Let us look at the what, why and how of studying extreme places like the deep earth and the deep space. Scientists need to figure out as to 'what' they want to look at such places, be it a new exotic creature or bio-genesis (birth of life). Unless there are several testable hypothesis constructed, such a study cannot begin. The 'why' aspect deals with the purpose of such research and expeditions. Is it of any use to the humans, or will it improve our current understanding of a phenomenon? The 'how' aspect deals with the technology and the economic assistance that can help in undertaking such a research. All these are the challenges that needed to be thoroughly considered to make such a research or expedition possible.
The dam acts as a barrier between upstream and
downstream. Dams are also built for
irrigation, but it is also deliberately destroyed in favor of irrigated
farming. Though it provides freshwater, and makes people be protected by
droughts, but it can also damage the agricultural resources by limiting the
water in some areas.
Answer:
The paramecium body.
Explanation:
1. The objective lenses on a compound light microscope doess have powers that start of as smallest to highest power, 4x, 10x, and 40x on the maximum power setting. This means that the sample can be magnified either, 40x, 100x or 400x.
At 40x magnification Stella will see organism 5mm.
At 100x magnification Stella will be able to see organism 2mm.
At 400x magnification Stella will be able to see organism more closely, 0.45mm, or 450 microns.
2. Paramecia are shoe shape or molded and almost transparent and shrouded in a defensive pellicle.
Pellicle capacities like skin and shields them from the components. For movement they have cilia.
Sugar production would stop meaning the plant doesn't have the needed nutrient to make food for itself causing another factor : photosynthesis to stop aka the plant would die and wither
Answer:
The last one and the second one
Explanation:
Both of those are technically correct. There must be a charge through the book before an electrical force can act on it. Id have to say the last one
