This means that her son is small compared to other 6 month old children.
A percentile is a measure between 0 and 100 that compares children of similar age in order to know if a particular child is growing well. The higher the percentile number, the bigger the child is compared to other children of same age. If a child is in the 50th percentile for height, it means the child is in the middle of the pack.
Connell's famous barnacle experiment was initiated to learn more about competitive exclusion and distribution of branacle species. Barnacle species are distributed in distinct zones on the rocky shores of the Atlantic coast. The Chthamalus in upper intertidal zone; is a smaller species and the semibalanus in low intertidal zone which is a larger species. Chthamalus found in the higher physical stress and higher temperatures because the low tide levels causes them to be exposed to the extreme outside environment for longer periods of time than the semibalanus. Additionally barnacles can only feed while submerged and the higher up shore a barnacle is, the less it can feed and grow. The experiment wanted to understand why they lived this way.
Before mitosis can begin, the DNA within the parent cells must be duplicated so that each daughter cell receives the exact same genetic information. For this reason, cells produced during mitosis are identical. <span />
Answer: B). fertilization, diploid
Explanation: During fertilization, the sperm cell (a gamete) fuses with an ovum or egg (a gamete) to form a zygote. Each of the gametes have haploid number of chromosomes (23 chromosomes) and they fuse to produce a zygote with a diploid number (46 i.e., 23 pairs) of chromosomes.
