True. A nuclear family includes a couple and their dependent children. Now a days there are many types of families like single parent families, extended families, childless families, step families, etc.
Cells
All living things are made of cells, use energy, respond to stimuli, grow and reproduce, and maintain homeostasis. All living things consist of one or more cells. Cells are the basic units of structure and function of living organisms. Energy is the ability to change or move matter.
Hope this helps:)
Have a great day!
Answer: The system’s host star, called TRAPPIST-1, is what is known as an ultracool dwarf.
Explanation:
Also called 2MASS J23062928-0502285, TRAPPIST-1 is an ultracool dwarf star that hosts three planets: TRAPPIST-1b, c, and d.
Never before planets had been found around ultracool dwarf stars, and they are considered as potentially habitable and, therefore, suitable for life outside our solar system.

Let a, b, c be the coefficients of the balanced reaction
a SF₄ + b O₂ ⇒ c OSF₄
The atom counts for each element among the reactants should be the same as with the products:
• S : a = c
• F : 4a = 4c
• O : 2b = c
If b = 1, it follows that a = c = 2. So the balanced reaction is
2 SF₄ + 1 O₂ ⇒ 2 OSF₄
