Q: In what two ways are volcanic eruptions characterized? Choices: - minor and explosive - localized and general - non-explosive and serious - explosive and non-explosive A:
explosive and non-explosive

Answer the following question given this paragraph: Saturated hydrocarbons are hydrocarbons that contain only single bonds between carbon atoms. They are the simplest class of hydrocarbons. They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogen. You can see an example of a saturated hydrocarbon in the Figure below . In this compound, named ethane, each carbon atom is bonded to three hydrogen atoms. In the structural formula, each dash (-) represents a single covalent bond, in which two atoms share one pair of valence electrons. Q: What are hydrocarbons that contain only single bonds between carbon atoms called? Choices: - caloric hydrocarbons - unsaturated hydrocarbons - carcinogenic hydrocarbons - saturated hydrocarbons A:
(Answer)
saturated hydrocarbons

Q: What is the multi-phase process in which the nucleus of a eukaryotic cell divides? Choices: - fission - Osmosis - cytokinesis - mitosis A:
Ans: mitosis
(Q).
Answer the following question given this paragraph: Q: What are the two ways animals can manage their internal environment? Choices: - digestion or excretion - sweating or sleeping - adaptation or mutation - regulating or conforming A:
(A).
regulating or conforming
Ques:Answer the following question given this paragraph: In Silver Springs, the TLTE between the first two trophic levels was approximately 14.8 percent. The low efficiency of energy transfer between trophic levels is usually the major factor that limits the length of food chains observed in a food web. The fact is, after four to six energy transfers, there is not enough energy left to support another trophic level. In the Lake Ontario example shown in Figure 46.6, only three energy transfers occurred between the primary producer, (green algae), and the apex consumer (Chinook salmon). Ecologists have many different methods of measuring energy transfers within ecosystems. Some transfers are easier or more difficult to measure depending on the complexity of the ecosystem and how much access scientists have to observe the ecosystem. In other words, some ecosystems are more difficult to study than others, and sometimes the quantification of energy transfers has to be estimated. Another main parameter that is important in characterizing energy flow within an ecosystem is the net production efficiency. Net production efficiency (NPE) allows ecologists to quantify how efficiently organisms of a particular trophic level incorporate the energy they receive into biomass; it is calculated using the following formula:. Q: Net production efficiency allows ecologists to quantify how efficiently organisms of a particular what incorporate the energy they receive into biomass? Choices: - hypothesized level - neural level - sea level - trophic level A:

Ans:trophic level
Ques: Answer the following question given this paragraph: Sedimentary rocks are formed in horizontal layers. This is magnificently displayed around the southwestern United States. The arid climate allows rock layers to be well exposed ( Figure below ). The lowest layers are the oldest and the higher layers are younger. Q: Sedimentary rocks form in what kind of layers? Choices: - stacked - magnetic - vertical - horizontal A:
Ans:
horizontal
