How has the extraction of tarsands changed over time?

Biology
1 answer:
eduard3 years ago
6 0
Tar sands (also called oil sands) are a mixture of sand, clay, water, and bitumen.[1] Bitumen is a thick, sticky, black oil that can form naturally in a variety of ways, usually when lighter oil is degraded by bacteria.[2] Bitumen has long been used in waterproofing materials for buildings, and is most familiar today as the binding agent in road asphalt. However, most of the bitumen produced from tar sands is refined and mixed with lighter oils to produce synthetic crude oil that can be further refined and used in much the same way as typical crude oil.[3]

Because bitumen is very thick and does not flow easily,

The unique method of locomotion in octopus has been utilized by successive generations of octopus through the process of evolution. Evolution is defined as the change in the characteristics of a species over several generations. This type of behaviour is attain by octopus in order to save itself from its predators such as shark so we can say that this unique method of movement is used by octopus to save itself from the predators leads to evolution in the octopus.

Describe how the structural makeup of a muscle contributes to the muscle's ability to do its job.
Nady [450]

The basic structure of a muscle fiber is comprised of actin and myosin protein chains that straddle each other in a fusiform arrangement. The actin and myosin arrays interlock and move past each other to cause contraction of the muscle. They then move back to their initial positions in relaxation. This gives muscles their elasticity and distensibility.  The muscle fibers are bundled, in their 10s to 100s up into myofibrils around an endomysium. Many myofibrils are also bound up in a perimysium to form a muscle fiber.

In an experiment, you create two groups of liposomes in a solution containing 0.1 M NaCl—one made from red blood cell membranes
mars1129 [50]

Answer:

As liposomes with red blood cell membranes burst more rapidly than those made from egg membranes, we consider these liposomes as more hypertonic respect to water, than those derived from frog egg cells.

Explanation:

Osmosis is a process where water can cross a semipermeable membrane in a gradient way.  Water tends to move from a high concentration of solvent to a low concentration.  Then, water goes in through the liposome to dilute its solute content, as it's not easy for molecules inside to go out of the usually impermeable membrane bilayers.

Explain the movement of carbon through photosynthesis and cellular respiration
Gnoma [55]
<span>Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
