What is the maximum height the hill could be
Answer:
below 1,000 feet
Explanation:
On a map, a hill is represented by contour lines that form concentric rings. The hilltop is located inside the smallest closed circle. An area of high terrain is referred to as a hill, which is often less steep and more rounded than a mountain.
What maximum height the hill could be?A hill can only have an elevation that is one higher than the value that would have indicated the following contour line. That is to say, despite the fact that the next contour line is not visible, the maximum elevation of the hill is actually close below its value.
Any point's elevation can be calculated by locating the closest labeled line, counting the lines above or below it, multiplying that number by the contour interval, and then adding or subtracting the result from the closest contour line.
Therefore, The contour lines are incredibly close together on a steep slope.

Which of the following is NOT a common element in the human body? Select all that apply.
Answer:
Helium and carbon dioxide
The elements that are not common in human body are carbon dioxide and helium. The correct options are B and E.
What are elements?A chemical element is a type of atom with a specific number of protons in its nucleus, including the pure substance made up entirely of that species.
Chemical elements, unlike chemical compounds, cannot be broken down into simpler substances by any chemical reaction.
The human body is made up of only six components: oxygen, hydrogen, nitrogen, carbon, calcium, as well as phosphorus.
Sulfur, potassium, sodium, chlorine, and magnesium make up about 0.85% of the remaining mass. All 11 of these elements are necessary.
Carbon dioxide and helium are elements that are not found in the human body.
Thus, the correct options are B and E.

Harry had been learning about joints in one of his classes at school. On the way to the emergency room he tried to recall what types of tissues made up the different joints. He knew ligaments, tendons, and other connective tissues associated with joints often did not heal quickly. He wasn't sure whether it would better to have broken a bone or to have sprained something. Correctly match each tissue type to the sentence. Some of the words may be used more than once.
__________ is what makes up the war criage of synovial joints.
A symphysis is an amphithjoint where__________ joins adjacent bones
Epiphyseal platos are the growth plates of long bones which are made up of ___________ and are an example of a synchondriosis.
a. Dense regular conective tissue
b. hyallne cartilage
c. Dense irrregular conective tissue
d. fibrocartilage
Answer:
The correct answer is -
1. hyaline cartilage
2. fibrocartilage
3. hyaline cartilage
Explanation:
1. The hyaline cartilage covers the articular cartilage of the synovial joint that is translucent or clear as glass-like cartilage that has a firm consistency and a high amount of collagen.
2. A symphysis is an amphiarthrotic joint which is a fibrocartilagenous joint that joins with the adjacent bone. This is a very tough or strong tissue.
3. The growth plate of the long bone or epiphyseal plates are examples of synchondrosis,which is a hyaline cartilage composed tissue.

Water was rediscovered on the Moon in 2020. How is the recent discovery different from the LCROSS discovery and why is it potentially exciting for humans?
Answer:
Both are the same but done by different space agencies.
Explanation:
The recent discovery is same as the LCROSS discovery because both are done in order to discover water on the moon. it is potentially exciting for humans because water is very important for life as well as this water is also can be used for formation of rocket fuel from it which helps the rocket in movement from moon to the earth if the fuel is finished.
A conditional mutation expresses its mutant phenotype only under certain conditions (the restrictive conditions) and expresses the normal phenotype under other conditions (the permissive conditions). One type of conditional mutation is a temperature-sensitive mutation, which expresses the mutant phenotype only at certain temperatures. Strains of E. coli have been isolated that contain temperature-sensitive mutations in the genes encoding different components of the replication machinery. In each of these strains, the protein produced by the mutated gene is nonfunctional under the restrictive conditions. These strains are grown under permissive conditions and then abruptly switched to the restrictive condition. After one round of replication under the restrictive condition, the DNA from each strain is isolated and analyzed. What characteristics would you expect to see in the DNA isolated from each strain with a temperature-sensitive mutation in its gene that encodes the following?a. DNA ligase
b. DNA polymerase I
c. DNA polymerase III
d. Primase
e. Initiator protein
Answer:
a) DNA ligase
Due to temperature sensitivity DNA ligase action is impaired due to presence of multiple nicks but the DNA replication will proceed
b) Encoding polymerase I
Due to temperature sensitivity mutation occurs causing non-corrected strands to be obtained but DNA replication will continue
c) Encoding polymerase III
Replication is stooped here because of the importance of the enzyme in the synthesis of new strand
d) Primase
The enzyme will induce primers in forward and lagging strands
Explanation:
DNA replication is facilitated by the functionality of enzymes in assisting the formation of new synthesis

Explanation:
The surprisingly low rates of genetic differences between different current human populations (about only 6.5%) and that most genetic diversity occurs person-to-person within a population rather than population to population points to:
A.
a common origin of Homosapiens sapiens in Africa from a small number of people
B.
a fairly high rate of gene flow between human populations
C.
a fairly short time, perhaps 200,000 years existing as a new species in Africa
D.
all of the above
Answer:
the answer for this question would be B.
a fairly high rate of gene flow between human populations
Genetic diversity is the result of heritable traits that vary within species. It is seen more in person-person than in population because the human population has a high rate of gene flow. Thus, option B is correct.
What are gene flow and drift?Gene flow is the passing of the heritable traits outside and inside the population due to factors like migration or because of the gametes. The alleles possessing the characters are moved from one population to another.
In genetic drift, the allele frequency experiences an alteration in the genetic pool of the population. High genetic flow and the drift in humans result in genetic diversity. It causes very neutral differences to appear and are most likely to be seen in person rather than in the whole population.
Therefore, the high gene flow results in genetic diversity in the person.
