Answer:
Answer
Explanation:
<em> Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.</em>
Answer:
Independent variable: Salinity/Salt concentration
Dependent variable: hatching rate
Explanation:
As rightly stated in this question, INDEPENDENT VARIABLE, in an experiment, is the variable that the experimenter changes or manipulates in order to bring about a measurable response while the DEPENDENT VARIABLE is the variable that the experimenter measures in an experiment. Dependent variable as the name implies is dependent on the independent variable.
In this question where an hypothesis was given as follows: "Hatching brine shrimp is related to salinity (how salty the water is), then the greater the salt concentration, the higher the hatching rate". The hypothesis relates the independent and dependent variables i.e. it tells us how the independent variable affects the dependent variable.
Hence, according to the hypothesis, it is telling us how a change in SALINITY OR SALT CONCENTRATION will affect HATCHING RATE. Therefore;
Independent variable: SALINITY/SALT CONCENTRATION
Dependent variable: HATCHING RATE
Solution:
The type of membrane that protects internal organs from friction is known as serous membrane.
It is the transparent liquid that is found in the body cavities. When looking for a direct location, it is mostly found in the heart, lung, and abdominal cavity. Serous fluid acts as a lubricant for organs. By lying within the membrane near the organ, it helps the organ move easily for functioning and reduces stress and friction the organ may have against other organs. The lungs, for example, constantly move to provide air for the body. This fluid allows for this motion and prevents the wear and tear that might occur without serous fluid.
Although serous fluid is important for lubrication, it also can be very harmful to the body. Some diseases cause the serous glands to produce too much serous fluid. As a result is that the membranes that hold the serous fluids are not allowing the organ to move or function properly. This could not only be serious for our lungs but also for our heart that needs to move to supply blood to the body.
This is the required answer.
