Which phase of mitosis is shown in the diagram
Lorico [155]

If there's this picture in the question, the right answer is metaphase.

A metaphase qualifies a phase of meiosis or mitosis (following prophase and preceding anaphase) during which chromosomes, or at least kinetochores, align with the equatorial plate of the spindle. At this stage, chromosomes are at their maximum condensation and karyotypes are usually established. In the first division of meiosis, the metaphase represents the phase during which meiotic analysis is usually accomplished.

Read the Mungo Lady and Mungo Man Do others in the field of anthropology agree with Dr. Thorne's view? Explain.
sweet [91]
I've read the story back a couple months ago

Actually, there are many archeologists and anthropologists disagree with dr. Thorne's view. Basically, Thorne strongly believes that what many calls Homo erectus was, in fact, Homo sapiens, and that they migrated out of Africa almost 2 million years ago and dispersed throughout Europe and Asia. That would actually be very different from what scientists have always believed about the evolution of the species. That is why many of them are against him)

I hope I helped :)

Retrieve your plant specimens. If you have an Edmentum lab kit, your specimens are a cork section, Zea
Tcecarenko [31]

In the plant, when a cell divides into two daughter cells, we observe in this experiment Mitosis, which is the cell division that allows the plant to elongate and occurs in the meristematic tissues that are at the ends of the plants. Whereas meiosis is restricted to reproductive tissue and forms gametes that will form new seeds through fertilization, carrying genes from one generation to another.

<h3>How does mitosis occur in plant cells?</h3>

In plant cells, division takes place from the inside out – centripetal cytokinesis. In plant cells, cytokinesis is centrifugal, from the outside to the inside: there is the formation of a lamella, which grows from the center to the periphery and separates the two cells.

With this information, we can conclude that through successive mitotic divisions that the zygote (cell generated after the meeting of gametes) manages to originate all the cells of its organism. Mitosis, therefore, is responsible for the growth and development of embryos.
