An ionic bond is a metal and nonmetal combined so the answer would be K and Br
Answer:
The correct option is A. Measuring radioactive decay of element isotopes
Explanation:
At the time of formation of rock, certain kinds of radioactive isotope elements get trapped in the rock. These radioactive isotopes are unstable and decay over a period of time forming daughter elements. A rock which will have more number of radioactive elements will be newer to a rock containing non-radioactive daughter elements.
The radioactive decay of each element can be measured by the half-life of elements. This is the primary technique to determine the absolute age of a rock.
Answer:
The parents would have brown eyes.
Explanation:
Given Bb x Bb, this tells you that both parents have brown eyes and are carriers for a reccessive trait (blue eyes). Remember that the uppercase letters are considered dominant and the lower case letters are considered recessive. In order for the blue eye allele to show, you would need to have the genotype: bb.
There is 2 sets of chromosomes in a regular/somatic cell. In this case chimpanzee have 48 total in each regular cell which means their sex cells/haploid cells have half of that which would be 12 chromosomes. (Haploid cells only have one set of chromosomes)
Answer:

Diffusion is a substance movement from a region of high concentration to low concentration
