Too much food, such as a meal or snack with more carbohydrates than usual.
Answer:
A positive result.
Explanation:
Biuret test is a test performed to check whether proteins are present in a given sample or not. If the solution changes its colour to violet then it means that the sample contains proteins. If the colour is not changed to violet, then the result would be negative and protein would not be present in the sample.
Steaks contain a rich amount of protein. Hence, when Biuret test is performed for a steak solution, the results will be positive. The steak sample would change colour to violet.
Answer:
A
Explanation:
All living organisms ranging from unicellular prokaryotes to multicellular eukaryotes contain genetic material (DNA). This genetic material is usually found on structures called CHROMOSOMES. Although, the chromosomes are contained in the genome of all living organisms, there are differences.
The genetic material of the bacteria (a typical prokaryote) is a single DNA molecule that makes up its single circular chromosomal material, unlike in eukaryotes that contains double-stranded DNA molecules on linear chromosomes. This single circular chromosome of bacteria is found naked in a region of their cell called NUCLEOID, as they do not possess a membrane-bound nucleus that houses it (a unique characteristics of eukaryotes).
The mitochondrial and Chloroplast DNA mentioned in the other options are all components of eukaryotic cells. Bacteria, as a prokaryote does not contain this organnelles. Hence, they are not single replica.
Answer:
The primary function of mucus in the stomach is <u>protect the stomach cells from gastric juices (e.g., HCl).</u>
Explanation:
The stomach is an important organ in the process of digestion, it performs a variety of functions that include the storage and exposure of food to the acid it secretes, in addition to providing a barrier that prevents the passage of microorganisms to the intestine. The gastric mucosa protects the stomach from digestion caused by acid gastric juices in which the superficial cells of the mucosa would produce a mucous layer, which would leave the stomach completely unprotected. The stomach creates gastric acids to break down food. These acids, also called gastric juices, are very strong acids found in the stomach. Its function is to promote the digestion of proteins that come from the products we eat. The components of gastric juices are produced by the gastric glands found in small cavities of the gastric mucosa. The gastric glands are elongated and consist of several types of cells: superficial cells, main cells and parietal cells. Superficial cells produce mucus that protects the stomach from attack by digestive acids and enzymes.
Photosynthesis makes the glucose that is used in cellular respiration to make ATP<span>. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water</span>
