Explanation:
<em>The chloroplast is an organelle through which photosynthesis takes place. While the light reaction takes place in the thylakoid membrane of the chloroplast, the light-independent reaction or the Calvin cycle takes place in the stroma of the chloroplast. </em>
<span>Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.</span>
Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.
<span>The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.</span>
D) competition for resources is greater
The more in the population, the more resources needed. If they run out of resources, the population decreases. They are competing to stay alive. I hope this helps!
The sugar and phosphate portion of the nucleotides are found "<em><u>as segments of the rails</u></em>" on the DNA twisted ladder.
