Answer:
Option c (No, T cells left from the previous infection can kill any virus.
)
Explanation:
When ever viral infection occur, body's immune system start to fight against it by activating B-cells and T-cells.
B-cells produce antibodies that bind with virus and act as label. This label indicate virus as foreign substance. Hence T-cells recognize it and kill it. Furthermore, B-cells form memory cell that keep the viral memory. if this viral infection occur again in future, T-cell recognize it and eliminate the virus.This mechanism is called immunity.
Answer:
11. The behaviors and physical characteristics of species that allow them to live successfully in their environment are called adaptations.
Explanation:
Adaptations <em>are a process that organisms go through to become better suited for their environment to help them be better suited to survive.</em>
Answer:
- sporangia , zygospore
- Basidiomycota
- hyphae, mycellium
- lichen
- mycorrhiza
- Ascomycota
Explanation:
1. Zygomycetes reproduce asexually through the haploid spores formed in sporangia, or sexually through diploid nuclei formed in zygospore.
2. Basidiomycota are called club fungi because they produce club-shaped reproductive structures like toadstools.
3. The vegetative body of most fungi is called a hyphae, which consists of an interwoven mass of threadlike filaments called mycelium.
4. A lichen is a symbiotic association between a fungus and a single-celled alga or cyanobacteria. The fungus protects the photosynthesizer from harsh conditions while consuming the extra nutrients it produces.
5. A mycorrhiza is a symbiotic association between a fungus and the roots of a plant. The fungus receives energy-rich sugar molecules produced by the plant while passing minerals and nutrients from the soil to the root.
6. Ascomycota, also known as sac fungi, include morels, yeasts, and the species that produces penicillin.
