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.
In the context of the neural impulse, the membrane that encases the axon is called semipermeable because FLUIDS CAN SOMETIMES FLOW INTO OR OUT OF IT.
Semi permeability is the ability of the membrane to allow certain substances, not all, to pass through it.
Explanation:
Cuando se queman los fósiles, el carbón e hidrógeno reaccionan con el oxígeno produciendo dióxido de carbono (CO2) y agua (H2O). Durante esta reacción se produce calor. La electricidad se genera mediante la transformación de energía mecánica (calor) con energía eléctrica por medio de una turbina o generador.
Answer:
The correct answer is - Sustainable development.
Explanation:
Sustainable development is the process of using or utilizing the natural resources in the present in such an efficient way that there will be resources for future generations without compromising their needs.
It is essential in the current situation as people overexploiting the natural resources that it is quite possible there will very few resources will be left for future generations.
Answer:
a. sunlight reaches earth's atmosphere and is scattered in all directions by all the gases and particles in the air. blue light is scattered more than the other colors because it travels as shorter, smaller waves.
b. the hotter fire is the more the color changes. so blue fire means it's super super hot.
