Explanation:

Answer:

one can be a plant and the other an animal

Answer:

The answer is option number 3. "Climax community"

Explanation:

The term that best relates to equilibrium is "climax community." A climax community is the final and stable stage of succession, where the community of organisms is in a state of equilibrium with its environment. This community is characterized by a diverse array of species that have reached a balance in their population sizes and interactions with one another and the environment. In other words, the climax community represents a state of ecological balance or equilibrium. In contrast, primary succession and secondary succession refer to the initial stages of succession in a newly formed or disturbed environment, while pioneer species are the first organisms to colonize such environments.

The statement that best explains the activity levels of trypsin in Figure 1 is (D) At extremely low pH values, trypsin is denatured and cannot function

efficiently.

Figure 1 shows the activity levels of trypsin, a protease enzyme of small intestine, as a function of pH.

The data indicates that trypsin is most active in moderate pH ranges, between 6 and 8, where it exhibits its highest activity levels. However, as the pH values become more acidic or basic, the activity of trypsin decreases significantly.

At extremely low pH values, trypsin is denatured and cannot function efficiently. This is evidenced by the sharp drop in activity at pH levels below 4.

Therefore, the statement that best explains the activity levels of trypsin in Figure 1 is (D).

Apart for acute eyesight for finding prey, all of the above are adaptations of herbivores.

The big, flat, and rough surfaces of a herbivore's molars crush the tough plant tissues (back teeth). Many herbivores, including squirrels, have front teeth with chisel-like edges for breaking through tough objects like wood or seeds. These teeth are constantly growing in order to prevent wear and tear.

Herbivores must rely on mutualistic, internal symbiotic bacteria, fungi, or protozoa to break down complex cellulose in order for the herbivore to consume it. By detoxifying plant secondary metabolites, microbial symbionts also enable herbivores to consume plants that might otherwise be poisonous.

An organic acid is lactic acid. Its chemical formula is CH3CH(OH)COOH. It is miscible with water and has a white solid state.

Thus, It transforms into a colorless solution when dissolved. In the process of production, both synthetic and natural resources are used. Due to the presence of a hydroxyl group next to the carboxyl group, lactic acid is an alpha-hydroxy acid (AHA).

It serves as a synthetic intermediate in a number of biochemical and organic synthesis industries. Lactate (or the lactate anion) is the conjugate base of lactic acid. The resulting acyl group is known as lactoyl.

Lactic acid has two enantiomers and is chiral. One is called l-lactic acid, (S)-lactic acid, or (+)-lactic acid, while the other, which is d-lactic acid, (R)-lactic acid, or ()-lactic acid, is its mirror image.

Thus, An organic acid is lactic acid. Its chemical formula is CH3CH(OH)COOH. It is miscible with water and has a white solid state.

The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).

1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).

Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).

Now we can express the ratio between 92 mL and 88.72 mL:

92 mL : 88.72 mL

Simplifying the ratio by dividing both sides by the greatest common divisor, we get:

46 : 44

So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

Answer:

Scientific Theory

Explanation:

The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.

In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.

Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.

In Activity 2, the respirometer C serves as the control. A control is an essential part of any scientific experiment as it provides a baseline against which the experimental results can be compared.

Respirometer C containing only plastic beads does not contain any living organisms and therefore does not undergo cellular respiration. By comparing the results of respirometers A and B with the control (respirometer C), any changes in oxygen consumption and carbon dioxide production can be attributed to the metabolic activity of the germinated beans in respirometer A and the dormant beans in respirometer B.

This allows researchers to determine the specific effects of germination on cellular respiration by isolating the variables and eliminating any external factors that could influence the results.

The temperature gradient between points A and B is 0.1°C/m and keeping other conditions constant, if the mantle and the crust were closer to each other then the temperature gradient between the two would increase.

The temperature gradient between points A and B is 0.1°C/m. This means that for every meter traveled between the two points, the temperature decreases by 0.1°C. Therefore, the temperature difference between the two points can be attributed to their distance apart.
If the mantle and the crust were closer to each other, the distance between them would decrease. As a result, the temperature gradient between the two would increase. This is because a shorter distance would mean that there is less space for the heat to dissipate, leading to a greater temperature difference over a shorter distance.
The exact increase in temperature gradient would depend on the new distance between the mantle and the crust. However, it can be predicted that the temperature difference between the two points would increase as the distance between them decreases.
In summary, if the mantle and the crust were closer to each other, the temperature gradient between the two would increase. This would lead to a greater temperature difference over a shorter distance.
