Answer:
Glycolysis yields 2 molecules of ATP, while the electron transport chain yields 32 molecules of ATP due to the presence of oxygen.
Explanation:
Glycolysis yields 2 molecules of ATP, while the electron transport chain yields 32 molecules of ATP due to the presence of oxygen.
What is electron transport chain?An electron transport chain is a collection of protein complexes and other molecules that associate protons across a membrane with the transfer of electrons from electron donors to electron acceptors via redox processes. Both photosynthesis and cellular respiration take place in mitochondria.
An organic metabolite (an intermediary in metabolic reactions) reacts with the coenzyme NAD+ to begin the electron transport cycle (nicotinamide adenine dinucleotide). In this oxidation reaction, the organic metabolite loses two hydrogen atoms (or two hydrogen ions and two electrons).

Which step in the Gram stain is the critical step in differentiating Gram negative cells from Gram positive cells?
Answer:
The rapid decolorization with ethanol or acetone
and counterstaining with safranin
When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple

Which is common to the life cycles of both flowering and non-flowering plants?
Answer:
Explanation:
Nonflowering plants include ferns, mosses, mushrooms, and many trees. It's obvious nonflowering plants are different from flowering plants because they don't have flowers, but there is also a difference in how they reproduce. While flowering plants only use seeds, nonflowering plants use either seeds or spores.

How was osmosis used to stop Clark's seizures?
Answer:
after Clark was treated with a hypertonic solution? increased Na concentration in matrix of brain caused water from blood to move in to the brain which increased the matrix pressure. Pressure caused the neuron firing rate to increase which increased the likelihood of seizures.

Grabbing a handful of mixed candy out of a bowl.
Explanation:
For all other options you are choosing specific items... such as a book from the library, or choosing items written on your grocery list, or choosing what to pack for lunch. Bycatch in fishing refers to catching extra fish, other than what you are selecting for. By grabbing a handful of mixed candy from a bowl you are not selecting for a specific 'fish'.
Place the steps of constructing a genomic library in order. I. Digest phage with restriction enzyme. II. Lyse cells of interest and precipitate DNA. III. Introduce constructs via transformation into competent E. coli cells. IV. Perform ligation reaction with genome fragments and phage. V. Digest genomic DNA with restriction enzyme.g
Answer:
The correct answer is -
II: lyse cells of interest, precipitate DNA
V. Digest (cut) genomic DNA with restriction enzyme
I. Digest (cut) phage (chromosome) with restriction enzyme so can ligate in the gene in next step!!
IV. Perform ligation (glue plasmid in!) reaction with genome fragments and phage.
III Introduce constructs via transformation into competent E. coli cells.
Explanation:
The total collection of the genomic DNA of an organism is known as the genomic library of the particular organism. In this library, the genomic DNA is inserted and stored in identical vectors.
The genomic library construction involved some major steps that are:
- Extract and purify DNA - lysing and separating the desired DNA of interest.
- Digest the DNA with a restriction enzyme - breaking or digesting DNA into fragments with restriction enzymes
- cut phage (chromosome) with restriction enzyme
- Insert the fragments of DNA into vectors
- introduce these recombinant a host bacterium by transformation, creating a DNA library.

Answer:
it says that plants are the main source of nutrients and energetic materials and when the cow feed on them, it consumes some of the benefits that we miss when we eat beef
Answer:
Question 6: The answer is the energy, because it collects more energy than the cow. When the cow eats plants, the energy from the plant decreases leaving the cow with only little amount.
Question 7: I agree, Because plants holds way more nutrients and energy than meat. I could support that by saying when a herbivore eats from a plant, It only recieves 10%.

how do the structures of a vacuole and a nucleus differ?
A. a vacuole is enclosed within a membrane ,and a nucleus is not enclosed within a membrane.
B. a vacuole is thick fluid , and nucleus is rigid set layers
C. a vacuole contain no water , and a nucleus a mostly water
D. a vacuole contain mostly water, and a nucleus contain mostly DNA
Answer:
D
Explanation:
Vacuoles are pockets that collect water and the cell's junk. The nucleus sends commands to other cell parts and contains DNA.
Why it isn't A: Both have membranes.
Vacuole- tonoplast. Nucleus- Nuclear membran.
Why it isn't B: The Vacuole is not a thick fluid, though it may hold thick fluid.
Why it isn't C: This should be obvious.
Like replication and transcription, translation is a process in which the information present within a nucleic acid template is used to guide the synthesis of a new polymer. But the translation machinery is much more complex than the machinery involved in replication or transcription. Discuss the aspects of translation that make it so challenging for the cell.
Answer:
The aspect of translation that makes it so challenging for the cell is that it involves too many steps and too many molecules and organelles. mRNA associated with rRNA and tRNA. rRNA reading mRNA in a specific direction. Codon sequences indicating where to start and where to finish the synthesis. Different codons codifying for different aminoacids and tRNA recognizing those codons to add the correct amino acid to the chain. If the protein is destined to exportation, RER and Golgi complex are also involved in the process.
Explanation:
In protein synthesis, the first step is to synthesize messenger RNA, mRNA. The transcription is the coping process of the DNA section, and it happens in the nucleus. After that, the translation occurs when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.
Once in the cytoplasm, it begins the translation process. mRNA meets a free ribosome, which is the primary structure for protein synthesis. Ribosomes are composed of two subunits, a big one and a small one. They also associate with different tRNA that carrying amino acids. Ribosomes might be floating freely in the cytoplasm or can be attached to the rough endoplasmic reticulum.
The ribosome reads mRNA in the 5´ to 3´ direction, and, according to the codons that are being readen, tRNA transfers the correct amino acids to build the polypeptide chain. Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA. Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid. tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.
Once the new amino acid links to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.
The protein is synthesized from the amino terminus to the carboxy terminus, while the added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches the end codon, protein synthesis is over.
And if the protein is destined for exportation or cell membrane, its synthesis also involved organelles like the Rough endoplasmic reticulum and the Golgi complex.
A woman and her baby are on a TV talk show to determine whether or not a particular man is the father of the child. Mom is blood type O and the baby is blood type B. The potential dad is blood type A. Is it true or false that he is the father?
Answer:
No that is not the father
Explanation:
The fathers blood would have to be type B. Type A is dominate to O and co-dominate to B so you get AB blood, type B blood is dominate to O blood. So if the mom has to be OO to show O blood and the father has to be AA blood because he isn't AB or AO, which could make the baby AO or OO blood. Since none of this is true the "TRUE" father would have to have AB, BB, or Bo blood.
