Woah where do i start well first earthquakes are movements of tectonic plates under the crust when they slide together they make vibrations wich is what we feel but they happen mostly on fault lines places like San Andreas are on those lines so they feel them most. fault lines are the place where 2 continents meet as they drift and move on liquid magma under them they crash into each other.
Primary succession is a method of fertilizing soil that was barren and had never supported plant life, for example soil left over by a moved glacier of lava.
Answer:
both ions are transported actively
Explanation:
If both ions are being transported against their concentration gradients, then they are both being transported by active transport, as it requires energy.
A co-transporter moves two substances across the membrane, one passively and one actively. But in this case neither ion is moved passively, so it cannot be considered a cotransporter
The pattern of the flow of energy in the ecosystem take place in an unidirectional pattern. In the ecosystem, unidirectional pattern of energy flow should be present, following the law of thermodynamics which states that the amount of energy in the universe is constant. It cannot be created or destroyed, however, it may be changed into another form of energy. Example: chemical to heat. The law also says that without degradation into heat energy, non-random energies like mechanical, chemical or radiant energy cannot be changed.
Question: Jezelyn needs to create a project that shows reproductive isolation in action and decides to make a video. Which of the following would make the best project?
a video that shows a large river that has penguin populations on both sides
a video that shows penguin species that have different mating dances a video that shows
a penguin that is laying eggs a video that shows penguins in a tidal pool and an open ocean
Answer:
The right option is a video that shows penguin species that have different mating dances.
Explanation:
Reproductive isolation is the inability of animals of closely-related species to interbreed with one another successfully as a result of various differences which can be ecological, behavioral, psychological, or genetic. From the question given above, the difference in the mating dances of the penguin species will not allow the animals to unite and mate. This condition describes reproductive isolation. Reproductive isolation is caused by mating differences, sterility or environmental barriers that eventually lead to the adaptive splitting into two species. However, reproductive isolation is not sufficient but internal barriers to gene flow are required for speciation to evolve.
