The most basic difference is that sea ice forms from salty ocean water, whereas icebergs, glaciers, and lake ice form from fresh water or snow. Sea ice grows, forms, and melts strictly in the ocean. Glaciers are considered land ice, and icebergs are chunks of ice that break off of glaciers and fall into the ocean.
I believe the correct answer from the choices listed above is the first option. <span>The biodiversity and distribution of penguin species in the Antarctic Peninsula are changing as sea ice disappears. This is caused by the climate change which causes glaciers to melt down rising the sea levels. Hope this answers the question. Have a nice day.</span>
Answer:
The problem will be because:
- <u>The error in the construction of the bridge will be actually 40 cm</u>.
Explanation:
When you, as an engineer, listen about a scale 1/20, it means that for each 1 cm in the model, it will be 20 cm in the real footbridge (20 times upper to the scale model), then how the error in the model is 2 cm, the real error is 40 cm, in this case, imagine that you didn't know that the bridge will have an error of 40 cm, which is approximately 1,31 ft, <em><u>from a side of the bridge you begin with the correct measure, and the other side you use the measure with the error of the 40 cm, the result is that when you going to finish the bridge in the center, this won't match, making more expenses to correct that big error</u></em>.

Explanation:
Cyanobacteria also known as blue-green algae, they are heterogeneous group of photosynthetic prokaryotic organisms. Like prokaryotes such as bacteria, cyanobacteria lack endoplasmic reticulum, mitochondria, membrane bound nucleus, and Golgi apparatus. Bacteria are simpler than other organisms, and single celled microbes.
Both bacteria and cyanobacteria reproduce through the asexual method either by binary fission in unicellular, multiple fission in colonial form or by spore formation, and fragmentation in filamentous species.
