Answer: Soil moisture and fertility
Cheat grass is likely to decrease the soil moisture of the region, thus rendering the soil infertile and unfit for other plants growth.
Explanation:
Cheatgrass is an exotic weed native to Europe, West Asia and Northern Africa. Cheatgrasses outcompeted native vegetation as a result of large number of livestocks like cattle and sheep into sagebrush region. The livestocks overgrazed on native vegetation, which resulted to a void filled rapidly by Cheatgrass.
Cheatgrass grows on pastures, hills, and ranges. Wildfires promote more Cheatgrass but destroy native plants vegetation. Cheatgrass can survive drought due to deep root system they possess. The deep root system make the plant to grow and flourish with even small amount of water. Its deep root system reduce soil moisture and deplete soil fertility, preventing the growth of other plants. Also, Cheatgrass is self germinating and require les soil to grow. All these attributes that favor Cheatgrass have threatened native plants such as sagebrush plants and woodlands.
There are about 334 different species of marsupials, a large portion of them being in Australia and in South America.
Answer:
mitochondria
Explanation:
aerobic is active and energy is produced in the mitochondria so if the mitochondria was damaged it would affect the active transport
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.
Length of PolyA tail is different in two cells
Explanation:
- Different lengths of Poly A tails are present for different mRNAs so when we compare two peptides translated in two different cells we have different lengths of PolyA tail
- PolyA tail is basically a long chain of nucleotides(adenine nucleotides) which are added to messenger RNA(mRNA) during processing of RNA
- It increases the stability of the molecule
- It protects the mRNA molecule from undergoing degradation in the cytoplasm
- It is involved in binding proteins which further initiates translation;introns are removed from pre mRNA before the final mRNA is exported into cytoplasm
