Which are considered two of the special properties that are used to identify certain minerals?
O hardness and luster
O magnetism and fluorescence
O streak and color
O cleavage and fracture
Answers
Answer:
The answer is
2. magnetism and fluorescence
Explanation:
The other properties mentioned are common properties that are used to identify all minerals. As you can see, hardness, color and fracture are common properties that cut across all minerals. Magnetism and fluorescence however, are not very common and are found in only a few special minerals. That is why they are considered special properties.
Hope this helps!
magnetism and fluorescence are considered two of the special properties that are used to identify certain minerals. Thus option B is correct.
what are the properties to identify an object ?
Minerals are the chemical compound which has a well -defined composition and a specific crystal structure and occurs naturally in the pure form.
If a compound occurs naturally in different crystal form then it is referred as a different mineral. The chemical composition of a mineral varies depending on the presence of small impurities which are present in small quantities.
Some minerals can have variable proportions of two or more chemical elements which occupy equivalent position in the crystal structure; it has variable composition which is split into separate species.
minerals include color, streak, luster, specific gravity and cleavage as their physical properties, shows no magnetism. Basically magnetism is the physical property of the minerals, magnetism does not have these elements. thus, have no magnetism called diamagnetic. Examples of diamagnetic are quartz, apatite and calcite.

Identify the statements that accurately describe how hydrogen ion concentration relates to energy production in oxidative phosphorylation. The pH in the intermembrane space is higher than the pH in the mitochondrial matrix. Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain. Hydrogen ions are actively transported out of the mitochondrial matrix. Hydrogen ion concentration is higher in the intermembrane space than in the mitochondrial matrix. Energy is generated as a result of the difference in hydrogen ion concentration between the mitochondrial matrix and the cytoplasm.

This requires you to use all the things we have learned in this chapter. 1.55 grams of Carbon disulfide
is added to 2.83 grams of Oxygen to form Carbon dioxide and Sulfur dioxide. If the reaction yields
1.1 grams of the Sulfur dioxide what was the percent yield?
27%
14%
Ο Ο Ο Ο Ο
74%
42%
O 63%
Answers
Answer: The percent yield is, 42%
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of carbon disulphide}=\frac{1.55g}{76g/mol}=0.020moles[/tex]
[tex]\text{Moles of oxygen}=\frac{2.83g}{32g/mol}=0.088moles[/tex]
The balanced chemical reaction is:
[tex]CS_2+3O_2(g)\rightarrow CO_2+2SO_2[/tex]
According to stoichiometry :
1 moles of [tex]CS_2[/tex] require = 3 moles of [tex]O_2[/tex]
Thus 0.020 moles of [tex]CS_2[/tex] will require=[tex]\frac{3}{1}\times 0.020=0.060moles[/tex] of [tex]O_2[/tex]
Thus [tex]CS_2[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess reagent.
As 1 mole of [tex]CS_2[/tex] give = 2 moles of [tex]SO_2[/tex]
Thus 0.020 moles of [tex]CS_2[/tex] give =[tex]\frac{2}{1}\times 0.020=0.040moles[/tex] of [tex]SO_2[/tex]
Theoretical mass of [tex]SO_2=moles\times {\text {Molar mass}}=0.040moles\times 64g/mol=2.56g[/tex]
Actual mass of [tex]SO_2[/tex] = 1.1 g
Now we have to calculate the percent yield
[tex]\%\text{ yield}=\frac{\text{Actual yield }}{\text{Theoretical yield}}\times 100=\frac{1.1g}{2.56g}\times 100=42\%[/tex]
Therefore, the percent yield is, 42%

Answers
Answer:
The main cause of earthquake is the motion of tectonic plates which occurs due to friction.
Explanation:
The tectonic plates moves slowly inside the earth crust but the edges of these plates stuck with each other due to friction that occurs during their contact. When these two plates detached from each other, the force of friction converts in a form of wave energy which can be observed in the form of earthquake. Divergent, convergent, and transform are the three types of plate boundaries which are responsible for earthquake.

