Answer:
At the end of<u> telophase II </u>and cytokinesis, there are four haploid cells.cells.
Explanation:
During telophase II the sister chromosomes separate from each other and move to the opposite ends of the cell. Once that the chromosomes are in the opposite ends, the cytokinesis starts, this is the division of the cytoplasm that will give two daughter haploid cells.
We have to remember that there will be four haploid cells because there are two cells, which are the result of meiosis I, that will go into meiosis II to give these four daughters haploid cells. Also, the phases in meiosis I and II are very similar. Both of them have prophase, metaphase, anaphase, and telophase.
Answer:
The correct answer is option 2. "Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano".
Explanation:
A seismometer is an equipment used by scientists to monitor ground's motion, including the earthquake activity that occurs beneath a volcano. These instruments are useful to predict if a volcanic eruption is imminent. By analyzing the length and strength of the ground's motion occurring during earthquake activity near a volcano, scientist could predict if an eruption is about to take place.
Answer:
Ferns
Explanation:
Ferns -
- These the species of plant , that are found in the shady and rainy areas .
- These classification of plant have a separate gametophyte, and sporophyte generations , where , the sporophyte is dominant .
- No seed plants .
Hence , the correct answer according to the information given in the question is , Ferns .
Answer:
A histone modification mechanism proliferate through a process that includes post translational modification procedure. The methylation, acetylation as well as ubiquitylation are one of the main modifiers that help in activation of silent genes and ultimately these covalently bonded histone modifiers help in regulating chromatin. The PTM has a main role in altering histone structure by these modifier's recruitment....
Answer:
The right answer is Letter A
Explanation:
The proposed model for the mechanism of initial transcription that suggests the entire RNA polymerase enzyme moves along the DNA is <em>transient-excursion model</em>, and the proposed model that is best supported by experimental findings is<em> scrunching model.</em>
<em>Because RNA polymerase leaves the promoter, translocate a short way along DNA template, synthesizes a short transcript before aborting transcript, releasing the transcript and returning to its original location on promoter. That is the transient-excursion model.</em>
<em>The scrunching model downstream DNA is pulled into the enzyme and has accumulated within the enzyme as single stranded bulges.</em>
<em>Experiments show that scrunching is right, experiments using single molecule analyses that allow the positions of different parts of polymerase to be measured relative to each other and to the template DNA during transcription.</em>
