Answer:
a. is the energy required for molecules to react with each other
Explanation:
Activation energy may be defined as the extra energy required to start a reaction and the conversion of reactants into its products. It is the energy required to energize or activate molecules or atoms to undergo a transformation or a chemical reaction.
It is necessary for all types of chemical reaction to proceed. With the help of a catalyst the reaction rate increases as the energy of activation lower for the reaction to start.
Answer:
the results of the investigation led to new scientific questions
Explanation:
The basis of every scientific question asked is an observation made. Scientific questions are questions that emanate from an observed problem and leads to the formation of a testable explanation (hypothesis). In this question, an investigation was made by a scientist and it was discovered that increased temperature decreases the number of offspring that an organism produces.
However, the scientist asks a new question about the impact of climate change on the species. This is because an observation has been made again, from the previously concluded investigation. Hence, after completing the investigation about the effect of temperature on the number of offsprings an organism can produce, an observation was made, ultimately leading to a new scientific question.
Winds near the surface move across the isobars at an angle when the frictional force, pressure gradient force, and apparent Coriolis force are combined.
<h3>What is the motion of horizontal and vertical air in a high-pressure anticyclone and in a low-pressure cyclone?</h3>
Winds near the surface move across the isobars at an angle when the frictional force is combined with the pressure gradient force and the apparent force of the Coriolis effect. Consequently, the air spirals and converges as it advances in the direction of low pressure. A cyclone sometimes referred to as a low-pressure system, is created by this spiraling inward toward a center of low pressure. Convergence is the technical term for this inward spiraling action, which likewise raises the air at the center.
Air spirals downward and outward from an anticyclone, also known as a high-pressure system, in a high-pressure area. Divergence is the name for this spiraling outward motion. Cyclones rotate anticlockwise in the northern hemisphere and clockwise in the southern hemisphere.
