Answer:
the dissolved oxygen of the water decreases.
the fish need the oxygen for respiration, breathing through their gills.
Explanation:
The salinity decreasing doesn't affect the pickerel, because it's a freshwater fish. no salt needed.
more light penetrating the water just means that more aquatic weed or grasses would grow, giving the pickerel more area to spawn their eggs.
temperature increase in the summer has no affect on the fish, since the spawning happens in late winter.
Cleavage lacks the growth phase of mitosis resulting in progressively smaller cells
Bacteria that change nitrogen gas from the atmosphere into solid nitrogen usable by plants are called nitrogen-fixing bacteria. These bacteria are found both in the soil and in symbiotic relationships with plants.
The correct answer is option I) Steroid hormones are lipid soluble and easily cross the phospholipid bilayer.
The steroid hormones are made up of steroid molecules, the steroid molecules are hydrophobic and lipid soluble. This property makes help the steroid molecule to cross the phospholipid bilayer membrane easily. The steroid molecule has a direct influence on the genome transcription, they act by binding with the DNA as a transcriptional factor.
