Starting with pyruvate to make acetyl-CoA and continuing into the citric acid cycle, and oxidative phosphorylation, how many ATP can be made from 1 molecule of pyruvate
Answer:
The correct answer is - 15 ATPs.
Explanation:
Cellular respiration (aerobic) is the process that involves glycolysis, oxidative decarboxylation, citric acid cycle and oxidative phosphorylation or ETS to breakdown one molecule of glucose in order to generate energy in ATPs. Pyrivate is the end product of glycolysis and it is go to form acetyl CoA.
One molecule of pyruvate genrates 1 molecule of FADH2, four molecules of NADH, and 1 molecule of ATP during oxidative decarboxylation and citric acd cycle. During the oxidation in the electron transport system there is 4 molecules of NADH2, 1 molecule of FADH2, and 12 (4×3) ATP molecules, respectively by oxidation in the electron transport system (ETS).
Thus, there would be 15 molecules of ATPs produce by one molecule of pyruvate.

Single Strand Binding Proteins are responsible for:
A. keeping the strands separated during replication.
B. unwinding and separating the DNA strands.
C. adding the new bases.
D. linking the short sections of the lagging side.
Reset Selection
Answer:
A. keeping the strands separated during replication
Explanation:
Prior to the process of DNA replication, the double-stranded DNA must first be separated into single strands by an enzyme called DNA helicase. This is done so that each DNA strand can serve as template for the synthesis of another.
After the unwinding and separation, the single strands still need to be kept apart during the synthesis of new nucleotides by DNA polymerase. This role of keeping the strands separated during replication is carried out by SINGLE STRAND BINDING PROTEINS.
Which type of plate boundary would be most likely to lead to above-ground volcanic activity?
A . Subduction
B .divergent
C.collisional
D . Transform
Answer:
A.Subduction
Explanation:
In a subduction zone, one plate slides beneath another. This leads to friction that can melt the crust and result in volcanic activity
The following illustration shows a food web for a kelp forest off of the coast of California. What do you predict would happen to the kelp population if the sea otter population declined?
The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
The kelp population would increase: sea otters eat urchins, but not exclusively.
The kelp population would remain unchanged; sea otters do not eat the kelp.
The kelp population would remain unchanged: sea otters eat urchins, but not exclusively.
Answer:
The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
Explanation:
The diagrammatic illustration in this question is showing a food web made up of a variety of species feeding on one another. As shown in the food web, sea otters are one of the top predators that can eat a wide variety of organisms.
Sea urchins feed directly on kelp, however, the population of sea urchins can be controlled by sea otters which feed on sea urchins. Hence, if population of sea otters declined, more sea urchins will be available to feed on the kelp population, hence, will DECREASE.
Answer:The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.
Because the otter population decreases the urchin population increases and therefore the demand for kelp increases and the kelp population will decrease as the population of urchins increases and it feeds on the kelp and due to the reduction in otters there is nothing controlling the urchin population

Answer:
a) mRNA before mutation ⇒ CAG
b) mRNA after mutation ⇒ CAC
c) amino acid before mutation ⇒ Glu, Glutamine
d) amino acid after mutation ⇒ His, Histidine
e) missense mutation
Explanation:
Theoretical frame
Transcription:Transcription occurs in the nucleus where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.
When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.
The coding strand goes in direction 5´ to 3´, while the complementary strand -template strand- grows in direction 3´ to 5´.
The template strand is the mRNA complement.
The coding strand is the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.
The coding strand receives that name because it is the sequence that codes for each amino acid composing the proteins.
Translation:Translation occurs in the cytoplasm. rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are 64 codons in total, from which 61 codify for amino acids. Because there are 20 amino acids, many codons code for the same amino acid. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.
The codons indicating the initiation or stop points during the translation process are:
• The start codon AUG is the most common sequence used by eukaryotic cells
• The end codons are UAA, UAG, UGA.
When a change occurs in a single base pair, it is known as a point mutation. Points mutations might be either silent, missense, or nonsense. In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence. However, if the mutation causes the mRNA codon to code for a different amino acid, this mutation is a missense mutation. Finally, if the mutation causes mRNA codon to be a stop codon, we are referring to a nonsense mutation.
----------------------------------------------------------------------------------------------------------
In the exposed example,
Before mutation
Original DNI base sequence ⇒ GTC ⇒ Guanine, Timine, CytokineTranscripted mRNA sequence ⇒ CAG ⇒ Cytokine, Adenine, GuanineAmino acid ⇒ Gln ⇒ GlutamineAfter mutation
Mutated DNI base sequence ⇒ GTG ⇒ Guanine, Timine, GuanineTranscripted mRNA sequence ⇒ CAC ⇒ Cytokine, Adenine, CytokineAmino acid ⇒ His ⇒ HistidineThis is a point mutation, in which the change occurs in a single base pair. The mutation made the mRNA codon code for a different amino acid, meaning that this is a missense mutation.
Before mutation, the mRNA codon is CAG and codes for Glutamine.After mutation, the mRNA codon is CAC and codes for Histidine.All cells are contained within a membrane called the:

