The endosymbiotic theory says that precursor eukaryotic cells acquired cilia by endosymbiosis with a(n) _____ ancestor and other
7nadin3 [17]

Answer:

The correct answer is spirochete and cyanobacteria

Explanation:

The endosymbiotic theory states that the eukaryotic cells are evolved from prokaryotic cells when a larger prokaryotic cell engulfed the smaller prokaryotic cell. The presence of chloroplast and mitochondria supports this theory.

After genetic analysis of chloroplast DNA, it was seen that it closely resembles the cyanobacterial DNA which shows that ancestor host cell gained photosynthetic ability from endosymbiosis with a cyanobacterial ancestor.  

It was also seen that ancestral host cells engulfed spiral bacteria called spirochetes which helped them to produce cilia for example tail on sperms is the result of endosymbiosis of spirochete. So the right answer is spirochete and cyanobacteria.

Write a short story describing an application of biological classification
timurjin [86]
All living creatures are classified into systems and sub-systems based on their similar characteristics. They are divided from bigger groups into smaller groups based on the detail of their similarities i.e. how they look, move, reproduce and how they relate to each other. A practical way of understanding the classification of living organisms is that organisms are linked to other similar organisms via family trees. The classification of all living creatures includes at least four levels: order, families, genus and species.

Which of the following is the correct order of events in mitosis?
MA_775_DIABLO [31]

Answer:

The last option is the correct order of events in mitosis.

Explanation:

The metaphase stage initiated with the arrangement of sister chromatids on the metaphase plate. Post arrangement, the spindle fibers come and combine with the chromatids kinetochore. The cohesion proteins assist in the robust attachment of the spindle fibers and the kinetochore. After the attachment is done, the pulling of sister chromatids takes place towards the pole. The dissociation of cohesion proteins takes place, and the nucleus begins to form again and thus, a novel cell gets formed.
