Luster term refers to the way light interacts with the surface of a rock or mineral
<h3>Explanation:
</h3>
Luster is a term used to describe the way that light interacts with the surface of a mineral, rock, or solid or surface such as glass or a manmade crystal. Luster is one of many physical properties (others are hardness, streak, cleavage, crystal shape, color, etc.)
Where large deposits of a desired mineral are found, in an area will experience a short-term economic boom and The area will experience a downturn once all of the available resources are mined . It is a period of significant output within a population. The period is marked by productivity increases, sales increases, wage increases and rising demand. An economic boom may be accompanied by a period of inflation.
Which statements accurately compare the environmental impact of surface mining to the environmental impact of underground mining? The risk of sinkholes is higher in surface mining than in underground mining. and There is a higher risk of release of dangerous gases in surface mining than in underground mining
The use of which material can substitute for copper and reduce copper mine production? aluminum because prices for copper and aluminium were relatively similar and copper and aluminium metal had a dominant area of application

Adaption, during adaptation certain traits in a species can be passed on. When a change in environment is presented certain traits begin to develop when the species reproduce due to mutations in the DNA. The more the new trait due to mutation, is shown during reproduction the more it passes on from parent to offspring. EX.1: Polar bears, they originated from a brown bear but as the land began to get cold and snowy, certain mutations occured causing one offspring to be born with white fur. Once that bear began to reproduce the trait became more common, and due to the adaptation the polar bear could blend in to its surroundings more making it easier to hunt prey. Brown bears were not able to keep producing and living due to slowly dying off from starvation causing the trait of white fur to be more common. The species begin to mate with other species with similar traits to keep on surviving. I hope this answered something if not please message me.
Answer:
C. Extinction
Explanation:
Classical conditioning is also known as respondent conditioning and during training, strengthening of a conditioned response is key.
Also, according to Thorndike, learning is strengthened and more likely to occur each time a response is followed by a satisfying state of affairs.
Therefore, if the unconditioned stimulus no longer follows the conditioned stimulus, extinction would occur.
Answer:
The hamsters were all brown because one side gave all dominant genes.
Explanation:
In the question, it tells you that one group of hamsters all had the genotypes BB. The other group had the genotype bb. In biology, capital letters represent dominant traits and lowercase represent recessive traits. Using this knowledge, we now know that one hamster has all dominant genes, while the other had all recessive genes. In this example, we will only need to use one law of inheritance: the law of dominance. In the law of dominance, if an individual inherits two different alleles (B & b) and only one phenotype is visible (the brown of B), then that allele is dominant. That explains why the hamsters are all brown! Each hamster has one dominant allele that came from the hamster that had BB. Now, you might wonder where the Punnett Square ties into this. A Punnett square is used to track the alleles of organisms. If you draw a Punnett square, you'll be able to see that each box has Bb inside of it. This means that each hamster offspring carries one dominant and one recessive gene inside of it. While they all have a b, the dominant B gene is also there, so the hamsters are all brown. I'm sorry this is so wordy, but I hope this helps!
