Detailed explanation-1: -7 In the 1880s, Louis Pasteur developed a method of weakening viruses. The weakened viruses could be injected into healthy individuals. How is this method effective in fighting viral diseases? A The immune system develops antibodies in response to the weakened viruses.
Detailed explanation-2: -Which statement best explains why viruses can only reproduce within a host? Viruses lack the ribosomes necessary to make their own proteins.
Detailed explanation-3: -The organism which causes FMD is an aphthovirus of the family Picornaviridae.
Detailed explanation-4: -Which statement explains the most likely impact Caulerpa has had on the biodiversity in the Mediterranean Sea? The presence of Caulerpa within an ecosystem is an indicator of the ecosystem’s health. The spread of Caulerpa improved the habitat for many species of sea grasses, and increased the biodiversity.
Detailed explanation-5: -Viruses do not have cells. They have a protein coat that protects their genetic material (either DNA or RNA). But they do not have a cell membrane or other organelles (for example, ribosomes or mitochondria) that cells have. Living things reproduce.
