what essential chemicals do the light dependent reactions obtain from the light independent reactions

Answers

Explanation:

Light Reactions: Light-dependent reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where the Calvin cycle takes place.

The energy storage molecule ATP and the reduced electron carrier NADPH are produced by the light-dependent processes using light energy, which is required for the subsequent stage of photosynthesis.

What are the products of the light-independent reactions check all that apply?

In order to make ATP and NADPH, the light-dependent processes of photosynthesis must first collect energy from the sun.Then, these two molecules that store energy are employed in the light-independent reactions. Two different types of energy-carrier molecules, ATP and NADPH, store the solar energy in the light-dependent reactions.These molecules' stored energy is contained in the bond that binds one atom to the molecule.It is a phosphate atom for ATP and a hydrogen atom for NADPH. The cell has the material it needs to create carbohydrate molecules once the energy from the sun is processed and packed into ATP and NADPH.Carbon atoms will form the backbone of the carbohydrate molecules created. The protein ferredoxin receives electrons from the pigment P700 in its reaction center. Ferredoxin can then donate the electrons to either the electron transport chain to produce more ATP or to the electron carrier NADP+ to make NADPH. The pigment chlorophyll in the thylakoid membranes of the chloroplast is able to absorb solar energy during these reactions.The second stage of photosynthesis uses the molecules ATP and NADPH, which are temporarily transferred the energy to. Chlorophyll absorbs solar energy during the light-dependent reactions and transforms it into chemical energy that is then stored.The chemical energy obtained during the light-dependent reactions powers the construction of sugar molecules from carbon dioxide in the light-independent reactions. Plants require three elements for photosynthesis: carbon dioxide, water, and sunshine. The reactions that depend on light include those that use it to split water, create ATP, and NADPH.The processes that use ATP and NADPH to repair carbon dioxide in order to produce the three-carbon sugar glyceraldehyde 3 phosphate are known as light independent reactions. NADP, ADP, and water molecule reactants are used in the light reaction.After the light processes are finished, the molecules ATP, NADPH, and oxygen are produced, the last of which is already regarded as a byproduct of photosynthesis.

Do you think there should be regulations on industries that make fertilizers and farmers who use fertilizers to ensure that excess nitrogen does not reach water ecosystems? Why or Why not? Write at least five sentences defending your answer.

Answers

Given what we know, we can confirm that there should in fact be regulations on fertilizer manufacturers and farmers who use fertilizers to ensure that excess nitrogen does not reach water ecosystems due to its negative effects on the ecosystems.

What is Nitrogen?Nitrogen is an element that is most often found in a gaseous state.It is color and odorless.It is found in the air, water, and almost everywhere else around us, but in low quantities. It can form toxic gases such as ammonia when in high concentrations in the air.

Why can it be harmful in excess?Excess nitrogen in water is very bad due to the effect on algae. Contrary to what we may initially believe, excess nitrogen can help algae to grow at very high rates.However, these algae blooms sap the oxygen from the water at increased rates and damage if not kill all other marine life in the area as a consequence.

Therefore, regulations should be in place for fertilizer manufacturers and farmers who use fertilizers to ensure that excess nitrogen does not reach water ecosystems due to its negative effects on the ecosystems.

What are the states of energy? List the Laws of Thermodynamics.

Answers

Answer:

The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium.

Explanation:

What are the states of energy? List the Laws of Thermodynamics.
Answer: The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.

Paragraph: Discuss the three laws of thermodynamics.
Key Points

The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system.
The second law of thermodynamics states that the entropy of any isolated system always increases.
The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
Terms

absolute zeroThe lowest temperature that is theoretically possible.
entropyA thermodynamic property that is the measure of a system’s thermal energy per unit of temperature that is unavailable for doing useful work.

System or Surroundings

In order to avoid confusion, scientists discuss thermodynamic values in reference to a system and its surroundings. Everything that is not a part of the system constitutes its surroundings. The system and surroundings are separated by a boundary. For example, if the system is one mole of a gas in a container, then the boundary is simply the inner wall of the container itself. Everything outside of the boundary is considered the surroundings, which would include the container itself.

The boundary must be clearly defined, so one can clearly say whether a given part of the world is in the system or in the surroundings. If matter is not able to pass across the boundary, then the system is said to be closed; otherwise, it is open. A closed system may still exchange energy with the surroundings unless the system is an isolated one, in which case neither matter nor energy can pass across the boundary.

The First Law of Thermodynamics

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

A way of expressing the first law of thermodynamics is that any change in the internal energy (∆E) of a system is given by the sum of the heat (q) that flows across its boundaries and the work (w) done on the system by the surroundings:

Δ
E
=
q
+
w
Δ
E
=
q
+
w

This law says that there are two kinds of processes, heat and work, that can lead to a change in the internal energy of a system. Since both heat and work can be measured and quantified, this is the same as saying that any change in the energy of a system must result in a corresponding change in the energy of the surroundings outside the system. In other words, energy cannot be created or destroyed. If heat flows into a system or the surroundings do work on it, the internal energy increases and the sign of q and w are positive. Conversely, heat flow out of the system or work done by the system (on the surroundings) will be at the expense of the internal energy, and q and w will therefore be negative.

The Second Law of Thermodynamics

The second law of thermodynamics says that the entropy of any isolated system always increases. Isolated systems spontaneously evolve towards thermal equilibrium—the state of maximum entropy of the system. More simply put: the entropy of the universe (the ultimate isolated system) only increases and never decreases.

A simple way to think of the second law of thermodynamics is that a room, if not cleaned and tidied, will invariably become more messy and disorderly with time – regardless of how careful one is to keep it clean. When the room is cleaned, its entropy decreases, but the effort to clean it has resulted in an increase in entropy outside the room that exceeds the entropy lost.

The Third Law of Thermodynamics

The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero. The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has. Specifically, the entropy of a pure crystalline substance (perfect order) at absolute zero temperature is zero. This statement holds true if the perfect crystal has only one state with minimum energy.

1.There are some characteristics that are inherited from your parents, shape of blood cells is one of them. In sexual reproduction, offspring are formed when sperm of male combine with egg of female organism.Therefore, some characteristics comes from male organism and some from female organism. In sexual reproduction, diploid organism is formed because half of genes comes from male and half comes from female.

2.Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents

3.A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredit

4.Mendel made sure to study 30,00 pea plants when he presented his data to the community. Another example is when Mendel painstakingly removed all of the immature anthers from the plant’s flowers before the cross.Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).

5.A pea plant could have a copy of the height gene that coded for "tall" and a copy of the same gene that coded for "short." But the tall allele is "dominant," meaning that a tall-short allele combination would result in a tall plant
