Allotropes of carbon includes substances such as graphite, diamond or buckminsterfullerene.
They’re all similar in the thing that they’re all made out of carbon only.
However, their structure is different, such as graphite has a layer structure, diamond has a tetrahedral structure, and buckminsterfullerene has a spherical structure.
Since they have different structures, they have different physical properties too. For example, diamond is hard because all the carbon atoms in the structure is held together by strong covalent bonds, while graphite are graphene layers that are held by weak intermolecular forces which makes the layers slide over each other easily thus making graphite soft.
Answer:
Anaphase II.
Explanation:
Cell division may be defied as the phenomena by which the cell multiply and increases its number under the influence of cell cycle checkpoints. Two main type of cell division are meiosis and mitosis.
The meiosis result in the formation of four haploid cells from the single parent diploid cell. The Anaphase II of meiosis leads to the disjoin of the sister chromatids and the separation of chromatids. This is similar to the anaphase of mitosis.
Thus, the correct answer is anaphase II.
B, proton is positive and it does not represent the symbol
Answer:
Explanation:
An organism is a body which is made up of many organ systems and parts. Organs constitute these organ systems. Then we will notice that these organs are made up of different types of tissues. Tissues are further analyzed under microscope to see millions of cells. By increasing the magnifying power, we can see that the cells are made up of further small molecules called atoms.
So starting form atom leads to further steps and development steps, an organism is formed. Atoms combine to form cells and each cell in the body perform the same function as our body as a whole perform. No smaller components can perform important functions of body other than cells. That’s y cells are known to be as the fundamental unit of life.
