How do you perform cunnilnglus?
the best way i have found is to gently but firmly lick from the clitoral hood to the vaginal opening you can use your fingers or thumb to create brush stokes over the clitoral hood as you are licking don't neglect the rest of her body keep good eye contact and maybe rub her breasts and body with your free hand also dipping you tongue in and out in rapid secession to the virginal opening and be a great teaser not all women are the same so don't be shy and just ask them to show you with your hand or to Gide your head were the feel most satisfyed women respond to confident men not shy boys so man up and have fun.
Why can the Calvin cycle work at night but the photosystems connot?
Calvin cycle occurs in the stroma of the chloroplast and utilizes the NADPH and ATP produced in the process of light dependent reaction( or what we say the z- scheme reaction). If both are present then the Calvin cycle can occur even at night. because the Calvin cycle is light independent reaction.
whereas the photo system as asked in the question actually refers to light dependent reaction( or what we say the z- scheme reaction) requires light.
Though the reaction is not triggered by light, it does need the products produced in the "light-dependent " process.
Why would a plant be put in the dark before doing an experiment for photosynthesis?
so that it cannot make any nutrients/energy from photosynthesis (because there is no light), therefore all its nutrients are used up before the experiment begins....so it is a reliable test (nutrients made by photosynthesis before experiment would cause unreliable results because it wouldn't give proof that light is needed for photosynthesis to occur)
Green pigment necessary for photosynthesis?
- Plant cells have an organelle (a feature) inside them called chloroplasts. These chloroplasts contain GREEN PIGMENTS called chlorophyll. Chlorophyll absorbs red and blue light in order for photosynthesis to take place as:
Carbon dioxide + Water -l-i-g-h-t-> Glucose + oxygen
The green light is reflected giving a plant its green color.
________________________________________________________
- Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll pigments.
- In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane.
Where in a tree does photosynthesis occur?
Photosynthesis occurs in the leaves of a tree. The chloroplasts in the cells of the leaf are where photosynthesis takes place, using sunlight to convert carbon dioxide and water into glucose and oxygen.
What are the are materials of photosynthesis?
The 3 materials needed for photosynthesis are water, carbon dioxide, and sunlight. These 3 materials combined enable the plant to make a sugary substance known as glucose. 6 molecules of water+6 molecules of carbon dioxide=1 molecule of sugar+6 molecules of oxygen* *=The plant doesn't need the oxygen so it releases it into the air. That's how we get our oxygen. :)
Is carbon dioxide also light energy?
The energy to run photosynthesis is not found in the carbon dioxide. The carbon dioxide provides a source of carbon in order to make glucose. The energy that runs photosynthesis is found in the photons (light energy) that strike the photosystems of the chloroplasts, as well as the electrons stripped from water molecules.
How is photosynthesis a transfer of energy?
The process turns light energy into chemical potential energy (the sun's light is used to create sugars).
What organelle is responsible for converting light energy into glucose molecules?
The chloroplasts in plant cells take energy from the sun and in a series of reactions, stores it in glucose.
What plant tissue where photosynthesis?

Why plant cells undergo both photosynthesis and respiration?
Yes. They use photosynthesis to produce sugar from sunlight, and cellular respiration to digest the sugar for energy (ATP).
Which is a role in photosystem in the light reactions?
it is the first phase. it is making NADPh and ATP.
Where does photosynthesis happen on a leaf cell?
Photosynthesis mainly occurs in the chloroplasts of leaf cells. The chloroplasts contain chlorophyll, the green pigment that captures light energy and converts it into chemical energy to produce glucose. This process takes place in the mesophyll cells of the leaf.
Why can't non-vascular plants grow tall?
Nothing would 'happen.' There are many herbaceous plants that grow to over 2 meters, for example Giant Hogweed and Gunera.
What is the relationship between photosynthesis respiration and plant cells?
