question:
Passage: Mixtures have different properties depending on the size of their particles. Three types of mixtures based on particle size are solutions, suspensions, and colloids, all of which are described in Table below . You can watch videos about the three types of mixtures at these URLs:. Answer: solutions, suspensions, colloids
answer:
What are the three types of mixtures?

Passage: Improving crops by selecting for certain genetic traits. The desired traits promote productivity. Recently, genetically engineered crops have been introduced. Answer: promotes productivity
answer:
What is the advantage of selecting for certain genetic traits for crops?

question:
Passage: 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. Answer: karyogram
answer:
The number, size, shape, and banding pattern of chromosomes make them easily identifiable in a what?
