Why is it important that oxygen and carbon dioxide levels be closely regulated in the human body?
A) Both gases are needed for the proper functioning of cell processes
B) Oxygen is needed for cell processes and carbon dioxide is a waste product
C) Both gases are waste products that need to be removed from cells
D) The carbon and oxygen from the gases are needed to build new molecules.
Answer:
B) Oxygen is needed for cell processes and carbon dioxide is a waste product
Explanation:
Cellular respiration refers to the cellular mechanism by which organisms combine molecular oxygen (O2) with organic compounds obtained from foods, it is a chemical reaction that releases 1-energy (ATP), which is used by cells to carry out its functions, 2-carbon dioxide (CO2) and 3-water (H2O). During the gas exchange, O2 is first transported from the lungs to the blood cells, which subsequently deliver nutrients and O2 to all cells of the body. Simultaneously, CO2 diffuses from cells to tissue capillaries, and then this waste product passes from the bloodstream to the lungs where is eliminated.

In maize, yellow kernel color is dominant to white, and wrinkled kernel shape is dominant to the smooth form. Considering both of these traits jointly in self- fertilized dihybrids, the progeny appeared in the following numbers: 193 white, genes assort independently? Support your conclusion using appropriate statistical analysis. wrinkled; 184 yellow smooth; 556 yellow, wrinkled: 61 white smooth
Answer:
yellow, wrinkled are high in population whereas white smooth is lower in population.
Explanation:
Due to self-fertilized dihybrids, the offspring are yellow wrinkled, hybrid and white smooth. 556 yellow, wrinkled are high in population because of the dominant allele while on the other hand, 61 white smooth are obtained and less in number due to recessive nature that comes very little in the population. 184 yellow smooth and 193 white, wrinkled are the hybrid offspring that has both different characteristics from their parents.

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
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.

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
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.

DNA's genetic information is copied to form ___ RNA, which then delivers it to the ___ where protein synthesis occurs.
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.