Cellular respiration is a form of oxidation that produces energy by combining glucose and oxygen. Photosynthesis is combining oxygen with sunlight and water to create glucose, a plant's energy form (ours is ATP, Adenosine Triphosphate). They're both energy making processes in organisms, to put it simply. Hope I helped. I'm in grade 7 bio right now and we learned this:)

Does photosynthesis store or release glucose?
Its creates starch.
Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. the reaction from start to finish is; 6CO2 + 6H2O (+ light energy) C6H12O6 + 6O2.This reaction is also responsible for the production of our oxygen.
What is the importance of computer in biochemistry?
Computers play a vital role in almost every aspect of Modern Chemical Engineering
1. Chemical engineers use super-computers to simulate complex chemical processes and plant operations.
2. Chemical engineers use Computational Fluid Dynamics to simulate flow systems and advanced heat transfer problems.
3. Chemical engineers use matlab, polymath, wolfram mathematica to solve complex differential equations for unique solutions.
4. Chemical engineers apply Aspen Computer Technology to simulate unit operations and processes.
5. Chemical engineers may code in various program interfaces to solve particular problems and numerical methods.
What is the largest living thing in the world?
THE GREAT BARRIER REEF I AM NOT LYING LOOK IT UP ON IGOOGLE AND TYPE IN
What is the largest living thing in the world AND IT WILL SAY LARGEST ORGANSIMS WIKIPEDIA AND IT WILL TELL YOU A LOT MORE ABOUT THE GREAT BARRIER REEF.
This question is actually debatable. The blue wale is undoubtedly the largest single organism on the planet. However, the tree known as the Aspen reproduces by producing offshoots from its roots and generating clones of itself. These clones are actually still attached to the parent tree and are still considered the same organism. Entire aspen groves can consist of just one individual even though many "trees" are present. Because the total biomass of these collective individuals is so massive the aspen is the largest living thing. A grove in Utah named Pando covers 106 acres and 6,000 tons. Pando is considered to be the largest living thing.
It is accepted as the Great Barrier Coral Reef. The largest animal is the blue whale.
What is the source of energy needed to start the photosynthesis reaction?
light and ATP
it gives the plant the ability to make it's own food, if it doesn't make its own food it is a consumer not a producer
It receives energy from light
It produces energy as ATP and NADH
Source of energy is light. Meaning of "photo" is light
Sun
Photo means the light. So it needs light energy. This energy is obtained from sun
sunlight.
What do plants use sugar made from photosynthesis for?
Photosynthesis is a process in which the plant produces sugar using the sun's rays that the leaves collect. They use this sugar to feed the plant, as they cannot forage for food, for they have to make it themselves. I hope I could help!
Where is the second stage of photosynthesis occur?
The second step of photosynthesis happens between the chloroplasts, rather than inside of them. This particular step is also independent of light, so if the light suddenly goes away for some reason, it doesn't totally stop the photosynthesis all at once.
How do you compare the different roles of photosystem 1 and photosystem 2 in photosynthesis?
The structure of photosystem I in a cyanobacterium ("blue-green alga") has been completely worked out. It probably closely resembles that of plants as well. It is a homotrimer with each subunit in the trimer containing: * 12 different protein molecules bound to * 96 molecules of chlorophyll a ** 2 molecules of the reaction center chlorophyll P700 ** 4 accessory molecules closely associated with them ** 90 molecules that serve as antenna pigments * 22 carotenoid molecules * 4 lipid molecules * 3 clusters of Fe4S4 * 2 phylloquinones Photosystem II is also a complex of * > 20 different protein molecules bound to * 50 or more chlorophyll a molecules ** 2 molecules of the reaction center chlorophyll P680 ** 2 accessory molecules close to them ** 2 molecules of pheophytin (chlorophyll without the Mg++) ** the remaining molecules of chlorophyll a serve as antenna pigments. * some half dozen carotenoid molecules. These also serve as antenna pigments. * 2 molecules of plastoquinone