II. Isolate the genes from the specialist cell.
III. Select the desired trait.
IV. Insert the genes into the target organism.
What is genetic engineering?Genetic engineering (also named genetic modification) exists as a system that operates laboratory-based technologies to change the DNA makeup of an organism. This may influence changing a single base pair (A-T or C-G), deleting a region of DNA, or adding a unique element of DNA.
Genetic engineers change, splice, eliminate, and rearrange genes to change an organism or classes of organisms. Genetic engineering, also called genetic modification or genetic manipulation exists in the modification and manipulation of an organism's genes operating technology.
Genetic engineering stands performed in three fundamental steps. These exist,
(1) The isolation of DNA components from a donor organism.
(2) The insertion of an isolated donor DNA fragment into a vector genome.
(3) The effect of a recombinant vector in a suitable host.
Hence, The accurate order is,
I. Replicate the new organism.
II. Isolate the genes from the specialist cell.
III. Select the desired trait.
IV. Insert the genes into the target organism.
Thus, Option C is correct.

Jim has become particularly interested in the genetic basis of cancer and has spent considerable time reading published papers about oncogenes. He learned that as early as 1972 researchers suggested that mutations in proto-oncogenes caused by carcinogens can convert them to oncogenes. He asked you to answer a couple of questions about this because he did not have the biology background to totally understand. Jim learned that some cancer cells produce more growth-stimulating proteins than others. What would you give him as a plausible explanation
Answer:
Proto-oncogenes may have mutated to become oncogenes in these cells
Explanation:
Cancer cells are characterized by key properties such as an abnormally rapid rate and poor differentiation. Proto-oncogenes are genes that lead normal cells to become cancer cells when they are mutated. Many proto-oncogenes are involved in the control and progression of the cell cycle, and apoptosis (programmed cell death) pathway. Some examples of protooncogenes include 1-the Ras gene, which is required for differentiation, growth, and cell survival (mutations of this gene have been reported in pancreatic cancer, lung cancer, colon cancer and thyroid cancer), 2-the Myc gene (mutated in Burkitt's lymphoma), 3- the Her2 receptor (a receptor kinase associated with breast cancer), etc.

The teacher was unaware of the difference between suspension feeding and predation. The teacher thought that providing live copepods (2 mm long) and feeder fish (2 cm long) would satisfy the dietary needs of all of the organisms. Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)
Answer:
The correct answer is - Biwalves and sponges.
Explanation:
Suspension feeders are the organisms that depend on, for the dietary needs or nutriton, materials suspended in the water. The materials that are suspended are living organisms such as phytoplankton and zooplankton.
Biwalves and sponges are suspended or filter feeders and not predators like other organisms so providing copepods will not complete their food requirement and they will starve to death.
The correct answer is - Biwalves and sponges.

Un tractor tira de un remolque cargado sobre un camino plano libre de fricción, con una fuerza horizontal constante de 440 N. Si la masa total del remolque y su contenido es de 275 kg, ¿Qué aceleración tiene el remolque? Formula a utilizar : Ʃ F = m . A *
Answer:
1,6 m / s ^ 2
Explanation:
De las leyes de Newton;
Fuerza = masa × aceleración
masa = 275 kg
Fuerza = 440 N
Aceleración = Fuerza / masa
Aceleración = 440N / 275Kg
Aceleración = 1,6 m / s ^ 2
