A researcher is culturing cells in a petri dish. After a few weeks, she notices that these cells have formed a "sheet," with junctions visible between individual cells. All of the statements are true regarding these cultured cells except:a. These cells have formed mesoglea.
b. These cells have formed an epithelium.
c. These cells have formed a structure similar to the epidermis or endodermis of jellyfish.
d. These cells may secrete enzymes or extracellular matrix proteins into their environment.
e. None of the answer options is false.

a. These cells have formed mesoglea.

Explanation:

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

explanation:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
