How are humans impacting biodiversity in ecosystems around the world? Provide two examples to support your claim.
balandron [24]

Answer:

as humans population continues to grow, we're cutting down more trees and occupying more lands to suffice the need of citizens, therefore, decreasing the forest biodiversity. Our plastic bags, as well as wastes, are polluting the ocean and eradicating essential species that are required to sustain a balance ecosystem, therefore, decreasing the biodiversity of the ocean that are required to maintain a balance environment.

If the heart becomes damaged or weakened, how will this affect the body’s systems?
jek_recluse [69]
Think of blood as a gas/ fuel for the car ( your body). If there is no fuel, there's no movement (dead) so when the fuel tank is damaged the car won't function properly. 
 So if the heart becomes damaged, or weakened it would start making blood clots and damage the organs that need blood to function properly. The circulatory system wouldn't function properly and because other organs depend on the circulatory system it would cause a chain reaction, affecting other body systems. <span />

Outer Core of Earth

Explanation:

The outer layer of core of earth consists of iron as a major constituent. Due to internal high temperature and low pressure (as compared to the inner core) , the iron in this layer exists as liquid iron. Since the earth is rotating continuously on its axis, the liquid iron is also rotating thereby producing magnetic field. Due to magnetic field , this sphere of earth is known as magnetosphere.

When egg white is heated, it hardens and is opaque. This cooking process cannot be reversed, but hard-boiled egg white can be di
marshall27 [118]

Answer:

Generally proteins are denatured at high temperature.Therefore when  the egg is hard boiled they are denatured since eggs are protein,  the 3-dimensional  structure of protein is lost, and it is replaces with tangled meshwork of polypeptide chains .This is because the  orderly arrangements of  disulphide bonds in proteins  are disrupted , which  results in the formation of inter chains bonds among   disulphide bonds, making the protein molecules to link together.This explains the reason for the 3-D structure disruption  and formation of  a macro molecule.

However,   the  addition of reducing agent ,  breaks the covalent disulphide bonds.   While detergent breaks the interchain bonds among the disulphide bonds.  (The noncovalent bonds),These combined effects untangled the  mesh networks of polypeptides formed, and reduces the hardened nature,
