1) They are both Eukaryotic cells.
2) They lack cell wall.
Eukaryotic cell are cells that have a nucleus enclosed within membranes. Also, there are numerous membrane bound organelles which includes Golgi apparatus, mitochondria, Endoplasmic reticulum and Chloroplast.
Cell wall is rigid in nature and semi-permeable protective layer found in cells. They are positioned next to the cell membrane in most fungi, bacterial and plant cells but absent in Animal cells. Furthermore, they perform many important functions in the cell which includes protection, structure and support.
However, both human being and Ameoba have Eukaryotic cells and lack cell wall.
Answer:
<h2>letter A</h2>
Explanation:Whittaker placed bacteria in their own kingdom, Monera, because of fundamental organizational differences between prokaryotic bacterial cells, which lack membrane-enclosed nuclei and organelles , and the eukaryotic cells of other organisms that possess internal membranes. Plantae, Fungi, and Animalia consist of complex, multicellular eukaryotic organisms that differ from each other in details of cell structure and in how they secure and process energy. Protista is a collection of single-celled eukaryotic organisms and simple multicellular forms, some animal-like, some plantlike.
<h2>letter b</h2>
Molecular evidence, particularly from ribosomal ribonucleic acid (RNA), suggests that the five-kingdom scheme is also too simple. Some biologists believe that Protista should be partitioned into three or more kingdoms. Similarly, kingdom Monera contains two very biochemically distinct groups of prokaryotes: archaebacteria, and eubacteria. A proposed system acknowledges this ancient evolutionary split by creating a higher level of classification, domain, above kingdom. This system distinguishes three domains: Archaea, Eubacteria, and Eukarya (containing protists, plants, fungi, and animals).

Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.
Answer: b. Webbed-toed mice survived better and reproduced more than mice without webbed toes.
Explanation:
Natural selection is a phenomenon that suggests that organisms that have a better structural and morphological advantage over the others have better chances of survival over the others.
The webbed toed mice have a survival advantage over the without the webbed toes because this can help the webbed toed mice to swim. The webbed toed trait will be beneficial and passed on to the next generation of the mice and the webbed toed mice will reproduce more than the mice without webbed toes.
