The milk sugar, lactose, is made up of glucose and galactose it is a dissacharide.
Thus, A disaccharide is the sugar that results from the glycosidic connection of two monosaccharides, often known as a double sugar or biose.
Disaccharides are simple sugars that are soluble in water, just like monosaccharides. Maltose, lactose, and sucrose are three typical examples.
One of the four chemical classifications of carbohydrates (the others being monosaccharides, disaccharides, oligosaccharides, and polysaccharides) is disaccharides. Disaccharides having 12 carbon atoms, such as sucrose, lactose, and maltose, have the general formula C12H22O11.
Thus, The milk sugar, lactose, is made up of glucose and galactose it is a dissacharide.

The nutrient that can be found in all organic compounds is the carbon. The reason why carbon is found in all organic compounds is described below.
Organic compounds are those chemical compounds found in living organisms which are made up of carbon-hydrogen bonds.
Carbon is the main element in organic compound since it forms its bonds. Typical examples of these organic compounds are:
Therefore, The nutrient that can be found in all organic compounds is the carbon.

Secondary succession can happen after primary succession or independently of primary succession.
a. True
b. False
Which of the following about secondary succession is not true?
a. It occurs in ecosystems without soil.
b. It occurs in ecosystems that are already established.
c. It reduces the number of species in an ecosystem.
d. It is ...
1. Answer;
-Fungus
Explanation;
-A pioneer species is one which is the first to colonize an area, which can be seen with fungus in the way that spores are quickly spread across large areas.
-Pioneer species are usually lichens and mosses, which can grow on bare rocks. As they grow, the lichens and mosses help break up the rocks to form soil. When these organisms die, they provide nutrients that enrich the developing soil. Over time, seeds of plants land in the new soil and begin to grow.
2. Answer;
The statement above is true
Explanation;
-Secondary succession can happen after primary succession or independently of primary succession.
-Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation by forest fire, tsunami, flood, or an abandoned field.
-Secondary succession may occur independently, but the stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil.
3. Answer;
A. It occurs in ecosystems without soil.
Explanation;
-Secondary succession refers to the process that happens after a disruptive event, reducing the population of species in an ecosystem. As opposed to primary succession that occurs in an ecosystem lacking soil, secondary succession happens on preexisting soil.
-Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.
Grass is an example of a pioneer species, so option d is correct. The second statement is True. Secondary succession can happen after primary succession or independently of primary succession. Secondary succession reduces the number of species in an ecosystem thus the answer is (C).
Hardy species called pioneer species are the first to establish themselves in once-biodiverse steady-state ecosystems. Lichens, fungi, bacteria, fireweed, grasses, alder, and willow are examples of pioneer species.
In primary succession, living organisms first occupy newly exposed or newly created rock. In secondary succession, a previously inhabited area is disturbed, disrupted, and then recolonized as a result of the disturbance.
In third question, among all the given options only option (c), "it reduces the number of species in an ecosystem" is not true.
Before secondary succession starts, a variety of species will already be present in the ecosystem and new complex plants and animals move in as the ecosystem develops, bringing with them new species. so it will increase the number of species in an ecosystem.
Therefore, in question 1st, option d is right, in question 2nd, the given statement is true, and in 3rd, option c is right.

The complete part of 3rd question is:
Which of the following about secondary succession is not true?
A) It occurs in ecosystems without soil.
B) It occurs in ecosystems that are already established.
C) It reduces the number of species in an ecosystem.
D) It is initiated by a disruptive event.
Answer:
The correct answer is - the amount of the light received by pots.
Explanation:
An Independent variable is a type of variable which is a change or manipulated in aspecific research or study to find the response of the dependent variable.
In this study, to find the effect of the light on the plant Mrs. Hendren uses the time period of light received by the pots of the plant in order to see the effect on the plant. So the variable that is manipulated is the amount of the light received by the pots.
B. plant specimens
C. all chemicals
D. bacterial cultures
Bacterial cultures is the correct answer
