Yellow- Green Wavelength of light at peak absorption of 565nm.
Halobacterium is known to be a member of Archaea
and they thrive in very salty environment such as Great Salt lake and Dead Sea. Halobacteria under the process of photosynthesis
with chlorophyll and they make their ATP from the sunlight using bacteriorhodopsin
and halorhodopsin as photosynthetic pigments.
However, photosensory pigements found in
Halabacterium were:
1. photosystem 565 which is used to respond to yellow
–green light in other for cell to find optimum conditions for ATP synthesis and
photophosphorylation and they have peak absorbtion at 565nm.
2. Photosystem 370 nm appears to be responsible
for the protective avoidance of blue/UV light.
Hmm good question. Well I would have to test it for where there are no living life. I would have to build another NASA in the County because there is plenty of room there. Mars is made out of Dusty Crust that is about 30 miles thick. And let's say that the desert's Dusty Crust is about 5 miles - 15 miles thick. That will give about the same amount of surface that mars has. So we would know what to build for a perfect lander to work on Mars. This isn't much but it is something.
Answer:
Density is nearly 3 cabs per hectare
Explanation:
Given -
There are three three intertidal regions.
Area of each intertidal region is 
hectares.
Number of crab in the intertidal regions are as follows -
Intertidal region I - 7
Intertidal region I - 2
Intertidal region I - 6
Sum of crabs in all three regions is equal to
Total area of all three intertidal regions is equal to
hectares
Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions
Density 
Density is nearly 3 cabs per hectare
HCL is guilty for triggering the release of enzymes such as pepsin which are essential for the digestion of protein. Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine.
Answer:
A positive result.
Explanation:
Biuret test is a test performed to check whether proteins are present in a given sample or not. If the solution changes its colour to violet then it means that the sample contains proteins. If the colour is not changed to violet, then the result would be negative and protein would not be present in the sample.
Steaks contain a rich amount of protein. Hence, when Biuret test is performed for a steak solution, the results will be positive. The steak sample would change colour to violet.
