Electrons are located outside of the nucleus.

Unlike their partners; protons and neutrons, who are located inside the nucleus, electrons are only found outside the nucleus.

The correct answer is that chemicals added to the liquid can contaminate groundwater.

Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.  

The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

Respiration (both aerobic and anaerobic) begins with glycolysis in the cytoplasm of a cell;

1 glucose molecule (C₆H₁₂O₆) is converted into 2 molecules of pyruvate in a 10-step process, consuming 2 ATPs and yielding 4 ATPs;

Additionally, 2 NAD+ molecules are reduced to NADH molecules;

In aerobic respiration, each pyruvate molecule then goes through the link reaction, getting converted to acetyl co-A in the mitochondrial matrix, producing 1 CO₂ molecule and 1 reduced NADH molecule;

Acetyl co-A then enter the Krebs or tricarboxylic acid cycle (TCA) where 2 CO₂, 1 ATP, 3 NADH (by reduction of NAD+) and 1 FADH₂ molecules are produced;

The NADH and FADH₂ molecules produced are electron carriers required for the electron transport chain (ETC);

The electron transport chain consists of 4 proteins within the inner mitochondrial membrane which are involved in the production of ATP by oxidative phosphorylation;

The first protein (C1) is responsible for oxidising NADH to NAD+, releasing energy used to generate the proton motive force (PMF) by pumping the protons (H+ ions) into the intermembrane space and the electrons released are transferred to a ubiquinone molecule;

The second protein (C2) is responsible for oxidising FADH₂ to FADH, also releasing energy used to generate the proton motive force (PMF) and, similarly to C1, the electrons released are transferred to ubiquinone;

The third protein complex (C3) transfers the electrons from ubiquinone to cytochrome C;

Finally, cytochrome C transfers these electrons to the fourth complex (C4), where they combine with free protons in the matrix and O₂ to to produce H₂0;

The PMF is then harvested via an ATP synthase protein where H+ flood back into the mitochondrial matrix, and the energy released is used to generate ATP from ADP and Pi;

ATP is now ready for use for bodily processes requiring it.

Answer:

Angiosperms are the most advanced and beneficial group of plants. They can grow in various habitats as trees, herbs, shrubs, and bushes. The angiosperms originated about 250 million years ago and comprise 80% of the earth. They are a major source of food for humans and animals.

Explanation:

The 3 facts about angiosperms includes plant life, endosperm inside their seeds, and the manufacturing of end result that incorporate the seeds.

Gymnosperms. Angiosperms, additionally referred to as flowering flowers, have seeds which are enclosed inside an ovary (normally a fruit), even as gymnosperms don't have any plant life or end result, and feature unenclosed or “uncovered” seeds at the floor of scales or leaves. Gymnosperm seeds are regularly configured as cones.
