There are cases in which a person inherits a very high susceptibility to cancer. A woman who is heterozygous for a mutation in the BRCA1 gene has one functional allele that helps to suppress tumor formation and one nonfunctional allele of the same gene
She has a 50-70% chance of developing breast cancer before age 70. A tumor is likely to form when a cell "loses heterozygosity" at the BRCA1 gene. This will happen if: A. germ cells in the affected individual develop a mutation in the remaining functional allele of BRCA1. B. a somatic mutation in a breast cell inactivates the remaining functional BRCA1 allele. C. a silent mutation occurs in the remaining functional BRCA1 allele.
Type III survivorship curves reflect ____
a. high juvenile mortality b. low juvenile mortality c. high survivorship d. relatively constant mortality e. high adult mortality
A team of researchers is studying the external structures on the dorsal (back) surface of a spider mite. The spider mite seems to be the habitat of an even smaller mite, which is approximately 0.05 mm. While they can see the dorsal surface of the spider mite with their naked eye, they cannot see the mite clearly. The researchers are writing a grant to provide support for a microscope to use to study these new mites. They need to purchase a microscope with a high magnification to observe the new mites on their habitat. It is not necessary for them to observe living mites. Based on the information given, what type of microscope would you suggest?
A. dissecting microscope B. scanning electron microscope C. binocular compound light microscope D. transmission electron microscope