A) Incomplete dominance because the intermediate form of the trait is chosen
B) Co-dominance because the intermediate form of the trait is chosen C) Incomplete dominance because the offspring display alleles for both hair colors
D) Co-dominance because the offspring display alleles for both hair colors
Answers
Answer:
A
Explanation
the red haired trait is dominant over the white haired trait. and the results are all red haired offspring. therefore its incomplete dominance
The correct option is D) Co-dominance because the offspring display alleles for both hair colors.
What is Co-dominance?Co-dominance refers to a phenomena, in which both alleles are simultaneously expressed in the heterozygote.
Incomplete dominance is closely related to Co-dominance in which phenotype of the progeny is intermediate of the parent phenotype.
Here, the red haired trait is dominant over the white haired trait and still both alleles are simultaneously expressed in the heterozygote of the offspring with red and white hair traits, thus, the Co-dominance best describes this inheritance pattern.

A farmer plants Bt cotton that is genetically modified to produce its own insecticide. Of the cotton bollworms feeding on these Bt plants, only 5% survive unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide. When the farmer first plants Bt cotton, the frequency of the R allele in the cotton bollworm population is 0.01. What will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton [answer]
Answers
Answer:
the frequency of the resistant allele after one generation is 0.989
Explanation:
Given that :
A farmer plants Bt cotton that is genetically modified to produce its own insecticide.
Of the cotton bollworms feeding on these Bt plants, only 5% survive
i.e the survival rate s = 5% =0.05
unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide
Frequency of R allele = 0.01
In order to determine what will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton; we need to first determine the frequency of the recessive allele r.
According to Hardy-Weinberg Equilibrium ;
p+q = 1
Let p = R and q = r
R + r = 1
0.01 + r = 1
r = 1 - 0.01
r = 0.99
Now; the frequency of the resistance allele after one generation can be calculated as :
[tex]q' = \dfrac{q(1-sq)}{1-(sq^2)}[/tex]
where ;
q' = R
q = r
[tex]q' = \dfrac{0.99(1-(0.05 \times 0.99))}{1-(0.05 \times 0.99^2)}[/tex]
[tex]q' = \dfrac{0.99(0.9505)}{1-(0.049005)}[/tex]
[tex]q' = \dfrac{0.940995}{0.950995}[/tex]
q' = 0.989
Thus; the frequency of the resistant allele after one generation is 0.989

This element is a gas that is found in both nucleic acids and in amino acids, important building blocks of life. What is it? A. Nitrogen B. Sulfur C. Oxygen D. Carbon My answer is: A) Nitrogen
Answers
Answer:
Yes, your answer, nitrogen, is correct (the most appropriate option). However, oxygen is also a correct option.
Explanation:
Nitrogen exists on its own as a diatomic gas. However, it exists as organic nitrogen in nucleic acids such as DNA and RNA (as part of their nitrogenous bases) and in the amino (--[tex]NH_{2}[/tex]) group of amino acids.
Do note that a case can also be made for oxygen as a right option: like nitrogen, it exists as a diatomic gas and can be found in both nucleic acids and in the carboxylic group of amino acids.
Sulfur is not an appropriate option as nitrogenous bases (and nucleic acids) to the best of my knowledge do not contain sulphur although some amino acids like cysteine do.
Carbon is not also an appropriate option because elemental carbon does not exist in gaseous form even though it can be found in both nucleic acids and amino acids.

the diagram below shows a sarcomere if a disorder makes it impossible for atp to bind to the myosin head what would happen to the sarcomere?
Answers
Answer:
B. The myosin and actin would not separate, and the sarcomere would remain contracted
Explanation:
ATP (adenosine triphosphate) acts both in the binding of myosin to actin, which occurs during muscle contraction, and also in its separation, which occurs during muscle relaxation.
When ATP is lacking, myosin remains attached to actin, causing muscle stiffness. This is what happens after death, producing a state of cadaverous rigidity (also called "rigor mortis").
An intense and uninterrupted stimulation causes the muscle to reach the maximum degree of contraction. Then, the muscle remains in contraction, this state is called tetany.
A very prolonged state of tetany causes muscle fatigue, in which, due to ATP deficiency, can cause a loss of muscle contraction capacity, after its relaxation.
