For photosynthesis to occur plants need sunlight water and carbon dioxide and chlorophyll. Through the process of photosynthesis plants cover light energy into chemical energy they use this energy to make food which they store as sugars
The right answer is mitosis.
Mitosis refers to the chromosomal events of eukaryotic cell division. This is a nonsexual / asexual duplication (unlike meiosis).
It also refers to a very particular stage of the eukaryotic cell cycle, called the "cell cycle", which is the stage of duplication of each chromosome of the mother cell and of their equal distribution in each of the two daughter cells.
Mitosis allows the formation of two daughter cells strictly identical genetically to the mother cell.
Answer:capturing energy help living organism autotrophs to convert inorganic carbon that is(CO2)to organic carbon (C6H12O6)which is required by living cell generally living organism for energy production
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.
Because if the new species is better at doing whatever the original species does, the original species can die because they are outcompeted by the new species, and because the new species is better, they can cause a further decline of for example the food supply that they're outcompeting the original species for. This can cause problems in the entire food web/ecosystem
