Tall height is dominant to short height in pea plants. You have a tall pea plant that you cross with a short pea plant. What is
zheka24 [161]

Answer:

The tall parent was heterozygous

Explanation:

If tall height is dominant to short height the only genotype possible for short height is hh, while there are two possible genotypes for tall height, Hh and HH. When HH is crossed with hh all the offspring are Hh, but if Hh is crossed with hh, a quarter of the offspring is HH, a quarter is hh and half is Hh. If the tall pea plants were HH there would only be tall offspring, but because there are some short offspring we know that the tall pea plants must have a genotype of Hh.

How much 3M NaOH (MW=40) can be made from 10.0mL of a 10M solution?
vaieri [72.5K]

Explanation:

The given data is as follows.

              M_{1} = 3 M,           V_{1} = ?

              M_{2} = 10 M,         V_{2} = 10.0 ml

Therefore, calculate the volume of given solution as follows.

              M_{1} \times V_{1} = M_{2} \times V_{2}

Now, putting the given values into the above formula as follows.

            M_{1} \times V_{1} = M_{2} \times V_{2}

            3 M \times V_{1} = 10 M \times 10.0 ml    

                   V_{1} = 33.3 ml

or,                             = 0.033 L        (as 1 ml = 0.001 L)

Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.

           Molarity = \frac{\text{mass of solute}}{\text{molar mass of solute}} \times \frac{1}{\text{volume in L}}

               3 M = \frac{mass}{40 g/mol \times 0.033 L}

              mass = 3.96 g

Therefore, we can conclude that mass of NaOH is 3.96 g.

Which statement BEST describes the difference between chemotherapy and biological therapy?
const2013 [10]

Answer:

Chemotherapy targets the cell directly; biological therapy tries to help the immune system so it will attack the cancer cells.

Explanation:

Both chemotherapy and biological therapy are approaches used in cancer treatment.

Chemotherapy involves the use of aggressive anti-cancer drugs. It targets cancer cells directly with the goal to destroy them.

Biological therapy, also called immunotherapy, is a type of treatment used in battling diseases by activating or suppressing the immune system. It is also used in cancer treatment. Its goal is to boost the immune system and help it fight against cancer.
