Answer:
Why? I don't know ask the school why they're placed like that.
The formation of limestone takes place in shallow warm marine waters. Limestone forms from the collection of waste like shells, fecal matter, coral, and algal—so tropical marine animals. Since limestone is a sedimentary rock formed from tropical marine animal's leftovers, limestone deposits can tell scientists that the environment in which they evolved from was a tropical one.
The answer is; hydrophilic heads; hydrophobic tails
The hydrophilic heads of a phospholipid are composed of a phosphate and glycerol molecule. Since the phosphate has a charge, the head are able to interact with water molecules through hydrogen bonds (Remember water is a polar molecule). The hydrophobic tails are composed of hydrocarbon chains that are uncharged hence do not interact with water. When phospholipids are immersed in water, they form a bilipid layer - with the hydrophobic tails clumped up together in the center and the hydrophilic heads on the outside.
Answer:
The correct answer will be mitosis.
Explanation:
The life cycle of a plant is divided into two phases- diploid sporophyte and haploid gametophyte.
The gametophyte produces haploid gametes through a process of cell division which can produce daughter cells with the same genetic material without changing the ploidy that haploid cells will produce haploid cells. The equational type of cell division is known "mitosis" which produces cells with the same ploidy.
Hence, gametophyte (haploid) → gametes (haploid) through mitosis and thus option mitosis is the correct answer.
