Answer: no friction, metal
Explanation: yes
because they are both eukaryotic cells
The gravitational potential energy of Sara at the given height is 10594.8J.
Given the data in the question;
- Mass of Sara;
- Distance from ground;
- Acceleration due to gravity;
- Gravitational potential energy;
<h3>Gravitational Potential Energy</h3>
Gravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.
It is expressed as;
Where m is mass, h is height and g is acceleration due to gravity.
To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.
Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.

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
