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.To learn more about independent reactions refer

2) Why is the mixture of milk and bacteria incubated at 45 °C?
3) what causes the milk to thicken?
4) why does fermentation eventually stop?
5) Explain how making yogurt is a way of preserving the nutrients from milk.
It should be noted that milk is pasteurized at the start of the process in order to kill bacteria.
The mixture of milk and bacteria is incubated at 45 °C to kill the bacteria.The drop in pH causes milk to thicken. Fermentation is stopped when the alcohol concentration rises to a point where it kills the yeast cells.Lastly, making yogurt is a way of preserving the nutrients from milk as the bacteria ferment the milk thereby turning the lactose sugars to lactic acids.

How has vehicle fuel consumption in comparison to miles traveled changed since 1960? What is the likely cause for this change?
Answer:
After World War II, economic growth, population growth, rapid suburbanization, and the closing of some public transit systems led to more reliance on personal vehicles for transportation. The number of cars and trucks in the United States increased dramatically, as did the number of highways. One result of the rapid increase of motor vehicles was air pollution, especially in cities, that had serious impacts on public health and the environment.

this year there were 32 ants born in an ant hive. Due to the new pesticide that was used in the area, 32 died. With an overall population of 1000 ants in the hive, what is the change in population? Do you have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. Work for calculating the new population.
Answer:
0 change in population. I think.
Explanation:
first we are adding 32 ants to the total because 32 ants were born so 1000+32 = 1032.
Next we are subtracting 32 ants from the new total because a pesticinde was used in the area. So 1032 - 32 is 1000. 1000 was the original total so there was not a decrease in popualtion or an increase.
The fish shown here is normally found in a pond but is being studied in an aquarium. The amount of water and salt intake and excretion is measured as the fish maintains homeostasis. What scientific
question is most likely being asked based on the information in the model?
Based on the information in the question, we can infer that the question being asked is most likely "What mechanisms do fish use to maintain homeostasis in salt-water environments?".
What is homeostasis?Homeostasis is a series of regulatory processes by which an organism maintains core values (or range of values) necessary for everyday life.How to test the questionThe question is in the form of a hypothesis.This means that the scientist must first propose a possible solution to the question.Then, the scientist will make observations based on this question. In this case, it would seem the scientist has placed the fish into an environment that differs from its natural habitat, in order to observe how the fish maintains homeostasis.
Therefore, we can infer that the most likely question being asked is in regards to the way in which fish maintain homeostasis.
