n the 1950’s, Anfinsen carried out denaturation and renaturation experiments of the protein RNAse (ribonuclease) in vitro. After

beks73 [17]

Answer and Explanation:

The regular synthetic denaturant of proteins is urea. The high grouping of urea causes unfolding of protein and accordingly brings about loss of capacity of protein. The urea communicates with the protein and counteracts collapsing of protein.

During oxidation, the disufide bonds that are required for legitimate working and adjustment of protein are shaped, while in nearness of urea, the disulfide bonds are not situated effectively. The protein oxidation brings about covalent adjustment of protein that outcomes in change of physical and substance properties of protein.

The difference in physical and chemical properties of protein after oxidation and in nearness of urea can't be altered even after expulsion of urea. Along these lines, protein doesn't crease appropriately.

<em>Hi there, I come in behalf of jcherry99,</em>

So, first question -

This shouldn't be that much of an issue, since we have the text to help us out, but I'll try breaking it up into more simpler words:

The placenta is incide the uterus, where the baby starts forming. As you might already know, babies do not eat while they're inside woman's bellies:

So how do they feed?

They feed throught the umbilical cord.

So why is the placenta there? Why would the baby want anything apart from food?

The placenta, instead of trading food with the baby, regulates temperature, supplies it with nutrients, exchanges gas with the mother (which the mother later exchanges with the environment) and gets rid of waste.

And, food is not everything for a baby that is in the urge of developing complex muscles, bones, etc.

Second "question" -

I do not actually know what I'm supposed to do, since there is no question. But I can tell you this - the information contained in part B is correct:

The amnioic sac provides babies with a liquid which allows him to move freely in the uterus, which is very helpful. But, note that he doesn't start moving randomly, he is always in a fetus or similar-to-fetus position.

Hope it helped,

My name is Ann [436]

Indigenous Information System (IKS) is the body of knowledge that communities have accumulated over many generations as a result of their interactions with the environment.

<h3>Indigenous Knowledge System (IKS): What is it?</h3>

The technological, economic, philosophical, educational, and governing systems are all included in the indigenous knowledge system.

Prior to the development of the contemporary scientific knowledge system, indigenous societies established their own knowledge, which is included in indigenous knowledge systems (IKS).

Acupuncture from China is an illustration of IKS. Through the preservation and wise use of biodiversity, it may significantly advance sustainable development.

There is a definite need to preserve these systems, acknowledge their worth, and stop their destruction in order to strengthen indigenous knowledge practices and cultures.
