Mitosis is conventionally divided into 5 phases, which include prophase, prometaphase, metaphase, anaphase and telophase and cytokinesis.
Interphase
Before coming into mitosis, a mobile spends a length of its increase underneath interphase.
Prophase
Prophase straight away follows the S and G2 levels of the cycle and is marked by way of condensation of the genetic fabric to form compact mitotic chromosomes composed of chromatids attached at the centromere.
Prometaphase
In the prometaphase, the nuclear envelop disintegrates. Now the microtubules are allowed to extend from the centromere to the chromosome.
Metaphase
At this level, the microtubules start pulling the chromosomes with equal pressure and the chromosome ends up in the center of the cell. This area is referred to as the metaphase plate.
Anaphase
The splitting of the sister chromatids marks the onset of anaphase. These sister chromatids end up the chromosome of the daughter nuclei.
Telophase
The chromosomes that cluster at the two poles start coalescing into an undifferentiated mass, because the nuclear envelope begins forming round it.

Answer:
C = 39%
H = 5.43%
Explanation:
Firstly, we calculate the number of moles of each.
For carbon, we use carbon iv oxide
Mass here = 0.636g
Number of moles of carbon iv oxide = mass of carbon iv oxide ÷ molar mass of carbon iv oxide. Molar mass = 44g/mol
Number of moles = 0.636 ÷ 44 = 0.014mole
Since 1 mole of carbon iv oxide contains 1 mole carbon, 0.014 mole of carbon iv oxide is also produced.
Mass of carbon = 0.014 × 12 = 0.173g, where 12 is the a.m.u of carbon.
For hydrogen, we use water .
Mass of water = 0.220g
No of moles of water = 0.22 ÷ 18 = 0.012 mole
1 mole of water has two moles of hydrogen, thus the amount of hydrogen produced = 0.012 × 2 = 0.024mole
Mass of hydrogen produced = 0.024 × 1 = 0.024g
The percentage composition are as follows:
Carbon = 0.173/0.442 × 100 = 39%
Hydrogen = 0.024/0.442 × 100 = 5.43%
Answer:
Explanation:
Which is more reactive hydrogen or oxygen?
Hydrogen is not particularly reactive. For example, just mixing hydrogen and oxygen gas will not cause a reaction at room temperature, but many metal elements oxidize at least on the surface in air. ... It is combustible because oxygen wants electrons and takes them from hydrogen to form water.
Stable if they have a full outer shell. 8 electrons in their outer shell
