We have learned that the response to selection is equal to the selection differential times the narrow-sense heritability (R = h^2 * S), where narrow-sense heritability includes only the additive genetic variance. The reason dominance genetic variance and gene interaction variance are not included is that they do not contribute to the genetic variation that is acted on by selection in the same way as additive genetic variance. So, only additive genetic variance is included in narrow-sense heritability, as it provides a reliable measure of the genetic variation that is consistently acted on by selection across generations.

Additive genetic variance directly contributes to the resemblance between parents and offspring, and therefore, it is an essential component for predicting the response to selection. In contrast, dominance genetic variance and gene interaction variance involve interactions between alleles at the same locus or between different loci, which can cause non-additive effects. These non-additive effects do not consistently transfer from one generation to the next, making them less predictable in terms of how they will affect future generations.
As a result, only additive genetic variance is included in narrow-sense heritability, as it provides a reliable measure of the genetic variation that is consistently acted on by selection across generations.

The structure in an ascomycete that is haploid is the ascus.

In ascomycetes, the ascus is the structure where sexual reproduction takes place. It contains the ascospores, which are the result of meiotic division. The ascus is formed from the fusion of two haploid nuclei, one from each parent, to form a diploid nucleus. This diploid nucleus then undergoes meiosis, resulting in the formation of haploid ascospores. These ascospores are the reproductive units that can be dispersed and give rise to new haploid individuals. Therefore, among the given options, the ascus is the structure that is haploid, as it contains the haploid ascospores. The basidium is a structure found in basidiomycetes, and the ascocarp is the fruiting body of an ascomycete, both of which are not haploid structures.

Coenzyme A (CoA) is a molecule that plays a vital role in metabolism, especially in the breakdown of fats and carbohydrates. To convert CoA to a high-energy form, it needs to be combined with acetic acid to form acetyl-CoA.

This reaction is catalyzed by the enzyme pyruvate dehydrogenase complex (PDC) and occurs during the oxidative decarboxylation of pyruvate in the mitochondria.

Acetyl-CoA is considered a high-energy molecule because it contains a thioester bond that has a high potential energy.

This bond can be hydrolyzed to release energy, which is used to power many metabolic processes in the cell, including the citric acid cycle and oxidative phosphorylation.

In summary, combining CoA with acetic acid to form acetyl-CoA is an important step in energy metabolism, and the resulting molecule is considered high energy due to its thioester bond.

The osmosis diagram is the one that most accurately represents how a plant cell might change in appearance after spending thirty minutes in a concentrated sugar solution.

Osmosis is the process by which water molecules move from an area with a lower concentration of solutes to an area with a higher concentration of solutes across a semi-permeable membrane.

If a concentrated sugar solution were present, the solute concentration outside the plant cell would be higher than that inside.

Water from inside the plant cell would naturally try to exit the cell as it is submerged in the concentrated sugar solution in an effort to balance the solute concentration on either side of the cell membrane.

The heat-stable DNA polymerase from a thermophilic bacterium, such as Taq polymerase, is used in the polymerase chain reaction (PCR) for several reasons:

1. Thermostability: Thermophilic bacteria, which thrive in high-temperature environments, have evolved enzymes that can withstand and function optimally at elevated temperatures. Taq polymerase, isolated from the bacterium Thermus aquaticus, is highly thermostable. It remains active even at the high temperatures (usually around 94-98°C) required for DNA denaturation in PCR. In contrast, DNA polymerases from E. coli or humans would denature at these temperatures, rendering them ineffective for PCR.

2. Temperature cycling: PCR involves repeated cycles of heating and cooling to denature the DNA strands, anneal primers, and extend them by polymerization. Taq polymerase can withstand these temperature fluctuations without losing its activity, making it suitable for the PCR process. Other DNA polymerases that are not heat-stable would be inactivated or degraded during the high-temperature denaturation steps of PCR.

3. Efficient DNA synthesis: Taq polymerase exhibits robust DNA synthesis activity and high processivity, meaning it can efficiently synthesize long DNA strands during PCR. This feature is crucial for the amplification of target DNA sequences. While DNA polymerases from E. coli or humans are capable of DNA synthesis, they may not perform as well as Taq polymerase in terms of efficiency and processivity.

4. Minimal contamination risk: Taq polymerase is typically purified from Thermus aquaticus, a bacterium that does not naturally inhabit the human body. Therefore, using Taq polymerase in PCR reduces the risk of contaminating the reaction with other DNA sequences, which could lead to false-positive results. In contrast, DNA polymerases from E. coli or humans may carry the risk of introducing additional DNA contaminants into the PCR reaction.

Overall, the choice of Taq polymerase in PCR is driven by its thermostability, resistance to high-temperature cycling, efficient DNA synthesis, and low contamination risk, all of which make it a reliable and widely used enzyme for DNA amplification in the PCR process.

