Answer;
He conducted an experiment with breeding pigeons.
Explanation;
The pigeons provided the perfect animal to test his theory of selection for quite a number of reasons including its trait diversity from wing structures to color patterns to size to flight patterns. From these experiments he concluded that by natural selection of randomly occurring traits that make species better suited for survival and reproduction, evolve in the astounding diversity of organisms on Earth today.
Correct answer: D). Algal cells have a cell wall made of chitin, while plant cell walls are made of cellulose.
Algae and plants are similar as both of them produce their own food by the process of photosynthesis. The main difference is found in their complexity.
The cell wall of the plants is made of cellulose, hemicellulose and pectin, and polysaccharides, while the cell wall of algae is made up of chitin, which is a polysaccharide derived from glucose.
When a cell undergoes meiosis,the outcome of the process is FOUR HAPLOID CELLS.
Meiosis refers to a form of cell division which always results in the formation of four daughter cells. The four daughters cells produce have diploid cells which contains half the original of chromosomes from the parents. A diploid cell has two of each chromosome, one from each parent. The eggs and the sperms that are involved in reproduction possess haploid cells. In meiosis, the whole process start with diploid cells which divide twice to produce four haploid cells.
