Answer:
Different traits are inherited separately.
Explanation:
This question can be answered using Mendel's second law, known as the law of independent segregation.
To create this law, Mendel used two types of peas: yellow and smooth seed peas (VVRR) and green and rough seed peas (vvrr).
Mendel crossed these two peas resulting in a totally heterozygous offspring (VvRr), that is, the offspring (F1) generated by crossing two homozygous peas generated a completely heterozygous population, which Mendel called a dihybrid.
Mendel performed this crossing to learn how the transmission of traits was passed from parents to offspring. To do this, he should know whether the "V" and "R" alleles were inherited together or separately, independently.
It was at that moment that Mendel crossed the dihybrid individuals and realized that offspring (F2) had a phenotypic ratio equal to 9: 3: 3: 1. He tested several different types of peas and realized that the F2 generation always had a 9: 3: 3: 1 phenotypic ratio. With that, he concluded that the alleles were inherited independently, since the F2 generation had many variations and this would not happen if the characteristics were inherited together.
Mendel's experiment with dihybrid crosses allowed him to conclude that the different characteristics are inherited separately.
Answer: B
Explanation:
All vascular plants are multicellular.
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.
