b. Write the following in ordinary notation: 3.02 x 10-5
c. Evaluate the following: (3.3 x 10-4mL) = (1.1 x 10-6 mL)
Answer:
a. 0.03054 b. 0.000032 c. sorry I am not perfect
Explanation:
a. In the number 0.03054 , you need to move the decimal point two places to the right to get to 3.054 (which is between 1 and 10). Since you moved the decimal point two places to the right, you must indicate it by saying that you multiplied 3.054 by 10−2 . Think about it: 3.054×10−2=0.03054 . b. Answer: 0.0000302 Step-by-step explanation: When 10 is to the power of a negative number, "move" the decimal dot left. 10⁻⁵ means to "move" the decimal 5 times to the left. 1. Write a bunch of extra 0's for the coefficient. (The coefficient is 3.02). 0000003 . 02 2. Count 5 place values over. 00←0←0←0←0←3 . 02 3. Put the decimal behind the digit. 00 . 0000302 4. Get rid of the 0s that you don't need. You only need one 0 left of the decimal. 0.0000302 <= Final answer c. sorry but I am not perfect at thisA. 0.03054 grams = 3.054 x [tex]10^-^2[/tex] grams
B. 3.02 x [tex]10^-^5[/tex] = 0.0000302
C. 3.3 x [tex]10^-^4[/tex] mL= 300
Powers of 10 are used in scientific notation to express extremely large or extremely small quantities. The formula is "[tex]\rm a * 10^b[/tex],"
where "a" is an integer representing a value between 1 and 10 (inclusive), and "b" is an integer representing a power of 10.
To write 0.03054 grams in scientific notation, we move the decimal point three places to the right to make the number between 1 and 10. this results in:
0.03054 grams = 3.054 x [tex]10^-^2[/tex] grams
To write [tex]3.02 * 10^-^5[/tex] in conventional notation, as indicated by the exponent, we move the decimal point five places to the left. this results in:
3.02 x [tex]10^-^5[/tex] = 0.0000302
To evaluate (3.3 x [tex]10^-^4[/tex] mL) / (1.1 x [tex]10^-^6[/tex] mL), we divide the numbers in the numerator and denominator:
[tex](3.3 * 10^-^4 \rm mL) / (1.1 * 10^-^6 \rm mL) \\= (3.3 / 1.1) * (10^-^4 / 10^-^6) \\= 3 * 10^2[/tex]
Therefore, (3.3 x [tex]10^-^4[/tex] mL) is equal to 300.

Describe why some water uses are called consumptive
Answer:
Consumptive rates are so high because water that is applied to a field is considered lost to the immediate water system. It either gets evaporated, used by the plants, or leaves the field as run-off. In addition, leaks or evaporation cause loss while water is being transported from the source to the field, often over great distances.
During the process of fertilization and pregnancy, which becomes implanted on the uterine wall? (1 point)
gamete
O sperm
Oblastocyst
embryo
Answer:
That is C.) blastocyst. I hope this helps! :)
During pregnancy after fertilization, the embryo gets implanted in the uterine wall. So the correct option is D.
What is an embryo?The embryo is the stage of an animal's early development when it is within an egg or a mother's uterus. When referring to an unborn person, the phrase is used up to the end of the seventh week after conception; starting with the eighth week, the term "fetus" is used.
When an ovum and a sperm unite to form a sexually reproducing organism, the outcome is a zygote, or fertilized egg, which goes through a series of divisions known as cleavages as it travels down the fallopian tube. A hollow ball known as a blastula is created by the cells following many cleavages.
In most animals, the blastula adheres to the uterine lining, causing the placenta to develop and begin supplying the developing fetus with nourishment from the mother. The yolk feeds the embryo in lower animals.
The embryo differentiates into three types of tissue through the process of gastrulation: the ectoderm, which produces the skin and nervous system; the mesoderm, from which connective tissues, the circulatory system, muscles, and bones develop; and the endoderm, which produces the digestive system, lungs, and urinary system.
Therefore the correct option is D.

