Pneumococcus of type IIIS (virulent) is killed by heating the mixture, which is subsequently homogenized and the bacteria are subsequently injected into living mice.
When the IIIS bacteria are treated with DNase and heated to death. DNA will then breakdown as a result of DNase. The living IIR bacteria cannot undergo any changes or transformations as a result of this DNA. Mice won't perish. Because DNA is the transforming principle and the DNase degrades DNA, this occurs. DNA is responsible for turning virulent organisms into non-virulent ones.Any infection brought on by the pneumococcus, also known as Streptococcus pneumoniae, is known as pneumococcal disease (noo-muh-KOK-uhl). Ear, sinus, and bloodstream infections can all be caused by pneumococcal infections, as well as pneumonia.Of healthy individuals, 5 to 90% may have the bacteria in their nasopharynx.To know more about virulent here

More energy can be from fat molecule than from glucose molecule because the fat molecule contains more
Answer: Hope this helps.
Explanation: Triglycerides store about twice as much energy as carbohydrates. Triglycerides are made of glycerol and three fatty acids. Because there are so many carbons in three fatty acids, and each 2-carbon unit can enter the citric acid cycle, one fatty acid molecule can generate much more ATP than one molecule of glucose.
Answer:
because the fat molecule contains more kilocalories per gram
s a researcher in a protein lab, you analyze two different proteins for their shape and the amino acids they contain. your results show that the two proteins have exactly the same numbers and types of amino acids, but they have different shapes.
According to the given statement Each protein has a unique linear sequence of amino acids.
What are amino acids ?Amino acids are the building blocks of proteins. Life's essential building blocks are proteins and amino acids. The breakdown or digestion of proteins produces amino acids as waste products. The human body uses amino acids to make proteins that help with food dissection.
Where can you find amino acids in the body?Three amino acids—valine, leucine, and isoleucine—known as branched-chain amino acids (BCAAs) have a branching chemical structure. A common component of muscle proteins, BCAAs promote the body's natural process of muscular growth and give us energy while we exercise.

“Why is there so much peat in the peat/perfrost system? Minimum of 5 sentences
PLEASE HELP
There is so much peat in the peat /perfrost system as a result of the low oxygen concentration in the environment which leads to incomplete decomposition occurring.
What is a Peat?This substance has a soft and dark brown property and is formed from partially decaying organic matter and dead substances present in a long period of time.This could take a certain period of years and are also rich in carbon content.
Perma frost is referred to an area which is located on land or under the ocean in areas where there is a low concentration of oxygen as result of certain factors and properties.
Since we are aware that peat is formed partially decaying organic matter under low oxygen concentration, then it is therefore the reason why there is so much peat in the peat/perfrost system and is therefore the correct choice.

Why do scientists think gases such as CO2 trap heat in the atmosphere?
Greenhouse gases are more complex than other gas molecules in the atmosphere, with a structure that can trap heat. Greenhouse gas molecules in the atmosphere absorb light, preventing some of it from escaping the Earth.
Carbon dioxide is Earth's most important greenhouse gas that works for absorbing and radiating heat. Greenhouse gases absorb heat radiating from the Earth's surface and even circulate it in all directions including back toward Earth's surface.
Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere's carbon dioxide content by 50% in less than 200 years.

The responsibility to preserve and protect the environment is known as ecological responsibility. The majority of the time, ecological responsibility is related to businesses making sure that their operations always abide by environmental laws and regulations.
Explain about vegetarian diet is more Ecologically responsible?People can drastically minimize their consumption of land, water, and oil resources as well as the amount of pollution they might otherwise generate by selecting a vegetarian diet rather than one high in animal products.But when the study's 153 vegans, vegetarians, and omnivores were all included in, it became clear that eating meat was, on average, worse for the environment. When we think about food crops, there are other broad issues to keep in mind that could have a greater negative influence on the ecosystem.According to a thorough peer assessment of studies on vegetarianism, a non-meat diet will probably result in a person emitting less carbon dioxide than they would with a meat-based diet—roughly 1,200 pounds less carbon dioxide. That translates to a mere 4.3% reduction in emissions for the average person living in industrialized nations.

Earth's last sink for plastic waste, the oceans, receive the majority of it from the land. Major rivers operate as conveyor belts, gathering up debris as they flow downstream and carrying it to the ocean. Many pieces of plastic waste that are floating at sea stay in coastal waters.
Why is plastic in the ocean happening?Plastic garbage is transported through drains, streams, and rivers by wind and rain. Ocean access is via drains! Another significant factor is careless and incorrect garbage disposal; unlawful rubbish dumping significantly contributes to the plastic pollution of our oceans.Being such a persistent contaminant, plastic waste is particularly harmful. Decomposition of plastic products might take hundreds of years. Both people and animals are at risk from this garbage.

The organelle is common to many types of cells and is the primary site for storage of materials such as water, proteins, lipids, and cellular waste. The size of the organelle can vary between plants and animals depending on its general function. True or false?.
Answer:
I believe its True
The organelle is common to many types of cells and is the primary site for storage of materials such as water, proteins, lipids, and cellular waste. The size of the organelle can vary, and it is a vacuole. This is the true explanation.
What are the different functions of the cell organelles?The cell organelles are different in different organisms, such as plants, animals, yeast, etc., because the cell organelles and their functions vary too. The plant cell has a large vacuole, which contains water, proteins, lipids, cellular waste, etc., it has mitochondria, a nucleus, etc., and the function of the vacuole is different from that of the animal cell vacuole. The vacuole of the plant cell is larger than that of the animal cell because the plant cell vacuole maintains the water pressure, but the animal cell does not do this.

This is a unique research program developed by Carl Woese, it is based on rRNA, for discerning bacterial relationships and constructing a universal tree of life. Woese's interest in the evolution of the genetic code led to him to investigate the deep roots of evolution, develop the concept of the progenote, and conceive of the Archaea.
