Which mineral is commonly mined as a source of the element lead (Pb)?
a. galena
b. quartz
C. magnetite
d. gypsum

Answers

Answer 1

Answer:

Answer Is Choice A Galena

Explanation:

Answer 2

Galena mineral is commonly mined as a source of the element lead (Pb). The correct option is A.

Galena contains silver in many cases and is thus frequently mined as a source of both silver and lead. Antimony, copper, and zinc are three commercially important minerals that are frequently found in close proximity to Galena.

What is galena mined for?

Galena is a vital mineral because it is used to produce the majority of the world's lead. It is also a significant silver ore. Galena has few uses aside from being an ore, but this does not diminish its significance in society.

Galena is the primary ore of lead and has been used since ancient times because lead can be smelted from galena in a regular wood fire. Galena is frequently found in hydrothermal veins with sphalerite, marcasite, chalcopyrite, cerussite, anglesite, dolomite, calcite, quartz, barite, and fluorite.

Thus, the ideal selection is option A.

Explain what may happen when two waves traveling from oppiste directions meet?
Hint; Think abbout how the crests and troughs of these waves might be effected.

Answers

Answer:

Explanation:

They undergo a wave interference which can either be constructive or destructive interference. Constructive interference happens when the crests of one wave overlap the crests of the other wave (the waves are said to be in phase). This causes an increase in wave amplitude.

Destructive interference occurs when the crests of one wave overlap the troughs of the other wave (waves are said to be out of phase). This causes a decrease in wave amplitude.

Which of these is NOT true about recessive alleles?
A:A. Recessive alleles are expressed when there is one copy present.
B:B. Recessive alleles can be carried from one generation to the next.
C:C. Recessive alleles reappear by being expressed in a later generation.
D:D. Recessive alleles are masked by dominant alleles.

Answers

Answer: A:A. Recessive alleles are expressed when there is one copy present.

Explanation:

Individuals receive two copies of each gene called as allele. A recessive allele is the one which is not able to express when another allele of the same gene is of dominant type. Thus the phenotypic expression will be of the dominant type of gene. The recessive allele is only expressed when the other complementary allele is also of recessive type and thus the expression of recessive allele occurs in the phenotype. So, both alleles should be recessive to express a recessive phenotypic trait.

Based on their design, Blake is designing a study for her campus. The initial part of the study will be a month-long measuring of elevator and stair use in four buildings on the campus. This will be followed by the treatment, which is the simultaneous posting of signs at each of the four locations. Elevator and stair use will then be measured for another month. Which type of design is this?
A. stable baseline
B. multiple baseline
C. matched groups
D. interrupted time-series

Answers

Answer:

stable-baseline

Explanation:

In simple words, Design from a solid foundation. A small model wherein an investigator tracks behavior for a prolonged baseline time before starting a medication or other interference; if behavior is consistent over the retrospective, the investigator may be more confident in the operations efficacy.

Thus, from the above explanation we can conclude that the correct answer is stable baseline.

That is because the Fed . . . is in charge of the nation’s monetary policy, taking actions almost daily to help determine how much money is available, how easily it may be borrowed, and how costly it will be.
