Digestion begins in the mouth. All of the statements are correct. The tongue aids in the digestion of food by moving the food around the mouth and helping to mix it with saliva.

Digestion is the process of breaking down food into smaller molecules that can be absorbed and used by the body.  Saliva contains enzymes that change some of the starches in the food to sugar, which begins the process of breaking down the carbohydrates in the food. The tongue also helps to keep the food in place in the mouth while it is being chewed, which allows for more efficient grinding and mixing of the food with saliva. Finally, chewing breaks down the food into smaller pieces, which makes it easier for the digestive juices to react with the food and begin the process of digestion.

When two closely related birds live on separate islands and do not interbreed, the temporal isolation is occurring.

Temporal isolation is a type of reproductive isolation mechanism among sexual organisms in which the differences in the timing of critical reproductive events prevent members of closely related species.

Temporal isolation happens when two or more species reproduce at different times. For example, three species of orchid live in the same rain forest. Each species has flowers that last only one day and must be pollinated on that day to produce seeds.

One prezygotic reproductive barrier is temporal isolation. Temporal isolation means 'isolated in time,' so this is a mechanism that prevents species from mating because they breed at different times.

Answer:

When the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.

Explanation:

According to the Nernst equation the potential of the membrane for a two-compartment model of a cell for positive gradient of K⁺ ions is V = - 60 mVlogK'/K where K' = inside concentration of K⁺ ions and K = outside concentration of K⁺ ions. For a 10 fold excess of KCl in the inside compartment, K'/K = 10. So,

V = - 60 mVlogK'/K = - 60 mVlog10 = -60 mV.

For a negative gradient of Na ions is V = + 60 mVlogK'/K where K' = inside concentration of Na⁺ ions and K = outside concentration of Na⁺ ions. (Since the cell is selectively permeable to Na⁺ ions. So, Na ions to not flow out but in.)For a 10 fold excess of NaCl in the inside compartment, K'/K = 10. So,

V = + 60 mVlogK'/K = + 60 mVlog10 = +60 mV.

So, when the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.

The interphase is a part of the cell cycle in which DNA replication occurs in the cell in order to enter mitosis, it is like the moment of preparation before cell division. It is commonly called also resting phase.

It will not be part of mitosis but it is before it starts. It will be composed of the G1 phase in which there is protein synthesis so that the cell will increase in volume, the S phase in which DNA synthesis is generated and the G2 phase in which the cell prepares for cell growth. division.

Answer:

The correct answer is - They secrete acid that breaks away rocks

Explanation:

Lichen causes chemical weathering to break the rocks quickly which is the excretion of various acids like oxalic acid and many more organic acids that can cause a significant impact on the rock by dissolving minerals.

By breaking the rocks it forms the ground for the plant that will come later in place of the bare rocks by this chemical weathering process. An example of chemical weather is a change of the granite to clay with the help of hydrolysis.

The statement not supported by Kettlewell's data is "Light moths had a survival disadvantage in industrial Dorset," while the other statements are supported by the experiment's results.

The statement that Kettlewell's statistics does not support is: "Light moths had a survival disadvantage in industrial Dorset."Kettlewell's data showed that dark moths had a survival advantage in forested Birmingham, where the tree trunks were darkened by pollution, making the dark moths harder to spot by predators. In contrast, light moths had a survival advantage in forested Birmingham before industrialization when tree trunks were lighter in color.

In industrial Dorset, where pollution had darkened the tree trunks, Kettlewell found that dark moths had a survival advantage, as they were better camouflaged against the darker tree trunks. Light moths, on the other hand, had a survival disadvantage in industrial Dorset, as they were more visible to predators against the darkened tree trunks.

Therefore, all the statements except "Light moths had a survival disadvantage in industrial Dorset" are supported by Kettlewell's data.

The graph shows the results of a famous biological experiment. In the experiment, Kettlewell believed that the peppered moth demonstrated how environmental pressures influence evolution. He studied two areas. Birmingham was a rural wood, with natural conditions. Dorset was an urban, industrial area. The moths use tree trunks to camouflage themselves against birds, which are their major predators. Natural gene variations produce a light form of the peppered moth, and a dark form, meaning that they are not equally visible.

All BUT ONE statement is supported by Kettlewell's data. That is

Answer:

A necessary condition for the changes in the finch populations to occur in response to the drier climate would be:

- Variation in beak shape within the initial population: There must have been existing genetic variation in the population of finches regarding beak shape. Some finches would have had the beak shape that provided an advantage in obtaining food resources in the drier climate, while others would have had different beak shapes.

Without this initial variation in beak shape, there would be no opportunity for natural selection to act and favor individuals with the advantageous beak shape. Therefore, the presence of genetic variation within the population is necessary for the changes in the finch populations to occur.

Based on the theory of natural selection, the necessary condition for the changes in the finch populations to occur is limited food resources. Option B

Natural selection is the process by which populations of living organisms adapt and change over time.

Natural selection occurs when there is variation within a population of a species, and some individuals are better able to survive and reproduce than others.

These individuals are more likely to pass on their genes to the next generation, and the population will gradually change over time.

The above answer is based on the full question below;

Over time, the climate of an island became drier, which resulted in changes to the populations of various island finch species. Finch populations with a certain beak shape thrived, while those not having that beak shape decreased, Which of the following describes a necessary condition for these changes in the finch populations to occur?

The prompt is culled from "HonerScience" Gizmo. The objective is the compare the Planetary motion of Pluto's Orbital Radius, against the period of it's Orbit as depicted in the Gizmo. It is to be noted that Pluto's Orbital Radius is 39.529 AU while it's period of Orbit is 249 years.

For roughly circular orbits, the orbital radius is the distance between an item in space and the body it is circling. When an object circles a body in space, it spins around it, forming a circle or an ellipse depending on the orbit.

If the mass of the orbiting star is known, Kepler's Third Law may be used to calculate the planet's orbital radius (R3=T2Mstar/Msun, the radius is in AU, and the period is in earth years).

The earth's radius and the radius of its orbit around the sun are 6371 km and 149x109 km, respectively.
