For blood type B, the genotype is BB or BO with A as the antigens and B as antibodies. The blood type AB has the genotype to be AB. The antigens are both A & B, and no antibodies on the blood plasma. The blood type O has the genotype to be OO. There are no antigens but has antibodies to be A or B. Rhesus factor or the 'D' antigen is also found on the surface of the red blood cell. Those with it are seen to be rhesus positive or Rh+ and those without are rhesus negative or Rh-.
Dark of the Moon. The Dark of the Moon is traditionally the last three days of the Lunar cycle, immediately preceding the New Moon, and the time when the night sky is notably absent the presence of the Moon.
When the Moon is directly in between the Earth and Sun, we see a solar eclipse. The Moon appears to pass in front of the Sun and darken it completely. And in the opposite situation, when the Earth is in between the Sun and the Moon, the Earthâs shadow darkens the Moon.ometimes the Moon is above this orbit and sometimes itâs below, so it doesnât block the light from the Sun, or get caught in the Earthâs shadow. The Sun and the Moon work together to create the tides we experience here on Earth.
