Eukaryotic cells and prokaryotic cells contain a cytoplasm and ribosomes. Eukaryotic cells have organelles and a nucleus.
Prokaryotic cells were most likely to evolve first because of the simple structure.

Hey there! :)
Baltic sea has brackish water because of the large amounts of runoff
Brackish water has more salinity than fresh water but less than that of seawater.
Answer:
In roots, the vascular tissues, i.e., xylem and phloem, are found in the central vascular cylinder, while in stems these tissues are dispersed throughout the stem, generally arranged as a ring towards the outside of the stem (epidermis)
Explanation:
Vascular plants have two different transport tissues: xylem and phloem. The xylem transports water from roots to stems and leaves, while the phloem transports food (i.e. dissolved sugars) from the leaves to all parts of the plant. In roots, vascular tissues form a central core in order to withstand stretching forces. Moreover, in stems, vascular tissues are dispersed (generally concentrated towards the epidermis), in an arrangement that enables them to resist compression and bending forces.
Answer:
Two countries with a very similar gdps can have great difference in the average material well being when the two countries have wide difference in their population and in their national debts.
Explanation:
The Gross domestic product of a country shows the overall asset a country has without removing the national debt. This average wellbeing if the citizen in a country depends on the per capita income of that country, the higher the PCI the better is the expected wellbeing. The cpi is calculated by dividing the gdp by the population in the country, therefore even when two countries have the same gdp, but very huge difference in their population, it will lead to different per capita income. The country with the smaller population will have higher per capita income and better material wellbeing.
Secondly, when the countries have the same gdp and population, the difference in their national debt will lead to difference in available material wellbeing in the countries.
