Answer the following question given this paragraph: Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall. There is also a wide range of skin color across people. Skin color is also a polygenic trait, as are hair and eye color. Q: What is the term for traits that show wide variation, such as height, skin color, and eye color? Choices: - maladaptive traits - inherited traits - recessive traits - polygenic traits A:
polygenic traits

(Answer)
stem
Ques: Answer the following question given this paragraph: For many decades, scientists have known that atoms consist of electrons and other particles called protons and neutrons. Recently they found that there are even smaller particles in atoms. Scientists call these extremely tiny particles by the funny name of quarks. As you can see in this diagram, there are several different kinds of quarks, called up quarks, down quarks, top quarks, bottom quarks, charm quarks, and strange quarks. In this chapter you'll learn about these unusual particles and also other particles inside the atom. Q: For many decades, scientists have known that atoms consist of electrons and other particles called protons and? Choices: - rods - waves - nanoparticles - neutrons A:
Ans: neutrons
(Q).
Answer the following question given this paragraph: Not every neutron produced by fission induces fission. Some neutrons escape the fissionable material, while others interact with a nucleus without making it fission. We can enhance the number of fissions produced by neutrons by having a large amount of fissionable material. The minimum amount necessary for self-sustained fission of a given nuclide is called its critical mass. Q: The minimum amount necessary for self-sustained fission of a given nuclide is called what? Choices: - its half-life - its molar mass - its activation energy - its critical mass A:
(A).
its critical mass
Ques:Answer the following question given this paragraph: Sexual reproduction involves two parents. It produces offspring that are all genetically unique. It requires the production of haploid gametes. The union of gametes is called fertilization. It results in a diploid zygote. Q: The union of gametes is called? Choices: - pollination - migration - fusion - fertilization A:

Ans:fertilization
Answer the following question given this paragraph: Compared to Earth, the solar system is a big place. Compared to the solar system a star cluster is a big place. But galaxies are biggera lot bigger. Q: Which of these is last if ordered in increasing size: galaxy, solar system, star cluster? Choices: - none of these - solar system - star cluster - galaxy A:
galaxy
