What is used to break the bonds of nodules??
olga_2 [115]
<span> </span><span>Bean roots will have no nodules if there are no compatible Rhizobium bacteria in the soil. The nodule is a symbiotic relationship between the plant and the bacteria. Nitrogen fixing root nodules are pinkish in color. Green root nodules indicate actively reproducing bacteria that are not fixing nitrogen. The number of nodules depends on the amount of innoculant (Rhizobium) available in the soil. Look at the photos and make an estimate like x nodules per y linear inches of root. Hope this helps.

The edible part of the radish root functions as a food storage organ. The string parts of the radish root function as normal roots absorbing water and dissolved nutrients. Bean roots have no modifications for food storage. Radish roots don't have nodules. The radish root is a "tap root". The bean root is a "fiberous root" 

Beans don't grown faster than radishes because of the root nodules. Bean seeds are large. Radish seeds are small. The energy stored in the bean cotyledons helps the seedling get a fast start. The radish gets a slower start from less stored energy.</span>

You inoculate two tubes of liquid culture medium with 100 bacterial cells and incubate one tube at 37°C and the other at 55°C. A
Nady [450]

Answer:

thermophile.

Explanation:

A thermophile is a kind of bacteria that belongs to the Archaea Domain and they are the kind of animals that can live in a region of high or extreme temperature. There has been a research on a kind of thermophile which is known as Methanopyrus kandleri which can exist in an extreme temperature of up to 500° C.

So, if we take a look at the question again we can see that after 48 hours and at 37°C 20,000 bacteria per milliliter are already in the tube and at more higher temperature of 55°C we have 1,568,000 bacteria per milliliter which means that at higher temperature more of the bacterial is produced.

•Address the letter to the editor of a local newspaper.
Julli [10]

The answer is; hydrothermal, geothermal, and wind

Hydrothermal, taped from the biggest river on the state contributes approximately 60% of the energy in the state. Geothermal is second,approximately 30% while wind power contributes approximately 10%.


The costs of the electricity in the state are relatively cheap compared with states whose main source of energy is hydrocarbon fuels.   Geothermal power is the cheapest (even though initial investment is prohibitive). Hydrothermal is slightly expensive than geothermal due to the maintenance required and also  is prone to fluctuations of the river regime. Winds are also cheap but initial investment if the wind farm is high.



Hydrothermal energy has the biggest environmental impact compared to the other two. Due to the walls of the dam on the river, migration of some aquatic species is impeded. The reduced flow of water (and sediments) downstream of the dam also impact these ecosystems. Geothermal and wind energy sources have a very minimal environmental impact on the environment .


The state could increase electronics with low power consumption (such as LED lights) in the market for availability to the population. This would be followed by a sensitization campaign on the ideal use of power in the household to conserve power when not in use.

Describe how the structures of proteins differ from the structures of carbohydrates (150 words)
Veronika [31]

well both are considered macromolecules. proteins are like big lego construction. each single piece gets pieced together to make a larger thing. each single piece is a monomer, and the larger construction is the polymer. the monomers are called amino acids and they get pieced together to form the polymer which is called a protein. the linkage that they use is an amide bond, and in biology it is usually called a peptide bond. carbohydrates can be singular monomers or polymer units. they are made of completely different compounds usually aldehydes or ketones. and they link together through different chemical linkages (acetal or ketal linkages for polymers, hemiacetal or hemiketal linkages for monomers). both can be large, 3D strucutres proteins are only functional as a large, 3D structure, while carbohydrates can be singular. (you might wanna word it differently for safety reason)
