Brine shrimp live in salt water, but the level of salt in the water where they reside can differ dramatically from day to day or
Naily [24]

Answer:

The correct answer is "excretes; hypotonic; absorbs, hypertonic".

Explanation:

Cell's homeostasis is only conserved in an isotonic solution, since cells that are in an hypertonic solution (high salt concentration) tend to loss water, and in hypotonic solution (low salt concentration) tend to absorb water. Brine shrimp lives in waters that are both, hypertonic and hypotonic and has adapted to overcome this issue by excreting and absorbing salt across its gills. In very high salt concentrations, a brine shrimp "excretes" salt across its gills and maintains an internal salt concentration that is "hypotonic" relative to the water where it lives. In lower salt concentrations, a brine shrimp "absorbs" salt water across its gills and maintains an internal salt concentration that is "hypertonic" relative to the water where it lives.

kompoz [17]

Answer:

b- It is a spontaneous process.

Explanation:

Passive transport is the type of transport of substances across the plasma membrane that occurs without energy expenditure and occurs spontaneously. There is no energy expenditure during passive transport because substances naturally move from the more concentrated to the less concentrated medium, ie in favor of the concentration gradient.

Substance transport occurs until concentrations inside and outside the cell are equalized.

According to this conceptualization we can conclude that the correct answer to your question is the letter B.

What do scientists use to mark boundaries in the geologic time scale?
tekilochka [14]

Era is used to mark the boundaries of geological time scale by using radio carbon dating technique.

Explanation:

Geological time starts with Precambrian time.

Geologically, time is divided between the Precambrian era and present time into era.

The three eras are Paleozoic era, Triassic period and Cenozoic era.

Era is further divided into periods.

Scientists use radio carbon dating to study fossils and rock formation. With this study they were able to divide them in exact geological scale.

Geologic scale is the record of events in earth's history and evolution.
