Consider the observations you made working with the collisions theory gizmo.
identify a question about chemical reactions with catalysts that you should be able
to answer through investigation using the collision theory gizmo. consider writing
your questions in an "if this… then will that? " kind of format. model your question
on the example from the practice investigation: "if the temperature is increased will
the half-life time of a chemical reaction without a catalyst be decreased? "

answer: b

coz red blood cells marrow and circulates the body for 120 days.

we solve the problem using the hardy-wineberg equation.

let us start with the homozygous recessive proportion of individuals with sickle cell anaemia,

we have the proportion as q² = 0.25.

∴ q = 0.5 (frequency of hbs in population)

further,

solving for the frequency of normal cell by using the fact that,

p + q = 1

∴ p = 1 - 0.5 = 1 - 0.5 = 0.5

now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous carriers of sickle cell anaemia,

∴ 2pq = 2 x 0.5 x 0.5 = 0.5

and the homozygous normal cell individuals proportion is given by the expression,

∴ p² = 0.5² = 0.25

hence, the carriers for sickle cell anaemia are in proportion, 0.5, or 50%.
