there were 100,000 cattle in just one feedlot down here. how much corn was grown for them?
It is not possible to determine the amount of corn grown specifically for the 100,000 cattle in one feedlot without additional information. There are several factors that determine the amount of corn needed to feed cattle in a feedlot, including:
Feed Conversion Ratio (FCR): This refers to the amount of feed required to produce a unit of weight gain in cattle. The FCR varies depending on the breed, age, and weight of the cattle, as well as the type of feed used.
Feed Requirements: The feed requirements for cattle also vary based on their age, weight, and breed. Lighter and younger cattle generally require less feed compared to older and heavier cattle.
Feed Composition: The composition of the feed also affects the amount of corn required to feed the cattle. Cattle feed typically includes corn, soybean meal, and other additives, and the proportion of each ingredient affects the amount of feed required.
Therefore, without knowing the FCR, feed requirements, and feed composition, it is not possible to determine the amount of corn grown for the 100,000 cattle in the feedlot.

How did Griffith transform the non pathogenic bacteria into a pathogenic strain?
When a pathogenic strain of bacteria is combined with a live, nonpathogenic strain by Griffith, the living cells of the nonpathogenic strain become pathogenic.
In this experiment of Griffith, heat was used to destroy bacteria from the III-S strain, and the resulting byproducts were mixed with bacteria from the II-R strain. Both together killed the host, but neither one hurt the mice when used alone. The blood of these dead mice also allowed Griffith to isolate living II-R and live III-S pneumococcal strains. According to Griffith, a "transforming principle" that was somehow a part of the dead III-S strain bacteria caused the type II-R to be "converted" into the lethal III-S strain.
Who was Griffith?Frederick Griffith was a British bacteriologist known for discovering the "transforming principle" in 1928 through an experiment with bacteria which led to the understanding that DNA serves as the carrier of genetic information.
What is nonpathogenic strain?The strains of a species that are healthy without any disease are the nonpathogenic strains.

How is blood routed through the digestive system? Which nutrients enter the bloodstream directly? Which are first absorbed into the lymph?
The digestive system is a complex network of organs responsible for breaking down food into smaller components that can be absorbed and utilized by the body. One of the ways that the digestive system carries out this task is by routing blood through its various parts, which allows for the extraction and transportation of essential nutrients.
In general, blood is delivered to the digestive organs via the hepatic portal vein, which carries blood rich in nutrients from the small intestine to the liver. The liver then processes the nutrients and releases them into the general circulation via the hepatic veins.
Some nutrients, such as glucose and amino acids, are absorbed directly into the bloodstream from the small intestine. This occurs through the process of active transport, in which specialized cells in the intestinal wall pump these nutrients from the lumen of the intestine into the bloodstream.
Other nutrients, such as lipids and some vitamins, are first absorbed into the lymphatic system before entering the bloodstream. This occurs because these nutrients are not water-soluble and therefore cannot diffuse directly into the bloodstream. Instead, they are packaged into tiny droplets called chylomicrons and transported through the lymphatic vessels to the bloodstream.
In summary, the digestive system routes blood through its various parts to extract and transport essential nutrients to the rest of the body. Some nutrients are absorbed directly into the bloodstream, while others are first absorbed into the lymphatic system before entering the bloodstream.

Do you think it would be more difficult to use medicine to get rid of a virus using the Lytic cycle or a virus using the Lysogenic cycle? Justify your answer.
Answer:
Explanation:
It would be more difficult to get rid of a virus using the Lysogenic cycle compared to the Lytic cycle. The Lysogenic cycle involves the virus integrating its genetic material into the host cell's DNA, making it a part of the host's genome. This makes it more challenging to eliminate the virus as it is protected by the host's cellular machinery and cannot be targeted by traditional antiviral drugs. On the other hand, the Lytic cycle involves the virus replicating and then lysing the host cell, which makes it easier to target the virus and remove it using antiviral medications.
