Q: Electromagnetic waves vary in wavelength and in what property, which is lower in waves of longer wavelengths? Read this paragraph and choose the correct option from the provided answers: Electromagnetic waves vary in wavelength and frequency. Longer wavelength electromagnetic waves have lower frequencies, and shorter wavelength waves have higher frequencies. Higher frequency waves have more energy. Choices: - size - density - resonance - frequency A:
**Answer**
frequency

Q: The number, size, shape, and banding pattern of chromosomes make them easily identifiable in a what? Read this paragraph and choose the correct option from the provided answers: 13.2 Chromosomal Basis of Inherited Disorders The number, size, shape, and banding pattern of chromosomes make them easily identifiable in a karyogram and allows for the assessment of many chromosomal abnormalities. Disorders in chromosome number, or aneuploidies, are typically lethal to the embryo, although a few trisomic genotypes are viable. Because of X inactivation, aberrations in sex chromosomes typically have milder phenotypic effects. Aneuploidies also include instances in which segments of a chromosome are duplicated or deleted. Chromosome structures may also be rearranged, for example by inversion or translocation. Both of these aberrations can result in problematic phenotypic effects. Because they force chromosomes to assume unnatural topologies during meiosis, inversions and translocations are often associated with reduced fertility because of the likelihood of nondisjunction. Choices: - xerophyte - spirogyra - nanocyte - karyogram A:
**Answer**
karyogram
