(C) 100 kilocalories (Kcal) of energy is passed onto the secondary consumers when 10,000 kilocalories (Kcal) of energy is available for the producers.

According to the 10% rule, only 10% of the energy, that is available at a particular trophic level, is transferred to the succeeding trophic level. Since it is given that the amount of energy that is available to the producers is 10,000 kilocalories (Kcal), therefore, only 10% of this energy ,i.e. 1,000 kilocalories (Kcal) will be transferred to the primary consumers.

Similarly, only 100 kilocalories (Kcal) of energy would be transferred from the primary consumers to the secondary consumers.

The article "Peripheral blood mononuclear cell gene expression testing and the heterogeneity of T-cell-mediated drug reaction with eosinophilia and systemic symptoms syndrome" by Schmitz et al. discusses the use of gene expression testing in identifying the heterogeneity of T-cell-mediated drug reactions with eosinophilia and systemic symptoms (DRESS) syndrome.

DRESS syndrome is a severe and potentially life-threatening drug reaction characterized by skin rash, fever, and involvement of multiple organs. The pathogenesis of DRESS syndrome is thought to involve T-cell activation and proliferation in response to drug antigens.

The article suggests that gene expression testing of peripheral blood mononuclear cells (PBMCs) can help to identify the heterogeneity of DRESS syndrome, which may have important implications for diagnosis and treatment. The authors discuss a case study in which gene expression testing was used to identify differences in T-cell activation and cytokine expression in two patients with DRESS syndrome who were exposed to the same drug.

Overall, the article highlights the potential of gene expression testing in improving our understanding of the pathogenesis of DRESS syndrome and in identifying individual differences in immune responses to drugs. This may lead to more personalized approaches to diagnosis and treatment of DRESS syndrome in the future.

The correct answer is "The energy is transferred to ATP".

Explanation:

The missing information of this question is:

C6H1206 + 602 / 6CO2 + 6H2O + ATP

What happens to the energy in the bonds in glucose?

The energy is transferred to oxygen.

The energy is transferred to carbon dioxide.

The energy is transferred to water.

The energy is transferred to ATP.

The correct answer is "The energy is transferred to ATP".

During cellular respiration, the cell produces energy from the oxidation of glucose and it stores it in the form of adenosine triphosphate (ATP). The terminal phosphate group of ATP is highly energetic, and the cells breaks down ATP to use its energy in diverse chemical reactions. For this reason ATP is known as the "energy currency" or "coin of the cell".

The evolution of the cuticle in plants was a key adaptation to terrestrial living because it helps plants to avoid drying up.

Thus, the correct option is d. helps plant to avoid drying up.

In plants, the cuticle is a protective layer of waxy, hydrophobic substance produced by the epidermal cells. It is the layer of tissue that separates the aerial parts of the plant from the outside environment. It serves as a barrier to protect the plant from desiccation, UV radiation, and environmental stresses.The cuticle is thicker on leaves and shoots of plants that grow in dry environments, where the risk of water loss is greater.

The cuticle also helps to minimize water loss from the plant by limiting the amount of water that escapes from the plant's tissues by evaporation.Plants are considered the first organisms to live on land, and the evolution of the cuticle was a critical step in their transition from an aquatic to a terrestrial lifestyle. Without the cuticle, plants would have been unable to survive on land, as they would have dried out and died from desiccation.

The repolarization phase of the action potential sees the K+ ions leaving the cell and Na+ ions entering the cell through voltage-gated channels.

In the repolarization phase of the action potential, ions are the cell through voltage-gated channels. Na+ ions are going out of the cell, while K+ ions are going inside the cell. The depolarization phase begins when the Na+ ions move inside the cell, and the repolarization phase begins when the K+ ions move inside the cell. The depolarization phase happens when there is an opening of voltage-gated Na+ channels. The Na+ ions then rush into the cell, which causes it to become more positive. Then, there is the repolarization phase where there is an opening of voltage-gated K+ channels.

