For percentage increase I got 342% or something then I changed it because I didn't think it could go past 100% so I swapped the two numbers I divided by and then x100 to get a different answer :/
Because I did: (144/42) x100 = 342% or something like that Then I thought that was absurd so I did: (42/144) x100 = 29.16%
I am so confused I didn't know percentages could go above 100% for percentage increase!!
Question 1 a) Centromere b) joins to spindle fibers in metaphase and pulled apart in anaphase c) different alleles d) chromosomes not replicated into sister chromatids as figure 2 is prior to synthesis. e) 3 chromosomes- 1 from each homologous pair( ie. one long,1 medium and one short) f)crossing over
Question 2 a)similar organisms capable of breeding to produce fertile offspring b)6.9 something c)destruction of plants and growing of 1 dominating crop means less food sources, habitats for insects and use of pesticides
Question 3 a) groups within larger groups with no overlap b) groups based on evolutionary relationships c) animal A because least difference in amino acid sequence therefore DNA similar as DNA codes for amino acids d)same number of differences however may code for different amino acids f)hemoglobin not found in all organisms while respiration occurs in all
someone else continue
for 3C I wrote it was beacuse you arent directly comparing Animal B and C so you cant really tell how similar they are.
Oh sh!!!t.how stupid .for the Amish question I wrote down 1250x200 For the answer i got 2500000.where did I got 5 zeros from I don't nbdhlngrilnsfk know.FML
ill start: Question 1 a) Centromer b) joins to spindle fibers in metaphase c) different alleles d) chromosomes not replicated into sister chromatids as figure 2 is prior to synthesis. e) 3 chromosomes- 1 from each homologus pair( ie. one long,1 medium and one short)
Question 2 a)similar organisms capable of breeding to produce fertile offspring b) groups withing larger groups with no overlap c) groups based on evolutionary relationships d)cant remember
some one please quote me and continue...
All my answers match with urs except for part 1d I out the chromosomes are in meiosis 2 while the first figure they're on meiosis 1 is that right ? 😢
what did everyone get for the percentage increase and the Amish population?
I got 342% and 250,000
i got 442% or something.
in the snakes i'm pretty sure 1 question was about how the male shows less courtship behaviour to shorter females and filter paper with shorter lipids on them. (the bar chart)
the one after was trying to make you state the relationship between the longer females producing more fatty acids which initiates courtship behaviour.
why the garter snakes don't react to other female species who also produce fatty acids on their skin was to due to the fact they have different fatty acids? (got this one wrong i think now, i should've said about how courtship behaviour is specific to species etc.)
also i said you could intrapolate the line of best fit to find values to estimate the courtship behaviour towards females of 75cm or something.
btw for phylogeny i said something along the lines of: 'share a common ancestor' is that a mark? =(
well the exam started out ridiculous for me because i caved to exam pressures and made a stupid error like thinking the exam would be over 30 minutes early. so i rushed straight to the end. grrr.
