Answer:
False
Explanation:
Mendel realized that the F2 had a phenotypic ratio 3:1, meaning 3/4 = 75% were yellow and 1/4 = 25% green.
Mendel observed that the F1 expressed only one of the alternative variants (in this case, only yellow seeds appeared), while the other variant (green) disappeared. Mendel named dominant the expressed variant. Mendel allowed auto pollination and observed that in the second generation, F2, the other disappeared variant reappeared. Both alternative variants were present in the F2. Mendel named recessive the second alternative variant.
Mendel thought that hereditary traits determined by discrete factors were the possible explication for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.
Mendel concluded that each individual (plant) has a pair of factors (alleles), one for each trait (yellow and green) and that the pair separates (segregates) during the formation of the gametes. This conclusion is known as the segregation principle (First Mendels´ Low).
Answer:
Vaccines stimulate the body's own immune system to protect the person against subsequent infection or disease." ... The immune system develops antibodies to the disease so that it cannot make you sick again. Immunization describes the actual changes your body goes through after receiving a vaccine.
Answer:
Phospholipid bilayer
Explanation:
Liposomes are vesicles are spherical in shape. They consist of at least one phospholipd bilayer most especially phosphatidycholine. Liposomes are artficial vesicles similar to a membrane, because it has an hydrophilic core surrounded by a hydrophobic lipid bilayer.
Liposomes are artificial prepared and are used for the transportation of substances like drugs and nutrients between cell parts, outside of the cell and into the cell.
In liposomal drug delivery, the liposome fuses with other internal cell membranes at the site of action and releases its liposomal content.
True. Because its staying still
