How do the structures of organims body be used as evidence of evolution?​

Answers

Homologous structures suggest that comparable selected pressures can produce similar adaptations, whereas analogous structures show that similar selective pressures can cause similar adaptations (beneficial features).
Similarities and differences among biological molecules (for example, in the DNA sequence of genes) can be utilized to assess the relatedness of species.

differences between the three classes of platyhelminthes​

Answers

Answer:

The phylum Platyhelminthes consist of three different classes: Turbellaria, Cestoda and Trematoda. Class turbellaria is composed of many free-living organisms, while some are parasitic. Trematodes are commonly known as flukes. They are parasitic flatworms with an unsegmented body.

Explanation:

The three classes of Platyhelminthes are Turbellaria, Cestoda, and Trematoda.

What are the differences between the three classes of Platyhelminthes?

Flatworms are members of the Platyhelminthes phylum. The Turbellaria, popularly known as planarians, the Trematode, usually known as flukes, and the Cestoda, also known as tapeworms, are the three classes that make up the phylum Platyhelminthes. Flatworm species come in more than 25,000 different varieties.

The four classes of Platyhelminthes are Cestoda (tapeworms), which are internal parasites of many vertebrates; Trematoda (internal parasites of humans and other species); and Turbellaria (free-living marine species).

Thus, these are the differences between the three classes of platyhelminthes.

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A balance between water withdrawn by evaporation and freshwater added by rivers and rain controls salinity.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.
