Q: What have approximately the same mass as protons but no charge? Read this paragraph and choose the correct option from the provided answers: Neutrons have approximately the same mass as protons but no charge. They are electrically neutral. The mass of a proton or a neutron is about 1836 times greater than the mass of an electron. Protons and neutrons constitute by far the bulk of the mass of atoms. The discovery of the electron and the proton was crucial to the development of the modern model of the atom and provides an excellent case study in the application of the scientific method. In fact, the elucidation of the atom's structure is one of the greatest detective stories in the history of science. Choices: - atoms - reactions - electrons - neutrons A:
neutrons

Q: What is the most numerous species on the planet? Read this paragraph and choose the correct option from the provided answers: Practically all surfaces. Bacteria can live and grow in practically any environment. It is this ability that has made bacteria the most numerous species on the planet. Choices: - trees - viruses - humans - bacteria A:
(Answer)
bacteria

Ques: Q: Compounds that form from two or more nonmetallic elements are called what? Read this paragraph and choose the correct option from the provided answers: Compounds that form from two or more nonmetallic elements, such as carbon and hydrogen, are called covalent compounds . In a covalent compound, atoms of the different elements are held together in molecules by covalent bonds. These are chemical bonds in which atoms share valence electrons. The force of attraction between the shared electrons and the positive nuclei of both atoms holds the atoms together in the molecule. A molecule is the smallest particle of a covalent compound that still has the properties of the compound. Choices: - ionic bonds - valent bonds - hydrogen bonds - covalent bonds A:
Ans: covalent bonds

(A).
apical meristem

Ques:Q: Which system consists of all the bones of the body? Read this paragraph and choose the correct option from the provided answers: The skeletal system consists of all the bones of the body. How important are your bones?. Choices: - circulatory system - nervous system - digestive system - skeletal system A:

Ans:skeletal system

Q: A spontaneous change process called neutrino oscillations can occur only if neutrinos have what property? Read this paragraph and choose the correct option from the provided answers: that the weak interaction could change quark flavor. It should also change neutrino flavorthat is, any type of neutrino could change spontaneously into any other, a process called neutrino oscillations. However, this can occur only if neutrinos have a mass. Why? Crudely, because if neutrinos are massless, they must travel at the speed of light and time will not pass for them, so that they cannot change without an interaction. In 1999, results began to be published containing convincing evidence that neutrino oscillations do occur. Using the Super-Kamiokande detector in Japan, the oscillations have been observed and are being verified and further explored at present at the same facility and others. Neutrino oscillations may also explain the low number of observed solar neutrinos. Detectors for observing solar neutrinos are specifically designed to detect electron neutrinos e produced in huge numbers by fusion in the Sun. A large fraction of electron neutrinos. Choices: - velocity - temperature - color - mass A:
mass
