Answer: we know that the same temperature was named 0°C and 32°F. We write it 0°C = 32°F, and read it: "A temperature of zero degrees Celsius is the same as a temperature of 32 degrees Fahrenheit." Similarly, 0°F = 160/9°C. ... 23°C is 23°C above 0°C. But 23°C = 23*1.8°F and 0°C = 32°F.

Answer:</h2><h2>Human blood grouping is mainly based on the antigens present on their RBC (red blood cells) and in plasma into various groups but the main antigens are namely A/B and Rh antigens.</h2><h2 /><h2>Depending on A/B antigens humans are grouped (ABO Grouping) into</h2><h2 /><h2>A group: those having A named antigen on their RBC.</h2><h2 /><h2>B group: those having B Antigen on their RBC.</h2><h2 /><h2>AB group : Those having both A B antigens on their RBC.</h2><h2 /><h2>O group: those having no antigens on their RBC.</h2><h2 /><h2>Depending on the presence of Rh antigens they are grouped into Rh positive or negative group.</h2><h2 /><h2>So if the person has both A and Rh antigens then he will be A positive blood group. But having only A antigen but not Rh Antigen then he will be A negative group.</h2>
<h2>Extra Information:</h2><h2>In addiition to these there is also the HH group. The peculiarity is that they do not express the H antigen. As a result they cannot form A antigens or B antigens on their red blood cells. Thus they can donate blood to anybody with ABO grouping but can receive blood only from Bombay blood group people.</h2><h2 />
Answer:
Spontaneous generation, the hypothetical process by which living organisms develop from nonliving matter.
Explanation:
In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. One jar was left open; the other was covered with a cloth. Days later, the open jar contained maggots, whereas the covered jar contained no maggots. He did note that maggots were found on the exterior surface of the cloth that covered the jar. Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation.
