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
Answer: option C - The widespread use of antibiotics has led to resistant strains of viruses.
Explanation:
Antibiotics are substances (usually drugs) that can destroy or inhibit the growth of BACTERIA and similar microorganisms.
Do note that viral infection DO NOT respond to antibiotic treatment.
So, it is FALSE to say that the widespread use of antibiotics has led to resistant strains of viruses
<span>Adverse effects that are often associated with the use of adrenergics are anxiety, nausea, headaches, dizziness and restlessness. It is stated by the FDA that the drug should be used with caution in people who have heart disease, cardiac arrhythmias, or hypertension.</span>
