PLEASE HELP ME Which of the following statements is true? Geographic isolation is the main cause of speciation. Hybrid organisms always produce sterile offspring. If a population is spread out over too large area, they may become extinct. Speciation can only happen when a population has very low genetic diversity. ----- A population of oak trees is separated by a large canyon. Which of the following is most likely to occur? The two populations will show cospeciation. The genetic variation between the two populations will increase. Natural selection will cause one population to die, and the other to live. Both populations will stop evolving. ------- Choose ALL the answers that apply. Extinction: only happens above the species level cannot happen to more than one species at a time can be caused by habitat destruction happens when a species or population dies out ------- Which of the following statements is true? Gene flow evens out genetic differences between populations. Genetic drift increases the genetic differences between populations. Natural selection, mutation, and genetic drift are random events.

Explain the effect on the internal energy of the water and the movement of water molecules

Answers

Answer:

Its kinetic energy increases

Explanation:

Its molecules move very faster and some atoms go through ionization because the collision of the atoms because their increase in movement speed and intensity. Ionization is the loss or gain of electrons, which are around the nucleus of atoms. Since equals charges repeal and electrons have negative charges, they move from their levels of energy during collisions. Its conductivity can also become lower, because the flow of electrons can be interrupted by the violent movement of the molecules.

Compare the processes of anaerobic respiration in muscle and plant cells

Answers

Anaerobic respiration is different in plants and animals:

Anaerobic respiration occurs when oxygen is not available and occurs differently in animal and plant cells. In animal cells anaerobic respiration often occurs during exercise. ... It still occurs without oxygen but the glucose molecule is broken down into ethanol, carbon dioxide and a small amount of energy.

Which factor does not play a role in runoffthe amount of rain or snow



plants



gravity



solar radiation

Answers

Infiltration is the process by which rainwater becomes groundwater. In the water cycle, which involves primarily; evaporation, condensation and precipitation. Henceforth, after precipitation comes infiltration in the land areas leaving the rainwater aggregated in a single location which accumulates over time. Then this process is followed by runoff and subsurface flow by which water flows through other bodies of water, either in river, sea or ocean, even lake. Other rainwaters that has segregated and wasn’t able to transport itself stays in the process of infiltration, thus groundwater.

Thus, solar radiation doesn't play a role in runoff or infiltration.
