Describe two forms of mechanical weathering.
GalinKa [24]
1.Frost Wedging (Freeze-Thaw)

Water expands by 9 percent when it freezes. As it expands, it exerts up to 4.3 million pounds per square foot of pressure. Since water seeks low points, repeated freezing and thawing can lead to deep vertical fissures as cracks are extended downward. Cracks that allow entry of roots lead to similar wedging.


2.Crystal Formation

Crystal formation cracks rock in a similar way. Most water contains dissolved salts. When water in rock fissures evaporate, the salt concentration increases, which leads to crystallization. This occurs in arid regions where the humidity fluctuates widely, so that the salt can be redissolved and carried into new fissures.

Researchers create a recombinant DNA molecule in which the coding sequence for GFP is inserted downstream of the enhancer/promot
Stolb23 [73]

Answer:

-Reporter gene.

Explanation:

A reporter gene can be defined as a gene, which is used as an indicator to check uptake or expression of gene by a cell or organism. It is attached to a regulatory sequence of a different gene of interest in cell culture, bacteria, plants, or animals by the researchers and used to confer its expression in that organism or cell.

Gene for GFP (green fluorescent protein) is an example of reporter gene, due to which cells that express gene of interest emit green color under blue light.

As in given experiment, target gene (gene for rhodopsin) is attached with gene for GFP, it represents an example of reporter gene.

Thus, the correct answer is 'reporter gene.'

jasenka [17]

Answer:

Explanation:

Based on the scenario being described within the question it can be said that  this can be confidently decided if you could show that the ranges of two mice overlap without hybridization occurring. This would allow you to safely predict  whether or not two species of mice have mated with one another or if it two populations are one in the same.
