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
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.

Explanation:
Key deer are found only on certain islands in the Florida Keys. Populations are typically small enough that genetic drift has caused significant deviation among populations on different islands. For example, the population on No Name Key has allele frequencies of A1 = 0.43 and A2 = 0.57 while the population on Big Pine Key has allele frequencies of A1 =0.21 and A2 = 0.79. Construction of roads has recently increased migration rates between these populations to approximately 0.08 per generation. What will the frequency of A1 be on Big Pine Key after a single generation of migration from No Name Key?
Answer:
The frequency of A1 be on Big Pine Key after a single generation of migration from No Name Keyp is 0.2276
Explanation:
Whenever it occurs migration between two populations, there is genetic flux going on. Genetic flux might be considered as an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.
Genetic flux acts homogenizing the allelic frequencies between the two populations, and it might introduce variability.
By knowing the allelic frequencies in both populations at a certain time and the migration rate, we can calculate the allelic frequencies of populations in the next generation. This is:
pA₂=pA₁(1-m)+pB₁ m
pB₂=pB₁(1-m)+pA₁ m
Being
A one population and B the other population pA₁ and pB₁ the frequencies of the p allele before migration, pA₂and pB₂ the frequencies of the p allele after migration, m the migration rateIn the exposed example, we know that:
No Name Key population allelic frequency: A1 = 0.43 and A2 = 0.57Big Pine Key population allelic frequency: A1 =0.21 and A2 = 0.79Migration rate m=0.08Let´s say that p represents A1 allele, and q represents A2 allele.
The frequency of A1 allele (p) be on Big Pine Key (Population B) after a single generation of migration from No Name Key (Population A)
pB₂=pB₁(1-m)+pA₁ m
pB₂=0.21 x (1 - 0.08) + 0.43 x 0.08
pB₂= 0.2276
The allelic frequency in a population after one generation is the allelic frequency of individuals of that population that did not migrate (21 x (1 - 0.08) plus the allelic frequency of the new individuals that came from the other population (0.43 x 0.08).
You can corroborate your result by calculating the q allele frequency in the next generation and summing both of them up. The result should be one.
qB₂= qB₁(1-m)+qA₁ m
qB₂= 0.79 x (1 - 0.08) + 0.57 x 0.08
qB₂= 0.7724
p + q = 1
0.2276 + 0.7724 = 1
Domesticated dogs are descended from wolves, and modern dog breeds are the result of artificial selection. Imagine that you were given a population of wolves and asked to
ultimately produce Chihuahuas (if you don't know this breed of dog, please Google it).
1. If you had a bunch of wolves and wanted a Chihuahua, how you create one? List just one thing you would do.
2. Explain how your strategy would work.
Hint: Think about what you learned about natural selection.
Answer:
organisms acclimate over time is by adapting to their habitats and their ecosystem. If i were to make a population of wolves into a chihuahua i would make sure that the habitat is smaller and also the amount of resources available should be less than what they are used to. This should cause them to become smaller to help preserve energy.Once they breed and a favorable genetic is present, that wolf is used to breed with another wolf that has a genetic mutation that would make it smaller and more domesticated. By taking genetic mutations that are a result from these changes you can get a wolf to be more domesticated and become smaller. like a chihuahua
The functions of the oral cavity include all of the following, except:_________a. mechanical processing of food. b. digestion of carbohydrates. c. analysis of material before swallowing. d. lubrication. e. absorption of monosaccharides.
Answer:
e. absorption of monosaccharides
Explanation:
The oral cavity is the first part of the digestive system where food is received, crushed, mixed with digestive enzymes secreted at that level, and also where the food is turned into the form of bolus before it is being channeled down through the pharynx into the alimentary canal for further digestion.
The oral cavity is also a site for respiration and speech production.
It is made up of the teeth, hard and soft palate, tongue and other vital parts that play different roles in food digestion.
The function of the oral cavity does not include absorption monosaccharides.

Darwin's ideas espoused in both Origin of Species and The Descent of Man were incompatible with the prevalent scientific racism of the age (like that of Robert Knox, for example) because of Darwin's emphasis on _______.
Answer:
The correct answer is "change".
Explanation:
The missing options of this question are:
A. natural selection.
B. immutability.
C. survival of the fittest.
D. change.
The correct answer is option D. "change".
The scientific racism that was prevalent during Charles Darwin books publications was related to the concept of "pure races", and the association of the inheritance of the "superior attributes" related to these races. Darwin's ideas were incompatible to this scientific racism, since Charle Darwin theories support the idea of a constant change among all people attributes, produced by genetics behavior and exposure to environmental factors.
What is a substrate? a molecule that acts as a catalyst a place where the reaction occurs a place on the product where the enzyme fits a reactant that is catalyzed by an enzyme
Answer:
a reactant that is catalyzed by an enzyme
Explanation:
Reactants are often referrred to as substrates as those are what enzymes mostly act upon to create products or some desired consequence
Option (d). a reactant that is catalyzed by an enzyme is called the substrate.
SubstrateA substrate exists as a molecule on which an enzyme acts. Enzymes catalyze chemical reactions that concern substrate, where the substrate binds to the enzyme's active site, and an enzyme-substrate complex is created. By action of the enzyme, the substrate exists transformed into a product, released from the active site, and free to obtain another substrate.
Enzyme catalysis exists as the increase in the rate of a process by a biological molecule, an "enzyme". Most enzymes exist in proteins, and most such processes are chemical reactions. Within the enzyme, naturally, catalysis happens at a localized site, called the active site.
The reactant in an enzyme-catalyzed reaction is named a substrate.
Because enzymes can expand reaction rates by enormous factors (up to 1017 times the uncatalyzed rate) and tend to be very precise, typically producing only a single product in quantitative yield, they exist the focus of active research.
Hence, Option (d). a reactant that is catalyzed by an enzyme is called the substrate.

