If structure E (stapes) lost flexibility, it would impair sound transmission, leading to hearing sensitivity.

Process of hearing: Sound waves enter the ear, vibrate the eardrum (tympanic membrane). Ossicles (A: malleus, B: incus) amplify vibrations to inner ear. Vibration of fluid in cochlea stimulates hair cells, converting to electrical signals for interpretation.

Structure A: Malleus

Structure B: Incus

(a) Structure C (eustachian tube) equalizes pressure on both sides of the tympanic membrane.

(b) Structure D (round window) absorbs excess pressure waves from the inner ear.

Hearing involves a process of sound wave transduction through the tympanic membrane and ossicles. If the tympanic membrane (E) loses its flexibility, sound quality may diminish. The Eustachian tube and cochlea serve to manage pressure within the ear.

The process of hearing (audition) involves the transduction of sound waves into a neural signal. When the tympanic membrane (structure E in your diagram), or eardrum, is struck by sound waves, it vibrates. These vibrations are then transferred to the ossicles, which are three small bones in the middle ear. The ossicles are identified as structures A (Malleus or Hammer) and B (Incus or Anvil) in your diagram. Sound waves are finally transduced into a neural signal in the inner ear.

If the tympanic membrane was to lose its flexibility, it would not vibrate as effectively when struck by sound waves. This could diminish the quality of sound and potentially lead to hearing loss.

The Eustachian tube equilibrates air pressure on both sides of the tympanic membrane. This would be your answer to part (a) of the lettered question. Part (b) refers to the role of the cochlea in the inner ear, which helps to absorb excess pressure waves from the inner ear.

Explanation:

Photosynthesis and cellular respiration are two close related and complementary processes. Photosynthesis produces organic molecules and releases oxygen, which are used during cellular respiration to produce water, ATP, and CO₂.

Photosynthesis is a process plant cells go through when absorbing sunlight.

During photosynthesis, light energy and inorganic compounds are used to produce organic compounds -glucose- and release oxygen.

It occurs in chloroplasts and involves two stages: light-dependent and light-independent reactions.

• During light-dependent reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions. It occurs in the thylakoid membrane in the electron transporter chain.

• The light-independent reaction occurs in the Calvin cycle in the stroma. During this stage, carbon from CO2 is fixated, and sugar molecules are synthesized

Cellular respiration is the process through which cells use organic compounds to produce energy.

Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

1. Occurs in the presence of free oxygen.

2. Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.

3. Respiration occurs in the mitochondria.

4. Takes place in two steps or stages: Krebs cycle and electron transporter chain.

5. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.

1. Occurs in the absence of free oxygen

2. Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.

3. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.

4. Lactic fermentation produces lactic acid and 2 ATP

5. Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂

6. The whole anaerobic process occurs outside the mitochondria.

Photosynthesis is complementary to cellular respiration.

Here are four traits that would make it hard for a vaccine to be used:

1. Rapid mutation rate. If a pathogen mutates rapidly, it will be able to evade the immune system's defenses, including the antibodies produced by a vaccine. This is a particular problem with viruses, which can mutate very quickly.

2. Ability to evade the immune system. Some pathogens are able to evade the immune system by hiding inside cells or by changing their surface proteins so that they are no longer recognized by the immune system. This makes it difficult for the immune system to mount an effective response to the infection.

3. Ability to spread easily. If a pathogen is easily spread from person to person, it will be more difficult to prevent infection through vaccination. This is a particular problem with respiratory viruses, which can be spread through coughing and sneezing.

4. Lack of animal reservoirs. If a pathogen does not have animal reservoirs, it will be more difficult to develop a vaccine against it. This is because vaccines are typically developed using weakened or killed versions of the pathogen. If there are no animal reservoirs, there will be no source of the pathogen to use for vaccine development.

It is important to note that these are just a few of the traits that can make it difficult to develop a vaccine against a pathogen. There are many other factors that can contribute to the difficulty of vaccine development, such as the cost of vaccine development, the availability of funding, and the political will to support vaccine development.

Answer:uracil, hydrophilic

Explanation:

A) Two ways of measuring biodiversity:

Species Richness: Species richness refers to the number of different species present in a particular area or ecosystem.

Species Evenness: Species evenness measures the relative abundance of different species within an ecosystem. It examines the distribution and balance of individuals among species.

