How does prophase you of meiosis differ from prophase of mitosis?
a. chromatids do not separate at the centromere in anaphase I. b. centromeres do not exist in anaphase I. c. crossing-over occurs only in anaphase of miitosis
When does the nucleus reappear?
False, No it is the only phase where it disappears. It directly says it comes back in telophase but may be present during all other phases EXEPT prophase.
How does a tetrad form in prophase I of meiosis?
In prophase I, doubled homologous chromosomes group together to form a tetrad.
What can scientist infer from the similarties between these two structures?
We would need to know what the two structures are to respond to this question.
What two structures found in the skin aid in heat loss when the temperature of the body is high?
The two structures that are found in the body during heat loss are the hairs on our skin and the glands. The hairs trap more warmth that enters the skin and the glands of our body stash the sweat into the surface to reduce the warm feeling, and by this, it cools our body.
When does the nuclear membrane disappear during mitosis?
The spindle apparatus becomes visible after stage two of mitosis. (I'm trying to remember from biology class, so i could be wrong!)
During prophase what structures are held together by the centromeres?
The sister chromatids are held together by the centromeres. Each chromosome is made up of two sister chromatids.
Number of cells during prophase?
There is still only 1 cell during prophase.
What are the two tiny structures located in the cytoplasm near the nuclear at the beginning of prophase?
the centrioles =)
What are the two tiny structures located in the cytoplasm near the nuclear envelope at the beginning of prophase?
The centrosomes containing the centrioles. I assume you are speaking of animal cells.

The two small structures that separate and take up positions on opposite sides of the nucleus during prophase are the?
The centrosomes, which contain the centrioles in animal cells, not plant cells.
What cellular structures move to opposite ends of the cell during prophase?
It's the CENTRIOLES and their star-like radiating structures, called asters.This is Stage 1 in Mitosis:Chromatin in the nucleus condenses to form chromosomes. The pairs of centrioles move to the opposite sides of the nucleus. Spindle fibers form a bridge between the ends of the cell. The nuclear envelope breaks down.
During this phase of mitosis two centrioles appear to one side of the nucleus.?
prophase
During this phase of mitosis two centrioles appear to one side of the nucleus?
prophase
What is the phase that two new nuclear envelopes form?
In the Prophase. Nuclear envelope and nucleolus disappears.
