Answer:
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.
There are two main types of circulatory systems: 1. open circulatory systems and closed circulatory systems. Open circulatory systems are systems where internal organs and body tissues are surrounded by circulatory fluid. This fluid is called hemolymph, and it's pretty much like blood, except that it doesn't contain oxygen transporting cells.
2. The closed circulatory system of some mollusks and all vertebrates and higher invertebrates is a much more efficient system. Here blood is pumped through a closed system of arteries, veins, and capillaries. Capillaries surround the organs, making sure that all cells have an equal opportunity for nourishment and removal of their waste products. However, even closed circulatory systems differ as we move further up the evolutionary tree.
Answer:
A) It uses less energy to make something from recycled materials than from new materials.
Explanation:
When a recycled material is used to make a new product, it conserves energy because the recycled materials have already been processed once; so making something from it for the second time uses less energy-intensive than the first. For example: Making new aluminium from old products uses 95% less energy than making it from scratch.
Hence, the correct answer is "A)"
Answer:
Glucose Transport
Explanation:
Glucose Transport is a highly regulated process accomplished mostly by facilitated diffusion using carrier proteins to cross cell membranes.
