Sheena wants to measure the volume of a ball that is 24 cm across. How should she set up her equation?
Semmy [17]
Given that Sheena's ball is a sphere, its volume can be obtained by using the formula: V_ball = (4/3)*pi*r^3, where, r is the radius of the sphere. Since the ball is 24 cm across, this means that the radius is half of the diameter which is equal to 12 cm. Thus, the volume of the ball is equal to 7238.2295 cm^2.

iren2701 [21]

Answer:

  • 25 tall individuals, TT
  • 50 medium individuals, Tt
  • 25 short individuals, tt

Explanation:

<u>Available data</u>:

  • The size of this species was determined by a single gene
  • TT- Tall
  • Tt- Medium
  • tt- Short
  • Total number of individuals in the progeny, N = 100

There are three phenotypes and only one gene, so it seems that this is an example of incomplete dominance, where the medium-size is the intermediate form between tall-size and short-size.  

Cross: between two medium Gazorps

Parentals) Tt    x    Tt

Gametes) T  t       T   t

Punnett square)    T           t

                    T       TT         Tt

                    t        tT          tt

F1) 1/4 = 25% TT, tall

    2/4 = 1/2 = 50% Tt, medium

    1/4 = 25% tt, short

100% of the progeny ------------ 100 individuals

25% Tall, TT ------------------------X = 25 individuals

50% Medium, Tt -------------------X = 50 individuals

25% Short, tt ------------------------X = 25 individuals
