Star brightness is defined by either <span>D. apparent magnitude - when we measure it from Earth (that is how bright it is from Earth) - this is the closest to "basic observation" and the best answer
or by absolute magnitute - how bright it would be at a certain distance (this allows to compare the brightness).

The correct answer is D. Animal cell
Chromosome non-disjunction, anaphase lag and endoreplication
Answer:
Flat surface parallel to mesophyll walls position
Chloroplast assumed this position in condition <u>of low light intensities or optimum light intensities</u> for the reception of maximum amount of incident light. necessary for photosynthesis
Perpendicular to the incident light position.
During condition of <u>extreme high light intensit</u>ies chloroplast aligned in this position to avoid the loss of electrons from the chlorophyll from absorption of photons; (PHOTOXODATION.)
Basically photooxdation is a wasteful process which destroys the plants.
