Answer:

Henri Becquerel and the Curies worked with uranium, radium, and polonium, all of which give off radiation.

Explanation:

Henri Becquerel and Marie Skłodowska-Curie discovered the process of radioactivity. They were awarded Nobel prize for their work. Radioactivity is the process in which an unstable element emits energy in the form of radiation. This process also produce a lot of heat. Radiations are very harmful for human health however they have wide applications in modern technology.

Biologists, studying energy production in a group of frog muscle cells , observe that ATP formation in the cells can be substant
tankabanditka [31]

Answer:

<u><em>Oxygen</em></u>

Explanation:

Cellular respiration can be described as a process by which cells produce carbon dioxide and water from oxygen and glucose. Huge amounts of ATP is generated by this process. This ATP is used to carry out the normal functions of a cell.

If the oxygen supply to the frog species becomes low, then the process of cellular respiration will also slow down. Hence, by altering the amount of oxygen, the amount of ATP can be altered.

1. On a field trip to two local ponds, a group of students observed a difference between the two ponds in the diversity of worms
Gnesinka [82]

Answer:

1. Dissolved oxygen (DO) test quantifies dissolved oxygen in the water.

Impact: required for the use of oxygen (aerobic respiration) decomposition

2. Ammonia test measures the level of ammonia.

Impact: leads to algal blooms

3. Carbon dioxide test quantifies carbon dioxide .

Impact: Increased CO2 leads to decreased water pH

Decreased CO2 decreases rate of photosynthesis

Explanation:

  • Dissolved oxygen is a basic water quality test that measures the amount of dissolved oxygen in the water. This test is universally conducted in all settings involving the use of water either for drinking or farming. Oxygen is an important component of cellular respiration. It  is the terminal electron acceptor in the electron transport chain and is crucial for energy production to govern life processes.
  • The level of algal growth is an indicator of the health of an aquatic ecosystem. Ammonia is a source of nitrates, a nitrogen source required by plants and algae for optimum growth and development. Increased levels of ammonia promote unchecked algal growth, ultimately leading to the formation of algal blooms.
  • Carbon dioxide affects multiple aspects of aquatic life. Aquatic plants and algae require carbon dioxide for photosynthesis. Decreased or lower than optimum amounts of CO2 lead to decreased photosynthesis, ultimately causing plant death. Increased CO2 leads to the formation of excessive amounts of carbonic acid. Increased CO2 hinders normal gaseous exchange in aquatic animals and fish.

In the last century, the extent of global rain forests has been reduced by _____. one-half
Elodia [21]

The correct answer is - one-half.

In the past century, the deforestation of the rainforests in the world had been devastating, and it is estimated that approximately one half of the tropical rainforests have been destroyed.

The reason for the large scale destruction of the rainforests is mainly because of clearing space for agriculture and for spaces where the cattle can graze. Unfortunately, the people that live the regions where the tropical forests are, are not well educated as to how to manage the land, and a big problem is that the soil of the rainforests is only good for 2-3 seasons, because it spends and erodes very quickly. Because of that, people just continue to clear more and more of it, thus leaving destroyed forest and destroyed soil behind them, without taking in consideration the long term effects.
