Answer:
the endoplasmic reticulum
Explanation:
it is the endoplasmic reticulum and the ribosomes of the specialized cells in the pancreas that make insulin
Half life is the time taken by a radioactive isotope to decay by half of its original mass. In this case the half life of carbon-14 is 5500 years.
The original mass is 30 g and the new mass is 3.75 g.
New mass = Original mass × (1/2)^n, where n is the number of half lives;
3.75 = 30 × (1/2)^n
1/8 = (1/2)^n
n = 3
Thus, the time taken will be; 3 × 5500 = 16500 years.
Answer: In the restaurant business, the use of plastic can sometimes be unpreventable, as it serves many purposes and plays a vital role in our consumption of food. One of the great advantages of plastic is that it’s designed to last for a very long time: nearly all of the plastic ever created still exists in some form today. It is in use all around us — from protecting products, to the interior of our cars, to preserving food, to the medical devices used in hospitals every day. While there are numerous positive characteristics of plastic, there are also some considerable negatives. Every day, many plastic items are only used once and then are thrown away, generating one of the fastest growing problems for the environment. We call this “single-use plastic.”
There are countless amounts of plastic items in our landfills and additionally, in our lakes, rivers and oceans. Since it takes years and years for plastic to decompose, it can release toxic chemicals into our soil and water, which can affect human health and wildlife.
With this in mind, it is important not only for individuals to reduce their plastic use, but for restaurants to lead in example by reducing the amount of plastic generated in the workplace. Many large companies like Starbucks, IKEA, and Disney have already committed to eliminating single-use plastic waste in the near future, and we expect many others will follow suit. Here are five tips to help contribute to reducing plastic waste:
