The evidence that matches the review is; Spores don't need to eat and can live under water.

In the scientific parlance, the term evidence entails a proof. It is something that confirms that an assertion is true. The only way that valid evidence could be obtained in science is by conducting an experiment. The experiment must be controlled and the factors that are tested must be adequately randomized to ensure the reliability of the results that we obtain from such a test.

In this case, we need evidence that could prove or disprove the fact that spores are able to survive washing. This prove would be fitted into the evidence section of the cart in the question.

The most valid evidence among the options is that; spores don't need to eat and can live under water.

Answer:

True

Explanation:

Independent variable - Location of the natural park

Dependent variable - The temperature of the area

Constant - Time over which the measurement is taken.

Materials - Thermometer

The term experiment refers to the times in which we try to obtain the effect of the independent variable on the dependent variable. The variable that we manipulate in an experiment is the independent variable while the variable that is altered as we conduct the experiment is the dependent variable.

Now we are trying to perform an experiment that tends to evaluate the effect of the presence of natural parks around urban areas  on the temperature of these areas.

In this case, we have to make a list of at least five natural parks that are located around urban areas and monitor the temperature over each of the areas at regular intervals over a fixed period of time.

In this case;

Independent variable - Location of the natural park

Dependent variable - The temperature of the area

Constant - Time over which the measurement is taken.

El Niño events are indicated by sea surface temperature increases of more than 0.9° Fahrenheit for at least five successive three-month seasons. The intensity of El Niño events varies from weak temperature increases (about 4–5° F) with only moderate local effects on weather and climate to very strong increases (14–18° F) associated with worldwide climatic changes.

The El Niño-Southern Oscillation (ENSO) is a recurring climate pattern involving changes in the temperature of waters in the central and eastern tropical Pacific Ocean.

Whit this information we can conclude that An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.

Diffusion of responsibility is a theory that can be applied to the study of social psychology to explain the bystander effect. This theory states that we are less inclined to assist a stranger in a crowd because we delegate the task to other people there.

The diffusion of responsibility hypothesis claims that we are less inclined to assist a victim in a crowd who we do not know because we believe that assistance will come from people who are familiar with the victim. According to the social psychology concept of Diffusion of Responsibility, being around others makes a person feel less in control or accountable, which makes them believe that someone else, who is more responsible, is already taking care of the situation. Diffusion of responsibility theory is demonstrated in a variety of situations, from failing to intervene when you see someone trip and cry out in agony on the sidewalk to the Holocaust committed by Nazi Germany and its allies against the European Jews during World War II.

Explanation:  body's natural defenses — the immune system — attack the body's own healthy tissue

Diabetes mellitus (DM) is a syndrome of etiology, which is the result of the inability of insulin and/or lack of insulin to properly exercise its purposes. It is characterized by hyperglycemia with disturbances in the metabolism of carbohydrates, lipids and proteins. The difference between type 1 diabetes and type 2 diabetes lies in the fact that, in the first case, there is a reduction or lack of insulin production; in the second, the organism develops resistance to the action of this hormone. Diabetes mellitus is a disease characterized by an increase in blood glucose levels.

Type 1 diabetes mellitus, like type 2, is characterized by excess glucose (sugar) in the blood, which triggers a series of complications in the body. But, in this case, the disease usually appears in childhood and adolescence, brings symptoms such as the urge to urinate and weight loss, and has an autoimmune origin.

Type 2 diabetes is characterized by insufficient production of insulin by the pancreas, or the body's inability to use the insulin produced efficiently. It is more common in people over 40, overweight, sedentary, without healthy eating habits.

The surface area of the cell is 96μm², the volume of the cell is 64 μm³ and the surface area-to-volume ratio is 1.5 μm⁻¹.

The surface area of the cell is the area which is occupied by the surface of the object. The surface area of the cell with six sides of equal measurement = 4 μm.

Surface area of the cell can be calculated by the formula:

Surface area = length × width × number of sides

Surface area = 4 μm × 4 μm × 6

Surface area = 16 μm² × 6

Surface area = 96 μm²

The volume of the cell is the capacity of the cell. It is how much space is present inside the cell.

The volume of the cell with side 4 μm can be calculated by the formula:

Volume = length × width × height

Volume = 4 μm × 4 μm × 4 μm

Volume = 64 μm³

The surface area-to-volume ratio is the surface area divided by the volume of the cell. This indicates how much surface area is available compared to how big or the capacity of the cell is.

The Surface area: Volume ratio can be calculated as:

Ratio = 96 μm²: 64 μm³

So, I don't actually know what cells do this but if you want to think about like traits, scientists believe that it stems from their poor diet of just bamboo and lack of diversity in vegetation. Also, they don't hibernate and they move through different regions throughout the year. Because of this, they have adapted to be camouflaged in those environments at once (and all year round). Studies have shown that other than camouflage, their coloration also helps with communication. It is believed that the black on their ears is a warning to predators and their eye patches are for recognition or possibly aggressive signals.
