Diuris are common orchids found in Australia. The flowers of this species display a large number of variations in color and mark
Strike441 [17]

From what we know, we can confirm that the variations in colors are a mechanism intended to protect the plants from predators.

<h3>Why is color a protection mechanism?</h3>

This can be observed throughout nature. Many poisonous organisms have evolved bright colors intended to be noticed. Over time, this has resulted in many predators avoiding prey with bright colors, in order to avoid the possibility of being poisoned.

Therefore, we can confirm that the variations in colors are likely a mechanism intended to protect the plants from predators.

What mass, in grams, of aluminum hydroxide will be required to prepare the 4 L of a 1.75 M solution?
brilliants [131]

Answer: 0.53g

Explanation:

No of moles= volume ×molarity/1000

We have the volume and the molarity

Volume=4L

Molarity=1.7M

No of moles = 4×1.7/1000

No of moles= 0.0068moles

Remember also that

No of moles= mass given/molar mass

Molar mass of Al(OH)3

Al= 27

O=16

H=1

Molar mass = Al+(O+H)3

Molar mass= 27+(16+1)3

Molar mass= 27+(17)3

Molar mass = 27+51

Molar mass= 78g/mol

To get the mass

Mass given = no of moles × molar mass

Mass= 0.0068×78

Mass= 0.53g

Which scientist performed the cathode ray experiment leading to the discovery of electrons
SVETLANKA909090 [29]

The scientist that performed the cathode ray experiment leading to the discovery of electrons is J.J. Thomson.

<h3>What is a cathode ray?</h3>

A cathode ray is a tube that contains negatively charged electrode( that is the cathode) which emits electrons when heated at a low pressure.

The cathode ray was used by the scientist, J.J. Thomson to find the ratio of charge to mass (e/m) of the electrons.

Therefore, the scientist that performed the cathode ray experiment leading to the discovery of electrons is J.J. Thomson.
