Acids are the EXACT OPPOSITE of bases, but they're both still deadly. Base (or basic/alkali) is something in everyday thinks like toothpaste, milk, etc. But too much intake of bases can harm you, and if water has too much alkali, the fish living in it can die. Acidic, on the other hand, is very effective. Acids are usually in oranges, sodas, even your stomach has acids in it. Too much acids can rot your teeth, can cause "heartburn", even can give you a stomachache.
The third hour increased by 20 percent. The second hour was decreased by 10 percent. So third hour decreased and second hour increased.
Answer:
the speed of the fluid in the wider section of the pipe is 1m/s.
Explanation:
By equation of continuity we can write (for ideal (non-viscous, in-compressible).
A_1,A_2 are areas of the pipe at inlet and outlet of the pipe.
_1
Here, d_1 , d_2 are diameters of inlet and outlet, also v_1, v_2 are velocities at inlet and outlet.
putting values we get
solving we get
Answer: is <em><u>Organelles present in single-celled organisms act in a manner similar to organ systems</u></em>
<em><u /></em>
Explanation:
Multicellular organisms organ system play a critical role for the smooth functioning of whole body. Millions of cells combined to make an organism. The role of organ system in whole body is to provides oxygen and nutrients to the cells and eliminates the toxic material such as carbon dioxide. Organ systems like, respiratory system, digestion system, and cardiovascular play an important role in the human body to perform various functions for its survival.
Unlike multicellular organisms the unicellular only consists of single cell e.g. prokaryotic organisms and eukaryotic organisms namely, Amoeba, Euglena, salmonella, Fungi etc. Single celled organisms are able to carry out all processes mandatory for the sustenance of life with the help of single cell only e.g. respiration and digestion.They can survive with the help of single cell. Unlike multicellular organisms unicellular do not require multiple number of cell for its survival.
Answer:
Explanation:
Velocity is defined as the rate of change of displacement.
velocity is a vector quantity, that means it requires both magnitude and direction to completely explain the velocity.
For example, the velocity is 5 ms due east, it means an object is moving with speed 5 ms in the direction of east. We can say that the object covers the displacement of 5 m in one second due east.
