Answer:

Explanation:B. As the amount of grassland decreases, biodiversity declines.

This statement is supported by the evidence in the graphs. As the human population grows, more land is converted from grassland to cropland, urban areas, and other uses. As the graph on the right shows, biodiversity declines as the amount of grassland decreases. This is likely because grasslands are home to a wide variety of plant and animal species, many of which cannot survive in other types of environments. The loss of grassland habitat can have a significant impact on biodiversity, particularly for species that are specialized to this type of ecosystem.

The statement that is supported by the evidence in the graphs is that as the amount of grassland decreases, biodiversity declines. That is option B, as biodiversity is currently under threat from a range of human activities, such as habitat destruction, climate change, pollution, overfishing, and hunting.

Biodiversity refers to the variety of living organisms, including plants, animals, fungi, and microorganisms, found in an ecosystem or on Earth. It encompasses the genetic, species, and ecosystem diversity of the planet and is a measure of the richness and complexity of life on Earth. Biodiversity is important for maintaining the ecological balance of the planet and for supporting the many ecosystem services that benefit human societies, such as air and water purification, soil formation, nutrient cycling, and climate regulation.

Hence, the statement that is supported by the evidence in the graphs is that as the amount of grassland decreases, biodiversity declines. That is option B.

The distributions of the random variables in the given scenarios are (a) binomial for the water lizards and (b) Poisson for the health center visits. The probabilities can be calculated using the respective formulas for the corresponding distributions.

(a) The distribution of the random variable X, which counts the number of water lizards out of the 25 selected with webbed feet, follows a binomial distribution.

This is because each lizard can be considered as a Bernoulli trial (success: possessing webbed feet, failure: not possessing webbed feet) with a probability of success (p) equal to 61% or 0.61, and the trials are independent.

(b) To compute the probability that exactly 17 of the 25 selected water lizards have webbed feet, we can use the binomial probability formula.

The probability mass function (PMF) for the binomial distribution is given by P(X = k) = C(n, k) * p^k * (1-p)^(n-k), where C(n, k) represents the number of combinations of n items taken k at a time. Plugging in the values, we have P(X = 17) = C(25, 17) * 0.61^17 * (1-0.61)^(25-17).

(c) To compute the probability that at least 17 of the 25 selected water lizards have webbed feet, we need to calculate the cumulative probability from 17 to 25. This can be done by summing up the probabilities for each value of X from 17 to 25: P(X ≥ 17) = P(X = 17) + P(X = 18) + ... + P(X = 25).

(d) The mean (μ) and standard deviation (σ) for the number of water lizards out of 25 who have webbed feet can be calculated using the formulas for the binomial distribution.

The mean is given by μ = n * p, where n is the number of trials (25) and p is the probability of success (0.61). The standard deviation is given by σ = sqrt(n * p * (1-p)).

Moving on to the second scenario:

(a) The distribution of the random variable X, which counts the number of patients that visit the health center during a randomly selected week, follows a Poisson distribution.

This is because the number of patients per week can be modeled as a Poisson process, where events (patient visits) occur independently and at a constant average rate (300 patients per week).

(b) To compute the probability that exactly 310 patients visit the health center during a randomly selected week, we can use the Poisson probability formula.

The probability mass function (PMF) for the Poisson distribution is given by P(X = k) = (e^(-λ) * λ^k) / k!, where λ is the average rate of the Poisson process (300 patients per week) and k is the number of events we are interested in (310 patients).

(c) To compute the probability that more than 280 patients visit the health center during a randomly selected week, we need to calculate the cumulative probability from 280 to infinity. This can be done by summing up the probabilities for each value of X from 280 to infinity: P(X > 280) = P(X = 281) + P(X = 282) + ... + P(X = ∞).

Cellular respiration is the process through which cells convert sugars into energy. The energy comes from the fuel molecules such as Glucose(sugar) or Lipids(fats). In cellular respiration, Glucose molecule is dismantled in the presence of oxygen. The bonds between the glucose break forming a simpler molecule and energy is released in small amounts. Some of the energy is stored by cell in the form of ATP while rest is lost as heat. So, ATP is formed from glucose through endergonic and exergonic reactions. The aerobic breakdown of glucose molecule accompanying synthesis of ATP is called celluar respiration. Carbon dioxide and water are produced as Waste Products.

