The two objects on the slide that the students noticed are cheek cells and bacteria.

Cheek cells are the cells that line the inside of your cheek. They  shed constantly and are also replaced by new cells.

Bacteria are microscopic organisms that live on and in our bodies. There are many different types of bacteria, and they can be found in all parts of our bodies, including our mouths.

Bacteria are not all bad. Some of them are important for our health because they help to break down food and they produce vitamins that we need.

The student was able to see the cheek cells and bacteria on the slide because they were stained with a dye called methylene blue.

Answer:

\(\boxed {\boxed {\sf D. \ During \ the \ time \ labeled \ D, \ when \ the \ temperature \ stays \ the \ same}}\)

Explanation:

Phase changes have to happen at a specific temperature. During a phase change, the energy is used to make the change happen, instead of raising the temperature.

On a graph, a constant slope, or in this case temperature, is a flat line. On this graph, the flat lines are at B and D.

There is no answer including B, but there is for D.

Choice D: During the time labeled D, when the temperature stays the same is correct.

A scientific argument is a method that researchers use to direct their work. In order to ultimately improve rational explanations and experimental designs, scientists point out flaws and limitations in other people's arguments. Evidence-based arguments is the term for this technique.

The aim of scientific reasoning is to assess the reliability and validity of methods and results. It would be appropriate to accept the scientific research if one could validate and demonstrate all of the points made. This part is structured around the four components of scientific argumentation

The method by which research, as a field, creates and greater integration, is through scientific debate. Other scientists assess and analyze the assertions, supporting evidence, and explanations of that evidence when scientists make arguments in favor of novel theories.

Depending on the temperature and length of exposure, heat can affect eggs in a number of different ways.

These are a few potential outcomes:

Cooking: Egg proteins are denatured and coagulated by heat during cooking, solidifying the egg white and yolk. When an egg is boiled, fried, or baked, this occurs.

Toughening: Eggs can become rigid, rubbery, or dry if they are overcooked or exposed to intense heat over an extended period.

Nutritional loss: Heat can make some nutrients in eggs, like vitamin B12 and folate, less absorbable or destroy them.

Spoilage: Bacteria can quickly proliferate if eggs are exposed to heat for an extended period of time at room temperature or in a warm environment, which can result in spoilage and possible foodborne illness.

Color Change: Heat can cause an egg yolk's color to change from yellow to greenish-gray or even dark green as a result of the interaction between sulfur compounds in the egg white and iron in the yolk. This is typically observed in hard-boiled or overdone eggs.

Overall, while heat is necessary for cooking eggs, it's essential to use the proper temperature and cooking time to achieve the desired texture and prevent nutrient loss or spoilage.

Lentic ecosystems tend to have smaller volumes of water compared to Lotic ecosystems.

Lentic ecosystem consists of still (stagnant) volume of water and good examples include ponds,lakes, basins etc.

Lotic ecosystem , on the other hand consists of a flowing volume of water and examples include seas, oceans, rivers etc.

The Lentic ecosystem usually is usually still and is affected by seasonal changes as it contains smaller volume of water when compared to the Lotic ecosystem which has a high volume.

Seasonal changes such as summer or winter affects the Lentic system easily as the small volume of water gets heated up and frozen easily which encourages more evaporation and freezing respectively.

Answer:

The products of a glycolytic metabolism is lactic acid and the increase of the insulin enzyme at the plasma level.

Explanation:

Lactic acid is the product of the reaction of glucose catalysis in oxygen-deficient states such as in anaerobic activity.

Lactic acid is an acid that can be metabolized by the body, which accumulates in the muscles, and is generated once the physical activity has finished or in the last stages.

Insulin, once generating the rest of the activity, or the cessation of the action, comes into play at the plasma level and increases, in order to neoform new energy reserves (glucose) and thus prepare for the next action.

This hormone has the opposite effect to glucagon.

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.

Explanation:

Scientific knowledge is open to change because it is based on the systematic and ongoing process of observation, experimentation, and analysis. As new evidence becomes available, scientists reassess their theories and hypotheses to align with the most accurate and current understanding of the subject.

In the case of Giovanni Schiaparelli's observations of Mars, his initial interpretation of the lines on the planet's surface as "channels" was later translated into English as "canals." Percival Lowell further popularized this idea by drawing maps depicting a fictional Martian civilization with a network of canals.

However, as technology improved and more detailed observations of Mars were made with better telescopes, it became clear that there were no actual canals on the planet. The new evidence did not support the earlier interpretations of observations, indicating that the existence of Martian canals was a misinterpretation or a product of human imagination.

This example demonstrates how scientific knowledge can evolve and change based on new evidence that challenges or contradicts previous ideas. It highlights the importance of critical evaluation, rigorous experimentation, and openness to revising theories in the face of new information.
