A gas fills its container, taking both the shape and the volume of the container. Liquids and gases are called fluids because they can be made to flow, or move. In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.
Environmental barriers to physical activity include both external/physical factors and social factors that may make it harder or easier for you to exercise.
Answer:
variable expressivity; incomplete penetrance
Explanation:
In genetics, variable expressivity refers to the fact that individuals having the same alleles/genes/genotype associated with a particular genetic condition may exhibit different clinical features of this condition. In general, variable expressivity is due to the combination of both genetic and environmental factors. An example of variable expressivity is the Marfan syndrome, where all individuals with this disorder have a dominant mutation in the FBN1 (fibrillin 1) gene and show different degrees of the same phenotype. Moreover, incomplete penetrance (also known as reduced penetrance) refers to the complete absence of a genetic trait or disease in individuals having alleles/genes/genotype associated with the condition. In consequence, individuals with incomplete penetrance do not develop features of the disease. An example of incomplete penetrance is given by those individuals with mutations in BRCA1/BRCA2 genes (associated with an increased risk of developing breast cancer) that do not develop cancer.
Answer:
Option C: Each granddaughter cell is haploid (n)
Explanation:
A diploid cell is a cell that contains two full sets of chromosomes. Meiosis is a process whereby the the original diploid cell produces 4 cells. These cells contain half of the genetic information that the diploid cell that underwent division contained. These cells that contain half of the chromosome types are referred to as haploids. These haploids have just one complete set of chromosomes whereas the diploid (as the name suggests) has two full sets. Examples of haploids are the reproductive, or sperm, cells that humans have. So essentially, haploids are the reproductive cells that are produced by meiosis.
Now, meiosis divides the cell by 4 whereas, through mitosis however, each cell splits into two. These two cells that were produced are completely identical to each other which means that they have the same number of chromosomes and are, therefore, haploids themselves as well.