How is loss of biodiversity connected to extinction of organisms?
Answer:
In an ecosystem, everything is connected. All ecosystems have some form of food chain and symbiosis. This means that animals rely on each other for life. If one animal were to die then others would be negatively affected. Overall, this means that when biodiversity is lost it becomes harder for organisms to survive. For example, pandas rely on bamboo to survive. So, when it gets cut down and destroyed the pandas also suffer. Additionally, in ecosystems, a wide variety of organisms helps other living creates have more forms of survival. This shows how important biodiversity is.

A doctor sees a patient who has kidney failure, lack of motor coordination, and a poorly functioning nervous system. After testing, the doctor finds that these symptoms are all related to a chronic lack of energy in some of the patient's cells. The doctor diagnoses a metabolic disorder known as Leigh's disease.
Based on this evidence, a malfunction in what organelle is most likely responsible for Leigh's disease?
Mitochondria are the energy centers of the eukaryotic cells. In these organelles, ATP (the energy coin of the cell) is produced by the oxidation of pyruvate (Krebs cycle) and oxidative phosphorylation.
Based on this information, malfunction in MITOCHONDRIA is most likely responsible for Leigh's disease.Cellular respiration is series of metabolic reactions by which eukaryotic cells produce energy in the form of ATP from foods and oxygen.Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.Glycolysis occurs in the cytoplasm, whereas the Krebs cycle and oxidative phosphorylation occur in the mitochondria.Learn more in:

What is the difference between the way energy puts limits on life and the way phosphorus does so?
Adenosine triphosphate (ATP) production, the creation of sugar and alcoholic esters, and other energy-transfer processes all need phosphorus.
What is the role of phosphorus in energy?
In many enzymatic processes, where inorganic phosphorus regulates the rate of reaction, phosphorus also serves a regulatory purpose in addition to these other tasks.
This holds true for everything from exploration to the development of young children and is determined not by our muscles and lungs but rather by the amount of energy we can obtain from food.
It has a significant impact on how the body utilizes fats and carbs. The production of protein by the body is also necessary for the development, upkeep, and healing of cells and tissues.
Therefore, the way energy puts limits on life and the way phosphorus is different.

What do you think interphase is? What might the cell be doing in this phase? Think about the prefix "inter". Write your best definition - it's ok if you're not sure, just try your best!
Answer:
Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions. Interphase was formerly called the resting phase.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division
Interphase is the part of time which mostly the cell utilises for its functionality.

What is the definition of period?
1) cycles per second
2) vibrations per hour
3) seconds per cycle
4) Number of vibrations
Period is defined as cycles per second. Therefore option (A) is correct.
What are the characteristics of period?A period T is the time required for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the period of the wave decreases.
The unit for time period is 'seconds'. Frequency and time period are in a reciprocal relationship that can be expressed mathematically as: T = 1/f or as: f = 1/T. Orbital period is the time for something to go round (orbit) something else.
Frequency and Period are in reciprocal relationships and can be expressed mathematically as: Period equals the Total time divided by the Number of cycles.

O4 water molecules are lost from each bond broken
O 4 Water molecules are used for every
O 1 water molecule is lost (OH + H) for every bond formed
Glucose molecules bond together in a process known as dehydration synthesis, and in this process, 1 water molecule is lost (OH + H) for every bond formed. The last option is correcting the glucose dehydration reaction.
What is glucose dehydration?The macromolecules, such as the polysaccharides and proteins, are formed by the dehydration reaction, and in this reaction, the water is lost to make the polymer. The single glucose molecules unite with each other and release a single unit of water to form the polymers, and in this way the polymers such as glycogen, starch, and cellulose are formed.
In the case of proteins, each amino acid dehydrates and releases one molecule of water, forming the polypeptide chain. As a result of the dehydration process, the monomers combine to form the polymer, which can be structural or functional.
Hence, for every bond formed, one water molecule (OH+H) is lost. The last option is correct regarding the glucose dehydration reaction.
