Elements differ from one another by their number of - Protons A solution with a pH is - strongly basic How many fatty acids are bonded to a glycerol molecule to produce a lipid ( a triglyceride) - 3 Neucleotides - can be linked together to form a double helix contain phosphate groups contain sugar molecules contain nitrogenous bases Which of the following is the most basic level of chemical organization? - Atoms What is not a lipid? - cellulose Which of the following is an ...

A population is - All the individuals of a particular species within a given area at one point in time Based on past rates of birth and death you set up a logistic model of a dolphin population. This model predicts that there will be 10,020 dolphins next spring. How should you interpret this model's prediction? - There will probably be about 10,000 dolphins next spring, but many outside factors might cause the population to increase or decrease unexpectedly. At a certain population size c...

1. ABO blood typing is an example of a. Multiple alleles b. Codominance c. Incomplete dominance d. Polygenic inheritance e. 2 of the choices - a. Multiple alleles b. Codominance 2. A plant with red flowers is crossed with a plant with white flowers. The resulting offspring have pink flowers. These pinks flowers can be crossed with themselves to produce red flowers, white flowers, and more pink flowers. What term describes the dominance of this trait? a. Recessiveness b. Dominance c. ...

Characteristics of true fungi - 1) eukaryotic 2) complex multicelluar 3) heterotrophic by absorbtion 4) cell walls are composed of chitin 5) adults are haploid and exhibit Haploid sexual life cycle 6) fungi reproduce very well asexually (mitosis) ->spores 7) no motile stage in their life cycles 8) composed of hyphae 9) hyphae typically form interwoven mass called a mycelium Chitin - complex nitrogen polyscachanide Haploid sexual life cycle - fusion of gametes, produces a z...
