Answer:
B. processes to make them take longer than a human's lifetime
Mitotic division in onion root cells:
- Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
- Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
- Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
- Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.
Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.

Selective breeding makes use of existing, naturally present gene variants in a species? and the natural process of breeding. Genetic engineering involves a direct change to an organism's genome in the laboratory. Gene variants made through genetic engineering can be passed from one generation to the next.
Answer:
D if I'm D correct, or A maybe C, mostly D.
Answer:
Global climate models usually work by managing the planet as a set of connected boxes because this facilitates the management of the calculations applied in a climate system that is dynamic, variable and complex, which is due to the fact that there is not an equal pattern of climate in each area of the planet.
Explanation:
Climate models have been designed to show the dynamics of the planet's climate and what can be expected from the changes that occur in the future.
The scientific basis of a climate model is physical phenomena and chemical reactions to which a series of differential calculations are applied to determine the behaviour of:
- <em>Winds.</em>
- <em>Temperature.</em>
- <em>Relative humidity.</em>
- <em>Rainfall.</em>
- <em>Pressure changes.</em>
- <em>Heat transfer.</em>
- <em>Hydrological dynamics.
</em>
Global climate models usually divide the planet into sections -such as boxes- making the calculations in each sector, as well as the interaction of each section with the adjacent sections, which greatly facilitates making the differential calculations, showing the climate at a given time and making predictions of future climate behavior.
It is important to mention that a climate model also explains the changes that occur in the climate due to human activity, which is different in each region of the world.
