Answer:

In thermodynamics, a closed system can be described as a system which can exchange energy from outside but matter cannot be transferred from such a system. This means that the resources present on the Earth cannot be transferred or replaced and the waste can also not be removed. By understanding the concept of the closed system, humans should recognize the fact that many resources such as minerals present on the Earth cannot be replaced and hence, resources should be utilized effectively in a conserved manner. Also, as waste cannot be removed hence humans should stop forming such waste products which cannot be removed or recycled.

The filtrate formed by the nephrons in the kidney is NOT urine. The filtrate is first refined and concentrated by the processes
dexar [7]

The filtrate is first refined and concentrated by the processes of <u>reabsorption and secretion</u>, which form the urine that leaves the body.

<h3>Process of filtration in kidney:</h3>

The glomerulus filters your blood, and the tubule restores necessary substances to your blood while removing waste. The glomerulus is nestled within a region of the kidney called the Bowman's Capsule. This is where filtration occurs. The high pressure causes some substances to pass through the capillary walls when blood is forced through the tiny capillaries. The walls serve as a filter or sieve. This is how the function of the nephron. A glomerulus filters your blood, while a tubule restores necessary substances to your circulation while removing extra waste. Each nephron has both of these functions.

Nataliya [291]

Answer:

Error: The Methionine at the end of the chain

Explanation:

Hello! Let's solve this!

The start codon is AUG, this codon encodes Methionine. Therefore all proteins will start the amino acid sequence with Methionine.

In this case, the student placed the Methionine at the end of the chain, so that is the mistake. Methionine goes to the beginning of the chain.
