Answer:

The wax vapor catches light and burns, sending a flame high above the wick. Heat from the flame travels in three directions at once by processes called conduction, convection, and radiation. Convection draws hot wax vapors out from the wick and sucks oxygen from the surrounding air into the base of the flame.

Explanation:

Answer:

The heat from the wick melts the wax which gets absorbed in the wick and then gets burnt (which is really oxidation) to produce heat energy as well as light energy. The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light.

According to the research, the correct answer is the enzyme in charge of transcription in bacteria in the synthesis of any RNA is RNA polymerase, unlike eukaryotic cells, in which there are different types of enzymes depending on the type of RNA transcribed .

Bacteria have a single type of RNA polymerase, which is a complex enzyme made up of several subunits, being responsible for transcription, polymerizes in the 5'-3' direction and does not need primers.

In this sense, transcription in eukaryotes is much more complex than in bacteria, it takes place in the nucleus, transcription is carried out by 3 types of RNA polymerases and it has a more complex regulation, in which numerous transcription factors participate that promote the initiation.

Therefore, we can conclude that in eukaryotes, DNA has to bind to transcription factors and there is a great deal of specialization of RNA polymerases, while in bacteria they have a single type of RNA polymerase.

Explanation:

Chlorophyll absorbs light and converts it to chemical energy. ... During photosynthesis, plants absorb light energy from the sun and convert it into chemical energy in the form of glucose.

The role of chlorophyll during the process of photosynthesis is that it effectively converts the captured radiant energy (light energy) from the sun to chemical energy.

Chlorophyll may be defined as the type of green-colored pigment which is present in all green plants, some algae, and cyanobacteria. It is present in the chloroplast of the plant and carries out the entire process of photosynthesis.

This green-colored pigment is generally made up of porphyrin rings with magnesium being the co-factor. A chain of carbon and hydrogen is also present. This is known as the Phytol tail. The function of chlorophyll in each photosynthetic organism remains the same throughout.

Therefore, the role of chlorophyll during the process of photosynthesis is that it effectively converts the captured radiant energy (light energy) from the sun to chemical energy.

Answer:

they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes

Explanation:

G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.

A scatter plot is used to display a correlation between two continuous variables, as shown in the given problem. A line of best fit is a straight line that passes through most of the data points in a scatter plot, indicating the direction and strength of the relationship between the two variables.

In order to determine the line of best fit in a scatter plot, one needs to draw a line that best represents the overall pattern of the data points. To illustrate, one might consider the following three graphs:In the first graph, the line of best fit is relatively flat, indicating a weak correlation between the two variables. This means that weight does not increase or decrease in direct proportion to height, but rather varies more independently.In the second graph, the line of best fit is more diagonal, indicating a stronger correlation between height and weight.

This means that as height increases, weight also tends to increase, although the relationship is not necessarily linear.In the third graph, the line of best fit is steep, indicating a very strong correlation between the two variables. This means that as height increases, weight tends to increase at a faster rate.

The answer to the given question would depend on the slope of the line of best fit in the scatter plot provided. However, it is not possible to determine this without the scatter plot itself. In this case, the line of best fit would be a good predictor of weight given height.

Explanation: the one starting from 130 and going up

The table Paramecium Contractile Vacuole Contractions which correctly describes the bars on a bar graph representing the data is the bars range from tallest for very high concentration to shortest for very low concentration.

The data in the table records the number of contractions per minute of a paramecium's contractile vacuole in response to different salt concentrations in the surrounding environment.

A bar graph representing this data would have five bars, one for each level of salt concentration.

The bars would vary in height according to the number of contractions per minute, with the tallest bar representing the highest salt concentration and the shortest bar representing the lowest salt concentration.

Therefore, the correct statement describing the bars on the bar graph would be: "The bars range from tallest for very high concentration to shortest for very low concentration."

This statement accurately describes how the height of the bars would vary based on the data in the table.

The other statements do not accurately represent the data or the trends observed in the table.

Given:

Jacky leaves the office at 4:15 PM and she reaches her house at 4:55 PM.

Distance between office and her house = 25 km

To find:

The driving speed of Jacky.

Solution:

The difference between 4:15 PM and 4:55 PM is 40 minutes.

60 minute = 1 hour

1 minute = \(\dfrac{1}{60}\) hour

40 minute = \(\dfrac{40}{60}\) hour

                 = \(\dfrac{2}{3}\) hour

We know that,

\(Speed=\dfrac{Distance}{Time}\)

\(Speed=\dfrac{25}{\dfrac{2}{3}}\)

\(Speed=\dfrac{3\times 25}{2}\)

\(Speed=\dfrac{75}{2}\)

\(Speed=37.5\)

Therefore, the driving speed of Jacky is 37.5 km per hour.

Based on the information provided in the chart, the light-dependent reactions of photosynthesis occur in the thylakoid membranes of the chloroplasts, and require water (H₂O) and sunlight as inputs.

The outputs of the light-dependent reactions are oxygen (O₂) and ATP (adenosine triphosphate), which is a molecule that stores energy for use in other cellular processes.

The light-independent reactions, also known as the Calvin cycle or the dark reactions, occur in the stroma of the chloroplasts, and use the ATP and carbon dioxide (CO₂) produced in the light-dependent reactions as inputs. The outputs of the light-independent reactions are sugar (C₂H₂O) and oxygen (O₂), which is released as a byproduct.

What is photosynthesis?

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of organic compounds such as glucose (a type of sugar). It is a fundamental process in the biosphere, as it is the primary means by which energy from the sun is captured and converted into a form that can be used by living organisms.
