Which of the following best supports the claim that binding of miRNA‑delta to the miRNA binding site inhibits translation of gene Q mRNA? When the miRNA binding site sequence is altered, translation of Q mRNA occurs in the presence of miRNA-delta.
The claim that binding of miRNA-delta to the miRNA binding site inhibits translation of gene Q mRNA is supported by the observation that altering the miRNA binding site sequence allows translation of Q mRNA to occur in the presence of miRNA-delta.
MiRNAs are small RNA molecules that play a role in gene regulation by binding to specific sequences in mRNA molecules, leading to translational repression. The binding of miRNA-delta to the miRNA binding site of gene Q mRNA suggests that miRNA-delta is targeting and interacting with this specific mRNA molecule. This binding likely interferes with the translation process, preventing the synthesis of the protein encoded by gene Q.
This inhibitory effect is supported by the observation that when the sequence of the miRNA binding site is altered, translation of Q mRNA occurs even in the presence of miRNA-delta.
This suggests that the altered sequence no longer allows effective binding and interaction between miRNA-delta and gene Q mRNA, allowing translation to proceed.

Assuming 100% efficiency of energy conservation, how many moles of ATP can be synthesized under standard conditions by the complete oxidation of 1 mol of glucose?
The complete oxidation of 1 mole of glucose under standard conditions can yield a maximum of 38 moles of ATP assuming 100% efficiency of energy conservation.
In cellular respiration, glucose is broken down through a series of metabolic reactions, including glycolysis, the Krebs cycle (also known as the citric acid cycle or TCA cycle), and oxidative phosphorylation. These processes result in the production of ATP.
During glycolysis, 2 moles of ATP are generated directly through substrate-level phosphorylation. The subsequent steps in the Krebs cycle produce high-energy carriers in the form of NADH and FADH2.
These carriers, along with oxygen, are used in the electron transport chain (part of oxidative phosphorylation) to generate ATP through oxidative phosphorylation. Each NADH molecule can generate approximately 2.5-3 moles of ATP, while each FADH2 molecule can produce approximately 1.5-2 moles of ATP.
Considering the stoichiometry and energy yield of these processes, it is estimated that, on average, the complete oxidation of 1 mole of glucose can yield a net total of approximately 36-38 moles of ATP under standard conditions if energy conservation is 100% efficient.

if glucagon binds to surface receptors on liver cells to send an intracellular message for glycogen breakdown, this process is known as which mechanism of action?
The process described, where glucagon binds to surface receptors on liver cells to initiate intracellular signaling for glycogen breakdown, is known as the second messenger mechanism of action.
The second messenger mechanism of action is a common signaling pathway utilized by various hormones and neurotransmitters. It involves the activation of cell surface receptors, such as G protein-coupled receptors (GPCRs), by the binding of a ligand (in this case, glucagon). Once the ligand binds to the receptor on the cell surface, it triggers a series of intracellular events that ultimately lead to a cellular response.
In the case of glucagon signaling in liver cells, upon binding to the receptor, the GPCR undergoes conformational changes and activates intracellular G proteins. These G proteins then trigger the production or release of second messengers, such as cyclic AMP (cAMP), which serve as signaling molecules within the cell. The second messengers propagate the signal and activate downstream signaling pathways, ultimately resulting in glycogen breakdown in the liver.
Therefore, the mechanism of action described, where glucagon binds to surface receptors on liver cells to initiate intracellular signaling for glycogen breakdown, is known as the second messenger mechanism of action.

in meiosis the spermatozoa that are produced are genetically unlike each other and unlike the cell that produces them. this is one reason for the great variation among humans. what causes this effect?
The genetic diversity among humans is attributed to the process of meiosis, where spermatozoa are produced with genetic differences both among themselves and the cell that produces them.
Meiosis is a specialized cell division process that occurs in the testes (in males) and ovaries (in females) to produce gametes (sperm and eggs) with half the number of chromosomes compared to other body cells. During meiosis, two rounds of cell division take place: meiosis I and meiosis II.
In meiosis I, homologous chromosomes pair up and exchange genetic material through a process called genetic recombination or crossing over. This exchange of genetic material between the paired chromosomes creates new combinations of genes, leading to genetic diversity. The homologous chromosomes then separate, resulting in two daughter cells with half the number of chromosomes.
In meiosis II, the two daughter cells from meiosis I undergo another round of division without replicating their DNA. This separation process further shuffles the genetic material, leading to additional variation.
The end result is the production of spermatozoa (sperm cells) that carry unique combinations of genes, different from one another and from the cell that initially underwent meiosis. This genetic variation contributes to the diversity observed among humans.

A virus that kills its host is said to beA) lytic or virulent.B) temperate.C) lysogenic.D) virulent or lysogenic, but not temperate.
A virus that kills its host is said to be lytic or virulent. This type of virus rapidly infects and reproduces inside the host cell, ultimately causing the cell to burst and die, releasing new viral particles into the host organism. The lytic cycle is the preferred pathway for many viruses, as it allows them to spread quickly and efficiently to new hosts. In contrast, temperate viruses can integrate their DNA into the host cell's genome and remain dormant for long periods of time, potentially becoming active again in the future.
Lysogenic viruses also integrate into the host genome but do not necessarily kill the host cell. Overall, the lytic cycle is the most destructive to the host organism and is characterized by the rapid replication and unit of infected cells.

Aposematic, or warning, coloration in poison frogs was found by Juan Santos and colleagues to be polyphyletic. What does this indicate about aposematic coloration?
It arose in the common ancestor of these frogs.
It is homologous.
It is the result of convergent evolution.
It is an exaptation.
The finding that aposematic coloration in poison frogs is polyphyletic indicates that it is the result of convergent evolution.
Convergent evolution refers to the independent evolution of similar traits or characteristics in different lineages that do not share a recent common ancestor. In the case of aposematic coloration in poison frogs, the polyphyletic nature of this trait suggests that it has evolved multiple times in different lineages of frogs. It is not a shared ancestral trait that arose in a common ancestor.
Instead, different frog lineages have independently evolved similar warning coloration as a means of advertising their toxicity to potential predators. This convergence in coloration is driven by natural selection, as predators learn to associate bright and conspicuous colors with toxicity and avoid consuming these frogs.
