Explain two ways in which scientists use fossils to determine environmental change
drek231 [11]
Hello.  Happy to help.

1)  Coast Lines:  The location of marine fossils can help determine where and when ancient coast lines were in the past.2)  Climates:  Fossils can be used to determine the past climates.  (Was an area cooler or wetter than the present.)

The presence of marine or land fossils indicates whether the land at one time was at the bottom of the ocean or not.

Also, you could mention radioactive dating and relative dating.  I am sure that is mentioned in your curriculum. 

Hope that helps.

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
AleksAgata [21]

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

How can you consider aquarium as an example of ecosystem?​
Daniel [21]

Answer:

An aquarium can therefore be described as a closed artificial ecosystem in which fish and plants are able to find a habitat where they can grow and develop in a healthy and balanced way. Each aquarium must therefore be consciously designed, developed and managed to facilitate the establishment of the virtuous cycles that occur spontaneously in nature and give rise to the interactions.

1. When “cleaning” a cadaver, what is removed to better see defined muscles?
Ad libitum [116K]

When cleaning a cadaver, a professional will remove the fascia in order to better see defined muscles.

The fascia is a thin layer of connective tissue that wraps muscles. It is membraneous and extends throughout the entire body. Among the many functions of the fascia are:

  • Protection
  • isolation
  • Compartmentalization

Of its functions, the last it's perhaps the most relevant to this question. It divided the muscles into groups. This is one of the main reasons that in order to see and properly study the muscles of a cadaver, the professional must remove the fascia.
