may be defined as a protein constructed by bacteria that cleaves DNA at specific sites along the molecule.
Among the type I and type II restriction endonucleases, type II restriction endonuclease cuts the DNA molecules more efficiently and is widely used for the same procedure as compared to type I restriction endonucleases.

Select the correct answer. mathew claims that people should invest in alternative sources of energy rather than burning fossil fuels. he has put together two graphs as evidence. the first compares how human use of fossil fuels affects atmospheric carbon dioxide levels, and the second shows how land-ocean temperatures on earth have changed over time. which statement correctly supports his claim based on evidence from the graphs? a graph showing the increasing trend of carbon emissions from 1800 to 2004, a graph showing the increasing trend of annual mean temperature from 1880 to 2015 a. more carbon in the atmosphere likely absorbs more heat energy, thus increasing the temperature. b. petroleum should replace natural gas, since it releases less carbon dioxide. c. burning coal does not contribute to a rise in carbon dioxide or temperature. d. carbon dioxide emissions from burning fossil fuels has decreased over time. e. the graphs show no possible correlation between burning fossil fuels and increasing temperatures.
The evidence from the graphs is that more carbon in the atmosphere is likely to absorb more heat energy, thus raising the temperature.
Why does carbon raise the temperature?The feature is important because the effect of sunlight on the Earth's surface, including the oceans, is reflected in the form of infrared rays. By absorbing this radiation, the gases heat up the entire atmosphere as if they were a blanket that keeps the planet warm.
Whit this information, we can conclude that the evidence from the graphs is that more carbon in the atmosphere is likely to absorb more heat energy, thus raising the temperature.

Activities that reduce solid waste are composting food instead of throwing it in the garbage. Hence, option C is correct.
How can solid waste be reduced?Solid waste can be reduced through various measures, some of which are:
Reduce, Reuse, and Recycle: The three Rs of waste reduction can help in reducing the amount of solid waste generated. By reducing the consumption of products, reusing items, and recycling materials, less waste is sent to landfills.
Composting: Organic waste such as food scraps, yard waste, and paper products can be composted to produce nutrient-rich soil for gardening.
Avoiding single-use items: Single-use items such as plastic bags, straws, and disposable cups can be avoided by using reusable alternatives.
Buying in bulk: Buying products in bulk can help reduce packaging waste.
Donating items: Items that are still in good condition but are no longer needed can be donated to local charities or thrift stores. Hence, option C is correct.

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.

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.
