You may wish to construct the punnett squares on scratch paper first before you fill in the punnett squares on the
lab report. answer the questions below. when you are finished, submit this assignment to your teacher by the
due date for full credit.
part 1: monohybrid cross-predicting dimples in an f1 generation
apply your understanding of how alleles assort and combine during reproduction to evaluate a scenario involving
a monohybrid cross.
the allele for having dimples (d) is dominant over the allele for no dimples (d). some characteristics in people
are inherited as simple dominant and recessive traits. one example is dimples. dimples is a dominant trait, and
the lack of dimples is a recessive trait. in this example, a person with dimples is represented as either dd or dd,
and a person with no dimples is represented as dd
total score:
of 20 points
(score for question 1: of 2 points)
1. imagine a mother and a father who both have dimples and are heterozygous for the trait, or dd. they are the
p generation, or parent generation. create a punnett square to show their offspring, the f1 generation.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

the correct answer is d
