Answer:
There are different types of science according to their main goals. The goal of basic science is to increase our understanding of general principles.
Option d.
Types of science/research
Basic science
⇒ It is directed to understand fundamental problems or issues.
⇒ It is about generating basic knowledge.
⇒ It constitutes the theoretical basis of knowledge on which applied science or technology is based.
Applied science
⇒ It makes use of the knowledge generated by basic science to solve practical problems.
⇒ It generates knowledge that has a practical use.
Technological development
⇒ It is one of the main tools of science.
⇒ Its main function is to create useful tools and artifacts to facilitate the scientist's work.
The goal of basic science is to increase our understanding of general principles.
Option d.
Answer:
<em>- Galileo used a telescope to study the moons orbiting Jupiter. This showed that Earth was not the center of all things.</em>
<em>-Galileo discovered the phases of Venus, proving that at least one planet orbited the Sun.</em>
Explanation:
Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Beginning on January 7, 1610, he mapped nightly the position of the 4 “Medicean stars” (later renamed the Galilean moons). Over time Galileo deduced that the “stars” were in fact moons in orbit around Jupiter.
At about the same time, German mathematician Johannes Kepler was publishing a series of laws that describe the orbits of the planets around the Sun. Still in use today, the mathematical equations provided accurate predictions of the planets’ movement under Copernican theory. In 1687, Isaac Newton put the final nail in the coffin for the Aristotelian, geocentric view of the Universe. Building on Kepler’s laws, Newton explained why the planets moved as they did around the Sun and he gave the force that kept them in check a name: gravity.

Answer:
Because double bonds cause the hydrocarbon chain to bend. Therefore, the fatty acids cannot compact tightly together, reducing the van der Waals interaction between the fatty acids. The melting point of fatty acids is also affected by chain length. The longer the hydrocarbon chain is, the higher the melting point.

Answer:
C) A + T = G + C
Explanation:Erwin Chargaff suggested the rule of the base pairing of DNA structure which is that purine binds pyrimidine or adenine binds thymine and guanine binds cytosine.
The composition of adenine and thymine and guanine and cytosine equals 100 percent.
In the given question, since option C shows that A binds T and G binds C and their composition equals 100%, therefore, Option-C is the correct answer.
Thus, Option-C is the correct answer.
Answer: Option D
Explanation:
The bacterium which is known as flesh eating bacterium is known as Streptococcus pyrogenes.
The disease caused by this bacterium is an infection in which one or more than one bacterium is used to describe this disease.
This bacterium releases toxin that destroys tissues inside the body such as skin, fat, mucous.
This disease is known necrotizing fasciitis. Hence, the correct answer is Option D.
