Answer is Communicable disease can be spread by inanimate objects, such as doorknobs.

The causal organisms of some of the communicable diseases are bacteria and viruses. The communicable diseases such as common cough and cold can be transmitted to a healthy person by indirect contact with contaminated substances such as food, air, soil, feces, equipment, objects including doorknobs, remote controller, etc.

Answer:

  1. Alaska
  2. Washington
  3. Hawaii
  4. California
  5. Oregon

Explanation:

Eruptions along the western edge of the United States have formed the Cascades volcanic mountain range.  Also, they develop island chains, such as the Aleutians in Alaska, which makes Alaska a potential volcanic eruption place. A prominent example of an eruption along the Ring of Fire was the dramatic eruption of Mount Saint Helens in Washington in 1980, which makes Washington a potential volcanic eruption state.  Deep beneath Hawaii, there is a fixed source of abundant rising magma, called a hot spot, making Hawaii likely to be a volcanic eruption state. In 2018, they added Salton Buttes to the 2018 assessment, which is a high threat of a volcanic eruption. In other words, California is likely to be a volcanic eruption state. Eleven of the eighteen very high threat volcanoes are in Oregon, and few other states, where explosive and often snow- and ice-covered volcanoes can project dangerous long distances to densely populated and highly advanced areas.

What did Allan Savory notice about the lands grazed by wild animals at the Africa Centre for Holistic Management
Shkiper50 [21]

Answer:

Allan Savory noticed that grasslands co-evolved with large numbers of migrating ruminants, and therefore are co-dependent on each other's survival. These animals grouped together and constantly bunched due to the predator-prey connection, eat the grasses following the seasons throughout their migration in arid regions (Brittleness scale, of Non-Brittle to Brittle environments).

As they move, they drop nutrient-rich dung and urine, while trampling organic litter (live or dead grasses, leaves, etc) and seeds into the soil. These actions break down materials into the surface, providing more covered soil and keeping materials from chemically decomposing (oxidation, as opposed to the fast biological decomposition that occurs in areas with consistent rainfall(Non-Brittle)). The true testament to his insights of Holistic Management re: grasslands is known as the 4th Key Insight: That time, rather than numbers governs over-grazing or over-trampling.

The important component here is that the time exposed to these animals plays the significant role in whether you have healthy grasslands, not the number of animals exposed to the area of consideration. The amount of "rest" (time) for grasses between eating or trampling is just as crucial as the time in an exposure.

Explanation:

Explained in his book and courses under "Holistic Management", by Allan Savory and Jody Butterfield, and Sam Bingham

abruzzese [7]

Answer:

well, providing extra protection from predators. Over time, the hare

Artic hares are commonly found in northern Canada and coasts of Greenland. Some are found in artic Europe and Asia. They are found on sea icing and are herbivore dependent on land plants for food. 20% mass part of their body is fat insulation and they are low climate animal. They dig into the ground or burrow under the snow during cold weather. It's a way to offer protection against the harsh weather and protection against predators. This is a form of behavioral selection.