These channels are slow to open, but when they do, they allow K+ ions to flow out of the cell. This causes the cell to become more negative, which is called repolarization. The repolarization phase occurs immediately after depolarization, and it helps to restore the cell's original resting potential. In conclusion, the repolarization phase of the action potential sees the K+ ions leaving the cell and Na+ ions entering the cell through voltage-gated channels.

When we inhale, air enters through either our mouth or nose and travels down our windpipe or trachea.

From there, the trachea splits into two tubes called bronchi, which enter into our lungs. Once in the lungs, the bronchi split further into smaller tubes called bronchioles, which end in tiny air sacs called alveoli. It is at this point that the oxygen in the air we breathe is transferred into our bloodstream, while carbon dioxide is removed from our body.
The oxygen-rich blood then travels through the pulmonary veins to the left side of our heart, which pumps it out to the rest of our body through the arteries. The arteries then branch out into smaller blood vessels called capillaries, where the oxygen is delivered to our body's cells. The oxygen is used by our cells to produce energy, while the waste product of this process, carbon dioxide, is transported back to our lungs through our veins to be exhaled out of our body.

Anabolic pathways are the metabolic pathways that build molecules, while catabolic pathways break them down. These two pathways are opposing and require different enzymes for at least one of the steps. This is because the enzymes required for anabolic pathways are not suitable for catabolic pathways and vice versa.

Enzymes are highly specific, and they only catalyze specific reactions, which means that the same enzyme cannot be used for both anabolic and catabolic pathways.

For example, the enzyme hexokinase is used in the anabolic pathway of glucose synthesis, while glucose-6-phosphatase is required for the catabolic pathway of glucose breakdown.

Therefore, the opposing pathways need different enzymes to catalyze the specific reactions involved in each pathway.
To explain why opposing anabolic and catabolic pathways must have different enzymes for at least one of the steps:

Anabolic pathways involve the synthesis of complex molecules from simpler ones, requiring energy input. On the other hand, catabolic pathways involve the breakdown of complex molecules into simpler ones, releasing energy. Different enzymes are needed because these pathways have distinct functions and chemical reactions.

In conclusion, the opposing nature and specificities of anabolic and catabolic pathways require distinct enzymes for proper function and regulation.

The mean is greater than the median, the distribution of tail length is positively skewed. The median is more relevant in this case as it is not affected by the outliers.

The descriptive statistics of the data is shown below. Rounded to 2 decimal places:

Mean tail length: \(e. \bar{x}\) =95.50 mm4.

Median tail length: f. Q2=95.50 mm

IQR: Q3-Q1 = 12.50 mm

Variance: d. s²=46.80 mm²

SD: s=6.84 mm.

The mean is greater than the median of the tail length data. This implies that the data is positively skewed. This is because the mean is affected by outliers, which pulls it in the direction of the outliers. Hence, since the mean is greater than the median, the data is skewed towards the higher values.

The median measure is more relevant for this data because of the presence of outliers in the data, which has caused the mean to be influenced by the outliers, thus pulling it towards the higher side. So, the median will be more representative of the typical tail length of the population without being affected by the outliers. The mean, on the other hand, is an appropriate measure when the data is normally distributed, and there are no outliers in the data.

Explanation:

The synapse is an intercellular approach between neurons or between a neuron and a muscle or glandular effector cell. At the synapse, the transmission of the nerve impulse takes place. This is initiated by a chemical discharge that causes an electrical current in the membrane of the presynaptic cell (sending cell). Then, once this nerve impulse reaches the end of the axon (the connection with the other cell), the neuron secretes a chemical compound called neurotransmitter that is deposited in the cleft or synaptic space (intermediate space between this transmitting neuron and the postsynaptic or receiving neuron). These secreted substances or neurotransmitters (noradrenaline and acetylcholine among others) are responsible for exciting or inhibiting the action of the other cell called postsynaptic cell.
