Answer:
c. bivalents.
Explanation:
In Meiosis a bivalents are formed during the first stage of meiosis which is the prophase. The bivalent consist of a paired chromosome and four chromatids i.e two chromosomes in a tetrad. one chromosome comes from each parent.
In mitosis, a bivalent is not formed. There is the presence of chromatids, homologs, centromeres and spindles during mitosis and meiosis.

Answer:
c. Living things are made of the same basic building blocks and use them in the same way.
Explanation:
Living things are made up of a genetic material called DNA, which is a type of nucleic acid. This DNA stores the genetic information needed by the cell to produce useful products (proteins). However, nucleic acids are made up of building blocks called NUCLEOTIDES that makes up the genetic code.
One unique characteristics of this genetic code is that it is NEARLY UNIVERSAL i.e. it is same in all living things and used the same way. Hence, according to this question, Wheat germ DNA is similar to cheek cell DNA and bacterial DNA because living things are made of the same basic building blocks and use them in the same way.
-Genetically modified crops :weather and disease resistant meaning more crops and more food available ensuring food security for many counties
- Vaccinations : immunisation from diseases that previously proved deadly
- Fertility assistance ,prenatal scanning, home pregnancy tests
-research into Alzheimer’s
- provided cancer and heart disease treatment
- enabled growing of organs so waiting lists for transplants get shorter and more lives are saved
