Answer:
centromere
Explanation:
Chromosomal inversions, as its name suggests, are alterations that occur when a portion of the chromosome splits off but rejoins the chromosome in reverse. The genetic material remains the same, however, the disposition of information occurs in a exchanged manner.
We can classify chromosomal inversion into two types:
- Pericentric: Pericentric inversion occurs when the region undergoing inversion surrounds the centromere.
- Paracentric: Paracentric inversion occurs when the inverted region does not involve the centromere.
Answer:
Explanation:
Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly.
Answer:
D. A waxy coating on a plant
Explanation:
A cuticle can be described as a waxy covering which preserves or protects certain parts of plants like leaves, shoots etc. Lipid molecules which are saturated with waxes make up the cuticle. Cuticle majorly functions in stopping the evaporation of water from the cell's epidermal layers. All the species of plants possess this waxy coating of cuticle because it plays important role in stopping the loss of water from the cells.
Translocation theories refer to the process that explain water transportation in plants. We found three great theories: capillarity, root pressure and cohesion. Capillarity refers to the property that displays water when encounterd with small tubes, water "sticks and climbs" through the tube. The smaller the diameter the greater the climbing. Root pressure, refers to the effect salts and minerals absorbed in root, along water, exert in the content previously absorbed. That is, the "new generation of nutrients" pushes upward nutrients previously absorbed. Finally, cohesion theory is similar to capillarity. It refers to the property water molecules have to keep in close contact, due to their hydrogen bonds. Water forms a continuum through the plant. Water is losed through evapotranspiration in the leaves, so as water is losed, water from the stem starts to move. In that way water keeps the "continuum" and fills the gap that evaporated water left.
Answer:
Food additives are substances added to food to preserve flavor or enhance its taste, appearance, or other qualities. Some additives have been used for centuries; for example, preserving food by pickling, salting, as with bacon, preserving sweets or using sulfur dioxide as with wine. To maintain the nutritional quality of a food - e.g. by avoiding degradation of vitamins, essential amino acids and unsaturated fats. To provide ingredients for consumers with specific nutritional requirements e.g., sweeteners in tooth friendly confectionary or bulking agents for those seeking to reduce caloric intake.
