Answer the following question given this paragraph: Smooth muscles and cardiac muscles are not attached to bone. Recall that these types of muscles are under involuntary control. Smooth muscle is responsible for the contractility of hollow organs, such as blood vessels, the gastrointestinal tract, the bladder, or the uterus. Like skeletal muscles, smooth muscle fibers do contract together, causing the muscle to shorten. Smooth muscles have numerous functions, including the following. Q: What kind of muscle is responsible for hollow organs contracting? Choices: - micro muscle - tough muscle - rough muscle - smooth muscle A:
smooth muscle

Answer the following question given this paragraph: Atoms form covalent bonds by sharing valence electrons. The valence electrons are located in atomic orbitals. However, when a bond forms, the structure of the atomic orbitals changes. In this lesson, we will see how the atomic orbitals interact to share valence electrons and form different types of covalent bonds. Q: What do atoms form by sharing valence electrons? Choices: - phenotype bonds - neutron bonds - ionic bonds - covalent bonds A:
(A).
covalent bonds
Ques:Answer the following question given this paragraph: Electron affinity is a measure of the energy released when an extra electron is added to an atom. Q: What is the measure of the energy released when an extra electron is added to an atom? Choices: - mass affinity - neutron affinity - volume affinity - electron affinity A:

Ans:electron affinity
Answer the following question given this paragraph: Chromosomal Alterations. Chromosomal alterations are major changes in the genetic material. Q: What term is used to describe major changes in the genetic material? Choices: - generational alterations - eukaryotic alterations - mutational alterations - chromosomal alterations A:
chromosomal alterations
