Lactose, or milk sugar, is composed of one glucose unit and one galactose unit. It can be classified as a disaccharide.
<h3>What is
disaccharide?</h3>
Any material made up of two simple sugar molecules (monosaccharides), coupled to one another, is referred to as a disaccharide, often known as double sugar.
A disaccharide (also known as a double sugar) is the sugar that results from the glycosidic connection of two monosaccharides (simple sugars). Disaccharides are water soluble, just as monosaccharides. The sugars sucrose, lactose, and maltose are three typical examples.
Disaccharides. Two monosaccharide units are joined by glycosidic linkages in either the or orientation to form disaccharides. Sucrose, lactose, and maltose are the three most significant ones.

T pollen grain fertilizes an egg cell while a second fuses with two polar nuclei to produce a triploid body that gives rise to the endosperm.
Cladograms are detailed oriented and impossible to show evolutionary relationships and this among the following statements best describes a challenge in classifying organisms in this way. The correct option among all the options that are given in the question is the third option or option "C".
Answer:
The best answers to the question: Which of the statements are true? Would be the following:
1. Fats that contain more saturated fatty acid residues than unsaturated fatty acid residues are more likely to be solid at room temperature.
3. Unsaturated fats are more likely than saturated fats to be liquid at room temperature.
5. Triacylglycerols (tryglicerides) are composed of fatty acid residues and glycerol.
Explanation:
The options chosen from the five options are all characteristics of triglycerides. These molecules, which are pretty complex, have all of the options above except for 2 and 4 because these molecules, especially unsaturated fats do not have a high melting point, that is why they remain liquid at room temperature. So that option is wrong. Also, although tryglicerides do have carboxyl groups, chemically speaking they are better categorized as esters.
Answer:
The mass of a star determines its life cycle, that is, more the mass, shorter will be its life cycle. The mass of the star is determined by the concentration of matter, which is found within its nebula. In the nebula, with time, the hydrogen gas comes in close proximity with each other due to gravity and starts to spin.
With the brisk spinning, the gas heats up and turns into a protostar. The temperature now reaches 15,000,000 degrees and within the core of the cloud, the phenomenon of nuclear fusion takes place. The cloud now contracts a little, starts to glow brightly, and turns stable. The cloud now becomes a prime sequence star, and will stay in this phase for millions of years, the Sun of our galaxy is in this stage at the moment.
