1. a geneticist is studying the karyotype of a person with a normal number of chromosomes. which of the
following would be the correct chromosome configuration?
a. 22 pairs of autosomes and one pair of sex chromosomes
b. 22 autosomes and 1 sex chromosome
c. 22 pairs of alleles and one pair of sex chromosomes
d. 46 pairs of autosomes and one pair of sex chromosomes
e. 46 pairs of alleles and one pair of sex chromosomes

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

it is stable as it is in group 0 which have full outer shells of electrons

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
