Answer:
Explanation:
It typically involves sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm. These are specialized reproductive cells called gametes, created in a process called meiosis.
The answers are as follows:
1. A
Cell is the basic unit of life. For a thing to be considered as a living thing it must possess at least a cell. The cell is the is basic unit of a living organism and all the biochemical activities that the cell need to maintain live is carried out inside the cell. On the contrary, non living things do not possess cells.
2. C.
For a living thing to remain alive, it must continue to carry out biochemical processes that maintain life. Most of these biochemical processes require water in order to occur, thus a living organism has to take in sufficient water in order to stay alive.
3. B.
Prokaryotes refers to those living organisms who do not possess a true nucleus and which lack membrane bound organelles in their cells. Prokaryotic cells are not well defined. Bacteria are a large group of unicellular micro organism and their cells is prokaryotic in nature.
4. D
The cell theory took years; close to 200 years to be developed and it involved the inputs of many scientists all over the world. Robert Hook was the first scientist to discover the cell, this was made possible by the help of a microscope. The cell theory continue to develop long after Robert Hook is dead.
Answer:
Bioarchaeology is a discipline that studies human skeletal remains in an archaeological investigation; while forensic anthropology refers to the study of human skeletal remains in a criminal case
Explanation:
Bioarchaeology is a discipline centered on the study of skeletal remains in order to obtain useful information about past societies/civilizations such as, for example, health conditions. On the other hand, forensic anthropology investigates human skeletal remains within a legal and/or criminal investigation. This information may result useful to identify a dead person, find the cause of death, and estimate time since death.
Similarities:
-Both disciplines have a strong biology background (especially in zoology)
-Both disciplines are focused on skeletal analysis
Differences:
-Bioarchaeology is associated with the anthropological study of human societies, while forensic anthropology associated with legal investigations
Cell membranes are mostly made up of lipids (fats)
