Answer:
Experiment to show that sunlight is necessary for photosynthesis - definition. Take a plant with destarched leaf. Leaf is partially covered with black paper on which a design is cut. Expose this plant to sunlight for few hours and perform a starch test with iodine solution.

Answer:
It occurs to create innovation in the existing technology.
Explanation:
A technological advancement is an attempt to develop current materials, devices, products or processes by further understanding of science. technological advancement provides innovations of existing technology or formation of new technology in order to better the life style and make easier our work. If the technological advancement did not occur, we are unable to increase efficiency of various instruments and machines.
These changes are likely genetic mutations
<h2>Further Explanation
</h2>
Evolution is the process of change in all life forms from one generation to the next, and evolutionary biology studies how this evolution takes place. Every generation of organisms inherits traits owned by their parents through genes. <u><em>Changes (called mutations)</em></u> in this gene will produce new traits in the offspring of an organism. In an organism's population, some traits will become more common, while others will disappear. traits that help the survival and reproduction of organisms will be more likely to accumulate in a population than unfavorable traits. This process is called natural selection. The income of more offspring than the number of parents along with the inheritance of these traits is an additional fact about life that supports the scientific basis of natural selection. In a long time, this isolated population will become a new species.

a. What is a star's spectrum?
A star's spectrum refers to the <em>"amount of light"</em> that stars they give off according to varying wavelengths. Since we cannot tell the amount of light a star gives off quantitatively from Earth, we can differentiate them according to how bright they appear.
b. Which spectrum is most common in stars?
Stars are classified according to their spectra <em>(elements in the star)</em>. They are classified into 7 types <em>(O, B, A, F, G, K and O). </em>The most common type is M, however, it gives off a dim light.
c. How can it differ from start to star?
Although stars follow a continuous spectrum, the spectra of a star differs from each other because <u>they do not give off the same amount of energy at the different wavelengths. </u>
d. What does the spectrum tell us about the star?
The spectrum can tell the<em> surface temperature</em> of the star. This means that a blue star (we often see it as a white-colored star from Earth) is hotter than that of a yellow star. A red star is considered the coolest star among all.
The spectrum of stars also allows the astronomers to study composition of the stars according to their <em>wavelengths.</em>
