B. is your correct answer.
Answer:
Scientists first discovered chromosomes in the nineteenth century, when they were gazing at cells through light microscopes. But how did they figure out what chromosomes do? And how did they link chromosomes — and the specific genes within them — to the concept of inheritance? After a long period of observational studies through microscopes, several experiments with fruit flies provided the first evidence.
Explanation:
Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene.
I think 1 should represent condensation and 2 should represent precipitation.
High level items in a wbs are broken down or decompose into smaller tasks.
Work breakdown structure (WBS) is a chart that describes everything a project needs to achieve. Work breakdown structure is easy to understand as it organizes and breaks down complex activities into smaller levels. Each level of the work breakdown structure provides additional definition and information about the project.
