a group of students found the specific gravity of a pice of galena to be 7.8. The accepted value for the specific gravity of galena is 7.2 find the % of error in the student's work
Answer:
Percent error = 8.3%
Explanation:
Given data:
Accepted value of specific gravity = 7.2
Measured value of specific gravity = 7.8
Percent error = ?
Solution:
Percent error = measured value - accepted value / accepted value × 100
Now we will put the values in formula.
Percent error = 7.8 - 7.2/7.2 × 100
Percent error = 0.6/7.2 × 100
Percent error = 0.083 × 100
Percent error = 8.3%

Which statement is true about the appendicular skeleton of the human body?
Answer:
I am pretty sure it is, The consists of the bones that form the limbs and the bones that attach the limbs to the axial skeleton. But I am not positive, I hope this helps!!
Explanation:
Option C, It consists of the bones that form the limbs and the bones that attach the limbs to the axial skeleton.
The part of the vertebrate skeleton that has the bones that hold up the body is the appendicular skeleton, which comprises the elements within the limbs, pelvic and pectoral girdle. It holds the bones that produce and uphold the libms and joins them with the axial skeleton. The appendicular skeleton has 126 bones and helps manipulate the upper limbs.
As a college student, you are no doubt concerned about the grades that you earn while completing your coursework. If you wanted to know how overall GPA is related to success in life after college, how would you choose to approach this question and what kind of resources would you need to conduct this research?
I am not a college student, I am a Freshman in High School but if I were in college this is what I would say:
In college the GPA of the student is very important and it helps a student obtain good colleges and courses in this regard.
The data collected from college alumni about their careers after college would be the required resource in this case.
What is meant by a research resource?
The kind of research one wants to do and the kind of questions in mind guide the kind of resources required for research. Currently, access to any kind of information for anyone is greater than ever before.
Thus, for good research, it's important to collect data from the right kind of resources. It needs to be located, organized, evaluated, and used for the communication of information.
Various places can be a home for a research resource or be research resources themselves. These can be traditional libraries. Whereas, personal experiences can be important research resources.
Print media, which includes journals, books, brochures, newspapers, and magazines are conventional research resources. Currently, electronic sources found on the Internet are being used. Interviews or surveys can also be considered research resources.
Therefore, to understand the impact of GPA on students' careers, we need to collect data on their careers.

Which of the following units are repeatedly joined together to form a strand of DNA?
Answer:
Nucleotides
Explanation:
The nucleotides forming each DNA strand are connected by noncovalent bonds called hydrogen bonds.
Nucleotide is the unit that repeatedly joined together to form a strand of DNA.
What is DNA?Deoxyribose + phosphate group + thymine could be a nucleotide of DNA and defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helix carrying genetic information for the various processes such as growth development functioning and reproduction.
There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.

Francine is developing a model of the carbon cycle, which involves the movement of carbon among various Earth systems. She begins by drawing the diagram shown below. Her friend Byron evaluates the model, and suggests that she thicken the arrow leading from fossil fuels to the atmosphere. His reasoning is that fossil fuels are being burned at a much faster rate than natural processes are restoring them. If Francine adopts Byron’s suggestion, how could her model be used to explain a significant change to Earth's systems?
Answer:
After adopting the suggestions of Byron the new or revised model would show that using fossil fuels at a rapid rate would lead to higher inputs of carbon dioxide to the atmosphere which will not be removed by the natural process of removing the excess amount of the carbon dioxide by the process of the photosynthesis and other.
The carbon dioxide would increase due to this and cause trapping of the solar heat in the atmosphere which leads to the greenhouse effect to warm the earth. That ultimately changes the climate of the earth.

What is the Epithelial tissue?
What is the Muscle tissue?
What is the Nervous tissue?
Answer:
connective: Tissue that supports, protects, and gives structure to other tissues and organs in the body
epithelial: are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.
muscle: Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.
nervous: Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.
Explanation:
Answer
Connective tissues gives support, protects and gives structure to other tissues and organs in the body.... example bone, cartilage, blood etc.
Epithelial tissues are spread throughout the body. Their functions include secretion (sweat, mucus), absorption (nutrients) and protection (tissues that lie beneath from radiation) in the body.
Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts.
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.

If two heterozyotes for dwarfism have children what proportion of their kids would you expect to be of typical size and not exhibit dwarfism?
Answer:
3/4 or 75%
Explanation:
This question involves a gene coding for height in humans. The allele for normal height (D) is dominant to the allele for dwarfism (d).
If two heterozygotes for dwarfism are crossed i.e. Dd × Dd, the following gamete will be produced by each heterozygote parent:
Dd - D and d
Using these gametes in a punnet square (see attached image), the genotypes of the expected offsprings will be as follows- DD (1) : Dd (2) : dd (1)
(1) DD - typical normal size
(2) Dd - heterozygous normal size
(1) dd - dwarf
The offsprings expected to be of typical size and not exhibit dwarfism are offsprings DD and Dd, which represent 3/4 of the offsprings. Hence, the proportion is 3/4 or 3/4 × 100 = 75%.

the mountains and city B is on the windward side. Which city is likely to have a wetter climate? Explain your answer.
Answer:
City B will have a wetter climate.
Explanation:
This is because in windier areas in tends to get more wet than rocky areas (mountains) where City A lies. Also because more wind will blow more and more clouds in the direction of city B making it rainier there a lot more often than a non windy rocky are.
In soreflies (a hypothetical insect), the dominant allele, L, is responsible for resistance to a common insecticide called Loritol. Another dominant allele, M, is responsible for the ability of soreflies to sing like birds. A true-breeding mute, Loritol-resistant sorefly was mated to a true-breeding singing, Loritolsensitive sorefly, and the singing, Loritol-resistant female progeny were testcrossed with true-breeding wild-type (i.e., mute, Loritol-sensitive) males. Of the 400 total progeny produced, 119 were mute and Loritol-resistant, 114 could sing and were Loritol-sensitive, 81 could sing and were Loritol-resistant, and 86 were mute and Loritol-sensitive.
