Answer the following question given this paragraph: Figure 30.4 Leaves are attached to the plant stem at areas called nodes. An internode is the stem region between two nodes. The petiole is the stalk connecting the leaf to the stem. The leaves just above the nodes arose from axillary buds. Q: What is the term for the stalk connecting a leaf to a stem? Choices: - cuticle - blades - base - petiole A:
petiole

Answer the following question given this paragraph: The sunlight that reaches Earth is the planet's most important source of energy. The energy in sunlight, called solar energy, is electromagnetic energy. This is a form of energy that travels through space in electric and magnetic waves. Solar energy can be used to heat homes and produce electricity in solar cells like those on the roof seen in the Figure below . Sunny areas receive plenty of sunlight to generate electricity, but solar energy may not be practical in areas that are often cloudy. Q: What is the most important source of energy on earth? Choices: - the earth's core - water - moon - sun A:
(Answer)
sun
Ques: Answer the following question given this paragraph: 4.2 Newton's First Law of Motion: Inertia Newton's first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion. Inertia is related to an object's mass. Mass is the quantity of matter in a substance. Q: What is the tendency of an object to remain at rest or remain in motion called? Choices: - impetus - magnetism - flow - inertia A:
Ans: inertia
(Q).

(A).
energy
Ques:Answer the following question given this paragraph: Ribosomes are structures in the cytoplasm where proteins are made. Q: What are the structures in the cytoplasm where proteins are made? Choices: - nucleus - chromosomes - prokaryotes - ribosomes A:

Ans:ribosomes
Answer the following question given this paragraph: The frequency factor is used to convert concentrations to collisions per second. Equation 14.39 is known as the Arrhenius equation and summarizes the collision model of chemical kinetics, where T is the absolute temperature (in K) and R is the ideal gas constant [8.314 J/(Kmol)]. Ea indicates the sensitivity of the reaction to changes in temperature. The reaction rate with a large Ea increases rapidly with increasing temperature, whereas the reaction rate with a smaller Ea increases much more slowly with increasing temperature. If we know the reaction rate at various temperatures, we can use the Arrhenius equation to calculate the activation energy. Taking the natural logarithm of both sides ofEquation 14.39, Equation 14.40. Q: What is used to convert concentrations to collisions per second? Choices: - speeds factor - collision meter - particles factor - frequency factor A:
frequency factor
