how does comparative embryology support the theory of evolution?
Answer:
Comparative Embryology provides strong support for the hypothesis that Darwin put forth to explain the apparent similarities and differences he saw among different species, i.e. that these species are the result of an evolutionary process involving selection (now known to be gene based) for structural.

This model shows the process of protein synthesis including transcription and translation. What is the best explanation for what is
occurring at the arrow (translation)?
Answer: The answer is C
Explanation:
During the process of protein synthesis, the best explanation for what is occurring at the arrow is as follows:
The codon on the mRNA pairs with the anticodon on the tRNA which transfers amino acids into the proper sequence to form a protein.What is Protein synthesis?Protein synthesis may be defined as a biological process through which cells make proteins in order to accomplish metabolic functions that facilitate the survival of living organisms. The process of protein synthesis terminates with the help of two stages. They are as follows:
Transcription.Translation.Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. While the process of translation acquired the transfer of genetic instructions from the mRNA to the sequence of amino acids in order to form proteins. This takes place in the cytoplasm of the cell.

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

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.

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.

In the Northern Hemisphere, the sun is lower in the sky during the winter.
C.
Earth is farther from the sun during the winter.
D.
Earth rotates more slowly during the winter.
E.
The Northern Hemisphere gets less direct sunlight during the winter.
Answer: Option A and E.
Explanation:
Norther hemisphere Is the half of the Earth that lies on the north of the equator. The equator is the line that divide the Earth into two halves.
During the winter, the northern hemisphere is colder because the northern hemisphere move away from the sun and receive less sunlight form the sun. The sun is very high in temperature and it has high heat, when the northern hemisphere move away from it, there is lower heat or temperature that get to it , making it to become cooler or have lower temperature. The countries in the northern hemisphere comprises of all countries in Europe, North America, Asia,part of South America and little part of Africa.

Answer:
Mucous membranes
Explanation:
The epidermis (external) and mucous membranes (internal) represent the first non-specific barriers that act against invading pathogens and harmful substances. The mucous membranes separate the external environment surrounding the mucous cells from the body's internal environment. These membranes are considered as selectively permeable barriers that act to prohibit the passage of pathogenic microorganisms (e.g., bacteria) and harmful agents (toxic chemical substances).
