Answer:
Bases form hydrogen ions (H+) when dissolved in water - False
Bases in chemistry are substances that acquire hydrogen ions or donate the valence electron.
The given statement is False.
Bases are substances when dissolved in water will give hydroxide ions (OH-). For example: Potassium hydroxide(KOH), Sodium hydroxide (NaOH)Acids are substances when dissolved in water will give hydrogen ions (H+) ions. For example: Hydrocholric acid (HCl), Sulfuric acid.Therefore, Bases does not form hydrogen ion when dissolved in water.

How are photosynthesis and cellular respiration related? (A)They are both ways of forming glucose molecules. (B) One forms glucose and the other breaks it down (C)They are both used during fermentation (D)Both processes require an input of sunlight
Answer:
the answer is B
Explanation:
One forms glucose and the other breaks it down.
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.Respiration is the chemical process by which organic compounds release energy.What is energy?
Energy is defined as the ability to do work which for biology purposes, can be thought of as the ability to cause some kind of change.
Energy can take many different forms:
Light EnergyHeat Energy Electrical energy,Mechanical Energy, Electrical Energy,Sound Energy.Hence, B option is correct.

HELP!! How are mid-ocean ridges formed at divergent tectonic plates?
This submarine Mid-ocean Ridge owes its formation to the movement of the continental plates on either side of the ocean. As these plates slowly separate, they leave gaps in the earth's crust. This allows molten rock from beneath the earth's crust to reach the surface, forming a new part of the ocean floor.
Answer:
The stretching lithosphere is pushed up as the plate moves apart
Explanation:
Divergent tectonic plates involves moving apart of tectonic plates. At the divergent boundary plates separate from each other . An example is the oceanic ridge formed in the Atlantic oceanic crust.
The diverging movements of these plates cause magma to be introduce from the oceanic ridge to form a new lithospheric crust. Volcanoes are present in this kind of boundary. The magma may erupt to form volcanoes.
Divergence occurs mainly between oceanic crusts and continental crusts. The moving apart of the plates causes an exposure of the aesthenosphere semi liquid rocks to the surface . The up welling of this rocks result to formation of new crust, stretching the Lithosphere in the process.
The picture above illustrate diverging plates.
Which stage is the last stage of speciation?
The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
The populations are isolated and thus do not interbreed.
The populations become totally separated from one another.
The populations interbreed successfully.
Answer:
The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
Speciation is the evolution of one species into two different kinds, and when they become isolated, that is the final step, since they cannot interbreed any longer.
Answer: The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
Explanation:
Speciation is a process of development of new species from the parent species. This occurs when the members of the population get separated due to geographical barriers such as river, mountains and others. Or if the members of the same species diverge on the basis of morphological, physiological, reproductive and behavioral changes.
The isolated members in the end in the cases of geographical separation becomes diverge or different species as they cannot interbreed with the members of the parent species due to the adaptations according to the new environment.
