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.

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.
Duchenne Muscular Dystrophy (DMD) is a sex-linked trait that causes muscular weakness that gets worse as a person ages. Which is most likely true of Duchenne Muscular Dystrophy? A. DMD can only be inherited by females. B. Females with DMD always have a mother with DMD. C. The gene for DMD is located on the X or Y chromosome. D. The gene for DMD is most active in the cells of the reproductive organs.
Answer: C
Explanation:
DMD is s*x linked trait. This means that we have to consider the chromosomes XX and XY. For a male to have DMD, this means the mom must must pass down the allele for DMD. The mom can either be a carrier OR she has to have DMD and the dad can only pass down the Y chromosome. For a daughter to get DMD, this means the dad has to have the allele for DMD and so does the mom. That means that the dad has DMD and the mom can either have DMD or be a carrier. Based off of this logic, we know that the answer isn't B. Because they tell us DMD is s*x-linked trait, it means that the gene for DMD is on the x or y chromosome.

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.

1. Which of the following may not likely be possible when a tall man marries a short woman ?
A) All the progeny may be tall.
B) All the progeny may be short.
C) Some of their offspring may be short.
D) Some of their offspring may be short.
NOTE: EXPLANATION IS REQUIRED.
Answer:
The gene for having a tall stature is a recessive trait. So the man can have only as genotype "aa". The short woman can have instead as genotype either Aa or AA. in the first case, we have both tall and short children while in the second case only short children.
So the answer is A) All the progeny may be tall.

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

after decomposition in the carbon cycle, put the following steps in order.
- photosynthesis
- fossil fuels or volcanic eruption
- respiration
The correct answer is after decomposition in the carbon cycle, it is first fossil fuels or vulcanic eruption, respiration, and photosynthesis.
Explanation
The carbon cycle is the way that carbon circulates through the atmosphere, oceans, and the Earth's surface and interior through chemical, physical, geological, and biological processes. This cycle is very important because carbon is present in all elements of the Earth. Decomposition is the stage in which organisms (plants and animals) break down and are absorbed by the soil. After millions of years, the carbon contained in these organic wastes becomes the mineral coal that is exploited in mines and extracted for use as fossil fuels, another part of this compound mixes with the processes of the lithosphere and is expelled. in volcanic eruptions. Also, once absorbed by the soil, it feeds the plants that serve as food for different animals that use it for one of their basic processes such as respiration. Once in the atmosphere, the plants absorb carbon again to make their photosynthesis. Therefore, the correct order of the steps of the carbon cycle is Fossil fuels, respiration, photosynthesis.
In eukaryotes transcription takes place in the _________. translation takes place in the ________.
1. cytoplasm/cytoplasm
2. nucleus/cytoplasm
3. nucleus/ribosomes
4. ribosomes/nucleus
Answer:
3
Explanation:
The correct answer will be option-Transcription takes place in the nucleus, and translation takes place in ribosomes.
The regulation of genes is regulated and controlled by two main processes of central dogma called transcription and translation.
Transcription is the process of formation of messenger RNA or mRNA from a single strand of DNA whereas translation is the formation of protein from mRNA.
This process takes place in different sites in prokaryotes and eukaryotes. In prokaryotes, both transcription and translation take place in the cytoplasm but in eukaryotes, the transcription takes place in the nucleus whereas translation takes place in the ribosomes present in the cytoplasm.
Thus, the selected option is the correct answer.
