Ascientist finds a new organism that may be either a bird or a bat, but it is not clear which group it belongs to. he is pretty sure that the organism has analogous structures with bats and homologous structures with birds, as suggested by genomic data. the organism has one trait that is shared with bats but not birds. which group should he choose for the new organism and why?

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

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.
