Genus -->Two organisms that are classified in the same family would not necessarily be classified in the same? (KPCOFGS) Kingdom Phylun Class Order Family Genus Species Produce antibodies that can clump bacteria or viruses together so that macrophages can ingest them. -->Plasma B cells are essential in the human immune response because of their ability to? Breathe through moist skin and walk on four limbs -->The first vertebrae to live on land were the amphibians, characterized by their ability to? These lands were once next to each other and have since drifted apart. -->Fossils of ancient reptile called Lystrosaurus have been found in Africa, India, and Antarctica. Which of the following best explains this distribution? Alleles -->Gregor Mendel identified "factors" that could be passed down from parents to offspring and that resulted in the expression of certain characteristics. Today we call Mendel's factors? A decrease in the output of the Calvin cycle -->A decrease in the amount of carbon dioxide present in the air surrounding most plants would most likely result in? Oviduct -->Fertilization of a human ovum normally occurs in the? GCAUCA DNA (A=T G=C) base pairs RNA (A=U G=C) -->A DNA strand has a base sequence of CGTAGT the mRNA strand transcribed from this DNA is? They do not produce enough insuline to absorb sugar from the bloodstream -- >Diabetics may have sugar in their urine because? Diarrhea -->Damage to the cells lining the large intestine would likely result in?? Mitochondrion -->The area of this cell in which a chemiosmotic hydrogenbion gradient is used to produce ATP or energy is ? Under bright white light -->Experments involving the reduction of the blue dye DPIP which loses its blue color and becomes clear as it absorbs electrons have shown that the dye shows the greatest loss of color when in the presence of chloropast? As a bicarbonate ion -->In humans carbon dioxide in the bloodstream is mainly transported from cells to lungs? Bacterium -->A newly discovered organism has ribosomes that can be inhibited by tge antibiotic Streptomycin as well as free fliating DNA not enclosed within a nuclear membrane. This organism is moat likely a? Centrioles -->In or around the cells of flowering plants one woukd expect to find all of the following EXCEPT? Transitional fossils such ad Archaeopteryx have been discovered. -->The best current evidence that modern day birds evolved from certain lineages of dinosaurs or other repiles may be supplied by the fact that? A rapid decrease in the ability of the axon to conduct an action potential -- >Malfunctioning sodium (Na+) potassium (K+) pumps along a neurons axon would likely result in? Follicle simulating hormone ..regulates sperm production -->Which of the following hormones is correctly linked to its function in mammals? Digestion -->The process of breaking food particles into the macromolecules that make them up is called? Chloroplast -->In a plant cell the reactions of photosynthesis take place within the? Specialized vascular tissues -->Mosses can not grow very tall due to their lack of? Parasitism -->Two plants (A and B) of different species are growing together in the same pot. When plant A is removed and grown in a separate pot, it rapidly grows much taller than it had been before, while plant B dies. Which term describes the type of relationship that plants A and B most likely had? Rr...red -->Red plants (R) are dominant to green plants (r). Crossing homozygous (RR) red plants with homozygous (rr) green plants would result in which of the following phenotype/ genotype combinations? Antibodies -->Proteins that bind to the surfaces of pathogens and help to destroy the pathogens are known as? Mammary glands -->Mammals share all of the following characteristics with other vertabrates EXCEPT?
