Read the following scenario to answer this question:[/HTML]Mike loves to cook. He heard that if you add salt to water, it will boil faster. If it’s true, it could save him a lot of time in the kitchen. He decided to perform an experiment to test this hypothesis. He set up three pots, each containing three liters of water. In the first pot, he didn’t add any salt; in the second pot, he added one tablespoon of salt; and in the third pot, he added two tablespoons of salt. He got out his stop watch and turned the stove on under all three of the pots.Is there a control group, and if so, what is it? ____________________

Answer:

Describing a trait as dominant does not mean it is the most common; it means that it is expressed over the recessive trait. For example, tongue rolling is a dominant trait, controlled by the dominant version of a particular gene (R). Individuals with one or two copies of R will exhibit tongue rolling.

Nitrogenous bases basically pairs with bases that are complementary. The correct option is B.

Nucleobases, also referred to as nitrogenous bases or purely bases, are nitrogen-containing biological molecules that form nucleosides, which are then constituents of nucleotides, all of which are the basic building boxes of nucleic acids.

A set of 5 nitrogenous bases is used to build nucleotides, which then in results nucleic acids such as DNA and RNA.

These bases are critical because their sequencing in DNA and RNA is how information is stored.

A base pair in DNA are complementary to each other. Under normal conditions, the nitrogen-containing bases adenine (A) and thymine (T) pair, whilst also cytosine (C) and guanine (G) pair.

The structure of DNA is formed by the binding of these base pairs.

Thus, the correct option is B.

Answer:

What did researchers learn from terra preta?...  Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.

How is bio-char different from the traditional Amazonian method of creating terra preta?  Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..  

The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.

Terra preta is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Researchers have learned from terra preta that it contains a high level of carbon, along with nutrients such as nitrogen, phosphorus, and potassium.

Terra preta, or "black earth," is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Scientists have studied terra preta to understand its unique properties and how it was created. Terra preta is a type of anthropogenic soil, which means that it was created by human activity rather than natural processes. It is believed that the indigenous people of the Amazon region created terra preta by adding biochar to soil along with other organic materials such as bones, shells, and manure.

Hence, researchers have learned from terra preta that it contains a high level of carbon along with nutrients such as nitrogen, phosphorus, and potassium.

Nitrate plays very vital role in our ecosystem and such that due to presence of the nitrogen plants grow rapidly as well as it produces bigger size fruits and flowers. Plants absorb nitrates in water through their roots without nitrates, the amount of the chlorophyll in leaves reduces.

Nitrate has been a common inorganic ion found in plants that has required for proper growth and development. Many growers has been included the addition of the nitrates in their nutrient regiment to the stimulate plant growth. Plants has been acquire nitrate through the root intake from the soil and water around them.

Phosphorus has a limiting growth factor in the terrestrial ecosystems because the quantity of phosphorus in soil are generally small it has been often the limiting factor for plant growth.

Answer:

Metaphase

Explanation:

The answer is metaphase.

DNA helicase is the enzyme that breaks the hydrogen bonds which holds the two DNA strands together during DNA replication.

During replication of DNA , the enzyme DNA helicase separates the two strands of DNA and causes the breakdown of hydrogen bonds between the two DNA strands which leads to separating of the DNA double helix into two individual strands which make easier to copy it.

In conclusion, DNA helicase is the enzyme that breaks the hydrogen bonds.
