A carbohydrate composed of two covalently bonded simple sugars is called a <u>disaccharide</u>.
Carbohydrates or sugars are one of the four main categories of the macromolecules that make up living things (the other three being nucleic acids, proteins and lipids). It can either be a simple sugar (sugar monomer or monosaccharide) or a polymer of simple sugars.
Carbohydrates are composed entirely of carbon, oxygen and hydrogen atoms. Simple sugars or monosaccharides contain six carbon atoms, twelve hydrogen atoms and six oxygen atoms. When two monosaccharides bond covalently, they form a disaccharide.
Some examples of disaccharides include:
- Sucrose or table sugar - It is made up of one glucose molecule and one fructose molecule
- Lactose or milk sugar - It is made up of one glucose and one galactose molecule
- Maltose or malt sugar - It is made up of two glucose molecules.

Recessive traits would never reappear if zygotes were given opposite alleles.
<h3>What do you mean by Zygote?</h3>
Zygote may be defined as the outcome of the fusion of male and female gametes after successful fertilization.
Recessive traits are only expressed when both the copies of recessive genes are inherited from the parents.
Therefore, recessive traits would never reappear if zygotes were given opposite alleles.

Answer: These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell? divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid. Meiosis produces our sex cells or gametes? (eggs in females and sperm in males).
Explanation:
Difference # Open Store System:
1. There is no specific storage area. Stores are maintained in the form of Suitable/convenient locations.
2. Every individual has access to anystorage facility.
3. After the receipt of the material it is delivered to respective department to expedite the production activity.
4. Chances of Pilferage high.5. Less emphasis on accounting control of the material.
Difference # Closed Store System:
1. All materials are stored in a closed/controlled area.2. No other person than the stores personnel is permitted in the area.
Materials can leave or enter the storage area only by authorised documents.
4. Maximum Physical Security.
5. Tight accounting control of inventory material.
