According to the photoelectric effect experiment , if the frequency of a specific light threshold frequency , what is the effect of increasing intensity of light on: VALUE OF PHOTOELCTRIC CURRENT?

the number of ejected electrons ?

the ENERGY of ejected electrons ?

If the frequency of the light was higher (green light, for example), then electrons were able to be ejected from the metal surface even if the intensity of the light was very low or it was shone for only a short time. This minimum frequency needed to cause electron ejection is referred to as the threshold frequency.

How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?   answer :   the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.
