Which of the following practices that are needed to run a nuclear power plant has a negative impact on both air and water?a.
cooling of the power plant
b.
mining of uranium
c.
storage of radioactive waste
d.
monitoring the reactor

Answers

Answer 1
Answer:

The correct answer is option B

The mining of uranium is harmful for both air and water. Uranium is a radioactive compound that is extracted by mining.

Uranium ore emits the gas named radon. The health effects of exposure to radon have particular problems. Significant rate of lungs cancer was observed during the 1940s and 1950s.

Water is used in the heap leaching of the uranium mining. The water can get mixed into the normal supply of water and harm the health of people.

Answer 2
Answer:

Mining of the radioactive element Uranium has the following negative effects on both air and water such as contamination.

What is Uranium?

This is a a silvery-white metallic chemical element in the periodic table, with atomic number 92 and is commonly used to run nuclear power plant.

it exists in the air and when contaminates water could lead to kidneyailments in affected individuals which is why option B was chosen as the most appropriate choice.

Which is a good example of a shield volcano?

Answers

Mauna Loa is a example of a shield volcano. Hope this helps you.

Answer:

Kilauea and Mauna Loa are both shield volcanos located in Hawaii . All the volcanoes on the Hawaii islands are shield volcanoes. Examples of shield volcanoes include Kilauea, Mauna Kea, and Mauna Loa in Hawaii, Isabela Island in the Galapagos, and Olympus Mons on Mars.

Explanation:

A shield volcano is a type of volcano that has been formed by lava flow. Shield volcanoes are large and wide with a low profile. The crater at the volcano is not far above sea level in comparison to a composite volcano. Most shield volcanoes are super-volcanoes.  A shield volcano is a volcano with shallow-sloping sides. Shield volcanoes are formed from fluid lava that can travel long distances across slight inclines, resulting in their relatively flat, broad profile. In contrast, steeply sloped stratovolcanoes better match the popular stereotype of a volcano.  

How do the outer planets compare to the inner ones? A.

The ________ photosynthetic reactions convert light energy into chemical energy, which is stored in molecules like ATP. In the _________ photosynthetic reactions, this energy is used to convert CO2 into carbon sugars. A) light dependent; chloroplast
B) chloroplast; light independent
C) light dependent; light independent
D) light independent; light dependent

Answers

Answer:

C

Explanation:

light-dependent reactions require sunlight. In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of the electron carrier molecule NADPH (nicotinamide adenine dinucleotide phosphate) and the energy currency molecule ATP (adenosine triphosphate). The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast.

While In the light-independent reactions, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.

So the answer is definitely C

Answer:

Your answer would be C; Light dependent, light Independent

Multiple choiceAn ionic bond:

Three examples of bacteria billions of years ago

Answers

three examples of bacteria billions of years ago are the coccus, bacillus, and spirochete

Final answer:

Bacteria billions of years ago played a critical role in shaping the Earth's atmosphere and the development of life. Cyanobacteria, archaea, and stromatolites are examples of bacteria from that time.

Explanation:

Billions of years ago, bacteria played a crucial role in shaping the Earth's atmosphere and the development of life. Some examples of bacteria that existed back then include:

  1. Cyanobacteria: These ancient bacteria were the first organisms capable of photosynthesis, releasing oxygen as a byproduct and contributing to the oxygenation of our planet's atmosphere.
  2. Archea: Certain types of archaea bacteria, such as methanogens, were present and played a role in the early carbon cycle, producing methane gas.
  3. Stromatolites: These are fossilized bacterial mats found in ancient rocks, providing evidence of early bacterial life and their important role in Earth's history.
