Answer:

two sets of magnifying lenses

Explanation:

This is because a compound microscope is a high magnifying microscope that have multiple lenses or two magnifying lenses which help to see or observe or magnify image very well compare to single lense. It is a high power microscope and it has high level of magnification because of the

two magnifying lenses. It produces two dimensional image. The eyepieces and the objective lenses give a very high magnification, a condenser that is below the stage focus the light into the specimen to be viewed.

Why phytoplankton biomass decreases between June and July​
timurjin [86]

Answer:

The cause of phytoplankton blooms has traditionally been attributed to seasonal changes in ‘bottom-up’ environmental factors controlling phytoplankton division rates, such as nutrients and light 3,4,5,6,7. However, seasonal changes in phytoplankton biomass (P) represented by the biomass-specific net rate of change (r) always reflect the interplay between two dominant terms, the phytoplankton division rate (μ) and the sum of all loss (l) rates (e.g., grazing, viruses, sinking):

Explanation:

The photosynthetic production of organic carbon by marine phytoplankton plays a key role in regulating atmospheric carbon dioxide (CO2) levels, such that without this biological uptake it is estimated that present day atmospheric CO2 concentrations would be 200 ppm (50%) higher1. Phytoplankton blooms in the temperate and polar oceans play a disproportionally large role in ocean CO2 uptake, as well as being critical ecological events to which the migration patterns of marine animals, ranging from zooplankton to whales, have evolved2. The cause of phytoplankton blooms has traditionally been attributed to seasonal changes in ‘bottom-up’ environmental factors controlling phytoplankton division rates, such as nutrients and light3,4,5,6,7. However, seasonal changes in phytoplankton biomass (P) represented by the biomass-specific net rate of change (r) always reflect the interplay between two dominant terms, the phytoplankton division rate (μ) and the sum of all loss (l) rates (e.g., grazing, viruses, sinking):

Why can't you put your hand through a solid table? Question 9 options: You cannot put your hand through a solid table, because t
Elenna [48]

You cannot put your hand on a solid table because the particles are close together and in a fixed position. This is because the atoms of a solid are not like liquid, gas, and plasma. The particles are too condensed to move around an opposing force.

How do flowering plants reproduce by fertilization if they are immotile?
Korolek [52]
Flowering plants reproduce by fertilization even if they are immotile by having their pollen be attached to the wings or bodies of other animals that touch them. This process is called animal pollination in which animals help to switch the genetics between different plants.
