What is salinity and how does it change?.

Answers

A balance between water withdrawn by evaporation and freshwater added by rivers and rain controls salinity. The Mediterranean Sea in Europe has a salinity of 38 parts per million or more. It's nearly cut off from the main ocean, and there's more evaporation than rain or additional freshwater from rivers.

Salinity is controlled by a balance between water removed by evaporation and freshwater added by rivers and rain. changes in evaporation and rainfall, ocean currents, melting ice, and freshwater influx from rivers or streams can influence patterns of sea surface salinity, making some regions saltier and other regions fresher over time.

What that determines if a cell is eukaryotic. *

Answers

To determine whether a cell is a eukaryotic or
prokaryotic cell, one can observe certain features.
If the cell in the question possesses a well-defined
or definite nucleus and have membrane-bound
organelles such as mitochondria, chloroplasts,
Golgi apparatus, endoplasmic reticulum, the cell is
eukaryotic. If the cell has nucleoid or indefinite
nucleus and without membrane-bound cell
organelles, the cell is prokaryotic. If ribosomes in
a cell are the 80S (S=Svedberg units) type, the cell
is eukaryotic and if ribosomes are 70S type then it
is prokaryotic.
there’s not any answer choices, but eukaryotic cells possess a clearly defined nucleus. they also have more organelles

The graph shows the change in seabird mortality rates in New Zealand waters due to illegal, unreported, and unregulated fishing (IUU) and the implementation of bycatch remediation measures in 2004. What conclusion can be made about the impact of the remediation measures that were used?

Illegal and unregulated fishing practices continue to cause increases in bird bycatch numbers, in spite of the new measures.
Legal fishing practices have caused the new remediation measures to become more effective.
The measures virtually eliminated all of the bird bycatch.
The measures used showed very little impact on the overall seabirds caught in fishing lines.

Answers

According to the graph, the measurements practically eliminated all incidental captures, as shown in the third answer option.

What does the graph show?Illegal capture practices show a high performance between 1997 and 2003.Illegal capture practices show a low performance from 2004 and this performance tends to fall in the next years until it presents very low values.Legal capture practices maintain a balanced performance.

The decrease in the performance of illegal practices from 2004 onwards, shows how the remediation measures were efficient in reducing the activity of these practices and providing a better environmental well-being.
