Aliyah found a tarnished silver dollar and recalled that tarnish results when metals react with oxygen or sulfur compounds in the air. She polished the silver dollar to remove the tarnish until it was shiny again. She also polished a copper bracelet and a gold ring. What physical property of these metals makes them shiny?
Answer:
LUSTER
Explanation:
The physical property of the metals that make them shiny is called Luster. Therefore, Aliyah was able to polish the metals like silver, copper, and gold.
What is luster?Luster is one of the important physical properties of the metals, which refers to the way light is reflected from the surface of the metal. In the context of metal, luster refers to the shininess or brightness of the metal surface.
The luster of a metal ranges from dull to very shiny and can influence the perceived value of the metal as well as its suitability for various applications.
The luster of a metal can be affected by factors such as surface roughness, impurities, and exposure to environmental conditions such as corrosion and oxidation.
The treatment of a metal surface, such as polishing and plating, can also impact the luster of a metal.

When pouring food coloring into warm water and cold water, we can see that the
molecules in warm water move faster and spread the food coloring more quickly.
(Conduction Lab Experiment)
true
false
Answer:
true!!
Explanation:
the faster molecules move, the warmer the object is. think of how much energy you feel when you touch hot water and you whip your hand back, thats similar to how the molecules are movin, all that heat is energy built up in them and theyre moving around all crazy haha. Then think of putting ice in the freezer, all the molecules are kinda frozen in place, all squished together, because they dont have enough energy to move around. so, when the hot molecules with all that energy are moving around, the food coloring is able to get all over in the water. Kind of like if youre on a road trip the faster you drive the faster you'll get places. if you drive super slow, then it'll take forever to get there. so true, when food coloring is dropped into faster hotter molecules, it will spread faster. :)
Water is a liquid substance that can act as a solvent for solute components.
It is true that when pouring food coloring into warm water and cold water, we can see that the molecules in warm water move faster and spread the food coloring more quickly.
The energy in the water molecules of warm/hot water is very high due to the effect of heat so when food coloring is poured, the water molecules move at a fast rate causing the food coloring to spread at a fast rate across the water molecules.The energy in the water molecules of cold water is very low so when food coloring is poured, it spreads at a slower rate.Therefore, it is true that when pouring food coloring into warm water and cold water, we can see that the molecules in warm water move faster and spread the food coloring more quickly.

List the following structures from largest to smallest: proton pump, nuclear pore, cyt c ribosome,
nucleus.
Answer:
Nucleus
Nuclear pore
Proton pump
Cyt C Ribosome
Explanation:
The nucleus of the cell is the largest of all of these structures, all of the others are located inside the nucleus of the cell or interact with it, the nuclear pore is a pore in the nucleus that allows the transport of proteins through the membrane, the proton pump passes through the nuclear pore, and a Ribosome is a protein that transports nutrients, so that would be the smallest.
The order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.
The nucleus is the organelle that contains the genetic material in a eukaryotic cell, whereas ribosomes are protein factories.The nuclear pore is a structure that allows the passage of certain molecules between the cytoplasm and the nucleus.The proton pump is an integral protein-membrane, whereas Cyt C is a mitochondrial protein.In conclusion, the order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.

How does the movement of water, carbon, and nitrogen in ecosystems differ from the movement of energy?
Please help me this is due today, thank you if you do^^
Answer:
While water, carbon, and nitrogen cycle through the ecosystem, energy flows through an ecosystem.
Explanation:
There is a limited amount of water, carbon, and nitrogen in an ecosystem, and therefore, it cycles and passes through an ecosystem multiple times. In the case of energy, however, it is different. Energy goes into a system, flows from organism to organism, and then leaves the system. For example, with water, that water will rain, gather in a river or body of water, and evaporate, doing the cycle over and over again. Energy from the sun however, gets collected by producers, then flows to the organism that eats the plant, then flows to the organism that eats that organism, and so on. The energy does not return to the sun, it just leaves the system (like for example when an organism dies).
If a red-eye female fly is crossed with a red-eye male fly, could they produce offspring with white eyes? Briefly explain your answer. Your answer must include a Punnett square that proves your answer.
If the red-eye parents are homozygous, no. But if the red-eye parents are heterozygous, yes.
Monohybrid crossingWe are assuming that the red-eye trait is dominant over the white-eye trait. If two red-eye parents are crossed with one another, whether they could produce white-eye offspring would depend on the zygosity level of the parents.
Assuming that red-eye is R and white-eye is r. If the two parents are homozygous red-eyed, their genotypes would be RR. Crossing the two:
RR x RR
RR RR RR RR
All the offsprings would be RR and there is a zero chance of producing a white-eye offspring.
Now, assuming that the two parents are heterozygous:
Rr x Rr
RR Rr Rr rr
Both RR and Rr are red-eyed while rr is white-eyed. The Punnet's square for the cross can be found in the attached image.
In other words, it will only be possible for the two red-eye parents to produce white-eye offspring if they are both heterozygous. Any other genotype will give a zero chance of white-eye offspring.

