Answer:
A pesar de algunas observaciones tempranas de bacterias y células, el microscopio impactó otras ciencias, especialmente la botánica y la zoología, más que la medicina. Importantes mejoras técnicas en la década de 1830 y posteriormente corregir la mala óptica, transformando el microscopio en un poderoso instrumento para ver los microorganismos causantes de enfermedades.
Explanation:
I would say AB. I really hope this helps. Have a blessed day.
When calibrating a spectrophotometer, measuring absorbance concurrently is the best option for a blank since it is proportional to the concentration.
Beer's law states that A = a b c, wherein there is the diffusion coefficient at a constant, b is the actual route length, & c is the concentration. Direct proportionality exists between b and c and absorbance.
Once the route length is doubled, incident light contacts double as many molecules in the solution. The consequence is a doubling of absorbance, which is equivalent to a doubling of molecule concentration.
There are two ways to detect chemicals using spectrum scanning. One approach involves turning the monochromator continuously with a stepping motor while gradually altering the wavelength connected to the output slit.
It is more practical to use diode array detectors. Up to a few hundred photodiodes may be incorporated into the chip that makes up this device.

Answer:
Explanation:
Taigas have few native plants besides conifers. The soil of the taiga has few nutrients. It can also freeze, making it difficult for many plants to take root. The larch is one of the only deciduous trees able to survive in the freezing northern taiga.
