What is a european starlings ecological role
makkiz [27]
European Starlings have a significant impact on their environment because they congregate in such large numbers.  They probably play a role in seed dispersal because of their consumption of a wide variety of fruits.  European Starlings also control some insect populations, but since they will eat almost anything they cannot be relied upon to eat only pests.  Insects they are known to feed on include the larvae of craneflies (Tipulidae) and moths (Lepidoptera) as well as mayflies (Ephemeroptera), dragonflies and damsel flies (Odonata), grasshoppers (Orthoptera), earwigs (Dermaptera), lacewings (Neuroptera), caddis flies (Trichoptera), flies (Diptera), sawflies, ants, bees and wasps (Hymenoptera) and beetles (Coleoptera).  They will also eat small vertebrates such as lizards and frogs, as well as snails (Gastropoda) and earthworms (Annelida).  European Starlings have a particular technique of inserting their closed bill into the ground or an object and then prying the bill open, creating a small hole.  This allows them to forage efficiently in soil and among roots as well as in feed troughs and on the backs of ungulates where they search for ectoparisites.

If a hypothetical cell contained 1% saline and 5% glucose, approximately what
liraira [26]

The hypothetical cell will approximately contain 94 percent (94%) of water.

  • If a cell is placed in a hypertonic solution that contains more concentration of solutes (such as salt and glucose) than the cell, then it will shrink because water moves outside the cell.

  • If a cell is placed in a hypotonic solution that contains more concentration of water than the cell, then the water will move inside the cell.

  • Finally, if a cell is placed in an isotonic solution, which contains the same concentration of solute and solvent as outside the cell, there will be no change in the cell and the solution.

  • In this case, the percentage of solutes is equal to 5% (glucose) + 1% (salt) = 6%, so the remmaining porcentage of water is equal to 94 percent (94%).
