<h2 /><h2> $Answer-$ </h2>

The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory (1991–2000), the Chandra X-ray Observatory (1999–present), and the Spitzer Space Telescope (2003–2020). The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft.

Answer:

1. False

2. Biuret's test

3. No test will be used

4. Proteins

5. Lugol's reagent

Explanation:

1. Benedict's test is used to detect carbohydrates. Specifically, it tests for the presence of simple carbohydrates, such as monosaccharides and disacchsrides. It is blue in the absence of sugar, green/yellow in the presence of a small amount of sugar, orange red in the presence of a moderate amount of sugars, and brick red when there are lots of sugars present.

2. Biuret's reagent is a chemical test that measures the presence of proteins by detecting the presence of a peptide bond. The test is used to measure the concentration of proteins in a sample. The intensity of the purple colour formed is directly proportional to the concentration of protein present.

3. Nucleic acids are not detected by any of the listed tests. Biuret reagent tests for the presence of proteins, Benedict's reagent detects the presence of carbohydrates. The beta carotene test measures the level of beta-carotene in the blood. diphenylamine can be used as a colorimetric test for the presence of DNA or RNA.

4. Enzymes are a class of proteins. They are biological catalysts, meaning they participate in, and speed up, chemical reactions in the cell, without us themselves becoming altered in the reaction. They are proteins, and thus formed from chains of amino acids.

5. Lugol's reagent, also called Lugol's iodine, is a strong iodine solution that detects the presence of starch (turning a dark blue/black colour). This means it will not detect the presence of glucose, as this is monosaccharide rather than a polysaccharide like starch

How do waterfalls form?

jarptica [38.1K]

Answer:

Soft rock erodes

Explanation:

Often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls.
