Answer:

Answer is all of the above.

Explanation:

Reproductive isolation can be described or explained as a collection of mechanisms such as behavioral and ecological mechanisms preventing the members of two or more groups of different species that mate from producing offspring, or if their mating eventually produced offspring, the offspring will not be fertile.

There are things that can make reproductive isolation to occur, they include

* Lack of fit between or among sexual organs.

) is every minimum bottleneck tree of g a minimum spanning tree of g? prove or give a counter example
mote1985 [20]

The answer is false. To explain further, let G have vertices {v1, v2, v3, v4}, with ends between each pair of vertices, and with the mass on the edge from vi to vj equal to I + j. Then each tree has a bottle neck edge mass of as a minimum of 5, so the tree containing of a track through vertices v3, v2, v1,v4 is a least bottleneck tree. It is not a least spanning tree, though, subsequently its total mass is greater than that of the tree with edges from v1 to every single vertex.

For energy, a plant breaks apart some of the small sugars it builds. What does the plant do with the rest of its small sugars?
balandron [24]

Answer:

The plant stores them as starch

Explanation:

A typical plant synthesizes sugars from photosynthesis by using water and carbon dioxide.

6CO_2 + 6H_20 + energy --> C_6H_1_2O_6 + 6O_2

Parts of the sugar synthesized via photosynthesis is used to generate energy during respiration. The energy generated is useful for other metabolic processes in the plant's body.

C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_20 + energy

<em>The remaining sugar is utilized in the synthesis of starch and stored in the various tissues of the plant.</em>

  • In comparison with both of these;

we know that metre per second is the SI unit of average speed and hence the answer is <u>meters</u><u> per </u><u>second</u>.
