This statement is true because cells have the capability to divide.
Answer:
Plants use electric fields to communicate with bees, scientists have learned.
Bumblebees are able to find and decipher weak electric signals emitted by flowers, according to the study.
Tests revealed that bees can distinguish between different floral fields, as if they were petal colours. The electric signals may also let the insects know if another bee has recently visited a flower.
Explanation:
How bees detect the fields is unknown, but the researchers suspect the electrostatic force might make their hair bristle. A similar hair-raising effect is seen when placing one's head close to an old-style TV screen.
Flowers were already known to use bright colours, patterns and enticing scents to attract pollinators.
By using the legend below the diagram, you can assume that Phase 1 indicates that meiosis has occurred because of the color of the arrow. The dark gray indicates haploid, and haploid is the result of meiosis. Diploid is the result of mitosis.
Another indication is the presence of sex cells or gametes in Phase 1. Meiosis produces gametes and in phase 1, you can see that egg cells and sperm cells were produced.
