<p>18)Which of the following could explain the fact that a woman whose ovulation is normal maybe infertile?

Can mate and produce fertile offspring</p>

<p>21)An organism that has 6 jointed walking legs, an exoskeleton, and 2 antennae is classified as
An insect</p>

<p>22)Cyanobacteria (blue-green algae) lack which of the following?
mitochondria</p>

Snake OR lizard OR frog OR alligator OR turtle</p>

<p>24)Of the following, the best indicator of the rate of photosynthesis in green plants is the rate at which?
Carbon dioxide is consumed</p>

<p>25)Which of the following DOESN’T contain a membrane as part of its structure?
chromosome</p>

<p>26)Which of the following is a true statement about photosynthesis?
It is initiated by absorption of energy</p>

<p>27)If two parents are carriers of the same recessive allele and their first five children exhibit the dominant phenotype, the probability that their next child will exhibit the recessive phenotype?
1/4</p>

<p>28)True statements about linked genes include which of the following?
1-The alleles for linked genes may be separated due to crossing-over.
2-Linked genes are on the same chromosome
3-Linked genes occur only on the sex chromosome</p>

<p>29)The aerobic cellular respiration of glucose is different from the simple burning of glucose in that the aerobic respiration of glucose
Release more energy</p>

<p>30)Prokaryotes and eukaryotes are both similar in a lot except
mitochondria</p>

<p>31)The function of mitosis is to
Replicate chromosomes OR distribute one copy of each chromosome to each new cell</p>

<p>THANK YOU and Sorry for the disturbance.:);)</p>

<p>These are my comments and answers.</p>

<p>10) No inheritable change is produced by cutting off tails.
11) Reproduction is key in natural selection.
13) Genetic drift.
15) Yeast is a fungi.
16) Only mutations in gametes or gamete-producing cells can be inherited.
19) seeds>fleas>mouse>coyote>snake
24) NETT carbon dioxide consumption would be best, but if that's not in the option, carbon dioxide consumption would be fine.
28) 1 and 2.
30) There is not just 1 difference. There are many, in fact. Mitochondria is one of them. Size of the genome, arrangement of chromosomes, mitosis/binary fission, arrangement of genes are all different as well.
31) Distribute one copy of each chromosome to each new cell.</p>

<p>I'm unsure of 18, although it should be 1.
I'm unsure of 23, should be turtle, I believe.</p>

<p>All your other answers are accurate, IMHO. All the best for your Bio Subject Test; I just took mine in Dec. :)</p>

<p>I didn't take the Bio test but the one least closely related to the others for number 23 would be a frog, all the rest are reptiles.</p>

<p>Oh right, frogs it is. :)</p>

<p>Forgot that turtles were reptiles.</p>

<p>Thanx a lot, guys.</p>

<p>For #19 I'd say mice don't eat fleas
and fleas feed off of coyotes/dogs, etc</p>

<p>Now that you mentioned it, yes, that would be true. :)</p>
