  • Genetics problem?

     in a cross between two true-breeding plants, one with white flowers and another with purple flowers, the following F2 results were obtained: 925 plants with purple flowers, 288 plants with red flowers, and 387 plants with white flowers. Develop a hypothesis to explain the inheritance (mechanism) of flower color in these plant and analyze the data to determine if they fit the hypothesized mechanism.

    What is the probable mechanism of inheritance of flower color in these plants?

    A)Flower color in these plants is due to inheritance of one gene with a completely dominant allele.

    B)Flower color in these plants is due to inheritance of one gene having an incompletely dominant allele.

    C)Flower color in these plants is due to inheritance of two genes, each with completely dominant alleles.

    D)Flower color in these plants is due to inheritance of two genes that show epistasis.

    E)Flower color in these plants is due to inheritance of two genes that complement one another.

  • Need help with physics problem?

    A meter Stick is used to balance.

    The fulcrum support is located atthe 8 O. O cm mark. A mass of400 grams is hanging from the 90. 0 cm mark and this balances the stick.

    a. What is the mass of the stick?

    b. Wh.at is the force exerted by the fulcrum support at the point of contact with the stick? 

    C. What is the torque appli ed to the Stick by the hanging mass?(axis at Pivot/ fulcrum).

    d. Don't Change anything. Consider a new axis about which the is System not rotating(it is balanced) is at the 0.0 O m end of the stick(fulcrum has not moved). There are three forces applying torques to the stick. What are the torques for each?

    What is the net torque?

  • Chem help?

    A small amount wet of hydrogen gas (H2) can be prepared by the reaction of zinc with excess hydrochloric acid and trapping the gas produced in an inverted tube initially filled with water. If the total pressure of the gas in the collection tube is 789.7 mmHg at 25°C, what is the partial pressure of the hydrogen? The vapor pressure of water is 23.8 mmHg.
