What does it mean that earlobe attachment is a continuous trait?​
mylen [45]

Answer:

If you decided that the continuous spectrum of earlobe shape was a more accurate way to describe the variation, you aren’t alone. Family and genetic studies show that earlobe attachment is actually not a simple trait, but rather a complex trait, affected by multiple genes and environmental factors.

Name two structural and two functional properties of proteins
Inga [223]
1.Proteins are linear polymers built of monomer units called amino acids. The construction of a vast array of macromolecules from a limited number of monomer building blocks is a recurring theme in biochemistry. Does protein function depend on the linear sequence of amino acids? The function of a protein is directly dependent on its threedimensional structure.<span>Remarkably, proteins spontaneously fold up into three-dimensional structures that are determined by the sequence of amino acids in the protein polymer. Thus, </span>proteins are the embodiment of the transition from the one-dimensional world of sequences to the three-dimensional world of molecules capable of diverse activities<span>.

</span>2.Proteins contain a wide range of functional groups<span>. These functional groups include alcohols, thiols, thioethers, carboxylic acids, carboxamides, and a variety of basic groups. When combined in various sequences, this array of functional groups accounts for the broad spectrum of protein function. For instance, the chemical reactivity associated with these groups is essential to the function of </span>enzymes,<span> the proteins that catalyze specific chemical reactions in biological systems</span><span>

Mrs. Jones blood typing results showed agglutination with the plasma containing anti - B antibodies only. What is her blood type
MakcuM [25]

Answer:

Mrs Jones Blood type= B type.

Safe transfusion from: B and O blood type.

Explanation:

In the given example, the anti-B antibodies are present in the donor plasma.  Since anti-B antibodies react with B antigen present on the RBCs of blood, Mrs. Jones should have B antigen on the surface of her RBCs. The blood type with only B-antigen on the RBC's surface is blood type "B".  

Hence, her blood type is "B" type which has B antigens that react with anti B antibodies of the donor plasma causing agglutination and hemolysis of RBCs.  

She can get the blood of B and O blood types. Blood type O is a universal blood type as it does not have B or A antigens on the surface of its RBCs to initiate the agglutination.

A metal body of mass 81 g occupies a volume of 30 cm3. Identify the metal.
Cerrena [4.2K]

Answer:

Aluminum

Explanation:

The density of Aluminum is 2.7 g/cm3

We know the volume and mass of the unknown metal, as density is mass/volume:  81g/30cm3 = 2.7 g/cm3 which is the density of Aluminum :)
