What evidence from the experiment shows that conduction occurred? In your answer, be sure to include the materials involved in the transfer of heat through conduction.
Sample Response: The melting of the chocolate pieces one by one showed that it was caused by heat flowing through the foil bridge. The transfer of heat happened between the foil bridge and the chocolate pieces because they were touching each other.
The conduction was made by the foil which was touching the chocolate made the chocolate slowly melt because of the tea light giving heat to the foil the foil conducted it to the chocolate causing it to melt. Thus, option "C" is correct.
What are conduction, convection and radiation?Conduction refers to the transfer of the energy from one end to the other end from the conducting material. Heat energy, and electric energy all of these can conduct. For example - heat transfer from one end of the road to another.
Convection refers to the process in which heat energy is transferred to the liquid in various manners. For example - a geyser transfers the heat energy to the water.
Radiation refers to the transfer of heat in the form of a heatwave. For example - transferring of heat from the light bulb and heater.
Therefore, the given example can help us to understand the distribution of energy on earth.
Thus, option "C" is correct.

Which of the following contributes to antibiotic
resistance?
A- giving antibiotics to livestock
B- taking multiple antibiotics at the same time
C- going to the doctor when an infection appears
Taking multiple antibiotics at the same time contributes to antibiotic resistance. Thus, the correct option is B.
What is Antibiotic resistance?Antibiotic resistance may be defined as a process or strategy of microorganisms that generate the capability to conquer the drugs developed to annihilate them.
Overprescription of multiple antibiotics increases the ability of bacteria or other microorganisms to survive in harsh little conditions. Still, slowly they evolve themselves and resist the situation of the high effect of antibiotic resistance drugs.
Therefore, it is well described above.

The mitochondrial DNA sequence that is shared by two species has a steady mutation rate. Scientists determine the sequences of these two species to be as follows
Species A: CAGGCCATTATG
Species B: CCAGCCTATAGG
Based on this information, which of the following best explains the difference in the DNA sequence between the two species?
A) Species A and B probably share the most recent ancestor because they only differ by three mutations.
B) Species A and B have fewer differences between DNA sequences means that fewer mutations occurred.
C) Species A and B probably have distinct ancestors because they have many differences in mutations.
D) Species A and B are closely related because they differ by five mutations in their DNA sequence.
It is expected that Species A and B have distinct ancestors because they have many differences in mutations (Option C).
What is the mutation rate?The mutation rate makes reference to the number of mutations that appeared in a given nucleotide sequence in a given period of time.
In this case, sequences from Species A and B have 5 mutations and aligned sequences have only 12 nucleotides, which is a considerably high mutation rate to share a common origin.
Nonetheless, information about divergence times might be helpful to determine the origin of these sequences.
In conclusion, nucleotide sequences of Species A and B exhibit many mutations and therefore they do not have the same evolutionary origin (Option C).

what is the difference between an epithelial cell and a cardiomyocyte
The heart is the main pumping organ of the body. The human heart is divided into four chambers two atria and two ventricles. The human heart consists of three layers- epicardium, myocardium, and endocardium.
The middle layer of the heart (myocardium) consists of cardiomyocytes or muscle cells. These cells receive nerve stimulation from the atrioventricular nodes and sinoatrial nodes.
What are Epithelial cells?Epithelial cells form a layer structure which covers most of the surfaces of the body. These cells perform a variety of functions and exhibit different shapes, size and arrangement which makes up different tissues. For example columnar tissues (column-like cells), cuboidal tissues (cube-like cells) and others.