The airborne mode of virus transmission is considered the most dangerous to humans.

This is because viruses that are transmitted through the air can easily spread and infect a large number of people, especially in crowded places with poor ventilation.

That viruses can survive in the air for long periods of time, allowing them to infect individuals who are not in close proximity to the infected person.

Additionally, viruses that are transmitted through the air can bypass the body's natural defense mechanisms, such as the skin and digestive system, and directly enter the respiratory system.

Hence, airborne transmission poses the highest risk for the spread of viruses among humans.

The term that describes this cumulative amount of land and water required is known as an ecological footprint.

The Global Footprint Network promotes the ecological footprint as a way to assess how much natural capital, or how much nature is required to support people and their economies, is demanded by society.Through an ecological accounting system, it monitors this demand. The accounts compare the biologically productive areas that people utilise for their consumption to the biologically productive areas that are present in a certain region, country, or even the entire globe (known as biocapacity, the productive area that can replenish the natural resources that people use). It is, in essence, a gauge for the extent of human effect on the environment and the sustainability of that impact.

In considering the characteristics given, organism 4 - no body segmentation, no head - would be the most basal or outgroup.

This is because it lacks the defining characteristics of the other organisms, namely body segmentation and/or a head. In evolutionary terms, the presence of body segmentation and a distinct head are considered more advanced or derived characteristics that have evolved from simpler body plans. Organism 5 - no body segmentation, with a head - could be considered more derived than organism 4, but it still lacks body segmentation, which is a more fundamental characteristic. Organisms 1, 2, and 3 all have body segmentation and a head, but differ in the number of body segments and the presence of wings. They could be considered part of a clade that has evolved from the more basal organism 4.

Diatoms are single-celled algae that form distinctive and beautiful cell walls from silica. They are widely distributed throughout the upper layers of the world's oceans, and can also be found in freshwater or humid environments such as the underside of plants. When nutrients are plentiful, large diatoms predominate at the trophic level of the producer, and copepods replace their diet of ciliated protists with diatoms. When nutrient levels are low, the proliferation of small algae outnumbers that of large diatoms, so copepods switch their diet and switch to feeding on ciliates.

The main morphological characteristic of diatoms is the cell wall impregnated with silica (SIO2. nH2O), surrounded by a thin layer of organic matter, known as FRUSTULA.

Enzymes catalyze chemical reactions by lowering the activation energy, allowing the reaction to take place more quickly or even to take place at all.

Enzymes are proteins that act as catalysts, meaning they speed up chemical reactions. Enzymes are found in all living things and are essential for life. They are specific to the reactions they catalyze, meaning they can only catalyze a specific reaction. Enzymes work by binding to the substrates of the reaction and bringing them together in the right orientation. This lowers the activation energy necessary to start the reaction and allows it to occur more quickly. Enzymes have an active site which is where the substrates bind and the reaction occurs.

Explanation:

Chloride cells in the gills of saltwater fish actively transport chloride ions from the fish's body to the external environment, helping the fish regulate its internal chloride ion concentration and maintain ion balance in a hyperosmotic environment. The correct option is c.

In saltwater fish, chloride cells in the gills are responsible for maintaining the appropriate balance of ions, particularly chloride ions (Cl-) in the fish's body. These cells actively transport chloride ions, but the direction of transport depends on the specific concentration gradients.

When saltwater fish are in an environment with a higher chloride ion concentration outside their bodies, the chloride cells in the gills actively transport chloride ions from the external environment (saltwater) to the extracellular fluid (ECF) within the fish's body.

This helps the fish maintain a higher chloride ion concentration inside its body, necessary for osmoregulation and ion balance.

Therefore, the correct option is b) actively transport Cl- from the external environment to the ECF. The chloride cells in the gills utilize energy to pump chloride ions against their concentration gradient, ensuring that the fish retains enough chloride ions despite their constant loss through osmosis.

This active transport mechanism is essential for the survival of saltwater fish, as it enables them to regulate their internal ion concentration and counteract the osmotic stress caused by living in a hyperosmotic environment.

Hence, the correct option is c) actively transport cl- from the ecf to the external environment.