The amino acid methionine is specified by the codon 5'-AUG, and a methionine tRNA can have the anticodon sequence 5'-CAU. Which of the following is the base sequence of the template strand of the part of the tRNA gene corresponding to the anticodon?
5'-GTA
5'-CAU
5'-CAT
5'-UAC
5'-AUG
5'-GUA
5'-TAC
5'-ATG
Answer:
5' CAT
Explanation:
The template strand is also known as the coding strand which runs in the 3' to 5' direction as the mRNA is synthesized in the 5' to 3' direction.
In this case the 5' AUG on the mRNA is complementary to the 5'CAU on the methionine tRNA.
This 5' CAU corresponds to the 5' CAT on the template strand of the DNA sequence. This is in reverse to the 5' AUG due to the direction of mRNA synthesis.

The protein thorain is encoded by the gene thrL, and thorain is a negative regulator of the thrMN operon. Assume there is no other regulation taking place. Predict the phenotype of a thrL- mutant that encodes a nonfunctional thrL protein.
a. The thrM and thrN genes would be transcribed at higher levels compared to non-mutant.
b. The thrM and thrN genes would be transcribed all lower levels compared to non-mutant.
c. The thrM and thrN genes would not be transcribed
Answer:
The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.
Explanation:
Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.
With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.

Bats hunt using echolocation, in which they send and receive high frequency sounds to locate prey. When bats hear the sounds of others,
they typically begin hunting in the same area. As the number of bats hunting in the area increases, individuals become more successful at
locating and capturing prey.
Some populations of bats live in areas with high levels of noise pollution, such as near heavily trafficked bridges. How might the hunting
behavior of bats be affected by such an environment?
A
Bats would be less likely to hunt in groups, so an individual's success in catching prey would decrease.
B.
C.
Bats would be unable to use echolocation, which would prevent them from finding any prey.
Bats would be more likely to hunt in groups, so an individual's success in catching prey would increase.
Bats would be better able to use echolocation, which would improve their ability to find prey.
D.
Answer:
A
Simply the noise from heavy traffic will cause the destructive interference which reduces the echolocation,blocking the echoes and therefore prevent prey location for bats.
Generally this reduces the Bats' population, as some could not rely on the echo to locate the prey, leading to starving and death. Thus each bat needs to rely on the individual echolocation from the prey to survive as new hunting adaptation.Since the echolocations has been blocked
Answer:
Bats would be unable to use echolocation, which would prevent them from finding any prey.
Explanation:
Besides the HCT, what other component of blood could be measured to give a better understanding of oxygen-carrying capacity? Explain your answer.
Answer:
The haemoglobin levels or counts can be used.
Explanation:
The oxygen carrying pigment of the blood is the heamoglobin (Hb).it is a protein molecule with for heam groups,Each of the latter can bind with 4 molecules of oxygen in a cooperate bonding.The more oxygen molecules binding by Hb,the more oxygen is carry in RBC.
Therefore if the number of Hb counts is reduced in an individual the volume of oxygen in the RBC of the subject should reduced,Therefore, this should be a good indicator of the lower oxygen capacity of the blood of the individual.
Basically in a physiological female the Hb count/100ml of blood is 12-16g/ml,like wise 13-18g/100mI in a physiological man.
Therefore fluctuations in the levels of these values below the set points is an indicator of distortion in the oxygen carrying capacity of the blood.
The amount of the blood in volume that contains RBC is called Hematocrit. Therefore for accuracy the HCT together with the Hb counts are good indicators of oxygen capacity of the blood.
Hematocrit refers to the volume percentage of the red blood cells in the blood. Oxygen-carrying capacity can be measured by several techniques.
The co-oximetry and Arterial Blood Gas can be used to determine the oxygen-carrying capacity.
The techniques can be explained as:
Co-oximetry is a type of blood test used to measure the oxygen-carrying capacity of the hemoglobin in the blood. The test uses the light of different wavelengths that can pass through the blood to determine oxygen capacity. Arterial blood gas or ABG test is a type of blood test used to measure the pH and oxygen-carrying capacity of the blood present in the artery. It is used to determine the efficiency of the lungs to exchange the gas oxygen and carbon dioxide from the blood.
Thus, the co-oximetry and ABG test can be used to determine oxygen levels in the blood.
