Answer:The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
Explanation:
Answer:
1. Surface (substratum) is preconditioned by environment molecules.
4. Microbes attach and detach from the preconditioned surface.
2.Quorum sensing and the establishment of the extracellular matrix commences as microbes attach more stably.
3. Biofilm matures and some microorganisms escape to the plank-tonic state.
Explanation:
Biofilm is a process in which microorganism irreversibly attach and grow on the surface to produce extra cellular polymers that facilitate formation of matrix. The biofilm process takes three days for the formation after which thickness of plaque increases. There are 4 main steps in biofilm formation. Surface is preconditioned by environment molecules. The microbes attach the preconditioned surface. Establishment of extra cellular matrix and finally biofilm matures.
Answer:
Option D
Explanation:
When amniotic sac breaks and its internal fluid spilled then there are high chances that the fluid may enter into the throat of the infant and may block his/her air passage way. Therefore, in such situation a standard solution is formulated which requires the doctors to suction the air passageway of infant and restrict it from getting choked and contaminated with meconium. A valve mask is primarily used before suctioning
Hence, option D is correct
Answer:
biology is not a physical science, as physical sciences deal with nonliving things such as atoms and whatnot. biology is a biological science
