Ans.

Gene are considered as fundamental units of DNA. The similarity in DNA sequences of different organisms reflect a common ancestry, which appears to be shared by all organisms present on earth.

Human DNA shows very less similarity with weeds' (plants) DNA, which is around 18%. Thus, plants show different metabolic functions from humans, such as photosynthesis.

Human DNA shows around 26% similarity with yeast (fungus) DNA, as yeasts have some housekeeping genes, same as genes present in humans. For example, genes to uptake energy from sugar breakdown.

Human DNA shows 44 % similarity with fruit fly (insect) DNA. Mammals, such as humans and insects share genes, which are responsible for their growth and structures.

Human DNA shows 92 % similarity with DNA of mouse as they both are mammals and share many common genes.

Human DNA shows 98 % similarity with DNA of chimpanzee. That is why, chimpanzees are considered as closest relative of humans.

To understand the chemical basis of inheritance, we must understand the molecular structure of DNA.

Answer:

C) reductionism

Explanation:

The approach of reductionism is applied to decipher the basic concepts that rule some complex life processes. In this approach, the complex life processes can be interpreted by explaining the physical and chemical structure of involved components and their interactions. DNA molecules store genetic information. Inheritance means the transfer of genetic traits from one generation to the next. Therefore, the chemical structure of DNA is the application of reductionism to understand the chemical basis of inheritance.

Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of

WARRIOR [948]

Answer:

The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.

Explanation: First we must talk about 3 facts:

1) Prism scatters the white light into different wavelengths.

2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.

6CO2 + 6H2O → C6H12O6 + 6O2

3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.

So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (see figure). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
