What is meant by transpiration is a necessaru evil?
3241004551 [841]
In plants, transpiration is a process which is inevitable but potentially harmful, because it can cause loss of water. Loss of water can lead to wilting and eventual death of the plant. Even a little stress can interfere with the plant's growth process. 

But, at the same time, transpiration is necessary because of a number of reasons - the transpiration stream aids the processes of mineral absorption, water absorption, energy exchange, helps provide the plant with optimum turgidity, it helps the exchange of gases and so on.

vladimir1956 [14]

Answer:

texture

Explanation:

Elements have been classified into three categories namely; metals, non-metals and metalloids. This classification was done based on certain characteristics or properties possessed by each element. Some of the characteristics used are: lustre, malleability, conductivity, melting point, boiling point etc.

- Metals are very good conductors of heat and electricity whereas metalloids and nonmetals are not.

- Metals and metalloids shine when polished i.e. they are lustrous, whereas nonmetals don't

- Metals are malleable i.e. can be beaten into sheets.

Texture is not a property used to classify metals and metalloids.

Compare a natural meadow with a cornfield in terms of biodiversity. in your answer, be sure to address the: • number of species
Mademuasel [1]

In a cornfield, only one plant species has dominated the area, that is the corn plant. While in a natural meadow, multiple species of plants occurs of different species. The presence of the different types of plants in the meadow will interact more number of insects in it as compared to the corn field. This will lead to more interactions among the different species in a natural meadow. The greater biodiversity of the natural meadow than the cornfield will support it better.

In case of any natural disaster, or a pest attack, all the plants will be killed in a corn field and so will the insects dependent on them, but in a natural meadow, if one plant species is killed by a natural disaster, other will still be alive. Hence, the ability to survive is greater in natural meadow.
