Me with this (biology) 23 serious answer suppose a woman with type o blood and a man with type ab blood have children. what are the children's possible genotypes?

This would be the most reasonable

O + AB = Any A blood type/phenotype

→ A and B are codominant, and O, although it's not recessive, it's less dominant. The image below might help you understand the dominance and result of blood combinations.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
