We need to show that y = x/(x + c) is a solution of dy/dx = (y - y^2)/x. Then,
<span>dy/dx = ((x + c) * 1 - x * 1)/(x + c)^2 </span>
<span>= (x + c - x)/(x + c)^2 </span>
<span>= c/(x + c)^2 </span>
<span>and </span>
<span>(y - y^2)/x = (x/(x + c) - x^2/(x + c)^2)/x </span>
<span>= (x(x + c) - x^2)/(x(x + c)^2) </span>
<span>= (x^2 + cx - x^2)/(x(x + c)^2) </span>
<span>= cx/(x(x + c)^2) </span>
<span>= c/(x + c)^2 </span>
<span>which proves the equality. </span>
Biology is the study of life, and uses the scientific method, the basis of science, to do so. Hypotheses are made, tested, and remade, until a theory is made, which then becomes Scientific law.
Complete question: This can be seen in the attached file below. It's contains the various protists observed in the exercise.
Answer: For a eukaryotic organism to possess a plantlike characteristics shows its ability to manufacture its own food through the process of photosynthesis.
Explanation:
Protists are single- celled or unicellular organisms. They are made up of eucaryotic cells in which the cell structure is complex with a well - defined nucleus. Typical example if protists includes the following:
--> Volvox
--> Spirogyra
--> Euglena
--> Diatoms
--> chlamydomonas
Some protists are said to be plant like and are known as protophyta. Example of such includes Euglena, Spirogyra and chlamydomonas. This is because they have organelles called chloroplasts. This contains chlorophyll which enables them to make their own food through the process of photosynthesis. Photosynthesis is the process by which energy for sunlight is converted to high energy containing organic compounds such as glucose.
Stress is typically associated with elevated levels of epinephrine and cortisol; some physiologists now define stress as any situation that raises cortisol levels.
<h3>What are glucocorticoids?</h3>
Glucocorticoids are part of the innate immune system's feedback loop, which diminishes certain facets of immune function, such as inflammation.
As a result, in medicine, they are used to treat diseases caused by an overactive immune system, such as allergies, asthma, autoimmune diseases, and sepsis.
Stress is typically associated with elevated epinephrine and cortisol levels; however, some physiologists now describes stress as any situation that raises cortisol levels.
Thus, the answer is cortisol and epinephrine.
