<p>okay that makes sense
is it possible that the question didnt mean sea to land at all?
because it said - what was necessary for vertebrates colonization of early terrestrial environments
could that mean new environments after they were already land dwellers?</p>
<p>I put that it will compensate the homeostasis…because the defective gene will make it unable for the body to achieve a balance…</p>
<p>swedishm8,
I think the question asked for which of the statements was not supported by the expirment. I put that the one that said the light directly germinated the seed, which is not true becuase seeds need water to germinate, not direct light</p>
<p>Yeah ur right Jay, sorry I forgot to include that.
But I also picked the last choice with direct light</p>
<p>Yeah, I also picked direct light. Seed germination is definitely not caused by light, it’s caused by plant hormones.</p>
<p>I said homeostasis is compromised (aka weakened) b/c of the defective enzyme.</p>
<p>with the muscle/nerve diagram/questions is the only part that moves are the nurons directly attached to the part that is being touched or contracted or does all of the nuerons/musvles move?</p>
<p>Hang on, the germination light one was in the E section? or in the general test?</p>
<p>alright looks like i got that digestive enzyme one wrong (i put another gene would code for the correct one), was the answer for the sexual reproduction one a zygote made from mitosis? all the other answers didn’t look right</p>
<p>a zygote is made from fertilization, not mitosis so the answer was that sexual reporduction need haploid gametes</p>
<p>Lauren926, wow I feel SO AWFUL for that girl! I cannot even imagine…</p>
<p>Here’s the updated list! :)</p>
<p>-water separation: lipids
-insulin (secretory granule)
-graph supported the route the radioactive substances traced
-graph showed how it goes from rer to golgi to vesicles
-right atrium, right ventricle, lungs, left atrium, left ventricle, aorta
-most diversity: island A
-least extinction: island A
-least immigration: island C
-two germ layers: hydra and jellyfish (II and IV)
-scar on tree: .9
-ribose, phosphate, nitrogenous base: nucleotide
-polygenic tree: dietary needs
-earthworm diagram: the three involved in segment I, the three involved in segment II, stimuli from segment III would not cause muscle contraction in segment I
-controls: temp and light (definitely only two variables!)
-lymph: interstitial fluid
-dialysis experiment, it was NOT isotonic, osmosis could have been incomplete at end of 24 hrs so answer was I only (water diffused from outside to inside)
-blastocyst in uterus
-fertilization in oviduct
-gametogenesis in the testes/epididymis
-necessary for sexual rep: two haploid (no centrioles in plants)
-allele: related proteins
-the one with the “what made it necessary to move onto land” answer choice was A.*(this included lungs, although am not sure what the other two were) - kidneys, amniotic sac
-New nucleotide = no mutations
-Genotype affects survival = no natural selection
-Selective reproduction based on phenotype = no random mating
-Heterozygous for 3 genes = 8 gamete possibilities
-some bacteria were already resistant (organisms CAN’T evolve)
-Endotherms are regulated by metabolic heat
-Control for the bacteria = piece of paper w/ no antibiotic
-Concentration of bacteria was 10x higher at the end (one order of magnitude)
-Huntington’s = 50%
-amino acid sequence: deletion
-above would cause: one less amino acid
-cell membrane- all organisms
-ribosomes: all organisms
-cellulose cell walls: all plants
-green/yellow punnett square: 25%
-colonizing species: lichens
-they caused: environment to become more suitable for the pioneer species
-succession diagram: deciduous forest
-pH of blood: 7.5
-k+ on stomates: cause cell to shrink
-enzyme mutation: homeostasis would be compromised?
-corn, which does not affect: low light</p>
<p>but in plants you don’t need haploid gametes, there are polyploid gametes. also i’m not sure if it said zygote made from mitosis, it might have said zygote that has went through mitosis</p>
<p>No I’m pretty sure it said zygote made from mitosis, which isn’t correct b/c a zygote is a fertilized cell, and it hasn’t undergone any cell division yet. It’s just been fertilized. </p>
<p>Hang on lollypop, I thought for the K+ on stomates, it makes the cells bigger. K+ in guard cells would cause osmosis of water to go into the cell too.</p>
<p>well haploid gametes certainly isn’t right because there are polyploid gametes in plants</p>
<p>plants do need haploid gametes. they also have sperm which is located in the pollen and it also has an egg located in the ovary. the pollen travels through the air and gets collected by the stigma of the female part and then shortly after a zygote is producted.</p>
<p>
</p>
<p>Is this definitely right? I put it but wasn’t sure.</p>
<p>do you guys know when the deadline for canceling scores are</p>
<p>yes i realize that but there exists polyploid plants that reproduce through the fusion of diploid gametes so haploid gametes aren’t required
[Polyploid</a> - Wikipedia, the free encyclopedia](<a href=“Polyploidy - Wikipedia”>Polyploidy - Wikipedia)</p>
<p>No thats wrong.
If there’s K+ going to stomates, it makes it more hyper**** which makes it less water, so more water goes in. Therefore the cell becomes turgid and opens rather than shrinks.</p>
<p>@ infrapr0ds.</p>
<p>It’s definitely haploid gametes. In eggs male gametophytes produce sperm in antheridia and females produce eggs in archegonium. The two haploid fuse to produce a diploid sporophyte. </p>
<p>The existence of polyploid plants is due to nondisjunction, which is an anomaly.</p>
