First, it is necessary that this scientist decide on what point of the Cretaceous period he wants to study. Among several points he may want to study the evolution of microorganisms of that time, the life of a dinosaur species, or the evolution of dinosaurs, the flora that was established during this period, among others. This is the phase of the scientific method called Observation.
After that, he must enter the phase called "Elaboration of hypotheses" where he will raise questions about the point he decided to study. "How many flower species existed in that period?", "How many of these flowers can we observe today?" among others.
After that, he will enter the phase called "Experimentation", where he will establish a type of experiment and all the experimental factors and variables that will allow the hypotheses to be answered.
After the experiment he will collect the data that will be analyzed and that will give results that will answer the hypotheses previously established. This is the phase called "Analysis of the results".
At that moment, he will be able to reach the last phase of the scientific method, the phase called "conclusion", where he will show the conclusions that the experiment allowed to be established.
Answer:
Her minimum height must be 5'5" and her minimum weight must be 150 lb
Explanation:
The double red program is a program where red blood cells are donated by people . This red blood cells are used for treatment of patients that require red blood cells such as transplant of organs, transplant of tissues, treatment of cancer e.t.c.
Apheresis is a process whereby blood is collected or removed from the body and it undergoes the process of filtration into various components of the blood.
The machine that is used during apheresis collects the human blood and separates it into white blood cells, red blood cells and platelets.
A field habitat vegetated by grass and other non-woody plants (grasslands) is known as a meadow. They are of ecological benefit as they are open, sunny regions, which fascinate and support fauna and flora that could not survive in other conditions.
In the given case, when a fungus colonizes the meadow and destructs the majority of its vegetation, which comprises species of small shrubs and grasses, then this may result in the decline of herbivore species due to lack of vegetation on which they survive, which will eventually result in the reduction of carnivore species, as they feed on herbivores.
Answer:
The correct answer is c. water to move out of the strawberry, making it smaller
Explanation:
Osmosis is the process refers to the movement of liquid molecule from the area of high solute concentration to an area of low solute concentration through a semipermeable membrane to equalize the osmotic balance.
Osmosis is important for any cell to maintain a proper osmotic balance of the cell. So if sugar is sprinkled on a strawberry the solute concentration outside the strawberry cells will increase which will result in water release from the cell.
This release of water from the cell will shrink the strawberry and make it small. Therefore the correct answer is c.
The concentration of water is greater outside the cell than inside the cell
