Q: Q: A complementary pair of chromosomes have genes for the same characteristics in the same location on the chromosome are known as? Read this paragraph and choose the correct option from the provided answers: From Genotype to Phenotype Each human body cell has a full complement of DNA stored in 23 pairs of chromosomes. Figure 28.24 shows the pairs in a systematic arrangement called a karyotype. Among these is one pair of chromosomes, called the sex chromosomes, that determines the sex of the individual (XX in females, XY in males). The remaining 22 chromosome pairs are called autosomal chromosomes. Each of these chromosomes carries hundreds or even thousands of genes, each of which codes for the assembly of a particular proteinthat is, genes are "expressed" as proteins. An individual's complete genetic makeup is referred to as his or her genotype. The characteristics that the genes express, whether they are physical, behavioral, or biochemical, are a person's phenotype. You inherit one chromosome in each paira full complement of 23from each parent. This occurs when the sperm and oocyte combine at the moment of your conception. Homologous chromosomesthose that make up a complementary pairhave genes for the same characteristics in the same location on the chromosome. Because one copy of a gene, an allele, is inherited from each parent, the alleles in these complementary pairs may vary. Take for example an allele that encodes for dimples. A child may inherit the allele encoding for dimples on the chromosome from the father and the allele that encodes for smooth skin (no dimples) on the chromosome from the mother. Choices: - analogous chromosomes - endroctyne chromosomes - symbiotic chromosomes - homologous chromosomes A:
A: homologous chromosomes

Q: Q: What do we call animals that have a backbone and belong to the phylum chordata? Read this paragraph and choose the correct option from the provided answers: Vertebrates are animals that have a backbone. All of them are placed in the Phylum Chordata. Modern vertebrates include fish, amphibians, reptiles, birds, and mammals. Only about 5 percent of animal species are vertebrates. Choices: - organelles - mammals - invertebrates - vertebrates A:
A: vertebrates

Q: Q: Which state of matter has the lowest density? Read this paragraph and choose the correct option from the provided answers: Gases have much lower densities than liquids and solids. For example, liquid water is over 1000 times more dense than water vapor at STP. Choices: - liquids - fluids - solids - gases A:
A: gases

Q: Q: Along with muscles, what helps the body move with relatively little force? Read this paragraph and choose the correct option from the provided answers: With the help of muscles, joints allow the body to move with relatively little force. Choices: - glands - limbs - nerves - joints A:
A: joints
