Answer:
rooting depth
Explanation:
The need for water of plants is determined by the degree of soil moisture. The optimal soil moisture for most vegetable plant species is between 70 - 90%.
When the soil moisture is below 60%, most plants show a symptom of lack of water in the form of sports development of plants, flowers, and fruits fall off, while excessive watering can lead to rot of the plant or the plants have a lush increase, they become thin…
Important:
It will not affect the american ecosystem in one single way. There are many stuff that will change due to global warming, not only in America.
___________________________________________________
Here's some information:
- Global warming can raise sea levels by melting glaciers - that can affect North-America since it stands relatively close to the North Pole.
- Living organisms have adapted to live under certain conditions, and if those conditions change too rapidly, we'll see many things going on. Plants can start dying-out, which means all the other animals will die-out as well.
- An increase in water temperature might affect the water cycle, since more water will evaporate in the surface, and we don't know if the condensation of water will be able to keep up.
- Dry and hot regions will get even drier and hotter, and that's not something we want in the hot and dry southern regions of North-America.
- Ice/snow is important in the ecosystems that have it. It forms part of a cycle that can cause a lot of trouble if broken.

Now, if we apply all those consequences and many others to the whole world, the only conclusion with can get to is that every day that passes and we don't do anything, is a day less until our extinction. If things aren't done seriously, Mars is not a salvation option, nor is the Moon or any other place we've been exploring.

Answer:
d. Ribosome
f. Cell wall
Explanation:
In humans 80s type of ribosome is present and in bacteria 70s type of ribosome is present. Human cells do not have cell wall while bacterial cells have peptidoglycan cell wall. These differences can be targeted by the potential antibacterial agents.
For example, tetracycline antibiotic inhibits the binding of important molecules to bacterial ribosome which ultimately inhibits the protein synthesis in bacteria. Vancomycin antibiotic on other hand inhibits the cell wall formation in bacteria by inhibiting peptidoglycan synthesis.
Answer:
AN hypothesis can tested through experimentation and it can also be tested through deductive methods
In a science experiment only one variable is changed the independent variable to test how this changes the dependent variable
3 a variable that is observed or measured during an experiment is called the dependent variable- d
