About 660 nm and orangish-red
Answer:
A
Explanation:
It is believed that the moon was formed shortly (relative time) after the earth was newly formed. This occurred in a massive planet-sized collision that ejected a huge chunk of the earth out into space. The chunk, still within earth gravitational reach, began orbiting the earth becoming the moon. Both earth and moon are slightly more than 4 billion years old.
If the temperature is too low, enzyme molecules don’t have enough kinetic energy to collide and combine with other substrate molecules. So the enzyme activity/ reaction rate will be very low. The rate will rise again once the temperature increases to its optimum temperature.
But if the temperature is too high, enzyme will be denatured, which means the shape of the active site of the enzyme is changed. It can no long combine with other substrate molecules. The rate will drop significantly. Yet, lowering the temperature won’t help because denaturation is permanent and irreversible.
All carbohydrates are made up of monosaccharides.
Explanation:
The carbohydrates are one of the crucial naturally occurring chemicals when it comes to the survival and prosperity of the living organisms. They serve lot of different roles, from providing energy, storing energy, fertilization, make up the RNA, strengthening the immune system etc.
The carbohydrates though are not all the same, and they can actually be divided into four different groups:
- monosaccharides
- disaccharides
- oligosaccharides
- polysaccharides
Each of them has different chemical composition, thus having different properties. Those different properties in turn result in different types of usages for each of them among the living organisms. The smallest units, the monosaccharides and disaccharides are actually the ones that are referred to as sugars, something that we all know very well and use it on daily basis.
