Answer:
Genes are passed down to children by the process of meiosis. Meiosis includes gametes (sex cells). Most cells in our body are diploid, they have 23 pair of chromosomes (46 in total). 23 come from our father and 23 from our mother. The gametes are haploids, which mean that they only have one copy of each chromosome. The gametes are formed by meiosis, which leads to genes being passed onto children. Meiosis is where a normal diploid cell divides to make four non-identical haploid cell. First, each chromosome makes a copy of itself. The pairs of chromosomes line up and divide. The two new cell divide again creating 4 new daughter cells, each with a single set of chromosome. Each new sex cell has a combination of the genetic material from the mother and the father. Now when a sperm fertilises and egg, a new combination of chromosomes are created. This is a diploid cell, which then divides to create a zygote (baby). The baby now has the genes (genetic material) from the parents.

Penjelasan:
Dengan 28 pekerja, pekerjaan akan selesai dalam 24 hari
Jika pekerjaan akan selesai dalam 16 hari, jumlah pekerja yang dibutuhkan = x
Asumsikan semua pekerja bekerja pada tingkat yang sama:
Tarif per pekerja:
28 pekerja = 24 hari
1 pekerja = 28 * 24
1 pekerja = 672 hari
Untuk menyelesaikan pekerjaan dalam 16 hari:
672 hari / 16 hari
= 42 pekerja
Pekerja tambahan dibutuhkan:
42 pekerja - 28 pekerja
= 14 pekerja
Oleh karena itu, dibutuhkan 14 pekerja tambahan
