Answer the following question given this paragraph: Colonial organisms were probably one of the first evolutionary steps towards multicellular organisms. Algae of the genus Volvox are an example of the bridge between colonial organisms and multicellular organisms. Each Volvox , shown in Figure above , is a colonial organism. It is made of up to 50,000 photosynthetic flagellate algae that are grouped together into a hollow sphere. Volvox live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700. Q: Colonial organisms were probably one of the first evolutionary steps towards which type of organisms? Choices: - double cellular - mutated - fetus - multicellular A:
multicellular

Answer the following question given this paragraph: The energy of electromagnetic waves depends on their frequency. Low-frequency waves have little energy and are normally harmless. High-frequency waves have a lot of energy and are potentially very harmful. Q: Which form of electromagnetic waves have more energy: low frequency wave or high frequency waves? Choices: - neither - low frequency waves - the same - high frequency waves A:
(Answer)
high frequency waves

(Q).
Answer the following question given this paragraph: A variable is a factor that can change over the course of an experiment. Independent variables are factors whose values are controlled by the experimenter to determine its relationship to an observed phenomenon (the dependent variable). Dependent variables change in response to the independent variable. Q: The values of which factors are controlled by the experimenter over the course of an experiment? Choices: - other variables - independent elements - independent approaches - independent variables A:
(A).
independent variables
Ques:Answer the following question given this paragraph: Electromagnetic waves vary in their frequencies and wavelengths, and waves with higher frequencies have greater energy. The electromagnetic spectrum represents the full range of frequencies of electromagnetic waves. Q: The electromagnetic spectrum represents the full range of frequency of what type of wave? Choices: - transverse wave - mechanical - seismic - electromagnetic A:

Ans:electromagnetic
