Answer:
for classifying organisms and studying biodiversity
Explanation:
The correct answer is tissue samples and cells.
The compound light microscope's main feature is the light source, so it is considered a bright field microscope. Invented back in 1595 by Zacharias Jansen, this type of microscope is still the most widely used type of microscope because of its price, but also because of its convenience with viewing bacteria colonies, browsing their movement, analyzing tissue samples, counting and analyzing the content acquired from smears, analyzing cells in a blood sample etc. Its magnifying power is from 4x to 4000x. Other structures which require larger magnifying power, are analyzed with an electron microscope.
Answer:
D) A and C
Explanation:
Gram staining is a laboratory technique used for bacterial species. It is used to differentiate between two groups of bacteria based on the components of their cell wall. Gram staining was developed by a scientist called Christian Gram in the year 1884. In the gram stain procedure, the following occurs:
- Due to the thick peptidoglycan component of their cell wall, GRAM POSITIVE bacteria retains the crystal violet due and stain VIOLET.
- On the contrary, due to the thin peptidoglycan component of their cell wall, GRAM NEGATIVE bacteria do not retain the crystal violet dye and hence stain, RED.
Based on this, a bacteria that has been gram stained has been tested for its GRAM REACTION and microscopic morphological characteristics, since it is a microbe.
Infiltration is the downward movement of water into the soil and runoff is when water flows above the surface of the soil
