<h3><u>
Answer;</u></h3>
C. Different species can share the same common name.
<h3><u>Explanation;</u></h3>
- <em><u>Different organisms can share the same common name</u></em>, and thus the reason why scientists avoid using common naming while naming organisms.
- Additionally, s<em><u>cientists avoid using common names because they are not specific to a specific species.</u></em> For instance, Robin is a common word that may be used to describe the many species of robin that are found in different regions of the earth, for example, Robin in England which has yellow breast, and robin in United states and have red breasts.
- Therefore, <em><u>for the purpose of avoiding ambiguity and confusion in naming organisms scientists use scientific names while identifying various species.</u></em>
Well, to answer your first question, Because there are places on Earth that are both biologically rich — and deeply threatened. For our own sake, we must work to protect them. and for your 2nd question, 3 characteristics of magnetic reversal are: field, bar magnet, and molten material. Hope this helps
Answer:
- Diploid → Prophase, metaphase, and anaphase
- Haploid → Telophase
Explanation:
During prophase I, chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n
During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n
During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n
In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n
Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.
The two new cells are ready for meiosis II.
The correct answer is - the variable.
With the experiment, in the way that Dan had decided to perform it, the fertilizer is the variable, as in one of the parts with strawberries he uses fertilizer, while in the other part he doesn't uses fertilizer.
While this kind of experiment may give Dan some answers, and he might notice differences, still he would have to be more detailed in the experiment to see for sure if the fertilizer is the thing that makes some of the strawberries grow better than the others.
Dan should also put all of the strawberries at places that would receive the same amount of light, experience the same weather conditions, receive the same amount of water, and to be planted in a soil of the same quality. Only like this, after putting the fertilizer, Dan can now if it makes any changes or not.
