A Russian botanist and biochemist named Alexander Oparin came up with the idea that the first cells in existence might have formed from liquid droplet protocells. He assumes that the protocell can act naturally and form a container without membranes that is concentrated in chemicals
Answer:
26. Coal is burned at a power plant
27. In dams.
28. Gas heater.
29. Nuclear power plant.
Explanation:
Coal is burned at a power plant where Chemical energy is converted into thermal and then into electrical current. In dams, water falls from higher altitude in which Gravitational potential is converted to kinetic energy by revolving of turbines which produces electrical current. in heater, electrical energy is converted into radiant and also heat or thermal energy while the nuclear thermal energy is converted into electrical energy and this happen in the nuclear power plant.
Answer:
4N
Explanation:
Mitosis is the process whereby a cell duplicates or produces another identical copy of itself. The mitotic process, which occurs in four main stages produces two daughter cells that are genetically identical to the parent cell. For example, a diploid organism (2n) will produce two daughter cells with 2n from mitosis.
However, in a case whereby a plant cell (A) screws up mitosis during metaphase and pulls full copies of all chromosomes to one side. This would result in one daughter cell having 4n or tetraploid number of chromosomes. Ideally, mitosis separates the chromosomes equally into the two daughter cells to have 2n each. If one cell has all chromosomes, it means that cell will have all the 4n.
For example, in a diploid human cell with 46 chromosomes (2n). Mitosis should occur in such a way that each daughter cell will have a diploid 46 number of chromosome (2n). However, if all the chromosome ends up in one cell during mitosis, that cell will have 92chromosomes, which is 4n or tetraploidy.
Plants use energy from sunlight to turn water and carbon dioxide into an energy-rich sugar called glucose. This process is called photosynthesis, which means “making things with light”
