The best way to reduce wind erosion on farm is to plant ground cover in unused fields.

Explanation:

  • Wind erosion is defined as the removal of the top soil from unused barren land by winds.
  • This results in degradation in the soil fertility and renders it unproductive.
  • Roots of plants bind soil particles.
  • Planting ground covers like herbs , shrubs and wild plants on unused land will prevent the exposure of the top soil to the eroding agents and reduce erosion.

geniusboy [140]
All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells. Unlike bacteria, most viruses do cause disease, and they're quite specific about the cells they attack.

Answer:

<em>B and C.</em>

Explanation:

The epidemiological triangle is an illustration of interaction among suitable hosts, disease agents, and the environment that drives successful outbreak of diseases.

In order to successfully tackle or reduce the incidence of a disease, the triangle has to be broken.

<em>In the case of malaria which is caused by plasmodium but spread through the female anopheles mosquito, one way of breaking the epidemiological triangle is to eliminate female anopheles mosquito in the environment using any possible means. This will stop the spread of the parasite and hence, the disease.</em>

<em>Another way to reduce/prevent malaria is to prevent the vector, female anopheles mosquito from getting to the host, the human populace. This can also be achieved by several possible means.</em>

Relocating the entire village to a neighbouring village might not break the epidemiological triangle as long as female anopheles mosquito still abounds. In the same vein, antibacterial drugs will not help to treat malaria. However, instructing residents on personal protective measures and controlling the vector through chemical larvicides will go a long way in breaking the triangle and reducing the incidence on the malaria disease.

<em>The correct options is B and C.</em>

Lana71 [14]

Answer:

The answer to 1. is option a. asexual portion.

The answer to 2. is option b. sexual portion.

The answer to 3. Is option a. Mosquito

Explanation:

1. The asexual portion is the stage in the Plasmodium erythrocytic cycle where the parasite develops in the erythrocytes causing accumulation of waste and toxic substances which ultimately end up in the bloodstream when the infected cells lyse. These factors acts to produce the symptoms experienced in malaria.

2. During the sexual portion of the Plasmodium cycle spores formed in the human host are released into the bloodstream which is usually picked up by an uninfected female anopheles mosquito when it takes a blood meal.

3. An infected mosquito passes the sporozoites to a new human host when it takes a blood meal and the cycle starts all over.
