Answer:
<em>I'm not positive on this but </em><u><em>point mutation</em></u><em> and</em><u><em> insertion.</em></u>
Explanation:
Answer:
The correct answer is 8 g.
Explanation:
During a physical change, the identity of the substance <u>does not change, because no chemical reaction occurs</u>. So, after the change, the amount of substance is still the same. Examples of physical changes are changes in the state of matter (solid-liquid-gas). If 8 grams of ice (water in the solid-state) are melted, after the melting process we will have 8 grams of water in the liquid-state, but still 8 grams of water.
Answer:
Dry air.
Explanation:
One definition of dry air is a theoretical sample of air that has no water vapor. Another definition of dry air is air that has a low relative humidity. When the relative humidity drops below about 40%, the air feels dry to the skin.
Answer:
Force of repulsion.
By decreasing distance and increasing charge on both objects.
Explanation:
Force of repulsion is present between two negatively charged objects due to their same charge. if both charges are opposite to one another so it exerts force of attraction on one another. If we decrease the distance between two negatively charged objects so they exerts more force of repulsion on one another or by increasing power of charge on both objects also increases force on one another.
Answer:
D. physiological mechanisms are the basis of behaviors.
Explanation:
The example of the development of electric fields as part of the communication between some fish, shows the interrelation that exists between physiology and behavior. This physiological factor that fish have has an impact on their behavior. However, it is necessary to recognize that physiology does not act by itself, but needs to receive a stimulus from the surrounding environment.
This way of communicating is called electrocommunication, a fish generates through its physiology an electric field and a second individual receives that electric field with its electroreceptors.
