A eukaryotic cell is classified this way if it B. contains a nucleus. In biology the definition of eukaryotic is "having a true nucleus" which is how to depict a prokaryotic cell from a eukaryotic cell.
Answer:
A. The hydrogen atoms have a partial positive charge and are attracted to the oxygen atom in another molecule, which has a partial negative charge.
Explanation:
I just took the quiz. That was the correct answer.
Answer:
The correct answer is B. <em>The cells in the outer skin surface appeared flat, whereas the cells in the cross section were not flat.</em>
Explanation:
The epidermis is made up of five cell layers, which have different functions: Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
- <u><em>Stratum basale</em></u> is the <em>innermost germinative, single, basal layer of the epidermis </em>composed of basal cuboidal-shaped cells. These cells are the precursor of keratinocytes, this is why this layer is also called germinativum. In this basal layer, there are also Merkel cells as well as melanocytes.
- <em><u>Stratum spinosum</u></em> refers to the keratinocytes which produce keratin.
- <u><em>Stratum granulosum</em></u>, this is the layer where keratinization begins. Cells produce hard granules that change to keratin and lipids as they ascend.
- <u><em>Stratum lucidum</em></u> is conformed of densely compressed cells, which begins to flatten and appear indistinguishable between each other.
- <u><em>Stratum corneum</em></u> is the most external layer, composed of dead, flattened cells which are released regularly in a process known as desquamation.
That would be. All of the above.
Answer:
Besides hard and soft, conductors and isolators is another group to divide non-living things into two groups.
Explanation:
The general classification is a very hard task to do. However, if we think in absolutes we will be able to find ways to divide non-living things into two groups. Think about one thing, for example, flammable or not flammable, shinny, or opaque. We just need to find a characteristic and them see if we can group non-living things below them.
