Answer:
Yes
Explanation:
Ectoparasite is an organism that lives and survive on its host. They are external parasite that live on the skin of their host.
B. Fleas are both ectoparasite and vectors of tapeworms.
Fleas lives on the body or skin of their host tapeworm or humans. Tapeworm are endoparasites that resides in human intestine. They survived by feeding and sucking the blood of their host. They are vectors because they transmit disease or are carriers of pathogens and eggs of tapeworm.
C. The three disease transmitted by ectoparasite to human are:
1. Malaria and this transmitted by female anopheles mosquito.
2. Sleeping sickness, it is transmitted by tse-tse fly.
3. Scabies, this is transmitted by mites.
Answer
They protect themselves
Explanation:
this through a range of techniques that allow for a plant to combat water shortages. A plant’s structural “armor” helps it to decrease the amount of water it loses to the environment and increase water storage. Plants respond to water shortages in very complex ways. These responses can include changes in the plants’ growth and in their ability to protect themselves against toxic chemicals that accumulate in the plant during dry periods. All of a plant’s responses are directly controlled by the plant’s genes. If we can understand the genes that are involved in protecting plants against drought, in the future we might be able to make genetically modified crops that can tolerate global warming and climate changes.
