Answer;
Alleles are passed from the parents’ sex chromosomes to the sex chromosomes in the offspring.
Explanation;
-Sex linked traits are traits that are carried by the sex chromosomes and inherited together.
-Gene exists in alternative forms called alleles and each allele for a trait is inherited from each parent.
-Sex traits, like the other traits, are passed from parents to off spring through the process of sexual reproduction.
1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun
1AU=<span>149597870.7 kiometers
1 billion=1,000,000,000
600 billion=600,000,000,000
</span>
<span>x times 1AU=600,000,000,000
x times </span>149597870.7=<span>600,000,000,000
solve for x
divide both sides by </span><span>149597870.7
</span>x=4010.75
so aprox 4011 AU's

Explanation:
The fundamental microscopic components of all species are cells. Two groups of cells, Prokaryotes and Eukaryotes, exist. Prokaryotic (meaning pro: before and Karyon: for kernel/nut) identifies species that <em><u>do not have membranes surrounded by a cell nucleus or other organelles</u></em>.
Bacteria, thought to have evolved 3.5 billion years ago are types of prokaryotes and are the oldest forms of life on earth. As single- celled life forms, they take on various shapes (rods, cones, spheres, spirals) and are capable of reproduction through asexual binary fission, and exchange genes in horizontal gene transfer (conjugation, transduction etc) and cell fusion .
They live in communities and, grow exponentially in number over short periods of time. Some are autotrophs, capable of producing their own food through photosynthesis. Some species can move around using flagella, long whip-like projections from the cell.
In humans, bacteria have colonized the intestinal tract. While some are beneficial as part of the microbiome, others are disease-causing pathogens- these are typically eliminated via the use of antibiotics.
