What statement about antibody is true? a it is a carb molecule b it is only found in the human body c it is target specific d it is formed by covalently linking 3 peptides together

The correct answer option is C. They are target specific.

Explanation:

We are to determine whether which of the given statements is true about antibody.

Antibodies are a type of proteins which are present in the body to defend the foreign attacks that are in the form of antigens.  

These proteins have a basic structure which consists of two pairs of polypeptide chains that are linked covalently via disulfide bonds.

Each antibody recognises one specific antigen and this feature is called as antibody specificity.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
