Answer:
D
Explanation:
In multicellular organisms, the body is a system of multiple, interacting subsystems. Subsystems are groups of cells that work together to form tissues. Interactions are limited to the circulatory, excretory, digestive, respiratory, muscular, and nervous systems.
Answer:
Extreme warm weather, glacial melting, rising sea levels, Ocean Acidification,Animal Migration and Extinction of Species, The Increase of Health Issues and Costs.
Answer: Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle.
Explanation:
Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth's geologic activity takes place at plate boundaries.
Answer: The correct answer is D) The number of chromosomes remains the same in mitosis and is reduced by half in meiosis.
Explanation-
Mitosis and meiosis are the two forms of cell division. Mitosis occurs in all the living organisms. In mitosis, cell divides into two daughter, each having equal number of chromosomes with that of the parental cell. It is also a process of asexual reproduction.
Whereas, meiosis typically occurs in sexually reproducing organisms during gamete formation. In this process, the number of chromosomes are reduced to half as the homologous chromosomes are separated.
Thus, the number of chromosomes remains the same in mitosis and it is reduced by half in meiosis.
B. concept map
Explanation:
The best model to use is a concept map.
The concept map would be a very good one in showing differences between animals with backbone and those without backbones.
A concept map is a graphical model map. It uses pictures, illustrations, graphs e.t.c to present and explain an idea.
They usually begin with the most important idea and then branches off to the subsets.
It is a good way of pitching differences between things.
