Wavelength light source is part of the control group for William’s experiment
<u>Explanation:</u>
Sir William wanted to conduct an experiment to observe how much heat passed through different colour filters of the sunlight. He directed sunlight to pass through the prism and observed vibgyor and measured the temperature. He found that the temperature increased from violet to red.
Then he was inquisitive to find the temperature beyond the red ray. That’s when he found the infrared rays which had higher temperature that was not to be seen through naked eyes. He performed experiments using the light source and found that the wavelength of light are not refracted in a particular pattern.
15)C
16)D because the function of mitochondria is providing energy
17)B cell wall
18)C cell membrane
19)C plantae
20)B cytoplasm
Answer:
<em>The correct option is C) Mitochondrial DNA can be traced for generations.</em>
Explanation:
The mitochondria are the organelles of the animal cell which contain their own genome. This genome also has the ability to produce proteins. The mitochondrial DNA passes from the mother to the children and remains identical. We can say that the mother and the children will possess the same mitochondrial DNA. In this manner, the mitochondrial DNA can be traced for generations as it remains the same for generations.
Answer:
cell membrane
Explanation:
Single cell organisms like the bacteria depend mostly on diffusion for gaseous exchange. They take in food that does not require complex digestion processes. The cell membrane is selectively permeable and allows absorption of nutrients like glucose that have molecules of small size.
It is a covalent substance because there is a covalent bond between Hydrogen and Oxygen
