Anjuli performed an experiment to determine the respiration rate of yeast. She determined this by measuring the
amount of carbon dioxide (CO2) that was produced. Then, she created the following graph.
Her teacher suggested that she redraw her graph as a line graph. Why should she redraw the graph?
• A line graph looks better in a scientific report.
• She was measuring a rate of change.
• She had graphed the wrong relationship.
• Her experiment had many different variables.
Answers
The correct answer is B. She was measuring a rate of change.
Explanation
A linear graph is a type of graph that contains a series of data represented by points joined by linear segments, which allow you to quickly check the change in the trend of the data. Therefore, inline graphs quantitative variables are usually used to see their behavior over time. According to the above, Anjuli had to use a linear graph to express the information in the graph more clearly, because the data that he was using in his graph were quantitative variables. Also, she wanted to express the respiration rate of the yeast per minute. According to the above, the correct answer is B. Ella She was measuring a rate of change.

DNA's genetic information is copied to form ___ RNA, which then delivers it to the ___ where protein synthesis occurs.
Answers
Answer:
DNA's genetic information is copied to form mRNA, which then delivers it to the ribosome where protein synthesis occurs.
Explanation:
During transcription, RNA polymerase uses a single-stranded DNA template to synthesize a complementary strand of RNA. The mRNA then travels from the nucleus to the cytoplasm where ribosomes are found. Ribosomes are structures that are responsible for making proteins.

What conclusions did Watson and Crick reach after reading Franklin’s report discussing the symmetry of DNA?
Answers
Answer:
They formed a revised model.
Explanation:
After seeing Franklin's x-ray images of DNA and her report on DNA's symmetry, Watson and Crick formed a revised model of DNA's structure i.e. a double helix with sugar-phosphate backbones that is running in opposite directions. Watson, Crick, Franklin, and Wilkins are co-discovered the double-helix structure of DNA, which formed a basis for modern biotechnology. Images taken by Franklin allowed James Watson and Francis Crick to create their two-strand, or double-helix, model.

Answers
Answer:
Independent Variable
Explanation:
The independent variable is what we are changing or what is being tested.
The control/constant group is when you do not change anything and you want to see how the object acts under normal conditions.

Scenario: Kenneth and Catherine Lohmann of the University of North Carolina explored the orientation or direction-finding abilities of loggerhead sea turtle hatchlings under varying magnetic conditions. Hatchlings were placed in a tank of water in a laboratory either in the natural magnetic field of the earth OR in a reversed magnetic field in which north and south were flipped. The researchers then measured the direction that the hatchlings swam. The experiments were carried out in the dark and at night since that is when most newly hatched turtles migrate from their sandy nests into the ocean. What is the variable being tested in this experiment
Answers
Answer:
Variable being tested: The direction taken by the hatchlings under different magnetic fields.
Explanation:
The independent and the dependent variables are the two principal factors needed in an experiment.
Independent variable: Refers to all the variables in an experiment that provoke a response in another variable. The independent variable changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. Dependent variable: Refers to the variable that reacts to the changes produced in the independent variable. Depending on how the independent variable is modified, the dependent variable change. It is usually identified by the letter Y.In the exposed example, we know that
Goal: To explore the orientation or direction-finding abilities of loggerhead sea turtle hatchlings under varying magnetic conditions.
Experiment:
The hatchlings were placed in water tanks in the laboratory, under dark conditions and during the night.
Tanks in a natural magnetic field Tanks in a reversed magnetic field ⇒ north and south were flippedObservations were done about the swimming direction of the hatchlings
Variable being tested: The direction taken by the hatchlings under different magnetic fields.
In this experiment, the independent variable is the magnetic field conditions. The alternative conditions -how this variable is modified- are the Natural magnetic field and Reversed magnetic field. Researchers are no interested in the magnetic field, they are interested in analyzing how the change in the magnetic field affects the turtles´ orientation. Then, we can assume that the dependent variable is the direction taken by the turtles. It depends on the change in the magnetic field. Researchers are interested in testing how the change in the magnetic field affects the orientation of the turtles. This is the variable being tested in the experiment.
Orientation abilities of loggerhead sea turtle.
Kenneth nd catherine are working on a university project to the find out the orientation or the direction finding abilities of the logger head sea turtle as their hatchlings lay indifferent magnetic conditions. They are placed in differences environments. They are also kept in revere magnetic fields.
Thus answer is based on the magnetic field.
As per the exploration and findings the abilities of the sea turtle were carried out in the dark night and since they migrate to their nest in the ocean the variables such as Independent Variable was analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. The dependent variable showed the changes that took place due to the changes in the independent variable and these were related to the use of light, distance and navigational direction.Hence the option is A magnetic field.Learn more about the Kenneth and Catherine.

Which of the following statements is true? Which of the following statements is true? No archaea are capable of using CO2CO2 to oxidize H2H2, releasing methane. Prokaryotes have low levels of genetic diversity. Archaea and bacteria have identical membrane lipids. The cell walls of archaea lack peptidoglycan.
Answers
Answer:
The correct answer is - The cell walls of archaea lack peptidoglycan.
Explanation:
Archaea are the prokaryotes that are different from bacteria in various ways but the most important differences are the membrane lipids and the major component of the cell wall that lacks peptidoglycan found in the cell wall of bacteria.
These prokaryotes are able to use carbon dioxide to oxidize hydrogen, releasing methane. Archaea-like prokaryotes have a high level or complex genetic diversity.

Ethan began making a model to show the processes which resulted in the formation of oceans
Which of the following would be the next step in the process?
Crust is broken down
Earths crust moves
Earths plates meet
Sea floor spreading
Answers
The next step in the process is sea floor spreading. The correct option is D.
What is sea floor spreading?Tectonic plates, which are huge chunks of the lithosphere of the Earth, split apart from one another during the geologic process of seafloor spreading.
The oceanic basin is the result of sea floor spreading.
The ocean crust and its basins are formed when the sea floor spreads and separates after the basin has been filled with water.
All of these result from various plate interactions within the planet.
New ocean floors are created by volcanic activity at spreading centers at divergent borders after the crust has developed and accumulated water.
The production of fresh crust occurs close to the margin, and subsequent crusts push against and away from it. Ocean basins are created by the development of new ocean floors.
Thus, the correct option is D.
