Answer:
Please look at the explanation section.
Explanation:
1) To calculate the yield of a protein in the purification step, the amount of protein produced must be divided by the amount of protein produced in the first step. The expression is as follows:
%protein yield = (Amount of protein/Amount of protein produced in the first step) * 100
If you have the purity percentage and the amount of protein produced, this formula could be used:
%protein yield = (Protein amount * Purity Percentage)/100
2) If this process begins with a cell culture and ends with the purification of Ni+2NTA. One method of increasing performance is to decrease the number of steps in the purification process. Because unfortunately, at each step of the purification of a protein leads to the loss of them.
all of them because they have to work together in order to do its job

Biomes
are very large ecological areas on the earth’s surface, with fauna and flora
(animals and plants) adapting to their environment. Biomes are often defined by
abiotic factors such as climate, relief, geology, soils and vegetation.
A biome<span> is NOT an ecosystem,
although in a way it can look like a massive ecosystem. If you take a closer
look, you will notice that plants or animals in any of the biomes have special
adaptations that make it possible for them to exist in that area. You may find
many units of ecosystems within one biome.
There are five major categories of biomes on earth. In these five, there are
many sub-biomes, under which are many more well defined ecosystems.

<span>The Desert Biom - Deserts
makeup about 20% of total land cover on earth and are characterized by
little (less than 50cm/yr) or no rainfall. Desert biomes come in four major kinds—
each of these having their unique features but have similarities in their
biotic and abiotic makeup. They are the Hot and Dry Deserts, Semi Arid
Deserts, Coastal Deserts and Cold Deserts, and within these are many
deserts located in many places of the world.</span>
The Aquatic Biome<span> - This
includes all water bodies on the earth’s surface. Aquatic biomes are grouped
into two, Freshwater Biomes (lakes and ponds, rivers and streams,
wetlands) and Marine Biomes (oceans,
coral reefs and estuaries). These biomes make up about 73% of the total
earth’s surface.</span>
The Forest Biome<span> - Forests
makeup about 30% of the total land cover on earth and are of incredible value
to life on earth. They are a
store of carbon and play a very important role in climate control. They have a watershed role and are a source of many raw materials that humans depend on. </span>
The
Grassland Biomes:<span> <span>There are
two main types of grassland biomes: the Savanna Grasslands and the Temperate
Grasslands. </span></span>
The Tundra
Biomes:<span> <span>There are
two major tundra biomes—The Artic Tundra and the Alpine Tundra. </span></span>
