Answer:
Surface waves, S waves, and P waves can all be recorded by a single seismogram. However, they show up separately on the seismograph because they travel with different speeds.
Look at the seismograph below, and identify the surface wave, the S wave, and the P wave.
Drag the appropriate labels to their respective targets.
1. P wave
2. S wave
3. Surface wave
The S wave arrives 3 minutes after the P wave, so the epicenter is approximately_______miles away.
1250
The S wave arrives 1 minute after the P wave, so the epicenter is approximately________ miles away.
250
The S wave arrives 5.5 minutes after the P wave, so the epicenter is approximately_______ miles away.
2500
Drag the appropriate items into their respective bins. Each item may be used only once.
Hint 1. Epicenter distance
The distance in miles of the epicenter is shown on the map. It is also the horizontal axis on the graph.

14. Telophase 2
Explanation:
Following is a summary of the events of meiosis:
Interphase:
Prepares the cell for division. Duplication of DNA, duplication of centrioles occurs and the cell grows in size. At this stage the cell is diploid (2n).
Prophase 1:
First stage of Meiosis 1.The centrioles move to the poles of the cell, the nuclear membrane disintegrates, homologous chromosomes pair up (in the form of tetrad), form a chiasmata and then exchange segments of chromosomes with each other. This process is called crossing over.
Metaphase 1:
Involves the arrangement of the crossed over, homologous chromosomes on the metaphase plate which is sort of like a web of spindle fibers that originates from the centrioles.
Anaphase 1:
The tetrads arranged on the metaphase plate are pulled apart by the spindle fibers. This is the result of tension that build up in the spindle fibers as they grow towards opposite poles.
Telophase 1:
The last stage of meiosis 1. Involves the arrival of the chromosomes at the poles, the nuclear membrane starts to form and the chromosomes start decondensing. Telophase 1 yields 2 daughter cells with half the number of chromosomes as that in the parent cell.
Meiosis 2:
Meiosis 2 is exactly similar to mitosis. The only difference is that the haploid cells entering meiosis 2 do not duplicate their DNA. Meiosis 2 just involves the separation of the sister chromatids of homologous chromosomes.
- As mentioned above, interphase does not occur before meiosis 2.
- Prophase 2 involves the disintegration of nuclear envelope, centrosomes start moving to the poles.
- Metaphase 2 arranges the chromosomes on metaphase plate.
- Anaphase 2 separates the sister chromatids from the chromosomes.
- Telophase 2 develops the nuclear envelope and separates the nuclei of the daughter cells into 2. Nuclear division id followed by cytokinesis (division of cytoplasm). Telophase 2 result sin 4 haploid daughter cells with one chromatid from each chromosome.
It's helpful to study them together because it's important to understand how the structure (anatomy) of an organism is related to its function (physiology).
A cell uses the cytoskeleton to guide or group organelles
Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out . All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but plant cells only have the shapes of their cell walls. I don’t know if this is what u were asking but I hope it helps.
