Answer 1

What does vishnu mean when he states "ones duty, though defective, is better than another's duty well preformed. Performing the duty prescribed by nature, one does not incur sin"

Answers

Answer:

It is better to do what you are supposed to do, than doing someone else's better

Vishnu says, "One's duty, while imperfect, is better than another's duty well performed," he means exactly what he says. Doing what you are meant to do is preferable to doing it better than someone else.

What is duty?

A responsibility is something that a citizen is compelled to do by law (also known as an obligation). Following the law, paying taxes, defending the country, and sitting on juries are a few examples of obligations. Rule of Law: The law applies to everyone. Knowing the law is necessary for compliance.

Vishnu means exactly what he says when he says, "One's duty, while flawed, is better than another's duty fully fulfilled." It is preferable to fulfill your purpose than to outperform others in it.

Therefore, "One's duty, while imperfect, is better than another's duty well performed,"

Answers

Answer: a.  Evaporation, b. Condensation c. precipitation d. groundwater

Explanation:

Answer: A. Evaporation B. Condensation C. Precipitation D. Groundwater

Explanation:

I also put this as my answer:

Water cycle starts with the evaporation of surface water of rivers, lakes, oceans etc.As the water vapors move up in the atmosphere, the temperature decreases due to which they begin to condense which results in the formation of clouds. The tiny droplets of water vapors keep on merging with each other to form larger drops. Under the influence of temperature and gravity, the water precipitated in the form of rain, snow, etc.The water then runoffs the ground and percolate into the soil to form groundwater.

Using complete sentences, describe what present-day Canada and the United States looked like just prior to conta between Europeans and Native Americans.​

Answers

Answer:

Canada and the US, prior to the contact between Europeans and Native Americans, were home to numerous civilizations, a huge number of settlements, an agricultural landscape, and a lot of different cultures.

Explanation:

Present-day Canada and the United States, prior to the contact between the Europeans and Native Americans were very different places. The Native Americans were in very large numbers, though much more in the US and less in Canada. There were a lot of thriving civilizations across the continent, and the different groups of people had different lifestyles.

Across North America, there were thousands of settlements, some of which were cities or villages, while some were temporary dwellings. Unlike the common belief, the Native Americans, at least the ones that had a settled lifestyle, were on a relatively similar level of development as the Europeans, and they exploited the continent a lot. The landscape was changing from one place to another because of the type of human activity that was dominant, and what is now the US especially, was much less forested because of agricultural activities than what the Europeans saw after they started to move westward sometime after their initial arrival.

with reference to temperature and rainfall identify and explain the differences in the climatic zones​

Answers

Answer:

Temperature and precipitation are the basic and detrimental factors when it comes to climate types.

Explanation:

There are multiple different climate types across the globe. There are numerous factors that influence their characteristics, but the most important are temperature and precipitation. The warmer and wetter it is, the more organisms thrive, and the colder or hotter and drier it is, the fewer organisms thrive.

The tropical rainforests have high amounts of precipitation and high temperatures all year round, thus they have high biodiversity. The deserts have very high temperatures (some also very low in winter) and lack of precipitation, so there is very little biodiversity.The temperate climates have medium amounts of precipitation and high variation in temperature from one to another season, leading to having moderate biodiversity.The polar climates have very low temperatures and very low precipitation, so they have the least biodiversity.

Evaluate the extent to which religious belief shaped societies before 1200 CE

Answers

Answer:

Before 1200 CE, religious belief had a huge impact on societies and how they functioned.

Explanation:

Religious belief has most probably occurred as early as the appearance of modern-day humans. Throughout human history, it has had a huge influence on societies and how they function. This was simply due to the fact that humans had very limited knowledge so religion was used to explain things, as well as to justify certain actions.

t Religion had such a stronghold until 1200 CE, and since then its influence has been gradually declining. Religion had such a big influence on societies that very often the religious authorities were even more powerful than the political figures, or they were the same. The influence was not just seen in public, but also in the private lives of the people, and unfortunately, often it has been abused to have full control of the people and their actions and punish or even kill the ones that dared to do things differently.
