Questions All Solved Correctly 2026
Updated.
From the cellular respiration and fermentation lab, why are the yeasts breaking down the
sugars? - Answer the yeast are breaking down the sugars to produce ATP
why will yeast metabolize monosaccharaides at a faster rate than disaccharides - Answer
yeast will metabolize monosaccharides faster than disaccharide’s because disaccharides are
more complex sugars and must first be broken down into its monosaccharide subunits,
therefore taking more time
how many NET molecules of ATP are created during aerobic respiration - Answer 36 ATP
What sugar releases the most CO2/min - Answer fructose
whats the difference between aerobic and anaerobic respiration processes - Answer aerobic
respiration utilizes oxygen while anaerobic respiration does not
in which phase of mitosis do two daughter nuclei form - Answer telophase
in which phase of mitosis does the cell replicate its DNA - Answer anaphase
in which phase of mitosis do replicated chromosomes align on an imaginary plane in the middle
of the cell - Answer metaphase
in what phase of the cell cycle does a cell spend most of its life - Answer interphase
why would an organism use mitosis for cellular reproduction - Answer when there is injury to
the individual, growth and development, asexual reproduction
what is the main difference between an animal cell and a plant cell going through cytokinesis -
Answer an animal cell forms a cleavage furrow while a plant cell forms a cell plate
what is the correct sequence of mitosis - Answer prophase, metaphase, anaphase, telophase
does this cell have chromatin or chromosomes in prophase - Answer chromosomes
, in which phase of mitosis does the nucleolus disappear and the mitotic spindle begin to form -
Answer prophase
two parents have the genotypes hh and Hh what portion of their offspring may have
Huntington's disease - Answer 2/4 have it
2/4 does not have it
offspring of two parents have type A, type B, and type AB, and type O blood what must be the
genotypes of the parents - Answer IA/IO and IB/IO
an individual has the genotype Xd/Y. what is the individuals gamete proportions? - Answer
2/4 Xd
2/4 Y
what is the pheonotype Rrl pink flower - Answer pink flower
is this individual a male or female XX - Answer female (XX)
chromosomes other than the X and Y are called - Answer Autosomal chromosomes
in this karyotype of an individual, which of the chromosomes have heterozygous alleles -
Answer chromosome 4- Hh
chromosome 9- I^A I^B
chromosome 19- L+ L-
chromosome 23- X^G X^g
when do the homologous chromosomes separate during meiosis - Answer in meiosis 1
when do sister chromatids separate during meiosis - Answer in meiosis 2
what is the difference between a heterozygote and a homozygote - Answer a heterozygote is
an individual having two different alleles (Hh) and a homozygote is an individual having two
copies of the same alleles (HH,hh)
lactic acid fermentation - Answer -anaerobic respiration
-muscle cells can utilize this pathway
