Answer:
Increases redox potential decreases microbial growth inside food.
Explanation:
The redox potential is considered as one of the most complex indicators of the physical conditions of microbial cultures. The measurement of redox potential could be very useful for the determination of qualitative and quantitative parts of the microbial contamination. During the bacterial growth, the redox potential of the medium decreases. Redox potential is a measure of the tendency of a biological species which can be acquire or lose electrons through ionization. If the redox potential of the medium is increases, there will be lower growth of microbes in the food and vice versa.
Ans.
The mutation that results in a mouse with less light fur as compare to other mice of same population, makes it easier for the mice to blend into their surrounding environment. According to law of natural selection, if a genetic mutation is beneficial for a population, the mutated organism survives to reproduce and that mutation gets transferred on to its offspring.
Thus, the correct answer is 'option). the mouse with the genetic mutation will survive and reproduce, and the trait (for fur) will spread over future generations.'

C) 1 x 10^8
<h3><u>Explanation;</u></h3>
- <em><u>To in scientific notation we need to move the decimal point to the left until the first number is at least one but less than ten. The number of places that you have to move it becomes the exponent or the power of 10.</u></em>
- Therefore, <em><u>to write 100,000,000, in scientific notation, we move the decimal point to the left 8 places until it is after the first digit. </u></em>
- <em><u>The number of places that you move it becomes the exponent (8). </u></em>
- <em><u>The exponent is positive because it is a big number. Zeroes at the end are not part of the answer because they were not significant.</u></em>
Answer:
To understand the physical change and chemical change, one needs to know what is physical properties and what is the chemical properties of a substance.
Physical property is characteristic or trait of a substance that can be observed without converting the substance to a new substance. If there is any type of change in these physical properties like changing the appearance or form of matter and does not make a new substance, takes place it is called physical change.
A chemical change is a change in the matter of a substance that creates one or more new substances. This type of change includes the formation, color, of a precipitate, change in texture, and many other changes.
