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.

r=1PdPdt=μ−
Hope this helps
The answer you chose is correct becAuse if both parents are heterozygous for a disease that is recessive there is a 25%chance of the offspring inheriting the trait.Ex:
R r
R (RR) (Rr)
r (Rr) (rr) rr is the only outcome that can inherit the disease.
Answer:
in my knowledge
Option B: X
Explanation:
Plant cells have certain features, including chloroplasts, cell walls, and intracellular vacuoles.
Photosynthesis takes place in chloroplasts;
hence, X is your answer
A. soil type and structure
b. soil porosity
Answer: The environment might affect the population, because there might be more predators in one area compared to another
