It has organelles called contractile vacuoles that continually eliminate the excess water gained through osmosis. Knowing that Paramecia gain water through osmosis, we can deduce that they normally live in ice and very cold environments. the ocean. very salty environments. freshwater lakes and ponds.

Answer:

The correct answer is freshwater lakes and ponds.

Explanation:

Paramecium refers to a single-celled species that generally thrives in fresh water like lakes and ponds and relies majorly upon bacteria as the source of their nutrition. They exhibit tiny hair-like projections on the exterior part of their body that helps them in locomotion. Apart from this, as an essential form of adaptation, these species exhibit contractile vacuoles that help them to eradicate excess of water that they gain from their surroundings by the process of osmosis.  

These contractile vacuoles help in maintaining the pressure of water within the body of paramecium by contracting continuously as it helps in discharging excess of water into the surroundings. The presence of contractile vacuole plays an essential role in the life of paramecium as in case if the concentration of salt becomes high in the surroundings in comparison to the concentration present within the body, the organism would die. Thus, it can be concluded that these species thrive in freshwater lakes and ponds.

PLEASE HELP. WILL GIVE BRAINLIEST. What role do decomposers play in an ecosystem? Be sure to refer to the biogeochemical cycles.
iren2701 [21]
Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.

A protein has been used by comparative molecular biologist to show the evolutionary path of how organisms did what things in reg
Anit [1.1K]

Answer:

Cytochrome C; it provides evidences that there is similarities in the respiratory pathways for producing ATPs by  all living organisms especially mammals.

Explanation:

Cytochrome c is located in the intermembranes of mitochondria, and it functions in the transfer of  of one electron in electron transport chain,(ETC) needed for  generation of proton motive force;  for generation of energy in the synthesis of ATPs by ATPase synthase  during chemiosmosis. Its allows oxdation-reduction by the switching of its iron ii to iron iii. during electron transports.However its iron atoms does not undergo oxidation with  oxygen. This feature makes it stable and  an ideal carrier of electrons.

Its amino acid sequences is very similar in all living organisms especially  between mammals(e.g man and chimpanzees)with little variation in few amino acid residues due to mutation.This similarity in its amino acids sequences in all  living  organism together with small molecular size makes it ideal  molecular evidence  for studying comparative molecular evidence of  evolution.

This is because it can be used  to trace  the pathways of respiration to synthesize energy, and therefore to conclude that  most  organisms share common ancestry, since a very similar protein sequence in  a structure(Cytochrome c) participated in unique ETC mechanisms  in all, needed for energy synthesis .

Anni [7]
These lines (there is four of them) are residuals of the fusion of the five sacrum vertebrae that are fused. These "vertebrae" or segments present a characteristics, being the first of them very similar to a lumbar vertebra, large, and the other vertebrae are<span> progressively smaller and flattened. They also present a curved shape being anteriorly concave.</span>

In early pregnancy, what hormone stimulates growth of the corpus luteum? human chorionic gonadotropin follicle-stimulating hormo
disa [49]
Human chorionic gonadotropin (hCG) is secrete by the embryo early in pregnancy to keep the corpus luteum for dying. This positive feedback will maintain the corpus luteum, which secretes Progesterone and Estrogens throughout pregnancy, in order to keep the endometrium well to nourish the embryo/fetus.
