Answer:

You would expect to find glutamic acid on the fringes of the three-dimensional protein structure while valine would be found mostly inside the protein structure.

This is because hydrophilic molecules are ‘water-loving’ because they carry a charge and can, therefore, interact ‘positively’ with water by forming hydrogen bonds with the polar water molecules. Hydrophobic molecules on the other hand are water-hating. They carry no charge hence have no way of ‘positively’ interacting with the polar water molecules.

Remember the structure of the cell membrane too? The negatively-charged phosphate ends of the phospholipid bi-layer sandwich the non-polar fatty acid chains because they don't ‘like’ interacting with water. This applies to the same principle.

sesenic [268]

Answer:

A. 50, 88, 145, 227

Explanation:

The correct option would be option A.

<u>When something grows exponentially, it means the growth increased at a high rate. More specifically, each rate of increase results in more or less doubling of the preceding rate. For example, if the current value of growth rate is 2 for a substance that is growing exponentially, the next growth rates will be 4, 8, 16, etc.</u>

<em>In this particular illustration, the only option that best fit into an exponential system is option A in which the growth rate more or less doubles each time from 50 to 88, from 88 to 145, and then from 145 to 227.</em>

If the population of Shanghai increases to 30 billion people, how much land would its people need if the population density is 3
nadezda [96]

784109 People per sq. mi land would its people need if the population density is 3,826 people/km2.

<h3>What is population density?</h3>

The density of individuals within a species in a given geographic location is referred to as population density. Data on population density can be used to calculate demographics and examine interactions with ecosystems, human health, and infrastructure.

The population density equation below can be used to calculate the population density of a piece of land:

        Population Density = Population/ Area

The residential density is important in determining the people's thinking and culture. Engineers find it vital to forecast population growth in order to develop infrastructure that can support a large population. It is practically impossible to develop a perfect 3D model of any structure that allows the largest number of people to live without this understanding.

Explanation:

Restriction enzymes has the ability to recognize specific DNA sequences and cut them in a specific manner in order to produced by the bacteria as a defense mechanism against foreign DNA containing substance such as viruses etc. This restriction enzyme is also called restriction endonucleases. This is a cloning tool that bacteria produced naturally in order to defend itself from the infection of virus.
