a cell type that has half the alleles of a somatic cell - haploid a condensed form of DNA and proteins that can be seen during mitosis and meiosis; each one contains several genetic loci - chromosomes a condensed form of DNA and proteins that can be seen during mitosis and meiosis. These contain the genes. - Chromosomes A diploid cell becomes two haploid cells during which phase? - meiosis I a disease inherited on a dominant allele that results in progressive deterioration of the nervous system - Huntington's disease a distribution of variation in a trait, such as height, that does not have any clear cut boundaries between types - continuous A normal human cell containing 22 autosomes and a Y chromosome is - a sperm cell. A well stated ___ allows a researcher to make a/an ____ which can then be tested. - Hypothesis/Prediction All chemical reactions in the human body that include build up or breakdown of macromolecules are termed ____________. - metabolic reactions. All of the red squirrels living on a college campus would be a(n) - Population all the genetic material of an individual - genomeAlternate forms of a gene are called - alleles An example of a genotype is - homozygous dominant An organic compound always contains one or more atoms of ____________. - Carbon Animal fats are usually solid at room temperature because their fatty acids are ___. - Saturated Assure that the sampled group represents the population as a whole - Using groups as large as possible Atoms are "happy" and thus most stable when - The outer electron shell is full The number of protons and electrons are equal building of communities without long-term degradation of environment - sustainable development Cancer cells divide in an unregulated fashion (in other words, even when they are not supposed to divide). They are able to do this because they ___ - progress through the cell cycle without proper regulation Celebrities Jenny McCarthy and Jim Carrey are big proponents of anti-vaccination claiming that it causes autism in children. Their testimonial in news media is a classic example of ___________. - Anecdotal evidence. Chemistry is the study of ____ and energy. - Matter crossing over and independent assortment occur - MeiosisDamage to a DNA molecule which changes the sequence of that molecule is known as a - mutation DNA contains a sequence of nucleotides that are the coding information for the synthesis of - proteins during meiosis, the alleles of a homologous pair separate into different daughter cells - law of segregation Each of the following is a feature of all known living things EXCEPT - Genes made from proteins Eliminate as many alternative hypotheses as possible - Using both a treatment and a control group Eliminate the possibility of bias - "Blinding" both the researcher and the participants Homologous chromosomes - are found in pairs in body cells but not in gametes. almost always contain identical alleles. In humans, the ability to roll the tongue is a dominant trait; the inability to roll the tongue is a recessive trait. If an individual homozygous dominant for this trait has a child with an individual who cannot roll his tongue, what is the chance that the child will have a heterozygous genotype? - 100% In humans, the sex of the offspring is ordinarily determined by the - Sex chromosome carried by the sperm cell In polygenic inheritance, - multiple alleles and genes contribute to a phenotype. In the classification of living organisms, what level of organization is the group called Archaea? - DomainIn which organelle is the majority of ATP molecules synthesized? - mitochondria indicates the number of chromosomes in a somatic cell - diploid List the two cells types - prokaryotes and eukaryotes
