Symbiotic mutualism is a type of relationship in which two different species of organisms live together in a mutually beneficial association. In this type of interaction, both species benefit from the presence of the other, and their survival and reproductive success are enhanced.

In a symbiotic mutualistic relationship, the two species can interact in different ways. For example, some species can live in close physical association with each other, while others may interact through chemical signals or other means of communication. In many cases, the relationship is so close that the two species become dependent on each other for survival. A classic example of symbiotic mutualism is the relationship between bees and flowers. Bees collect nectar from flowers, which they use as food, while at the same time transferring pollen from the male parts of the flower to the female parts, enabling the plant to reproduce. In this way, both the bees and the flowers benefit from the relationship.

Other examples of symbiotic mutualism include the relationship between ants and certain species of plants, in which the ants protect the plants from predators and in return receive food and shelter; and the relationship between certain species of bacteria and animals, in which the bacteria live in the digestive tract of the animal and help to break down food, while at the same time receiving a steady supply of nutrients.

Overall, symbiotic mutualism is an important type of relationship in which both species involved benefit from the association, and it plays an important role in many ecosystems.

The energy of one photon of red light with a wavenumber of 15240 cm⁻¹ is 2.06 x 10⁻¹⁸ joules. The energy for one mole of photons of red light is 1.24 x 10⁵ joules.

When considering the energy of one photon of red line, it can be calculated using the equation E = hc/λ, where E represents energy, h is Planck's constant, c is the speed of light, and λ is the wavelength of light. By converting the wavenumber to wavelength and substituting the values into the equation, we find that the energy of one photon is 2.06 x 10⁻¹⁸ joules.

To calculate the energy for one mole of photons, we multiply the energy of one photon by Avogadro's number, which represents the number of particles in one mole. This gives us the total energy for one mole of photons of red light, which is 1.24 x 10⁵ joules.

In summary, the energy of one photon of red light is 2.06 x 10⁻¹⁸ joules, and the energy for one mole of photons of red light is 1.24 x 10⁵ joules.

Answer:

140 km per hour.

Explanation:

350 divided by 2.5= 140

The average speed of the train was 140 kilometers per hour.

Speed ​​is a unit used to describe how fast something is moving with respect to another object. Due to its scalar nature, it has only magnitude and no direction. By dividing the distance traveled by an object by the time required to cover that distance, one can calculate its speed.

The formula for calculating speed is as follows:

Speed = Distance / Time

In the International System of Units (SI), the meter per second (m/s) is the accepted unit for measuring speed. Nevertheless, other common units for speed include kilometers per hour (km/h) and miles per hour (mph), depending on the situation and location.

We can use the following calculation to determine the typical speed of a train:

Average speed = Distance traveled / Time taken

In this example, the train covered this distance of 350 km in 2.5 hours.

Average speed = 350 km / 2.5 hours

Average speed = 140 km/h

Therefore, the average speed of the train was 140 kilometers per hour.

Only heritable features in the population are affected by natural selection, which favours  b. advantageous alleles by increasing their frequency in the population while favouring detrimental alleles by decreasing their frequency. This process is known as adaptive evolution.

Evolution is the shift through time in the inherited traits of biological populations. Genes, which are transmitted from parent to offspring during reproduction, express themselves in the form of certain traits. As a result of genetic recombination and mutation, variation frequently exists within a particular population. When these variations are subjected to evolutionary processes like natural selection (which includes sexual selection) and genetic drift, they give rise to evolution, which is when particular traits within a population start to become more or less prevalent. A change in heritable features emerges across successive generations as a result of the shifting evolutionary pressures that determine whether a trait is frequent or rare within a population. Every level of biological organisation, including has experienced the emergence of biodiversity as a result of this process of evolution.

To test the hypotheses regarding the observed frequencies of characteristics A, B, C, and D, we can use a chi-squared goodness-of-fit test. This test will help determine whether the observed frequencies significantly deviate from the expected frequencies based on the hypothesized ratios.

Let's proceed with the hypothesis test:

Step 1: Define the hypotheses:

H0: p1 = 9/16, p2 = 3/16, p3 = 3/16, p4 = 1/16 (the observed frequencies follow the expected 9:3:3:1 ratio)

H1: At least two proportions differ from those specified.

Step 2: Set the significance level (α):

The significance level, denoted as α, determines the threshold for deciding whether to reject the null hypothesis. Let's assume a significance level of α = 0.05, which is a common choice.

Step 3: Calculate the expected frequencies:

Based on the hypothesized ratios, we can calculate the expected frequencies for each characteristic. Since the sample size is 160, we multiply each proportion by 160 to obtain the expected frequencies:

Expected frequency for A: (9/16) * 160 = 90

Expected frequency for B: (3/16) * 160 = 30

Expected frequency for C: (3/16) * 160 = 30

Expected frequency for D: (1/16) * 160 = 10

Step 4: Perform the chi-squared test:

We can now calculate the chi-squared statistic using the formula:

χ² = Σ((O - E)² / E)

where Σ represents the sum over all categories, O is the observed frequency, and E is the expected frequency.

For our example:

Observed frequencies: O(A) = 82, O(B) = 35, O(C) = 29, O(D) = 14

Expected frequencies: E(A) = 90, E(B) = 30, E(C) = 30, E(D) = 10

Calculating the chi-squared statistic:

χ² = ((82-90)² / 90) + ((35-30)² / 30) + ((29-30)² / 30) + ((14-10)² / 10)

Step 5: Determine the critical value:

The critical value is obtained from the chi-squared distribution table or using statistical software. The degrees of freedom for this test are equal to the number of categories minus 1. In our case, there are 4 categories, so the degrees of freedom (df) = 4 - 1 = 3.

With α = 0.05 and df = 3, the critical value is approximately 7.815.

Step 6: Make a decision:

Compare the calculated chi-squared statistic to the critical value. If the calculated value is greater than the critical value, we reject the null hypothesis (H0). Otherwise, we fail to reject H0.

If the calculated chi-squared statistic is less than or equal to the critical value, we fail to reject the null hypothesis (H0), which means the observed frequencies do not significantly deviate from the expected frequencies based on the hypothesized ratios.

Answer:

A: That all living things are made of cells

Explanation:

Answer:

Plants perform both photosynthesis and cell respiration and cause a net decrease of carbon in the atmosphere.

Explanation:

Plants are living organisms capable of performing a process called photosynthesis, which they use to synthesize their food (sugar). They use carbon in form of carbon dioxide, which they absorb from the atmosphere via their stomata.

However, plants like every other living organism, also perform cellular respiration. Cellular respiration releases carbon in form of carbon dioxide into the atmosphere. Plants use more carbon dioxide than they release into the atmosphere, hence, they contribute to global carbon cycle perform both photosynthesis and cell respiration and cause a net decrease of carbon in the atmosphere.
