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.
My guess would be A. B isnt right because you dont need a whole organ to grow an organ, but just a few of its cells. C isnt good either because you can control what stem cells will develop into by taking a cell from whatever is need, and d just doesnt make sense to me.
Answer:
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.

im pretty sure that is tropism. im pretty sureeeee
Answer:
b. Increased activity of GABA neurons is the correct answer.
Explanation:
The ultimate result of benzodiazepines in the brain is it Increased activity of GABA neurons.
Benzodiazepines work by enhancing the impact of a brain chemical called gamma-aminobutyric acid.
Benzodiazepines work by reducing the nerve activity within the brain and rest of a central nervous system.
When GABA attach to a protein present in your brain called GABA receptor it produces a calming effect and it helps with a feeling of stress, fear, and anxiety and also prevents seizures.
