It must be at least 4 bricks high because 6*4=24
2 bricks in each of the 4 levels of bricks (12*2= 24) (24*1=24)
4 bricks up*2 bricks wide= 8 bricks
A biome is defined as the large ecological area where the formation of plants and animals with common characteristics gather due to the similar climates. If I were an ecologist, and i will be determining whether an entire river and lake biome is being threatened by human activity, the indicator species that i might look for are the ones that have been introduced into the biome.
Because of the tectonic plates shifting it causes different landforms. Hope this helps!
Answer:
Devolution, the transfer of power from a central government to subnational (e.g., state, regional, or local) authorities. Devolution usually occurs through conventional statutes rather than through a change in a country’s constitution; thus, unitary systems of government that have devolved powers in this manner are still considered unitary rather than federal systems, because the powers of the subnational authorities can be withdrawn by the central government at any time (compare federalism).
Explanation:
Two statements support the claim that Jenner has been given credit for starting and spreading the practice of immunization:
- Jenner became interested in the protective effects of cowpox during his apprenticeship. Here, we are told that Edward Jenner started working on ways to defend the body against diseases as early as during his apprenticeship when he was a teenager. He had been told that farm workers who had contracted cowpox were immune to the smallpox epidemic which was spreading across Europe at the time. He then started working on a vaccine containing cowpox.
- Jenner made the first step to erase smallpox. This first step was to try his new smallpox vaccine on a child in 1796. The child did not catch smallpox. In order to get recognition and validation from the authorities, Jenner administered his vaccine to 22 more people, with success.
