The sickle cells have membranes stretched by their usual shape that becomes porous and leak nutrients that the parasite needs to survive and the faulty cells eventually get eliminated quite fast by the organisms destroying the parasite among the way
Answer:
1. FtsZ tubulin homolog
2. actin and tubulin
3. actin and tubulin
4. b. animals and bacteria
Explanation:
1. In bacteria, the binary fission process takes place when the cytoskeletal structure of the bacteria are assembled to form the contractile ring in the centre of the cell. The contractile ring in bacteria is composed of the Z-protein which is a tubulin homolog.
2. Plants: the plants divide by the cell plate formation and not the contractile ring formation. This is mediated by the actin, tubulin and vesicle produced from the dictyosomes.
3. Animals: a contractile ring attached to the plasma membrane is formed which is composed of the F-actin and tubulin.
4. Since the bacteria and animal cytokinesis involves the formation of the contractile ring and thus the same mechanism of cytokinesis.
Answer:
As quantitative data collection methods are often based on mathematical calculations, the data obtained that way is usually seen as more objective and reliable than qualitative. Some of the most common quantitative data collection techniques include surveys and questionnaires (with closed-ended questions).
Explanation:
Fossils provide<span> solid </span>evidence<span> that organisms from the past are not the same as those found today; they show a progression of </span>evolution<span>. Scientists calculate the age of </span>fossils<span> and categorize them to determine when the organisms lived relative to each other.</span>
