Answer:
Reducing the amount of light improves contrast, making the specimen "stand out" against the background. Some microscopes have an annular condenser, which is a plate under the stage that can be rotated. The plate consists of holes of different diameter.
Explanation:
The Benedict's solution or the Fehling's solution is a chemical solution with clear blue color, which is a combination of the sodium citrate, sodium carbonate, and cupric sulphate pentahydrate. The Benedict's solution is used to test for the presence of the reducing sugars, such as glucose. When it is added into a solution and warmed, and it changes the color to orange, it confirms the presence of the reducing sugar in the testing solution.
Hence, the maple syrup contains reducing sugar.
Answer:
Charles Robert Darwin was a British naturalist and biologist known for his theory of evolution and his understanding of the process of natural selection
Explanation:
2. <u>Some of these variations are passed on to offspring;</u>
- As the genetic changes may occur due to mutations in the genes.
- As these changes do not occur in days or months but they occur after hundred and thousands of years.
- The off springs are distinct from their ancestors. This results in the formation of new species. Gradual modification of the existing species leading to the formation of new species is known as speciation.
4<u>.Individuals vary in their ability to survive and reproduce</u>;
- Those with the most favorable adaptations are more likely to survive and reproduce.
- Individual variation (usually through mutation) may introduce traits or abilities that enable that individual to survive in order to reproduce. Usually these are tiny incremental changes that accumulate over centuries or millennia.
<u>Note:</u><em> However there are certain drawbacks of Darwinism even such as it failed to explain the basis of variation and the mode of transmission of characters.