Relationship between biodiversity and ecosystem stability: Biodiversity is closely linked to ecosystem stability. A higher level of biodiversity generally enhances the stability of an ecosystem, making it more resilient to disturbances and environmental changes. This relationship can be attributed to factors like Redundancy and Complementary Interactions.

Evidence from susceptibility to disease in agricultural crops and isolated tribal populations:

The susceptibility to disease in both agricultural crops and isolated tribal human populations can provide evidence supporting the importance of biodiversity for ecosystem stability.

In agricultural crops, monocultures (the cultivation of a single crop) with low biodiversity are more vulnerable to disease outbreaks. When a single crop dominates a large area, pests and diseases can easily spread, causing significant losses.

Similarly, isolated tribal human populations with limited genetic diversity often face higher susceptibility to diseases. Due to their isolation and limited gene pool, these populations may lack genetic variation and adaptive potential to resist novel diseases.

B) Hypothesis about the effects of biodiversity on an ecosystem's reaction to adverse conditions such as drought:

Hypothesis: Ecosystems with higher levels of biodiversity will exhibit greater resilience and recovery in response to adverse conditions such as drought compared to ecosystems with lower levels of biodiversity.

C) Experiment to test the hypothesis:

Overall Investigation: The experiment aims to compare the response of two ecosystems, one with high biodiversity and the other with low biodiversity, to drought conditions.

Variables to be changed:

Biodiversity level: Two study sites with contrasting levels of biodiversity will be selected, one representing high biodiversity and the other representing low biodiversity.

Variables to be kept constant:

Environmental conditions: Ensure that environmental factors, such as temperature, sunlight exposure, and soil type, are similar for both study sites.

Subjects to be used:

Select two similar ecosystems (grasslands, forests) with contrasting levels of biodiversity.

Control and Experimental Conditions:

Control: Ecosystem with low biodiversity (monoculture or simplified community)

Experimental: Ecosystem with high biodiversity (diverse plant and animal species)

Type of data collected:

Vegetation data: Monitor changes in plant species composition, density, and growth rates in response to drought.

Animal data: Record species diversity, abundance, and behavior of animals in both ecosystems.

Data collection method:

Data will be collected through field observations, vegetation sampling, animal surveys, and soil sampling. The data can be analyzed using statistical methods to compare the responses of the two ecosystems to drought.

Justification for drawing a conclusion:

By comparing the responses of high-biodiversity and low-biodiversity ecosystems to drought conditions, the data collected will provide insights into the relationship between biodiversity and ecosystem resilience.

Statistical analysis can help determine whether ecosystems with higher biodiversity exhibit greater stability and recovery in the face of adverse conditions like drought.

D) Changes to the biodiversity of the surviving ecosystem fragment and its stability over the next few years when insect pests move in:

The wildfire that wiped out most of the forest would result in a significant decrease in biodiversity within the surviving patch. The plant species diversity would be greatly reduced, and some specialized or rare species might be lost completely.

The surviving ecosystem fragment would experience a bottleneck event, leading to reduced genetic diversity among the remaining plant species.

As insect pests move into the patch, the reduced biodiversity and genetic diversity would make the ecosystem fragment more vulnerable to their impact.

With limited species and genetic variation, the surviving plants would have fewer natural defenses against pest outbreaks.

The reduced biodiversity and genetic diversity in the ecosystem fragment would limit the capacity of the remaining plants to adapt to the pests' presence.

Without the buffering effect of diverse species interactions and genetic variability, the ecosystem fragment may struggle to maintain ecological balance and may experience more significant disruptions in ecological processes.

It will reduce the cost and energy used to treat the water

Explanation:

Water conservation can help control water pollution by reducing the amount of water that needs to be treated and processed. When less water is used, less polluted water is generated from households, industries, and agricultural activities.

Water conservation reduces the amount of wastewater that needs to be treated and discharged into natural water bodies, such as rivers and lakes. Additionally, conservation measures such as using low-flow fixtures, fixing leaks, and reducing water-intensive activities can help reduce the amount of energy needed to treat and transport water, which also reduces the carbon footprint and associated pollution from energy generation. Overall, water conservation is an effective way to reduce the demand for water resources and minimize the pollution that results from water use and treatment.

Hence, water conservation can help control water pollution by reducing the amount of water that needs to be treated and processed. When less water is used, less polluted water is generated from households, industries, and agricultural activities.
