Answer:
Nutrition
Explanation:
Here, the answer cannot be absorption or digestion just because they are asking about intake of food, water and minerals. Digestion is a full fledged process during which food is chemically and mechanically transformed into a form through which energy can be obtained. The oprocess of digestion requires a complete digestive system that can be as simple as a vacuole in unicellular organism like eubacterium or as specialized as those of mammals like humans. Its not just about intake of food, but process of food transformation.
On the other hand, nutrition at cellular level is the process in which nutrients are obtained in any form, whether minerals, food or water. These nutrients act as our dietry supplementation and constitute the basics of our healthy diet.
Therefore, Nutrition is the correct answer.
Hope it helps! :)
Answer:
The correct answer is: d. progressive stabilisation of correct secondary structural intermediates, and unfolding of incorrect structures, until the final structure is attained.
Explanation:
- Protein folding is a sequential process and not a random one.
- It is necessary that a protein must fold in such a way that in the end it is able to attain the particular conformation which is required for its function.
- The folding of an amino acid sequence is a process that is thermodynamically favourable.
- This is because in a folded protein the hydrophobic amino acids escapes from interacting with water molecules and hence gets stabilised.
- A folded protein has lower energy and is more stable than a linear polypeptide chain.
- The folding of an amino acid linear chain into a protein takes place in the following way:
- The folding of the amino acid sequence begins during the process of translation of the mRNA (messenger Ribonucleic Acid) by Ribosome. (Co-translational folding)
- This is because initially the linear amino acid sequence forms a secondary structure (alpha helix, beta sheet) which is formed between the nearby amino acid residues.
- These structures form progressively and sequentially and each structure after formation is checked for its correct conformation before the next structure (tertiary structure) is formed.
- If an incorrect folding has occurred, the folded polypeptide chain opens up and refolds until correct orientation is attained.
- Folding, opening and refolding process continues until the correct conformation of the protein is attained.
Answer;
Opponent process theory
Explanation;
-Opponent process theory suggests that color perception is controlled by the activity of two opponent systems: a blue-yellow mechanism and a red-green mechanism.
-The opponent process theory suggests that the way humans perceive colors is controlled by three opposing systems. We need four unique colors to characterize perception of color: blue, yellow, red, and green. According to this theory, there are three opposing channels in our vision; these are blue vs yellow, red vs green and black vs white.
Answer:
Explanation:
level 3- Tiger Shark it gets 10 kg
level 2- Fish 100 kg
level 1- zooplankton 1000 kg
Manufacturer: would be the person who catches the fish and eat the fish
the last level of biomass is the tiger shark cause it gets the least amount of Kg hope this helped you :)
The earliest hominins probably lived in an extreme kind of environment.
