Answer: The correct answer is- E) structural framework.
Fibrous proteins are water insoluble, elongated filamentous like structures that that provide structural framework ( they have special types of helices in their structures) to the cells or tissues of organisms.
They contain repetitive amino acid sequences in their structure that provides strength to the structure.
They are very less sensitive to any change in pH, temperature, as well as enzymatic digestion.
They are usually involved in the formation of connective tissue.
Example of fibrous protein- Actin, myosin, elastin, keratin.
Answer:
The center section of the period table is classified into<u> transition </u> elements.
Explanation:
Transition elements can be described as elements that are present in the centre of the periodic table and are usually metals. These elements have their d sub-shells partially filled. The transition metals have high oxidation states. They have high melting points. These elements generally are known to form coloured compounds and are used for various chemistry tests. The elements from group 4 to 11 generally occur under in this category. Examples of these elements include essential elements like iron and copper.
Each organelle, in a cell, works with all of the other organelles to maintain balance, or homeostasis. The organelles have specific functions such as the mitochondria, which create energy, and the ribosome, which translates RNA into proteins. Because these cells work together, the body is able to maintain homeostasis.
Answer:
A.
Explanation:
When a power plant is made they all have these pies that come out of the buildings to extract the smoke but what most people don't know is that smoke is put out in the air and is taken to the clouds which mixes with the rain and since it is toxic it eventually leads it to be acid rain the more smog it picks up. Acid rain is very dangerous it burn down a whole forest, so yes, your answer is A.
Hope this helps :)
