Answer:plants
Explanation:the greener and more vegetated ecosystem is more healthier with plenty of habitat,food and moisture provided for other living organisms and also attracting agents like pollinators .
The answer is stem cells. Normal stem cells and germ cells can also be said to be immortal
Tin, because it has five energy levels with four electrons in the fifth level
.
Explanation:
Tin has an electronic configuration as
1s2,2s2,2p6,3s2,...........4d10, 5s2,5p2
They have four valence electrons in their outer shell
Among the four diagrams given Tin is least reactive because the atomic radius of tin is largest among all four options. Due to large atomic radius electronegativity decreases and hence Tin is the least reactive element among Neon, Chlorine, gallium and tin.
The electronegativity of an element is its tendency to complete its octet by attracting electrons towards itself. Also tin is at the lowest place in the periodic table among all the four mentioned elements, its ionization energy is also low hence less electronegative and least reactive.
Answer:
Water, fish
Explanation:
The limiting factors are the water of course and the organisms living in the lake.
