The correct answer is their blood lacks A or B antibodies.
People with type AB blood have A and B antigenes on the surface of red blood cells (RBCs). Antigen AB has no antibodies, thus, transfusion can be considered safe ( the serum of the recipient does not contain antibodies for the blood cell antigens of the donor).
Specialized structures for reproduction: One example is a fruiting body. Just like a fruit is involved in the reproduction of a fruiting plant, a fruiting body is involved in the reproduction of a fungus. A mushroom is a fruiting body, which is the part of the fungus that produces spores (Figure below
<span>Na+, cl-, hco3-, and k+ are electrolytes. Na+ is sodium. Cl- is chloride. Hco3- is bicarbonate and k+ is potassium. Electrolytes are needed for our organs and cells to function like they should. We obtain some of these electrolytes through the food we eat, such as sodium from salt and potassium from bananas.</span>
Answer:
Compound: These are made of the various type of same or different elements. These elements show a specific ratio in a particular compound.
The physical properties are traits of a particular compound or element that can be observed physically like the state of matter, color, odor, and other. The chemical properties and physical properties of compounds and elements they formed are different.
It is not comparable as the elements have no or very little individual value in a compound. For instance, water made of hydrogen and oxygen, where water is liquid and constituents are gas.
The importance of the semi-conservative model is unhealthy old and new genes cancel each other. The result new cells are disease and mutation free. ... DNA replication is semiconservative because DNA is composed of two complementary strands, each of which acts as template to construct a new strand complementary to itself.
