Answer:
plant cells have a cell wall and animal cells dont
Answer:
There are many types of evidence which support the theory of evolution such as comparative anatomy, fossil records, phylogenetic relationship, embryology et cetera
Comparative anatomy includes homologous organs and analogous organs. They support divergent and convergent evolution respectively.
For example, the homologous structure of limb of humans, birds, bat, horse, whale et cetera show that they are made up of the same set of bones which are humerus, radius, ulna, carpals, metacarpals, and phalanges.
It shows divergent evolution and supports that these organisms have evolved from a common ancestor.
Embryological evidence: When early stages of embryological development of different organisms are compared, it is found that these stages are similar at different levels of development.
For example:
- The appearance of pharyngeal-arch (gill-like structures) in vertebrates during embryo development.
- Salamanders and terrestrial frogs pass through larval stages within an egg. They possess the features similar to aquatic larvae, however, when they hatched out the eggs being ready for life on land.
Answer: Homologous Structures
Explanation:
Answer:
It will be observed that in the cell that undergoes the division there is a constriction of the membrane and part of the cytosol, with its chromatic poles at the ends and even possibly double genetic load in the center.
Explanation:
In general, these cells are seen with eosin and hematoxycillin, with which, their internal media will be more basophilic, with more violet staining since they have a high protein load in their interior due to the great genetic load.
During cell division, the genetic load increases because the amount of material is doubled to give a daughter cell.
