Answer:

A. City A because there are no pollution sources upstream.

Explanation:

Water pollution is th contamination of water. There are many means through which water is contaminated such as industrial waste, agricultural waste and domestic waste et-cetra.

City A and City B get water from sunset lake and moth lake which have factories (industrial waste) and farmland (agricultural waste) nearby them, which are responsible for the contamination of river water. due to this cities can recieve contaminated water which can affect their health.

But the quality of water in City A will be best than that of City B because according to the image, City A do not have nay upstream soooooource of pollution, as factories and farmland are located at downstream.

What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla?
VMariaS [17]

Answer:

Option C, shared DNA sequences

Explanation:

Complete question -

What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla?  

- shared patterns of development

- shared morphology

- shared DNA sequences

Solution

Vertebrates have true backbone while invertebrates lack true backbone. Among the invertebrates, the echinoderm phylum is closely related to vertebrates as the echinoderm possesses notochord (similar to backbone) during their early stage development which disappears later.  

Through the genomic sequence studies it has been found that echinoderms are similar to vertebrates in many ways. Echinoderms have diverged from deuterostomes along with human and hence pose some genetic similarity  which can be devised through study of common DNA sequences

Hence, option C is correct
