How does the structure of the stigma aid in pollination?

Chemistry

inysia [295]4 years ago

If the stigma is messed up it is hard for bees or insects to pollinate because the way they pollinate is by eating the nectar from the stigma and stick the pollen on their body and stick it on the stigma.

But if there is no stigma=no pollination
A good example of a model is a lily

Which statement best describes what happens when a person sees an orange t-shirt?
Alex73 [517]

Answer:

The correct answer is - Orange light reflected from the t-shirt enters human eyes.

Explanation:

Human eyes and brain are altogether able to detect the color of the object by translating the light which is reflected by the object and transmitted by the light receptors in the eyes ad brain translate light to color.

The objects are able to absorb some colors and reflect others on the basis of their wavelength, The reflected colors are detected by our eyes and brain and objects appear to be a particular color. like here, the orange color is reflected by the t-shirt and enters in human eyes.

Explain what "LEO the lion goes GER" means based upon what you have learned
olchik [2.2K]

"LEO the lion goes GER" means based upon the oxidation and reduction reactions.

<h3>What is oxidation and reduction reaction?</h3>

Oxidation reactions are those reactions in which lossing of electrons are taking place from the substrate molecule and in reduction process gaining of electrons is done by substrate molecules.

The phrase "LEO the lion goes GER" is used in the context of oxidation and reduction reactions. Meaning of the terms:
LEO → Lose electrons = oxidation

GER → Gain electrons = reduction

Hence the given line is based on oxidation and reduction.

A voltaic cell that uses the reaction PdCl2−4(aq)+Cd(s)→Pd(s)+4Cl−(aq)+Cd2+(aq) has a measured standard cell potential of +1.03
Ghella [55]

Answer : The balanced two-half reactions will be,

Oxidation half reaction : Cd(s)\rightarrow Cd^{2+}(aq)+2e^-

Reduction half reaction : Pd^{2+}(aq)+2e^-\rightarrow Pd(s)

Explanation :

Voltaic cell : It is defined as a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy. It is also known as the galvanic cell or electrochemical cell.

In the voltaic cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode.

The given redox reaction is:

PdCl_4^{2-}(aq)+Cd(s)\rightarrow Pd(s)+4Cl^-(aq)+Cd^{2+}(aq)

The balanced two-half reactions will be,

Oxidation half reaction : Cd(s)\rightarrow Cd^{2+}(aq)+2e^-

Reduction half reaction : Pd^{2+}(aq)+2e^-\rightarrow Pd(s)
