Bees are commonly found near flowering plants.
(a) Describe how bees help plants to reproduce.
Answer:
bees like flowers because they have pollen in their wings, and it makes them happy, and that’s nice. They make beautiful little things that can be used to make honey.
Explanation:
The foundation of the best honey is flowers and pollen. When they’re all in bloom, it’s a wonder for bees to come to them—not because of their beautiful colours but rather for how much sweetness there is in them. The smell alone makes every person nearby fall in love with bees. The only downside? The flowers die within weeks when exposed to too much pollen. They can only take so many blooms before it becomes too toxic for humans to eat, even if they don’t have to go through the hassle of killing a human to obtain them.
But that doesn’t mean bees hate the sight of flowers.
It has been said that flowers are what make people happy. That they can make anyone smile despite the circumstances. And maybe if people saw more flowers they would be happier? But it doesn't always work like that.
The plants around her garden
Answer:
PollinationExplanation:
In its natural state, the flower is inverted with the standard petal at the bottom. when a heavy insect such as BEE visits the flower, it lands on the standard petal.The Insects follow the nectar guide into the flower.The insect forces its way in between the two wing petals and moves in to collect the nectar.The insect's back forces the keel petal upwards to expose the stigma and anthers. The stigma and anthers brush against the hairy back of the insect. when this happens, some pollen grains from the anther stick to the hairy back of the insect. At the same time, pollen grains on the insect's back (from another flower which the insect had visited earlier) are transformed into a sticky stigma.when the insect leaves the flower, the keel springs back to its original position to enclose the stamen and the stigma again.Refer to Attachment

Consider these versions of The War of the Worlds. Excerpt 1, from H. G. Wells's novel The War of the Worlds: The common round the sand pits was dotted with people, standing like myself in a half-fascinated terror, staring at these creatures, or rather at the heaped gravel at the edge of the pit in which they lay. And then, with a renewed horror, I saw a round, black object bobbing up and down on the edge of the pit. It was the head of the shopman who had fallen in, but showing as a little black object against the hot western sun. Now he got his shoulder and knee up, and again he seemed to slip back until only his head was visible. Suddenly he vanished, and I could have fancied a faint shriek had reached me.

According to the chemiosmotic hypothesis, what provides the energy that directly drives atp synthesis?.
Explanation:
According to the chemiosmotic hypothesis, ATP is produced by due to the proton gradient created across the mitochondrial membrane. The essential components required for chemiosmosis are proton pump, proton gradient and ATP synthase. ATP synthase is an enzyme which helps in ATP synthesis. The enzyme ATP synthase has two part
F0 andF1.F0 is the part which transports protons across the membrane as a transmembrane channel while configuration changes in F1
activates the enzyme. They phosphorylate ADP i.e., add one more phosphorus group to the ADP and converts ADP(adenosine diphosphate) to ATP (adenosine triphosphate). The proton gradient developed across the membrane is the driving force of ATP synthase.

Photosynthesis is a means of converting light energy to chemical energy. Explain what this statement means.
Answer:
photosynthesis, the process by which green plants and certain
other organisms transform light energy into chemical energy .
During photosynthesis in green plants, light energy is captured
and used to convert water, carbon dioxide, and minerals into
oxygen and energy-rich organic compounds.
also
During the process of photosynthesis, light penetrates the
cell and passes into the chloroplast. The light energy is
intercepted by chlorophyll molecules on the granal stacks.
Some of the light energy is converted to chemical energy.
During this process, a phosphate is added to a molecule to
cause the formation of ATP(Adenosine triphosphate)
Let's take a short look at photosynthesis before moving on to this topic.
It is an exergonic, light-dependent, biological, oxidoreductive, energy-yielding process. Where sugars or (CH2O)n are produced energetically by reducing CO2.
Although Co2 is essentially prevalent in nature, it does not break down into sugars since the reaction is thermodynamically possible.
Right after sunlight strikes the surface of the leaf, there are these little components known as reaction centers or energy harvesting cores, which are surrounded by antenna complexes. These antenna complexes are normally composed of chl a, chl b, xanthophyll, carotenoid, etc.
Here, the antenna complexes serve as filters, allowing just the necessary amount of flux to depart the outershelled electron of the chlorophyll molecule via energy activation states (of different kinds).
As the pigment system activates the chlorophyll molecule, the energy from the light is now transferred to chemo potential energy, which is subsequently employed in the process to oxidize the water molecule by the Kok clock mechanism.
Now this is an rather interesting cycle having multiple energy states, from Ground (SO) to maximum (S4) notice that the energy was first required to move on to next step in intermediates but as soon as it reached S4 or max state it oxidized water and this energy is actually enough to reduce Carbon di Oxide to sugar.
(Attachment #1)
If I'm not incorrect, the conversion works like this.
(Attachment #2)
As a result, it needs to be activated gradually in order to build up enough energy to pass the energy barrier.
NOTE:
As you can see, plants don't purposefully create oxygen, but why do they continue to do so? It does this because its primary goal is to turn sugar into oxygen, which it then converts into water that actually vaporizes while keeping the system cool.

Viruses chose to store their data in RNA so that they can make changes as their hosts develop immunities.
The specimen is of virus. The correct option is A.
Thus, A virus is an infectious microorganism made up of a protein-coated segment of nucleic acid (either DNA or RNA).
A virus can't multiply by itself; it has to infect cells in order to utilise the host cell's components to make copies of itself. A virus frequently causes harm to the host organism by killing the host cell in the process.
