<span>The appropriate answer is A. the hemisphere is is tilted toward the sun and the sun reaches its highest point in the sky. This usually occurs on June 20 or 21. At this time the northern hemisphere experiences its longest day. Summer in the nothern hemisphere means that the earth is tilted towards the sun and receives sun rays that are more direct. </span>
* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.
* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.
Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.
A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules
The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.
Because people had as pets when they got to big they let them into the wild and they came a different place
Answer:
1) Increased probability of hazardous chemical contamination.
2) Air, water, and soil pollution.
3) Mortality in both terrestrial and aquatic organisms.
4) Development of diseases in humans.
Explanation:
The improper disposal of electronic waste can have detrimental consequences for the environment and, as a result, to all living beings including humans.
If electronic waste is thrown away in an open area, it warms up and releases hazardous chemicals that are detrimental for the health of living beings. This occurs because <u>electronic objects contain toxic chemicals such as lead, mercury, cadmium, amongst others</u>.
These chemicals will eventually enter both soil and water, harming thousands to millions of terrestrial and aquatic organisms. Moreover, these chemicals will enter the food chain and, as humans consume these affected organisms, we are also affected in numerous ways. For example, ingesting these chemicals could cause reproductive issues, damage to both the nervous and digestive systems, the development of cancer, etc.
Cap and Trade is the equivelent to carbon footprint
