Answer the following question given this paragraph: The majority of arthropods are insects (Class Insecta). In fact, more than half of all known organisms are insects. There may be more than 10 million insect species in the world, although most of them have not yet been identified. In terms of their numbers and diversity, insects clearly are the dominant animals in the world. Q: More than half of all known organisms are what? Choices: - mammals - enzymes - spiders - insects A:
insects

Answer the following question given this paragraph: Figure 9.28 Diffusion occurs when gas molecules disperse throughout a container. Effusion occurs when a gas passes through an opening that is smaller than the mean free path of the particles, that is, the average distance traveled between collisions. Effectively, this means that only one particle passes through at a time. Q: What occurs when a gas passes through an opening that is smaller than the mean free path of the particles? Choices: - precipitation - malformation - dissipation - effusion A:
(Answer)
effusion
Ques: Answer the following question given this paragraph: 33.2 The Four Basic Forces The four basic forces and their carrier particles are summarized in the Table 33.1. Feynman diagrams are graphs of time versus position and are highly useful pictorial representations of particle processes. The theory of electromagnetism on the particle scale is called quantum electrodynamics (QED). Q: What do we call the theory of electromagnetism on the particle scale? Choices: - iron electrodynamics - light electrodynamics - gravity electrodynamics - quantum electrodynamics A:
Ans: quantum electrodynamics
(Q).
Answer the following question given this paragraph: Q: Hormones vary widely in molecular size and type as well as? Choices: - simple regulators - strange regulators - foreign regulators - local regulators A:
(A).
local regulators
Ques:Answer the following question given this paragraph: A: The main ingredient of mothballs is the hydrocarbon naphthalene. The main ingredient in nail polish remover is the hydrocarbon acetone. The lawn mower runs on a mixture of hydrocarbons called gasoline, and the camp stove burns a hydrocarbon fuel named isobutane. Q: What is the main ingredient of mothballs? Choices: - stable naphthalene - processed naphthalene - ionized naphthalene - hydrocarbon naphthalene A:

Ans:hydrocarbon naphthalene
Answer the following question given this paragraph: The answer is actually "no. " A virus is essentially DNA or RNA surrounded by a coat of protein ( Figure below ). It is not made of a cell , and cannot maintain a stable internal environment ( homeostasis ). Recall that a cell is the basic unit of living organisms. So if a virus is not made of at least one cell, can it be living? Viruses also cannot reproduce on their ownthey need to infect a host cell to reproduce. So a virus is very different from any of the organisms that fall into the three domains of life. Q: A virus is essentially dna or rna surrounded by a coat of what? Choices: - acids - paint - organism - protein A:
protein
