The answer is true, they are only single celled!
It is true that r-related species have a short life span and an early reproduction cycle. R-related species also known as r-strategist have a short and simple life span. Due to their simple life span, their nutrient exchange rate with the environment is rapid. Unlike K-selected species, they have the ability to reproduce at a young age. They reproduce a large number of off-springs, but many of their off-springs tend to die before attainment of their reproductive age.
The answer is reproductive isolation. Reproductive isolation ensures members of different species do not produce offspring. In this case, geographical separation is ensuring that individuals from the two different populations are not able to mate with each other. Eventually, through different selective pressures, the two populations will diverge sufficiently in genotype to become distinctly different.
Answer:
Explanation:
Photosynthesis Vs. Respiration
1) Photosynthesis gets it's energy from sunlight, and uses the sunlight to change water and CO2 into energy. Cellular respiration gets it's energy from glucose molecules and oxygen.
2) Photosynthesis uses energy, CO2, and water to make energy and releases oxygen. Cellular respiration uses glucose molecules and oxygen to make energy, and releases CO2 and water.
3) Cellular respiration takes place in the mitochondria, and photosynthesis takes place in chloroplasts.
As we get closer to the coral reef, there are going to be several things we notice. The first thing we notice will be the large number of coral that seem to have lost their color, turning bright white. In addition, if we are in Florida, we may see something called the stony coral tissue loss disease. This disease has been of great concern in recent years in Floridian waters. Looking at these two changes, we can see that both are from the impact of climate change. As the water warms, the stress on the coral reaches a high point and they start to bleach and become more susceptible to several diseases.
I hope I've helped! :)
