Answer:
New species develop when:
D. Diverging species no longer recognize one another as potential mates.
Explanation:
- The development of two or more new species from ancestral population is known as speciation.
- Speciation can occur when the population divides into groups and each group occupies a different habitat (geographic isolation) or when the members of the same population do not find one another as potential mate and do not interbreed (reproductive isolation mechanism).
- The three types are: Allopatric speciation.
Sympatric speciation.
Parapatric speciation.
- Allopatric speciation occurs when genetic divergence is allowed through geographic isolation.
- Sympatric speciation does not involve geographic isolation but involves reproductive isolation mechanisms.
- In Parapatric speciation, a population enters a new niche or habitat within the range of parent species and then evolution of reproductive isolation mechanism occurs.
Answer:
<em>Hi There The correct answer to this is Energy from the sun helped power the water cycle and Earth's gravity kept water in the atmosphere from leaving the planet. The oceans hold about 97 percent of the water on Earth. About 1.7 percent of Earth's water is stored in polar ice caps and glaciers. Rivers, lakes, and soil hold approximately 1.7 percent.</em>

Answer:
The answer to your question is: The first option is correct.
Explanation:
a) The primary function of photosynthesis is to use solar energy to synthesize ATP; the primary function of respiration is to break down ATP to release energy. I think this option describes best the relationship between photosynthesis and cell respiration.
b) The process of photosynthesis only occurs in autotrophs, while cellular respiration only occurs in heterotrophs. Cellular respiration also occurs in plants. So this option is incorrect.
c) Photosynthesis uses solar energy to convert inorganics to energy-rich organics; cellular respiration breaks down organics to synthesize ATP. This option is also posible but is not as complete as the first option.
d) Photosynthesis and cellular respiration occur in separate, specialized organelles, and the two processes cannot occur in the same cell at the same time. Photosynthesis occurs in chloroplasts but both photosynthesis and chloroplasts can occurs in plants.
