In 1893, a large area of a national forest was home to mountain lions, coyotes, and bobcats as well as about 3,000 deer. The deer ate grass, and the mountain lions, coyotes, and bobcats ate deer.
Around 1900, hunters began killing large numbers of mountain lions, coyotes, and bobcats. By 1923, there were 100,000 deer in
this population
BOBCATS
MOUNTAIN
LIONS
COYOTES
DEER
GRASS
Using only the relationships between the plants and animals described above, which of the following statements could explain
why the population of deer increased so much?
The number of deer increased because without predators, the deer lived longer and had more offspring that also
lived longer.
The number of deer increased because populations are always increasing.
The number of deer increased because with fewer mountain lions, coyotes, and bobcats, the deer had more food to
eat.
There is not enough information to tell why the deer population increased.

answer; /// i do believe that the correct answer is (c)nuclear bond

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