Which statement best describes the initial process of N-linked glycosylation in the endoplasmic reticulum
Answer:
The oligosaccharide is assembled on the lipid carrier at the membrane of the ER
Explanation:
N-linked glycosylation consists of the attachment of an oligosaccharide (glycan) to a nitrogen atom of the asparagine (Asn) residue in the protein. N-linked glycosylation is a key posttranslational modification (PTM) capable of controlling protein structure and function, this pathway takes place in the plasma membrane in archaea organisms and in the membranes of the endoplasmic reticulum (ER) in eukaryotic organisms. In eukaryotic cells, the N-linked glycosylation conserved pathway consists of two steps. In the first place, the oligosaccharides are assembled on a lipid carrier called dolichyl pyrophosphate localized in the endoplasmic reticulum (ER). The dolichyl-phosphatase is a hydrolase enzyme that acts on phosphoric monoester bonds. Second, the oligosaccharides are modified by specific glycosyltransferases that transfer these molecules to selected Asparagine (Asn) acceptor residues of polypeptide chains that have entered the lumen of the ER. These N-glycans are firstly assembled as a dolichol-linked precursor oligosaccharide at the cytoplasmic face of the ER.
Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?
Answer:
In the clarification portion below, the definition of the topic is mentioned.
Explanation:
This shows that the distinctions between people living in a culture or geographical region are often based on ethnicity including ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair color, body potential for heat resistance, and menu variety. In something like a specific race or ethnic group, these social traits bring them alongside, and the young government associated with a particular race is often obligated to answer the custom practiced by individuals related to such a particular demographic.

Many male birds will expend a great deal of energy building nests. Females will mate with the males who build the best nests. This is best described as an example of ____.
a. natural selection
b. sexual selection
c. runaway selection
d. an invasive species
e. disruptive selection
Answer:
The correct answer is option B. sexual selection.
Explanation:
Sexual selection is a special type of natural selection proposed by Charles Darwin. According to this type of natural selection in which a particular sex organism chooses the opposite sex member of the species to mate with on the basis of the preferable traits and compete with the other members of the opposite sex.
Here female birds choose those male birds who build the best nests, it is an example of natural selection.
Distinguish between the different ways volcanoes cause damage.
Answer:
Hi! Your answer is:
The volcanic plume of an eruption is the pyroclastic flow which sends large amounts of ash and rock into the air and along the ground surrounding the volcano. When this ash and rock mixes with water it forms lahars which flows down the slopes of volcanoes like a landslide, clearing everything in its path. The rocks thrown into the air by the pyroclastic flow, tephra, fall to the ground causing damage where they strike. Toxic gases released through fumaroles can result in acid rain, air pollution and can deplete atmospheric ozone. And of course molten rock emitted from volcanoes as lava flows in streams down volcanoes destroying vegetation and property wherever it touches.
Explanation:
Volcanoes emit deadly gases, ash, lava, and rock. Volcanic eruptions kill. Floods, mudslides, power outages, drinking water poisoning, and wildfires can follow volcanic eruptions, posing health risks.
What are volcanoes?The pyroclastic flow that results after an eruption of a volcano is known as the volcanic plume. This flow transports significant quantities of ash and rock into the air and along the ground in the area surrounding the volcano. When this ash and rock combines with water, it generates lahars, which are similar to landslides and rush down the slopes of volcanoes like a river, sweeping away everything in their path.
When they hit the ground, the rocks that were thrown into the air by the pyroclastic flow, known as tephra, cause damage to the area where they land. Toxic chemicals that are emitted by fumaroles have the potential to cause acid rain, contribute to air pollution, and reduce the amount of ozone in the atmosphere.

The zika virus was first identified in Uganda in 1947. The virus is transmitted from person to person by a bite from a mosquito. It is commonly carried by the Aedes mosquito which is prevalent throughout Central Africa. The virus has more recently spread to the Americas (South, Central, and now North) and is expected to spread to Europe. There is a concern that the virus may reach epidemic proportions. Zika virus is related to yellow and dengue fever. Common symptoms are low grade fever and a distinctive skin rash and other symptoms include vomiting, headache, and muscle and/or joint pain. Pregnant women should avoid traveling to areas known to have zika virus present because the virus is known to cause microcephaly and developmental difficulties related to the central nervous system. Based on the paragraph above, class discussions, and other VALID (be careful with your selection of e-materials! CDC – Center for Disease Control is a good place to start) sources of information please answer the following questions.
1. State a reason why the virus has spread to the Americas and likely to spread to Europe.
2. Define the term microcephaly.
3. What bones of the fetal skull would be affected by zika? Specifically, what area of the CNS is not fully developed in microcephalic individuals.
Answer:
1. It is a highly contagious disease transmitted from person to person and thereby it is expected that infected persons carried the virus to America
2. Microcephaly is a serious birth defect where a baby’s head is much smaller than expected.
3. Occipital bone. CNS malformations: ventriculomegaly, parenchymal and periventricular calcifications and cortical migration anomalies
Explanation:
The Zika virus (Flaviviridae) causes a contagious disease and it is transmitted by Aedes mosquitoes, which are also the main vectors of the dengue virus. Microcephaly is a condition where the baby’s brain has not developed properly during pregnancy, and it has been shown that this birth defect is associated with the Zika virus. During 2015 in Brazil, the incidence of infants with microcephaly born from mothers that contracted this disease during pregnancy was higher, thereby suggesting an association between both conditions. Baby health problems associated with Zika infection include microcephaly (skull partially collapsed), joints with limited motion, etc.
How do you get 0 blood type?
Answer:
You cannot change your blood type. You are born with what you are biologically given and it is permanent.
Answer:
What happened was that dad and mom each passed both an O and an Rh negative to the baby. The end result is an O negative child. Each of their kids has around a 1 in 8 chance of having O negative blood. This is possible because both O and Rh- are something called recessive traits.
