Answer: I think the answer is true
Explanation: If you think about it, the terrestial planets ( being venus, earth, mars, and mercury) are made up very little gas which are carbon dioxide, nitrogen and oxygen, and the gas giants ( being jupiter, saturn, neptune, and uranus) have gases such as hydrogen and helium. Thus meaning, the terrestial planets could be a part of it and the gas giants are the most. So yes, the answer is true.
The answer is probably B because white blood cells are part of the immune system, so help to fight diseases. The circulatory system helps to move the white blood cell around the body. Also, pathogens are disease causing organisms, and as you can see, they all relate very well. Hope i helped, have a nice day.
Three of the major characteristics used to classify organisms are cell structure, mode of nutrition and cellularity. These characteristics help scientists determine how organisms are similar to each other as well as how they are different from each other.
Classifying an organism according to its cell structure means determining if it is a prokaryote or eukaryote and then determining if the organism has a cell wall or other organelles, according to Dave Krupp of the University of Hawaii .
Mode of nutrition refers to how an organism gets its food. Organisms can be classified as autotrophs or heterotrophs. Autotrophs make their own food, while heterotrophs must eat other organisms to survive. If an organism is an autotroph, it can also be classified as a photoautotroph or a chemoautotroph. Stephen T. Abedon of Ohio State explains that photoautotrophs produce their own food using energy from sunlight. Chemoautotrophs produce food using the energy from electron-donating compounds.
Cellularity refers to how many cells an organism has and how those cells are arranged. Some organisms are single-celled, while others are multicellular. Advanced organisms have cells organized into tissues.
