~SAT 2 Biology Review Thread~

<p>okay ill ask a question: </p>

<p>name an autosomal dominant disorder</p>

<p>Yeah, it should be convergent.</p>

<p>What is Mendel’s theory of segregation ?</p>

<p>Huntington’s Disease.</p>

<p>Alleles will separate during gamete formation.</p>

<p>Which enzyme proofreads DNA during replication?</p>

<p>DNA polymerase</p>

<p>If you are located at an environment that is at 5 degrees south and is at the top of a mountain at an elevation of 2,000 ft which biome will it most likely resemble
a)tropical rain forest
b)taiga
c)tundra
d)desert
e)deciduous forest</p>

<p>b taiga. 10 char</p>

<p>Shouldn’t the tundra be at the top of the mountain? =o </p>

<p>What is the name of the hormone that induces salt reabsorption in the kidney, and where in the nephron does it have its effect?</p>

<p>ADH, antidiuretic hormone…</p>

<p>Where is deoxygenated blood and oxygenated blood?</p>

<p>ADH presents in the collecting tube right ?</p>

<p>Oxygenated blood are basically in arteries (except the pulmonary artery) and the left side of the heart. Deoxygenated blood are in veins (except pulmonary vein) and the right side of the heart.</p>

<p>What is a cellular and an acellular slime mold ??</p>

<p>Oxygenated blood is only in the pulmonary vein.
Deoxygenated blood is only in the pulmonary artery.</p>

<p>No idea.</p>

<p>Whoa lol! ADH is for water reabsorption, and Aldosterone is for salt reabsorption! And it takes effect in the distal convoluted tubule lol. (thats from PR)</p>

<p>Cellular and acellular (or plasmodial) slime molds are both fungus-like protists. Cellular is a bunch of different cells that aggregate together (at the signal of cAMP i think) and Acellular/Plasmodial is one big cell with a bunch of nuclei</p>

<p>Weird… I’m going to go look that up now.</p>

<p>What is oxytocin?</p>

<p>A hormone produced by posterior pituitary which helps generate smooth muscle contraction such as in child labor. It has positive feedback mechanism instead of normal negative feedback mechanism.</p>

<p>What are 3 phyla of plant-like protists and 4 phyla of animal-like protists ?</p>

<p>Plantlike: Green algae, red algae, brown algae [lol i used the ez names]</p>

<p>Animal like: Apicomplexans(Sporozoans), Ciliates, Amoebas…idr anymore lol</p>

<p>Where would a maple tree be found?
A. Tundra
B. Taiga
C. Tropical Rainforest
D. Temperate Deciduous Forest
E. Coral Reef (lolz)</p>

<p>Temperate deciduous forest</p>

<p>What vein carries oxygen rich blood?</p>

<p>im guessing ur looking for arteries? but whether it is classified as an artery or vein depends on the direction of the flow of blood.</p>

<p>what are the three components of urine and what are they the result of the breakdown of?</p>

<p>Pulmonary vein.</p>

<p>I’m guessing on this one: Nitrogen, Salt, Water. Result of filtration. Breakdown of… ??</p>

<p>^^ ahh understood about the pulmonary vein</p>

<p>components of urine are:</p>

<p>Urea- from breakdown of amino acids
Uric acid- from breakdown of nucleic acids
Creatinine- from muscle metabolism</p>
