what describes an ion
1) In 250-300 words describe the light reactions in photosynthesis
2) In 200-250 words describe the dark reactions in photosynthesis
In light reaction it includes the use of light energy for the two molecules. The dark reaction is a light independent reaction.
Describe the light reaction in photosynthesis and also describe the dark reaction in photosynthesis?
Light Reaction:
In light reaction it includes the use of light energy for the two molecules which is needed for the next stage of photosynthesis the energy storage molecule ATP (Adenosine tri phosphate) and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts. During the light reaction the chlorophyll absorbs light energy which excites some pigments molecules to higher energy levels.
Dark reaction:
The dark reaction is also called the carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from carbon dioxide and water molecules. The dark reaction occurs in the stroma of the chloroplast, where they use the products of the light reaction.
So we can conclude that in light reaction it includes the use of light energy for the two molecules. The dark reaction is a light independent reaction.

how is being wrong a part of science
Answer:
Error causes results that are inaccurate or misleading and can misrepresent nature. Scientifically accepted values are scientists' current best approximations, or descriptions, of nature.
Explanation:
Error causes results that are inaccurate or misleading and can misrepresent nature. Scientifically accepted values are scientists' current best approximations, or descriptions, of nature.
Answer:
Being wrong is a part of Science because in Science you won't know everything. In Science we use hypotheses or we guess what we think will be the results. It's okay to be wrong because you can learn by experimenting and discovering new things. People make new discoveries and also scientists or people who work in the field of science aren't always correct either. It is important to be wrong sometimes because you can learn new things. Science has a whole process and it can change what you thought would be right. Being wrong in Science or learning from being wrong can be helpful because people in the future can then know the reasoning to why that is the answer. It is an essential thing honestly.

Do plants die becuase of too much sun or too much water??
Answer:
They can die from both
Explanation:
Plants need sun but too much sun can dehydrate or damage the plant. As if too water plants need air too breath so adding too much water can drown them
Answer:
Both
Explanation:
Plants harvest energy from the sun with the help of chlorophyll and carotenoid, two photon-capturing molecules. But if the plants are exposed to too much sun, these molecules absorb more energy than they can handle and generate reactive species of oxygen that can destroy the plant.
and
Roots growing in waterlogged soil may die because they cannot absorb the oxygen needed to function normally. The longer the air is cut off, the greater the root damage. The dying roots decay and cannot supply the plants with nutrients and water. Damage caused by over watering is frequently misdiagnosed as pest damage.

Which of the following uses carbon from glucose as both an electron donor and an electron acceptor?
anaerobic respiration
aerobic respiration
fermentation
A & B
B & C
Aerobic respiration and fermentation use carbon from glucose as both an electron donor and electron acceptor.
What is aerobic respiration?
The process of aerobic respiration, which takes place in the presence of oxygen and converts glucose into ATP (Adenosine Triphosphate), gives the cell energy.
The procedure includes several phases, such as glycolysis, acetyl coenzyme A synthesis, citric acid cycle, electron transport chain, etc.
Carbon dioxide, water, and ATP energy molecules are the byproducts of aerobic respiration. A chain of electron donors and acceptors is involved in the electron transfer process.

What conditions are needed to form organic molecules from inorganic molecules
Answer:
Presence of inorganic molecules with lightning and intense radiation
Explanation:
This process of the formation of organic molecules from inorganic molecules is called abiogenesis. It is believed that this is how the first organic molecules were created in early earth about 3.8 billion years ago. The classic 1952 Miller–Urey experiment attempted to replicate the condition of the early earth. They replicated lightning strikes (using electric parks) in a glass with greenhouse gases believed to have been the major constituents of early earth's atmosphere like methane. They were able to form primitive organic molecules from this experiment.

Thomas is playing baseball with Matt. Thomas hits the 0.14 kg baseball and it moves with a velocity of 50 m/s. Assuming all energy is conserved, what is a height the ball can reach if his straight upward?
What can we find with mass and velocity?
If all energy is conserved, that means no energy is lost so KE will eventually equal GPE at the peak of the balls height what does this mean we can do?
We can find the momentum of the body using mass and velocity.
What is the momentum of a body?
Linear momentum, translational momentum, or simply momentum is the product of an object's mass and velocity in Newtonian physics. It is a vector quantity with magnitude and direction. If m is an object's mass and v is its velocity (also a vector quantity), then p = mv is the object's momentum.
We can find the momentum of the body using mass and velocity by the relation p = mv.

The deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.
In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).
According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.

An isotonic environment outside a cell has _______% salt, the same as the inside of the cell.
An isotonic environment outside a cell has same amount of salt, the same as the inside of the cell.
What is isotonic solution?Isotonic solutions are the ones that have the similar concentration of water as well as solutes as cell cytoplasm. Because there is no net gain or loss of water, cells in an isotonic solution will neither shrink nor swell.
When a cell is immersed in an isotonic solution, there is no net flow of water into or out of the cell, and the volume of the cell remains constant.
If the concentration of solutes outside the cell is the same as the concentration inside the cell and the solutes cannot cross the membrane, the solution is isotonic to the cell.
Thus, it has same percentage of salt inside and outside.
