Inside our body, millions of nephrons in the kidney filter wastes in 2 steps. Each nephron has a glomerulus and a tubule. Waste filtering undergoes 2 steps:
First, fluid and waste pass through the glomerulus but, proteins, blood cells, and other large molecules are prevented from passing through. Second, the filtered fluid passes through the tubule wherein the filtered wastes are removed; minerals are sent back to the body, and the remaining output becomes urine.
The percentage of these products which are recycled include the following:
- 50% Aluminum
- 25 % steel
- 60% copper.
<h3>
What is Recycling?</h3>
This is defined as the process in which different types of waste are converted into usable materials through different processes and techniques.
Recycling is important as it helps to reduce incidences of pollution and wastage thereby improving the quality of living for humans and other organisms present on Earth. The percentage of aluminum, steel and copper products being recycled can be seen above.

The RNA codon will be GAU, pairing Cytosine-Thymine-Adenine DNA codon with Guanine-Adenine-Uracil RNA codon. This codon is the Amino Acid, Aspartic Acid. In this codon we see Uracil which is the counterpart of Thymine in the RNA.
It is practical knowledge in the sense that we know why some parts of the world are inherently risky to live in. Even though volcanic eruptionis, earthquakes and tsunamis are difficult to predict, it makes sense to have building codes and emergency plans that take this into account.
It is science’s response to the beliefs that natural catastrophes (volcanism, earthquakes and tsunamis) are divine punishments for the evil ways of some individuals.
Even if you will never use or apply this knowledge, knowing about the theory of plate tectonics gives you a current scientific perspective on what we know about the natural world.
It is a good example of how scientific theories proceed by trying to fit several observations into a coherent explanation.
Learning about the observations that needed to be made and explained for the theory to win over scientists helps caution you against people who adopt belief systems without questioning the myths told to them, or those who try to profit from ignorance of how nature actually works.
When it is well taught, it should convince you that, like any scientific theory, plate tectonics is a “work in progress”. New discoveries continue to be made, and it takes creative and logical thinking, debate and a quest for more observations in order to determine which ones prove or challenge the current theory and which ones may lead to its refinement.
Answer:
Plant cells have cell walls while animal cell do not.
