Answer:
Explanation:
The centromere is also known as the microtubule organizing center. The spindle fibers provide a framework and means of attachment that keep chromosomes organized, aligned and assorted during the entire process of mitosis, lessening the occurrence of aneuploidy, or daughter cells with incomplete sets of chromosomes.
Answer:
C. The fundamental unit of all matter, both living and nonliving
Answer:
The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.
Explanation:
The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.
The process of <u>cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions</u> where, from a glucose molecule, energy is obtained in the form of ATP molecules.
Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:
<em>C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂</em>
This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.
For the other options it is important to mention that:
- <em><u>C₆H₁₂O₆</u></em><em> is the substrate from which cellular respiration takes place.
</em>
- <em><u>ATP </u></em><em>is the final product of cellular respiration, translated into energy to be used by the cell.</em>
Competitive advantages of apple were;
Apple preferred Horizontal and vertical integration around its products instead of licensing it or making it open market or sharing the technology.
Easy to use- they focused on ease of operation and simple user interface.
Facility of plug and play so that non-technical users do not face any issues.
Uniqueness and innovation in enhancing consumer's digital life for example- Digital Hub- an advantage for consumers who were becoming entrenched in a digital lifestyle, using digital cameras, portable music players and digital camcorders and mobile phones.
Investment in R&D brought the key competitive advantage to apple.
Fatty acids in the cells are amphiphile, it means they have a polar side (phosphate group) and apolar side (carbon tails).
<u>The polar property</u> helps the cell to adapt with the aqueous medium (in both sides of the membrane).
<u>The apolar property</u> helps the membrane to keep its integrity. Since they "hate water" the apolar side of phospholipid will stay on the inner side of the membrane and be joined together to keep the integrity of the membrane. It contributes also to the viscosity of the membrane.
If this apolar property doesn't exist, The membrane will be too water soluble and dissolves in it, and the cell could not keep its integrity
