I believe that the odds are strong that the off-spring would be 1/4 black, 1/2 black and white, and 1/4 white:

Bb x Bb = ¼ BB (all black); ½ Bb (black and white ) ;¼ bb (all white).

Determine whether the statement is true or false. Suppose P(t) represents the population of bacteria at time t and suppose P'(t)
Lorico [155]

Answer:

TRUE

Explanation:

If the population follows a logistic growth curve, the graph of P vs t will look like the diagram below.

The rate of growth (P') increases slowly at first, then increases rapidly from 2 to 4, and then slows down, but always P > 0.

The graph has an inflection point at (3, 1000). That's the point at which the rate of growth starts slowing down.

When t < 3, P'' > 0.  

When t = 3, P'' = 0.

When t > 3, P'' < 0, because the rate of population growth is slowing down.

Thus, if the population is in the final phase of logistic growth, the population is increasing at a decreasing rate (TRUE)..

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.
