Answer:
Proteins range in molecular weight from 1000 to more than 1 million daltons (Da), but the folded size of a globular protein is not necessary correlated to its molecular weight. Proteins composed of about 250 amino acids or less often have a simple, compact globular shape. Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces. Individual domains often possess unique functional behaviors and often perform unique functions within the larger protein in which they are found.

How does an iron nail change after being exposed to the oxygen in the air over a long time? Question 24 options: It burns It decays It molts It rusts
Answer:
It rusts
Explanation:
Iron is a chemical element that has the ability to RUST when exposed to air and water. Rusting is actually a prolonged chemical process or change that results when iron reactively combines with water and oxygen in the atmosphere to from hydrated (III) oxide in a process called OXIDATION. This compound is behind the color change of the metal.
According to this question, a nail made of iron will change after being exposed to the oxygen in the air over a long time by RUSTING via the oxidative reaction of the iron constituent of that nail with oxygen.
Which two characteristics are shared by all thunderstorms, tornados, and huricanes?
O clouds and wind
O eyes and clouds
O warm, dry air and wind
O large waves and warm, dry air
The two characteristics that are shared by all thunderstorms, tornadoes, and hurricanes are: clouds and wind. The correct option is A.
What are the characteristics of thunderstorms, tornados, and hurricanes?Thunderstorms, tornadoes, and hurricanes are all types of severe weather conditions. They are called severe weather conditions because they can cause a lot of damage to property and people's lives. They are all characterized by strong winds and clouds.
Thunderstorms are storms that have thunder and lightning. They are caused by warm air that rises and cools, creating thunderstorm clouds. They are usually accompanied by heavy rain, gusty winds, and lightning.
Tornadoes, on the other hand, are funnel-shaped clouds that touch the ground. They are usually created by thunderstorms. They are characterized by strong, rotating winds that can cause a lot of damage to structures and vegetation.
Hurricanes are large, tropical cyclones that have low-pressure centers. They are usually formed over warm ocean waters and are accompanied by strong winds, heavy rain, and flooding. They can cause a lot of damage to coastal regions and people's lives.
Therefore, the correct option is A.

Explanation:
Which is one factor that contributes to the formation of polar, temperate, and tropical zones?
the angle of the Sun's rays
the direction of seasonal winds
the presence of prevailing winds
the movement of wind near a mountain
The one factor that contributes to the formation of polar, temperate, and tropical zones is the angle of the Sun's rays. Thus, option "A" is correct.
What is the climatic condition of tropical zones?The climate on Earth can be divided into three major zones, tropical, temperate, and polar.
The tropical ones are at the Equator and near to it, the temperate ones are at the mid-latitudes, and the polar ones are at the higher latitudes.
This is a result of numerous factors, such as the shape of our planet, as the sunlight falls at different angles at different parts of it, so some parts get much more heat, while some much less.
Thus, option "A" is correct.

One factor that contributes to the formation of polar, temperate, and tropical zones is the angle of the Sun's rays. The angle of the Sun's rays determines the amount of solar energy that reaches a particular region.
What is the cause of formation of polar?This is due to the Sun's rays, which are more oblique in the northern regions and more direct in the tropics. The length of the day in a specific location is also influenced by the Sun's rays' angle. The duration of the day is longer in the tropics than in the polar regions, and this directly affects the local temperature.
The Sun's rays are directed more directly and at higher angles, which results in higher temperatures. Predominant winds also aid in the development of the arctic, temperate, and tropical zones. Predominant winds move warm air from the equator to the poles and vice versa, which has an impact on a region's temperature.
The temperature of an area is also influenced by the direction of the predominant winds. For instance, temperatures in the area will be lower if the predominant winds are from the east than if they are from the west. Predominant winds have an impact on the amount of moisture in the air, which can change a region's climate.
Polar, temperate, and tropical zones can also occur as a result of wind movement close to mountains. This is so that the mountain and the surroundings won't be separated by the wind.

Advantages of using ethanol as fuel
A. It is a carbon-neutral activity
C. It does not produce toxic gases when burnt
D. It can be mixed with conventional petrol to make gasohol
Disadvantages
B. It takes a lot of plant materials to produce the ethanol
Explanation:
It has been proven that blending ethanol with conventional petrol produces gasohol and this helps to reduce the harmful emissions of CO, hydrocarbons, etc. This then means that vehicles that run on ethanol produces fewer harmful emissions than those that run on gasoline. For ethanol, it produces a no net carbon dioxide emissions.
Ethanol is considered to be atmospheric carbon neutral when the combustion of ethanol is made from biomass (such as sugarcane and corn). Ethanol is made plant materials like grains and crops that possess high starch. Also, it can be made from sugar content such as sugar cane, sorghum, corn, barley and sugar beets.

Write characterize progression of infectious disease.
Answer:
* Infectious disease management depends on precise portrayal of disease progression so transmission can be forestalled. Gradually progressing infectious diseases can be hard to characterize because of a latency period between the time an individual is infected and when they show clinical signs of disease.
* Defining directions through sickness states from infection to clinical illness can assist researchers with creating control programs dependent on focusing on individual infection state, possibly decreasing both progression and creating misfortunes because of the illness.
Explanation:
Gradually progressing infectious diseases are hard to characterize in light of the fact that they are frequently connected with an inactivity period between the time an individual is infected and when they give clinical indications or side effects of illness.
To successfully control infectious diseases, it is paramount to see how the disease progresses.
