A cell membrane is very specific about what it allows to cross.how does this help the cell?
Answer:
The cell membrane is selectively permeable . It lets some substances pass through rapidly and some substances pass through more slowly, but prevents other substances passing through it at all. Some small molecules such as water, oxygen and carbon dioxide can pass directly through the phospholipids in the cell membrane
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.
Which of the following explanations is true based upon the graph?
I. Lamb and mutton produce less protein per square meter than pig meat and poultry.
II. More land is needed for plants than combined beef to produce 100 grams of protein.
III . Meat production is less efficient than farming protein from fish and prawns.
A.) I only
B.) II only
C.) I and III only
D.) II and III only
Answer:
B.) II only
Explanation:
More land is needed for plants than combined beef to produce 100 grams of protein because plants produces very low amount of protein as compared to beef that produces large amount of protein. Beef is made up of protein so when we eat it, it provides large amount of protein while on the other hand, plant body is made up of other molecules and very little amount of proteins.
The genes of the ath operon are expressed only when the concentration of athelose in the bacterium is high. When glucose is absent, the bacterium needs to metabolize athelose as an energy source as much as possible. The same catabolite activator protein (CAP) involved with the lac operon interacts with the ath operon. Based on this information, how is the ath operon most likely controlled
Answer:
Athelose and glucose.
Explanation:
The ath operon most likely controlled due to the presence of athelose in small amount because ath operon are expressed only when the concentration of athelose in the bacterium is high. The smaller amount of athelose can be gained if glucose is present to the bacterium in sufficient amount or quantity so we can say that glucose quantity control the amount of athelose and it will control the ath operon.

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.

What conclusions did Watson and Crick reach after reading Franklin’s report discussing the symmetry of DNA?
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.
