Which of the following molecules is not needed for the Calvin Cycle?
a. CO2
b. ATP
c. NADPH
d. H2O
pls help
Answer:
c. NADPH is the correct answer .
Explanation:
Hey mate..!
NADPH molecules is not needed for the Calvin Cycle.
The correct answer is water as the water molecules are produced during photosynthesis.
Co2 produces the starch from sugar. ATP and NADPH are also used to convert sugar molecules during the Calvin cycle.
Carbon enters the Calvin cycle as CO2 and leaves as sugar. ATP is the power source, even as NADPH is the decreasing agent that provides high-power electrons to shape sugar. The Calvin cycle absolutely produces a three-carbon sugar glyceraldehyde 3-phosphate (G3P).
What is the Calvin cycle?The Calvin cycle is a technique that plant life and algae use to show carbon dioxide from the air into sugar, the meals autotrophs want to grow. Every dwelling element on Earth relies upon the Calvin cycle. Plants rely on the Calvin cycle for power and meals.
Thus it's clear that it has no water needed.

Which is the main function of carbohydrates in the body?
Translate the mRNA codons into the
amino acid sequence.
(DO put a comma and a space between the codons and make sure you spell out the names of amino acids!)
Answer:
mRNA sequence: AUG; GCU; AAU; UGU; UGA
protein sequence: Met-Ala-Asn-Cys-stop codon (Methionine-Alanine-Asparagine-Cysteine-stop codon)
Explanation:
Transcription is the process by which a fragment of DNA (e.g., a gene) is used as template to synthesize a complementary RNA sequence, usually a messenger RNA (mRNA) sequence that is then used to synthesize a protein by the process of translation. In RNA, Adenine bases are replaced by Uracil bases. During translation, each codon (i.e., each triplet of nucleotides of the mRNA) indicates a specific amino acid (according to the genetic code). UGA, UAA, and UAG are stop codons that signal the end or termination of translation.

Explanation:
For the study of a particular drug, Marcus proposes an experiment with a particular population. Approximately 200,000 people in the United States take this drug. He started out with a sample size of 300 people. First, he conducts research on the medical history of the people in his study. He collects the information using reliable sources. He decides to repeat the experiment using a larger sample size.
The missing part of the question is as follows:
Phrase indicates a limit to the scientific accuracy of the experiment?
Answer:
The correct answer is - a sample size of 300 people.
Explanation:
In the given research Marcus developed a drug that is already 200,000 people taking the drug, and the scientist takes sample size of only 300 people for the experiment.
The sample is very small as compared to the total population who participated in the research. A sample size of 300 people is very small compared to 200,000 people. Such a small sample size will not give the proper idea and any effective result, there would be chances to miss some aspect or effect of the drug to be missed, so, this can be the limiting factor to the experiment.

Which change would best aid a farmer in making the transition from conventional farming techniques to more sustainable farming techniques?
Answer:
The correct answer is - Rotate the types of crops grown.
Explanation:
Crop rotation is the practice of growing the different types of crops sequentially on the same field to improve nutrients in the soil for better soil health and helps in fighting pest and weed pressure.
Different crops required different nutrients and therefore, rotating crops helps to not exploiting the same nutrients again and again. Rotating crops also helps in removing weeds and pests as different weeds and different pests associate with different crops.

Answer:
1. Digestion helps to break down the food into simple, soluble form.
2. Name the process by which absorbed nutrients are utilized by the body?
Ans. Assimilation is the process by which absorbed nutrients are utilized by the body.
3. Where does initial digestion of protein take place?
Ans. Mechanical digestion of protein begins in the mouth and continues in the stomach and small intestine. Chemical digestion of protein begins in the stomach and ends in the small intestine. The body recycles amino acids to make more proteins.
4. Where is the water absorbed from undigested food in the digestive system?
Ans. Water from the undigested food is absorbed mainly in the large intestine.
5. Name one animal that lives on liquid food only.
Ans. Mosquito lives on liquid food only. They rely on human blood for their food.

Ans. True.
7. The alimentary canal stretches from mouth to anus.
8. What is rumen?
Ans. Rumen is the largest compartment of the stomach of a ruminant in which cellulose is broken down by the action of symbiotic microorganisms. The primary function of the rumen is as a storage compartment to facilitate microbial (bacterial and protozoal) fermentation of ingesta.
9. Which animals are called ruminant?
Ans. Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach, they have four. Of the four compartments, the rumen is the largest section and the main digestive centre.

The small finches on the Galapagos islands lived on islands with slightly different habitats. How did these varied habitats affect the evolution of the finches on different islands?
Adaptations - Darwin's Finches. Here are some adaptations of particular finches and the finches as a whole. ... The birds with bigger beaks survived, and the rest adapted by having developed strong and big beaks, or developed beaks that allow them to use tools to reach their food.
Hope it helps...
These varied habitats results in adaptive radiation which is responsible for evolution of the finches on different islands.
What is evolution?"Evolution is change in the heritable characteristics of biological populations over successive generations."What is adaptive radiation?"Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available."The small finches had to change its type of nutrient(eating seeds, small worms, etc.) in order to survive on the varied habitats of island. This results in their evolution.
Hence, adaptive radiation occurs due to varied habitats.

Describe & explain why the effect of temperature as a
limiting factor for photosynthesis is different to the
effects of Co2 and light intensity.
Answer:
Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes. As the enzymes approach their optimum temperatures the overall rate increases. It approximately doubles for every 10°C increase in temperature. Above the optimum temperature the rate begins to decrease, as enzymes are denatured, until it stops.
Explanation:
At low light intensities, as light intensity increases,the rate of the light-dependent reaction,and therefore photosynthesis generally, increases proportionately (straight line relationship). The more photons of light that fall on a leaf, the greater the number of chlorophyll molecules that are ionised and the more ATP and NADPH are generated. Lightdependent reactions use light energy and so are not affected by changes in temperature.As light intensity is increased further, however, the rate of photosynthesis is eventually limited by some other factor. So the rate plateaus. At very high light intensity, chlorophyll may be damaged and the rate drops steeply (not shown in the graph).Chlorophyll ais used in both photosystems. The wavelength of light is also important. PSI absorbs energy most efficiently at 700 nm and PSII at 680 nm. Light with a higher proportion of energy concentrated in these wavelengths will produce a higher rate of photosynthesis.An increase in the carbon dioxide concentrationincreases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor.As it is normally present in the atmosphere at very low concentrations (about 0.04%), increasing carbon dioxide concentration causes a rapid rise in the rate of photosynthesis, which eventually plateaus when the maximum rate of fixation is reached.

i) Describe the function of stomata.
Answer:
Stomata have two main functions, namely they allow for gas exchange acting as an entryway for carbon dioxide (CO2) and releasing the Oxygen (O2) that we breath. The other main function is regulating water movement through transpiration.
Explanation:
the main fiction of stomata is to open and close the pores in the leaves for an exchange of gases.
it allows the plants to take in carbondioxide and gives out oxygen for photosynthesis.
