Venus is the second planet from the sun and is the brightest object in the night sky after the Moon. It is often referred to as the Earth's sister planet due to its similar size, mass, and composition. The name Venus is derived from the Roman goddess of love and beauty, Venus.

Venus has been known to humans since ancient times, and it has been revered and revered in many cultures throughout history. In Roman mythology, Venus was the goddess of love, beauty, and fertility.

The Romans named the planet Venus after their goddess because of its bright appearance in the sky. Venus is the brightest planet in the solar system and is often visible in the early morning or late evening hours. It is also known as the "Morning Star" or the "Evening Star" due to its appearance in the sky at different times of the day.

In addition to its bright appearance, Venus is also known for its unique surface features and characteristics. It has a thick, toxic atmosphere made up of mostly carbon dioxide and nitrogen, with clouds of sulfuric acid. Venus also has the hottest surface temperatures of any planet in the solar system, reaching up to 864 degrees Fahrenheit (462 degrees Celsius).

Overall, the name Venus reflects the planet's bright appearance in the sky and its association with the Roman goddess of love and beauty. It is a fitting name for a planet that has captivated and fascinated humans for centuries.

When this procedure happens, the seeds are said to undergo sprouting procedure. L -1 EDTA , a atividade da α-amilase das sementes tratadas com B. Hence, the area of starch agar that represents the absence of starch is bigger and the concentration of brick-red precipitate is lower indicating the presence of small amount glucose. Transfer the seeds including the plumule and radicle into the howitzer. Do not use an Oxford Academic personal account.

Release and activity of bound β-amylase in a germinating barley grain. The seeds were collected at different germination stages 0, 12, 24, 36, 48, 60 and 72 h for determination of α-amylase activity. Hypothesis: The higher the amylase activity, the higher the rate of seed sprouting which is indicated by the higher alterations in length of plumule and radicle. These changes are different from those of germinating seeds of many other plants, but similar to the germinating seeds of alfalfa, which belongs to the same tribe Trifolieae as clover. Then, the supernatant was discarded, and the cells were washed by sterile water three and resuspended in sterile water adjusting to OD 600 of 0.

It indicates that the inhibition has been alleviated. Plant Physiology and Biochemistry, v. Amylase activity is affected by many factors such as temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators. The germination rate was calculated by continuously recording the number of germinated seeds for 72 h. The homogenate was collected in a centrifuge tube and centrifuged for 30 min at 10000 r.
