Answer:
The Calvin cycle has two parts. First carbon dioxide is ''fixed''. Then ATP and NADPH from the light reactions provide energy to combine the fixed carbons to make sugar.
Explanation:
At the end of the Calvin cycle, ATP and NADPH are the molecules have the energy that originally came from light.
Calvin cycle reactions are referred to as light independent reactions, because they can take place in the dark, provided the products of the light reactions (ATP and NADPH) are provided.
Cells do not store large amounts of ATP and NADPH, so the Calvin cycle depends on these molecules being contributed again by light reactions.
In these reactions (each one of them catalyzed by a specific enzyme), ATP and NADPH are used up, the two final products of the transformation of light energy into chemical binding energy by the chloroplast.
The Calvin cycle uses energy-rich products of light reactions (ATP and NADPH) to incorporate three CO2 molecules (one at a time) into a three-carbon sugar phosphate.
The carbon atoms fixed in the form of sugar in the Calvin cycle eventually become the carbons of all the organic molecules present in plants, animals and almost any form of life.
Therefore, we can conclude that at the end of the Calvin cycle, ATP and NADPH are the molecules have the energy that originally came from light.

Can Plastic Waste Degrade Into The Soil?
Yes or no and explain
Answer:
Yes, but the process is too slow
Explanation:
We pack almost everything in this material and plastic has become a very normal occurrence in the modern world. Each year, people used 1.6 million barrels of oil just to make plastic bottles.
On the other hand, nature takes about 1000 years to develop a single plastic object, while plastic material takes about 240 years.

Which of the following is an example of haploid cells? cardiac cells nerve cells gametes muscle cells
Answer:
Gametes is an example of haploid cells.
Explanation:
Haploid cells are cells that contain a single complete set of chromosomes. Haploid cells in humans and other mammals, are usually the sex cells (egg and sperms) which are also called gametes that are produced during meiosis (a type of cell division). When the egg is fertilized by a sperm, it produces a diploid cell. Gametes contain 23 chromosomes in humans.

A random mutation occurs and the GGA codon is changed to CGA. What effect does this
substitution have on the amino acid being called for? Explain your answer.
Answer:
The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Explanation:
Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.
In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.
The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.
Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.
The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Due to Base Substitutions Mutations.
What happens when a mutation changes a codon?
A nonsense mutation refers to a base substitution in which the changed nucleotide transforms the codon into a stop codon.
Such a modification leads to a premature termination of translation, which can badly affect the formation of proteins.
Thus, Base Substitutions Mutations take place.

What areas can act as carbon sinks?
the atmosphere
O the Arctic and Antarctic
O oceans, soils and forests
O all of these
Answer:
O oceans, soils and forests
Explanation:
A carbon sink absorbs carbon from the environment. They do not release carbon to the environment.
The atmosphere is a good carbon source since it contains a significant amount of carbon dioxide gas.
Carbon is found in the ocean in dissolved form. Soils are also good carbon sinks. Forest trees use carbon for their life processes One very integral process where carbon is used up is at photosynthesis. The carbon is used to make food materials.Which chemical is released by 2
WBC's that produces a non-specific inflammatory response?
Answer:
inflammatory cytokines
Explanation:
In host cellular defense systems, non-specific immune responses are integral. It is a general white blood cell-mediated reaction where cells respond quickly to pathogenic infiltration.
Here, receptors on cells detect or even respond to signals from damaged, injured or stressed cells- these signals, such as inflammatory cytokines in a cytokine storm of molecules, in response to signatures shared by a wide range of pathogens.

8. D. All 4 statements are correct.
9. False
10. False
Explanation:
The process of photosynthesis converts carbon dioxide and water into glucose and oxygen while the in the process of cellular respiration, glucose and oxygen are converted to water and carbon dioxide and ATP is formed.
In photosynthesis, glucose is formed while in cellular respiration ATP is formed. The process of forming ATP and glucose are ways in which energy is cycled and oxygen cycle occur in the atmosphere. Energy can not be recycled but it is rather used. Only green plants carry out photosynthesis. Autotrophs are known to be primary producers.

Simulate a 24-hour day (12 hours of light, 12 hours of dark). How many snails and plants do you need to keep a stable environment? Explain any discoveries you make. This simulation is for Gizmo.
Answer:
One snail for two plants.
Explanation:
One snail and two plants we need to keep a stable environment because the snails help to clean up garden debris by feeding on them and their feaces has nitrogenous nature which is nutritive for the plants. So the plants get nutrients from the snail as well as carbondioxide gas used by the plants for the process of photosynthesis. So we can say that snails are important for maintaining a stable environment.
Gizmo technology helps build up an understanding of challenges and helps in developing interests.
For a stable environment, we will require one snail for two plants.
Snails are a very important part of nature as they balance the environment and the food web.
Snails feed on plants and dead decaying matter. That helps in keeping a balance.
The excretory waste from snails is nitrogenous in nature and aid in plant nutrition.
Hence, the plant can get nitrogen from Snails faeces, and also carbon dioxide required for the metabolic processes.
