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.
The reason why a dichotomous key to identify organism is valuable, is because it helps you classify organisms,it helps you identify eco -systems, it helps you analyze an organism's traits.
Explanation:
A dichotomous key is a skill that has been brought about by scientists, to help people to identify and classify organisms.
In Dichotomous key, the main way of identifying an object is by it scientific name.This is because, though two objects might look similar to each other but they might belong to a whole different species.
So, it is is easier to identify the organism from its scientific name, as it will tell us which species it belongs to.
This key is very useful to people who are novice, and don't know much about identifying an organism.
This key also helps identifying, whether an organism belongs to a particular closely related group of organisms or is a separate organism.
It helps one analyze the traits of an organism, and based on their characteristics, it will help you identify and classify the species of the object or organism.
In the magnetotail
hope this helped!
