The stars Spica and Antares have approximately the same apparent magnitude as seen from the Earth. This means that -
A. Spica and Antares are about the same distance from the Earth
B. Spica and Antares are about the same size
c. if Antares is bigger than Spica, then it is farther away
D. if Antares is farther from the Earth than Spica, its luminosity is greater than Spica's

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.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.

idk what happened..you tell
