Answer:
A cell will shrink when the concentration of electrolytes is greater inside the cell than outside the cell.
Explanation:
<em>When the concentration of electrolyte is greater inside the cell than its outside, water molecules move from the outside electrolyte into the cell leading to its expansion and turgidity. If the water movement continues, the cell may burst and release its contents in a process known as lysis.</em>
Hence, that a cell will shrink when the concentration of electrolytes is greater inside the cell than outside of the cell is false.
Answer:
In 1630 at the beginning of European settlement, about 425,000,000 hectares of the US were forested. By 2017, the area of forested land has declined to 300,000,000 hectares. What is the percent decrease of forested land between 1630 and 2017?
1630= 425000000
2017= 300000000
decrease= 125,000,000
percentage decrease= 125000000/425000000 x 100
percentage decrease= 29.41%
Explanation:
Answer:
The structures that helps the plant ensure that it’s pollen is moved to other plants of the same species and that sexual reproduction will happen is the bright colored petals and sterility of carpel.
Bright colors of petals attracts the insects like bees, which helps the plant to transfer its pollen to other flower of the same species. In some plants, pollen matures earlier than its own stigma so the pollen transfer to other flowers.
Answer is A. A Hox gene
Hox genes are a series of genes that controls the differentiation of cells and tissues in an embryo by turn on and off other genes. If Hox genes express incorrectly, a major changes in the morphology of the individual can be seen.
Let’s understand this with an example: The Ultrabithorax, a Hox gene determines the Third thoracic segment in <em>Drosophila melanogaster</em>. Third thoracic segment displays a pair of legs and a pair of reduced wings used for balancing. In the mutant<em> Drosophila</em> the functional Ultrabithorax protein is absent. Due to this mutation, the third thoracic segment now expresses the same structures found on the second thoracic segment, which contains a pair of legs and a pair of wings which are fully developed .

This is because nickel acts as a cation, therefore you would be attracting anions, in this case it would be on the proteins that would be binding to the column. Once they bind to the matrix a was buffer of high salts can elute the proteins.</span>
