The type of muscle tissue that does not contain gap junction is SKELETAL MUSCLES.
Gap junction function by allowing the free diffusion of ions and small molecules between two cells. The number of gap junction between any two cells will vary and will depend on the type of cell they are.
Answer: The plant structures are correctly paired with its functions
Explanation: Dermal tissue: protected soft tissues of plants and controls interactions with plant surroundings(It covers the outer surface of herbaceous plants)
Parenchyma tissue: functions in storage, photosynthesis and bulk of ground and vascular tissue
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:
Asexual reproduction is through the formation of asexual spores. They are produced by one parent only and are genetically identical to that parent (Mitosis).
Sexual reproduction in the fungi has three stages plasmogamy, karyogamy, and meiosis.
Explanation:
AR: Spores may be dispersed by moving water, wind, or other organisms. The spores far from the parent organism. This helps to ensure that the offspring will not have to compete with the parent for space or other resources.
SR: Sexual reproduction occurs when spores from two parents fuse and form a zygospore.
D because they are complete systems