The heat-stable DNA polymerase from a thermophilic bacterium, such as Taq polymerase, is used in the polymerase chain reaction (PCR) instead of DNA polymerase from: coli or humans because of its ability to withstand the high temperatures required during the PCR process. The correct option is (e).

PCR involves cycles of high-temperature denaturation, annealing, and extension. The denaturation step requires heating the DNA sample to separate the double-stranded DNA into single strands.

Then, during the annealing and extension steps, the DNA primers bind to the target sequences and the DNA polymerase synthesizes new DNA strands.

Taq polymerase, derived from the thermophilic bacterium Thermus aquaticus, is ideal for PCR due to its unique property of being highly heat-stable.

It can withstand the high temperatures (typically around 95°C) used for DNA denaturation without losing its enzymatic activity. In contrast, DNA polymerases from E. coli or humans are not heat-stable and would denature at these high temperatures, rendering them ineffective for PCR.

The use of Taq polymerase ensures that the DNA polymerase remains active throughout the PCR cycles, enabling efficient amplification of the target DNA.

This makes Taq polymerase a crucial component in PCR and has revolutionized various fields of research, diagnostics, and biotechnology.

Due to the presence of densely located buildings, the wind speed is reduced and the convective cooling effect is diminished.

These heat islands form because urban surfaces, such as roads and rooftops, absorb and emit heat to a greater extent than most natural surfaces. Heat reflected from a building is trapped by nearby taller buildings, known as the urban canopy. Cities with temperatures warmer than their surrounding natural environments are called urban heat islands. Man made materials, such as pavement, heat up quickly during the day. These surfaces radiate heat, which causes the air temperature around the city to rise. Trees, green roofs, and vegetation can help reduce urban heat island effects by shading building surfaces, deflecting radiation from the sun, and releasing moisture into the atmosphere.

An example of a compulsion is D) Constant and repetitive checking that the alarm is set.

Compulsions are repetitive behaviors or mental acts that individuals with certain mental health conditions, such as obsessive-compulsive disorder (OCD), feel driven to perform. These compulsions are often performed in response to obsessive thoughts or to alleviate anxiety or distress. Compulsions are typically not connected to the actual event or situation they are intended to address, but rather serve as a way to temporarily relieve anxiety or prevent perceived harm.

In the given example, constant and repetitive checking that the alarm is set is a classic example of a compulsion. The individual feels compelled to repeatedly check the alarm to ensure it is set, even though they may have already checked it multiple times before. This behavior is driven by an irrational fear or anxiety that something negative will happen if the alarm is not set correctly. The act of checking the alarm becomes a repetitive behavior intended to alleviate the anxiety associated with the fear.

It is important to note that anxiety about contracting HIV infection from a sneeze (A) and uncontrollable worry about an accident (B) are examples of obsessive thoughts or worries, which are often experienced in conjunction with compulsions in OCD. However, in the given options, they do not specifically represent compulsions.

The oxidation of 1 molecule of NADH by nitrate (NO3-) would yield approximately 4.3 ATP molecules per NADH molecule due to its reduction potential at 0.54 V.

The standard reduction potential of elemental sulfur (S) is at 0.04 V and therefore in the oxidation of 1 NADH molecule, it would synthesize around 1.2 ATP molecules per NADH molecule. The oxidation of NADH by ½ O2 molecule yields approximately 2.5 ATP molecules per NADH molecule due to the reduction potential of oxygen at 0.82 V.

The amount of ATP molecules generated from each of the terminal electron acceptors in NADH oxidation show the significant influence that the reduction potentials of the different terminal electron acceptors have on the amount of ATP the bacteria can synthesize.

Oxygen is not required for photosynthesis so we should just cross it out of the list. Secondly, the factors upon which photosynthesis depend are sunlight, carbon dioxide and temperature. So this also puts an end to water. As for carbon dioxide, if its amount is increased, the stomata of leaves will close and will not allow more of it to enter and thus process of photosynthesis will eventually decrease. And if we decrease the amount of carbon dioxide, plant will not be able to make its food properly.

An easy way to remember this is Pro sounds like NO, and EU sounds like DO.

The population after 40 years will be 400,000 animals, and the population after 65 years will be approximately 336,000 animals.

To determine the population after a certain time period, we can use the formula for exponential decay;

N(t) = N0 × \((1/2)^{(t/T)}\)

Where;

N(t) is the population at time t

N0 is the initial population

t is the time elapsed

T is the half-life of the population

Given;

N0 = 1.6 million

T = 20 years

Let's calculate the population after 40 years;

N(40) = 1.6 million × \(1/2^{(65/20)}\)

= 1.6 million × (1/2)²

= 1.6 million × (1/4)

= 400,000

Therefore, the population after 40 years will be 400,000 animals.

Now, let's calculate the population after 65 years;

N(65) = 1.6 million × \((1/2)^{(65/20)}\)

= 1.6 million × \((1/2)^{(13/4)}\)

≈ 1.6 million × 0.210

≈ 336,000

Therefore, the population after 65 years will be approximately 336,000 animals.
