As a substance absorbs heat the particles move faster so the average kinetic energy and therefore the Temperature increases. Temperature is a measurement of the average kinetic energy of the molecules in an object or system.
1.) what is the importance of understanding the structure and behavior of the subatomic particles of atoms?
- <u>we can find out how atoms combine and form many compunds</u>.
- <u>By learning about atomic structure, we can find out how atoms collide.</u>
- <u>By learning about atomic structure, we can find out why atoms do not have mass.</u>
2.) What is the importance of quantum numbers?
- <u>Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable location of the atom's electrons.</u>
- <u>Quantum numbers are also used to understand other characteristics of atoms, such as ionization energy and the atomic radius</u>
3.) What are the andvantages of usingdata/information using electron configuration?
- <u>T</u><u>he electron configuration of different atoms is useful in understanding the structure of the periodic table of elements. </u>
- <u>The concept is also useful for describing the chemical bonds that hold atoms together.</u>
Answer:
Cells from the cheek are a type of epithelial cell, similar to skin. ... They can be seen faintly even at 40x (scanning power), but the most dramatic images are at 400x where the nucleus is clearly visible as a dark spot in the center of the cell.
Explanation:
Answer:
Mutations leading to the better attachement of virus to the host cell would allow the virus to spread the infection and leave more progeny. The reproductive fitness of mutant viruses would allow the mutation to spread.
Explanation:
1. The organisms with same resource requirement compete with each other. Viruses are not living things but once inside the host cell, they behave like living things. Rapid multiplication of virus overpopulate the host cells.
2. Genetic variations are added to the viral progeny by random errors during replication of the viral genome. These random variations may impart beneficial trait, harmful feature or remain neutral. If a random mutation in the SARS-CoV2 virus allows it to adhere better to the cells of the respiratory system, the virus would be better able to infect these cells to spread the infection. Once inside the host cells, the mutant virus would leave more progeny. On the other hand, the wild type virus that lack this mutation would have lesser chances of entering the host cells and may or may not replicate.
3. The progeny of the mutant virus would compete better with the non mutant ones due to the presence of same mutation.
4. Differential reproduction and more progeny of the mutant virus would spread the mutation among the virus.
