Explanation:

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.

Explanation:

The lymphocytes would quickly gather around the infected area (lymph) to immediately destroy the bacteria.

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.

Explanation:

Male produces signals of bright red, yellow epaulets and long tails.

Males produce bright red and yellow epaulets as well as chevrons on their wings. These bright epaulets attracts the female of this species and helps in the sexual activity of widowbird species.

The males of several widowbird species also grow long tail feathers about half a meter in length. The long tail is favored by sexual selection through female choice of mates. Female prefer long tails red-collared widowbird so we can conclude that male produces signals of bright red, yellow epaulets and long tails.

Explanation:

Purse seines are used in the open ocean to target dense schools of single-species pelagic (midwater) fish like tuna and mackerel. A vertical net 'curtain' is used to surround the school of fish, the bottom of which is then drawn together to enclose the fish, rather like tightening the cords of a drawstring purse.

Answer:

Explanation:

A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above.

Answer:

a year

Explanation:

The amount of time it takes for a single trip around the sun is called a period of revolution. The period for the Earth to revolve around the sun is 365.24 days or one year.

Although the picture for this question is not given, if we have the possibility to view galaxies from 100 million years ago and compare them to the photos we have today, we would see that their positions would be different.

This has to do with the fact that the universe is always expanding.

The idea of an expanding universe means that galaxies are moving farther away all the time.

However, due to the effects of gravity, some galaxies pull each other in and form groups or clusters.

Therefore, due to the formation of galaxy groups or clusters, the position of galaxies may have changed in relation to others from outside its groups in the last 100 million years, while remaining the same relative to other galaxies in its local group.

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.
