Answer:

The trophic efficiency between the primary and the secondary produces is 18.064 %

Explanation:

The trophic efficiency is the ratio or the fraction obtained by dividing the energy used for growth at a trophc level by the level of energy supplied at the the next lower trophic level.

The given parameters are;

The energy produced by the bacteria (primary consumer) = 173,000 kJ/(m²/y)

The energy contained in the plankton = 28,000 kJ/(m²/y)

The energy contained in the shrimp = 3,100 kJ/(m²/y)

The energy contained in the herring = 150 kJ/(m²/y)

Therefore, we have;

Energy supplied at the primary trophic level = 173,000 kJ/(m²/y)

The energy used for growth (contained) in the secondary trophic level (secondary consumer)  = 28,000 + 3,100 + 150 =  31,250 kJ/(m²/y)

\(Trophic \ efficiency = \dfrac{Energy \ used \ for\ growth\ (Secondary\ consumer) }{ Energy \ Supplied \ (Primary \ consumer) } \times 100\)

\(Trophic \ efficiency = \dfrac{31,250}{ 173,000} \times 100 = 18.064 \ \%\)

In most cases, phenotypic variance mixes environmental and genotypic variance. There are three main types of genetic variance: additive genetic variance, dominance variance, and epistatic variance. The inheritance of a specific allele from a parent and this allele's independent impact on a particular phenotypic are both examples of additive genetic variance, which results in a departure of the phenotype from the mean phenotype. The phenotype variation brought on by interactions between different alleles controlling the same trait at a single locus is referred to as dominance genetic variance. Different alleles at various loci interact to produce epistatic variation.

Answer:

Capillary reabsorption does not depend on oncotic pressure

Explanation:

Edema refers to the swelling caused by the fluids trapped in the body's tissues, which swell from injury and/or inflammation. Edema can be associated with the decrease in plasma oncotic pressure, i.e., osmotic pressure exerted by proteins (especially albumin) in the blood vessel's plasma, the increase in hydrostatic pressure, or the increase in the capillary permeability. Moreover, capillary reabsorption refers to the movement of fluid from interstitial space to the capillaries, which is driven by the blood colloidal osmotic pressure. Lymphatic obstruction, i.e., the blockage of the lymph vessels that drain fluids from tissues, may cause edema in the part that is drained by the affected vessels (it is known as lymphedema). Moreover, liver/kidney failure may lead to edema by decreasing albumin and oncotic pressure. When plasma albumin levels drop because of liver diseases, the colloid osmotic pressure also decreases. In consequence, liver diseases, including stage 3 cirrhosis, lead to the development of swelling in the abdomen, thereby leading to edema.

When there is an increase in water volume in plasma, it causes the hydrostatic pressure in plasma to increase and the osmotic pressure to decrease and as a result, water will move out of plasma.

When water volume in plasma increases, the hydrostatic pressure will increase.

Increase in water volume will result in a decrease in the osmotic pressure of plasma due to dilution of the solutes in plasma.

Therefore, to maintain homeostasis, water will move out of the plasma by simple diffusion and osmosis.

Therefore, increased water volume causes the hydrostatic pressure in plasma to increase and the osmotic pressure to decrease and as a result, water will move out of plasma.

Photorespiration rate is minimized by ensuring that RubisCO always encounters high CO2 concentrations which are accomplished by two pathways: the C₄ pathway and the CAM pathway.

The C₄ pathway involves the formation of an unstable four-carbon acid in the mesophyll cells which is then converted to a three-carbon acid in bundle sheath cells. This process of forming the four-carbon acid is called "C₄ carboxylation" and it allows for the CO₂ to be more concentrated in the bundle sheath cells. This increases the efficiency of RubisCO and reduces the rate of photorespiration.

The CAM pathway involves the opening of the stomata at night when temperatures and light levels are lower. This process allows the plant to take in CO₂ and store it as malic acid until the next day. This process increases the concentration of CO₂ available to Rubisco and reduces the rate of photorespiration.

In conclusion, the two pathways that minimize photorespiration rate by ensuring that RubisCO always encounters high CO₂ concentrations are the C₄ pathway and the CAM pathway.

Antiseptics and disinfectants are both used to control the growth of harmful microorganisms, but they differ in their applications and chemical properties.

Antiseptics are substances that inhibit the growth of bacteria and other microorganisms on living tissues. They are primarily used to prevent infections in wounds, cuts, and abrasions. Examples of antiseptics include hydrogen peroxide, iodine, and alcohol-based solutions such as ethyl alcohol and isopropyl alcohol. These solutions are gentle enough to be applied directly to the skin or mucous membranes without causing significant damage to living tissue.

Disinfectants, on the other hand, are chemicals designed to destroy or inactivate microorganisms on non-living surfaces and objects. They are commonly used to sanitize objects and surfaces in various settings such as hospitals, homes, and schools. Examples of disinfectants include bleach (sodium hypochlorite), quaternary ammonium compounds, and phenolic compounds. These solutions are generally too harsh to be used on living tissue and may cause irritation or damage if applied directly to the skin.

Some chemicals, such as hydrogen peroxide and alcohol solutions, can function as both antiseptics and disinfectants depending on their concentration and method of application. For example, a lower concentration of hydrogen peroxide may be used as an antiseptic on a wound, while a higher concentration can be utilized as a disinfectant on non-living surfaces.

