Question

the fertilization of female egg cell with a male sperm cell; strings of dna in cell nuclei; the genetic material that determines the nature of life forms; the code for a particular characteristic of a living organism; conception; uterus; zygote; gene; fertilize; chromosomes; deoxyribonucleic acid

Explanation:

• For the first phrase, the fertilization process of egg and sperm is related to conception (the act of fertilization leading to the start of pregnancy).
• Chromosomes are defined as the thread - like structures (strings) of DNA present in cell nuclei.
• Deoxyribonucleic acid (DNA) is the genetic material that dictates the nature and traits of life forms.
• A gene is a segment of DNA that codes for a specific characteristic (trait) of a living organism.

Answer:

1. "the fertilization of female egg cell with a male sperm cell" connects to "conception" (or "fertilize" can also relate, but "conception" is the process here).
2. "strings of DNA in cell nuclei" connects to "chromosomes".
3. "the genetic material that determines the nature of life forms" connects to "deoxyribonucleic acid" (DNA).
4. "the code for a particular characteristic of a living organism" connects to "gene".
