Explanation:

In all living system we can always find basic elements carbon, oxygen, nitrogen and hydrogen, carbon is the basic building unit contained in living matter. The percentage of carbon in the mass of living matter is 19.0% oxygen and hydrogen are present in almost all organic compound which creates living organisms.

Farming from then till now.....
Len [333]

Answer:

Over the past century, American farming has changed dramatically. Crops with long histories like tobacco are still prevalent throughout the South, while many farmers across the country are now exploring the possibility of a thriving hemp market. Every state has a rich farming history, from the tomatoes made in New Jersey, to the sheep used for wool production in Wyoming. Currently, some farms are looking to new technology to maintain their blue-collar livelihood, while others have decided to shut down shop, unable to keep up with fluctuating markets, export worries, and other daily concerns of America’s farmers. Those aspects and more are detailed in Stacker’s dive into how American farming over the past 100 years.

Stacker compiled a list comparing agriculture in each state over the last 100 years using data from the 1920 Agriculture Census, and most recent data as of Feb. 28, 2020, from the 2019 Census State Agriculture Summaries. The 1920 Census figures were released in 1922, and even include some data for areas of the U.S. that weren’t even technically states yet, like Alaska and Hawaii (where bees were widely harvested to make honey and waxes).

While American farming has certainly expanded and increased its value since 1920, there were almost three times as many farms 100 years ago than there are today—in 1920 there were 6.5 million farms, while 2020 estimates come in at two million. Within each slide, we discuss the essence of a state’s agricultural economy then and now, significant changes in crops, legislation, and industry size, and other tidbits like where some of the earliest immigrant farmers arrived from. From Austrians in Delaware to Japanese farmers in Oregon, agricultural workers from around the world helped shape modern American farming. Click through to find out your state’s farming past, present, and future.

Is neon different from oxygen?And how is it different? Please explain.
EleoNora [17]

Neon is a member of the noble gas family. Other elements in this family includes <span>helium, argon, krypton, xenon, </span>and <span>radon. </span>These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon. Chemists have yet to prepare compounds of helium, neon, or argon.

Neon was discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961). It occurs naturally in the atmosphere, but only in very small amounts.

The image shows a paramecium and a bacterium. One of these organisms is very good at rapidly adapting to environmental changes b
Rom4ik [11]

Genetic variation enables bacteria to adapt to changes in their environment. Since, bacteria reproduce asexually (binary fission), they can share genes (genetic transfer) via other mechanisms such as conjugation (exchange of genetic material through direct contact between two bacteria), transformation, and transduction(exchange of genetic material via bacteriophages).

Transformation is a process by which bacteria takes in DNA from its environment through the cell membrane.