The relationship between temperature, rainfall, and the type of forest is a crucial ecological factor that affects the distribution of various forests globally.

Temperature and rainfall affect forest type in various ways, depending on the geographical location, atmospheric conditions, and other natural variables.

The relationship between temperature and forest type is that warmer temperatures tend to favor tropical and subtropical forests, whereas colder temperatures are ideal for coniferous or boreal forests. Different temperature ranges in various seasons affect the growth rates, evaporation, and transpiration rates of the vegetation within a forest ecosystem.

As a result, the temperature range affects the productivity of a forest ecosystem and the biotic interactions that occur within it.Rainfall, on the other hand, also affects the type of forest that grows in a particular region. Regions that receive high amounts of rainfall support dense forests and vegetation.

Such regions are mostly located in the tropics and are characterized by tropical rainforests. On the other hand, areas that experience low rainfall amounts and dry climates are characterized by grasslands and deserts.

Moderate rainfall amounts can support temperate deciduous forests, whereas boreal forests have a comparatively lower average rainfall amount.

Besides, the type of forest growing in a particular region influences the regional climate through various processes such as transpiration, evapotranspiration, and the release of moisture into the atmosphere.

These processes affect the humidity, temperature, and precipitation patterns in the region. As a result, the relationship between temperature, rainfall, and forest type is a crucial factor that influences ecosystem stability and regional climate patterns.

Reduced permeability of potassium leak channels would affect the time to reach maximum repolarization of the action potential in a neuron.

Potassium leak channels allow potassium ions to passively diffuse out of the cell, contributing to the resting membrane potential of the neuron.

During an action potential, potassium ions move out of the cell through voltage-gated potassium channels, which contributes to repolarization of the membrane potential.

If the permeability of potassium leak channels is reduced, less potassium will be able to leak out of the cell at rest, which would result in a less negative resting membrane potential.

This would increase the excitability of the neuron and may cause it to fire more easily.

During an action potential, the reduced permeability of potassium leak channels would result in less potassium leaving the cell during repolarization, which would slow down the repolarization phase and increase the time to reach maximum repolarization.

This may affect the neuron's ability to fire at high frequencies and could potentially lead to issues with neuronal signaling.

Therefore, option C ("the time to reach maximum repolarization") is the correct answer.

Explanation:

To calculate the number of moles of O2 consumed by a 70-kg man while resting for 1 hour, we can use the ideal gas law, which relates the pressure, volume, temperature, and number of moles of a gas:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.

We can rearrange this equation to solve for n:

n = PV/RT

At 25°C and 100 kPa, the ideal gas constant R is 8.31 J/(mol·K). We can convert the given consumption of oxygen from 14 L/h to volume in m³/s by dividing by 3600:

V = 14/3600 = 0.00389 m³/s

We can also convert the body weight of 70 kg to mass in grams by multiplying by 1000:

m = 70 kg x 1000 = 70,000 g

The molecular weight of oxygen is 32 g/mol, so we can use this to convert the mass of oxygen consumed to moles:

n = (PV/RT) x (molecular weight/mass of air)

At 25°C and 100 kPa, the molecular weight of air is approximately 28.97 g/mol. Plugging in the values, we get:

n = (100000 Pa x 0.00389 m³/s)/(8.31 J/(mol·K) x 298 K) x (32 g/mol/70,000 g)

Simplifying this expression, we get:

n = 0.246 moles of O2

Therefore, the average 70-kg human male consumes approximately 0.246 moles of O2 while resting for 1 hour.

B. A Large growth of algae used up the oxygen in the bay

Answer:

The rock containing clinopyroxene and plagioclase (a type of feldspar) is called either basalt (fine grained extrusive rock) or gabbro (coarse grained intrusive rock). The plagioclase is generally calcium rich i.e. anorthite rich. But rock contains sodium rich feldspar. This means the sodium has replaced calcium. This replacement occurs in underwater (in oceans/seas) extrusion of basalt where sodium from seawater replaces the calcium in anorthite rich plagioclase feldspar. The altered basalt due to sodium exchange is called spilite which contains sodium rich feldspar and pyroxene.

Explanation:

Basalt, a fine-grained extrusive rock, or gabbro, a coarse-grained intrusive rock, are the two terms used to describe the rock that contains clinopyroxene and plagioclase, a form of feldspar. The plagioclase is often anorthite and calcium-rich. But feldspar in rock is abundant in sodium. It follows that calcium has been replaced by sodium.

Rocks are mineral aggregates that combine the characteristics of every trace mineral. Rock types can be distinguished by any particular arrangement of their chemical composition, mineralogy, grain size, texture, or other distinctive features.

For each significant form of rock, many categorization schemes exist as well. In nature, there are several varieties of rocks. Natural rocks seldom ever display such basic traits, and they typically display some variation in the collection of features when the measuring scale shifts.

One of the three basic varieties of rock is igneous rock. When lava or magma cools and solidifies, igneous rock is created. The deposition and subsequent cementation of that material at the earth's surface and in bodies of water results in the formation of sedimentary rocks.

The Earth's crust is mostly made up of metamorphic rocks, which are categorized according to their structure, chemical composition, and mineral assemblage.

Therefore, the plagioclase is often anorthite and calcium-rich. But feldspar in rock is abundant in sodium. It follows that calcium has been replaced by sodium.
