The Salinity of a small inland lake has recently started to increase. Researchers are planning to study the lake over several decades to investigate how freshwater organisms survive significant changes in their natural habitat. Which of the following physiological mechanismus will the researchers most likely observe amonth the surviving organismus in the lake?

a. Prokaryotic organismus will use various menchanismus to counteract swelling of cells as a result of increased water uptake.

b. Single- celled organismuss will use various mechaismus to counteract the increased flow of water from cells to the entvironment.

c. Eukaryotic organismus will use various mencahismus to counteract the diffusion of positively charged ions across the cell membrane.

d._ Eukarytic organismus will use mechanismus to counteract diffusion of swelling of scells charged ions of increased water uptake.

e.) Multicellular organismus organismus will use various mechanismus to counteract the loss of cell adhesion as a result of calcium deficiencies.

Option-B

Explanation:

The organisms which live in the extreme saline conditions are called the halophiles. The halophiles are considered the extremophiles as they live in the extreme condition on Earth.

The organisms which live in the saline conditions have the physiological mechanism which can counteract with the increased flow of water from the cell to the environment. The increased flow of water can interfere with the other physiological process of the organisms therefore the bacteria have the mechanism which can counteract the increased flow of water.

Thus, Option-B is the correct answer.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."    

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
