Amelia’s doctor says that she has a tapeworm. Which type of medicine is prescribed to Amelia?
antiparasitic
antibiotic
antifungal
antiviral

Answer 1

1) vascular tissue and seeds — both gymnosperms and angiosperms are vascular seed plants.

2) Flowers attract insects that transport gametes — flowers promote pollination by attracting pollinators.

3) The birth rate decreased, while the death rate increased — fewer births and more deaths cause a population decline.

4) Her memory cells recognized the pathogen and started to make antibodies — the vaccine produced immune memory that prevented disease.

5) antiparasitic — tapeworms are treated with antiparasitic/anthelmintic drugs.
