ii) Explain briefly how these features contribute to the efficiency of photosynthesis?
Answers
Answer:
here's your answer
Explanation:
the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.
Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves
You are doing an experiment in which you are using an in vitro translation system derived from rabbit reticulocytes, called a rabbit reticulocyte lysate, to translate mRNA in a test tube. The rabbit reticulocyte lysate contains ribosomes, translation initiation and elongation factors, tRNAs, aminoacyl tRNA synthetases, release factors, amino acids, and ATP. The lysate does not contain any mRNA, so you must add the mRNA you would like to translate to the system. A. When you analyze the proteins made from your lysate, you find that they are all only two amino acids long. At first, you think that there must be a mutation to a stop codon in the position of the third codon, so you do another experiment with a different mRNA. Again, all the newly synthesized proteins are only two amino acids long, so you conclude that there is a problem with some component in your lysate.
Describe ONE possible problem in the translation system (lysate) that would result in the limitation of newly synthesized peptides to two amino acids in length.

Answer:
Problems with transfection efficiency or absence of essential mRNA modifications (capping and poly-A tail)
Explanation:
Translation is the process of protein synthesis from RNA in which the genetic information encoded in a messenger RNA (mRNA) molecule is translated into a protein sequence composed of amino acids. Translation has three steps: initiation, elongation, and termination. During translation, different elements are required to initiate, continue and complete the process, which include essential molecules such as amino acids, mRNA, tRNAs, ribosomes, energy-carrying molecules (i.e., ATP, GTP), initiation factors (i.e., eIF1A, eIF3, etc) and elongation factors (eEF-2, EIF5A). For example, humans can't synthesize nine essential amino acids (i.e., threonine, tryptophan, phenylalanine, valine, methionine, leucine, histidine, isoleucine, lysine), thereby it is imperative to include these amino acids to synthesize proteins composed of them. On the other hand, it is also fundamental to take into account that the efficiency of transfection of the molecules required during translation, as well as the absence of modifications in the mature mRNA sequence, may alter the process in vitro.

b. recharging the electron transport chain.
c. repaying an oxygen debt.
d. making more citric acid.
Answers
Answer:
The correct option is C.
repaying an oxygen debt.
Explanation:
This is because while running, humans breath shallowly which could not provide the oxygen requirement for the respiratory system and fit in for blood need.
After running, you tend to breathe heavily because your muscle work very hard , the body use more oxygen and produced more carbondioxide, therefore the lungs and respiratory system must try to provide more oxygen to the blood. sympathetic nerves stimulate respiratory muscles
so as to increase the rate at which we breathe.
Solve the problem, what are the genotypic and phenotypic ratios for this mating
• Rabbits have two different versions of eye colors (a trait for that organism). The two versions are white furred (one trait variation) which is the dominant allele and brown furred (the other trait variation) which is the recessive allele. You mate a homozygous individual with a homozygous recessive individual.
Answers
Determine the number of Punnett squares for each combination of alleles to get an idea of the genotypic-phenotypic ratio. This example uses one Punnett square for both RR and rr and two Punnett square boxes for Rr. The genotypic ratio can be calculated by dividing Punnett square ratios by 1:2:1.
What is a genotypic ratio?The genotypic ratio is a measure of how the genes are distributed among the progeny of a genetic cross, given as a ratio.The pattern of physical trait distribution in the offspring produced by a genetic cross is known as the phenotypic ratio, and it is stated as a ratio.To express the genotype and phenotype of offspring from a genetic cross, genotypic ratio and phenotypic ratio are the two types of genetic ratios used.It's possible that the genotypic and phenotypic ratios are not identical. Furthermore, based solely on phenotypic ratio, neither the genotypic ratio nor its distinction can be predicted or established. A genotypic ratio, however, may also be a sign of phenotypic ratio.According to Mendel's law of segregation, the genotypic ratio results. Two alleles separate in the progeny in accordance with Mendel's law of segregation, with one allele being inherited by half of the progeny and the other allele by the other half. The kids are not a perfect replica of their parents, according to this law.To Learn more About genotypic ratio Refer To:

A bacterial cell usually contains a single loop of DNA that is located in the cytoplasm of the cell and is not surrounded by a nuclear membrane. Some bacteria have additional loops of DNA called plasmids. Plasmids can be used for genetic engineering because DNA from other organisms can be spliced into a plasmid loop. For example, scientists in the late 20th century discovered a way to insert the portion of human DNA that codes for the protein insulin into plasmid E. coli bacteria. Which statement best explains why these genetically modified bacteria have been useful to society?
A. Human diabetics are now more resistant to bacteria
B. The bacteria are resistant to human diabetics
C. The bacteria can now make their own insulin
D. the bacteria are used to produce cheap insulin.
Answers
Answer: A is the correct answer.
because for the treatment of one type of diabetes insulin should be provided but isolation of insulin and production is so costly.
but as DNA recombination has developed we can use bacterial replication system to produce insulin. they replicate very fast so large amount of insulin will be produced and then it can isolated.
but we also know that insulin of bacteria needs some modification before it can be used in human.

Two test tubes labeled A and B
We set up another experiment in which we added the following enzymes:
Test Tube A = cellulase and Test Tube B = amylase. When the substrate
from the enzyme lab is added what would you expect to see happen in
each tube?
Answers
An enzyme-catalyzed reaction initially progresses at a faster pace as substrate concentration rises. This rise in rate of a reaction levels off as the substrate saturates the enzyme molecules.
An enzyme's concentration increases along with the speed of an enzyme-catalyzed process. The breakdown of the polysaccharide starch (amylose) into the disaccharide maltose is catalyzed by the enzyme amylase. Although it is easily abundant in saliva, obtaining high amounts might be uncomfortable. It is found throughout plant tissues, but it is most prevalent in seed, where that might play a role in starting the conversion of starch that has been stored into the much-needed glucose in enzyme-catalyzed process. The most prevalent organic polymer on earth is cellulose, a polysaccharide made up of a linear chain of 1,4-linked d-glucose subunits with such a degree of polymerization ranging from few hundreds to over ten thousand. An enzyme-catalyzed process is created when an enzyme binds to its substrate. This complex provides certain ions or chemicals groups that really establish chemical bond with molecule as a crucial stage of the reaction process, lowering the energy of activation and promoting its quick progression.
