The term used to describe the organisms overall attempt at maintaining balance or equilibrium of it's internal environment is called Homeostasis.
The foreign molecule that activates the immune system are Antigens.
Answer:
DNA is made up of sugar-phosphate backbone and the phosphate in the DNA contains the negative charge, therefore, DNA is a negatively charged molecule present in the nucleus.
This negative charge is very important in separating the DNA according to their charge and size during gel electrophoresis. During gel electrophoresis DNA of different size is run on an agarose gel in the presence of current and DNA fragments move toward positive charge due to negative in nature.
Small size DNA moves fast through the gel large size DNA moves slow towards negative pole, therefore, separating the DNA according to their size. In gel electrophoresis, red pole is positive pole and the black pole is negative so runs to the red phrase is signifying that the DNA is always run towards the red pole.
Answer:
A. From the capsule to the larger cup
Explanation:
Solvent movement occurs from region of higher concentration to that of its lower concentration. In the given example, the liquid capsule has higher solvent concentration since it does not have solute. Presence of solute in larger cup makes it hypertonic solution with respect to the liquid inside cup. Hence, solvent will move from hypotonic solution (liquid in capsule) to hypertonic solution.
A human's body temperature over the course of 24 hours is
usually highest: mid to late afternoon.
Every person’s body temperature depends on their age, age, exertion,
infection, sex, time of day, and reproductive status of the subject, the place
in the body at which the measurement is made, the subject's state of
consciousness (waking, sleeping or sedated), activity level, and emotional
state.
