Answer:

Human activity can affect the amount of carbon in the atmosphere. When fossil fuels like oil, coal, and natural gas are burned, carbon dioxide is released into the atmosphere as waste. The clearcutting of forests for lumber and fuel also increases levels of carbon dioxide in the atmosphere because the trees can no longer remove carbon dioxide from the atmosphere for photosynthesis. If trees are burned in order to be cleared, the burning processes release even more carbon dioxide into the air.

Which of these are found in both eukaryotes and prokaryotes (choose all that apply)
kaheart [24]

Answer:

The correct answers are option b. "replication bubbles" and d. "replication forks".

Explanation:

The nucleic acids replication systems share some similarities between eukaryotes and prokaryotes. For instance, both organism have replication bubbles. However, prokaryotes have a single replication bubble because its replication process starts from a single origin, while eukaryotes have several replication bubbles. Also, the replication forks are well conserved from prokaryotes to eukaryotes with only some differences among the enzymes present within the fork.

If the supply of carbon dioxide stops in plant, what will happen to the process of
V125BC [204]

Answer:

All plants and animals on earth engage in a process called respiration. Respiration combines oxygen and the food created during photosynthesis to produce usable energy. One of the byproducts of respiration is CO2, this is the opposite of photosynthesis. It is not unusual for plants to stop taking in carbon dioxide to uptake small amounts of oxygen at night.

In the event that plants cease to take up CO2 all together, they will cease to convert sunlight into carbohydrates, and die. The death of autotrophs would lead to a chain reaction of the death of all higher order organisms. Mankind could survive on food stuffs on hand, but only for a very short time. It has been said that any western society, its members are just 3 meals away from revolution.

Social order would be completely lost during the initial food riots. Once the processed and packaged food supply is exhausted, it would be the law of the dying jungle. The strong and well armed would take from the weak and ill prepared. Livestock and game would be slaughtered as the next to the last food source disappeared. The shear volume of death would foul the water spreading pestilence and disease. In one or two years bands of humans would prey on other humans as they degenerate into cannibalism. There could be a few humans in protected bunkers and hideaways, but they too would eventually succumb to starvation or despair as the world died.

The fact that plants stopped converting CO2 into O2 would be of little consequence. Man would die of hunger 1000 years before oxygen was ever an issue.
