How does a diversity of organisms increase the chances that some will survive a major change in environment ?
This can be explained with an example.
Let’s lake an example of two species 1 and 2.
Species 1 has a wide genetic diversity due to which organism are also diverse in phenotype. Their phenotype are:
Black, dark brown, brown, dark red, red, light red, pink, skin color.
From left to right organism are becoming less adapted to high temperature relatively.
For species 2: This species has less genetic diversity and its phenotypic diversity is as follow:
Black, red, Skin color.
From left to right organism are becoming less adapted to high temperature relatively.
Now if there is the sudden high temperature in the environment; 4 Types of phenotype will survive are black, dark brown, brown, dark red.
While there will only two types of organism in specie 2 which will survive are black, red.
So that’s how the diversity of organisms increase the chances that some will survive a major change in environment.

Is space a limiting factor for plant population? Name tow ways
Yes, space is a limiting factor for the plant population.
The space occupied by the plant on the earth determines the amount of the nutrition derived from the soil, if the land is occupied by many plants, the space for the adherence and the nutrient intake would be a factor for competition.
All the plants need sunlight to survive, as it is the source of energy for them. In case, a tree or a plant occupies a huge aerial space, then it would shade the sunlight for the smaller plants, hence, the plants cannot grow in completely shaded region.

(5 points) Let’s take it one step further! Use the data chart below to answer the following question.
Light intensity (%) O2 produced (mL/h)
30 8.8
40 26.1
50 31.3
60 31.3
The data above was collected during an Elodea observation. Notice what happens to the oxygen produced at light intensities of 50% or higher. Everything has its limits, even chemical reactions! Think about a powerful race car. If you give it more fuel and better tires, it can go very fast. But, eventually, its speed will top out due to the limitations of the motor. Even if you kept adding fuel and tires, it couldn’t go any faster. Explain how the data in this experiment suggests there is a maximum photosynthetic rate. Be sure to discuss the reactants and products in your answer.
Answer:
Photosynthesis is the process by which green plants synthesize their food (sugar) from carbon dioxide and water in the presence of sunlight and chlorophyll. Oxygen is released as the byproduct of this process.
In the given experiment, the amount of oxygen produced is taken as the measure of photosynthetic rate.
The rate of photosynthesis is directly proportional to the intensity of light. However, after reaching the maximum rate increase in light intensity also fails to increase it further.
It might be because of the limitations of other factors.
In addition, further increase in light intensity can damage the photo-systems which will results in sharp decrease in photosynthetic rate.
Observations also show that even after increasing the light intensity from 50% to 60%, the oxygen production remains the same i.e. 31.3 ml/h.
The data from the experiment shows that as light intensity increases, oxygen production also increases up to a point, suggesting a maximum photosynthetic rate. Above 50% light intensity, oxygen production plateaus indicating a limiting factor in the photosynthesis process which could be related to carbon dioxide availability or the plant's photosynthetic efficiency.
Explanation:The data from the Elodea observation experiment, where light intensity and oxygen production were measured, suggests a maximum photosynthetic rate. This concept is similar to the analogy of a race car reaching its maximum speed regardless of added fuel or better tires.
For the biological process of photosynthesis, light intensity acts as 'fuel.' When light hits the chlorophyll in a plant, it energizes an electron which initiates the photosynthesis process where solar energy is converted into chemical energy that cells can use. The reactants, or 'inputs' for this process, include light and carbon dioxide. The products, or 'outputs,' include oxygen and glucose.
Looking at the data chart, the oxygen produced — a product of photosynthesis — increases as the light intensity increases up until 50%. However, above 50% light intensity, the oxygen production plateaus at 31.3 mL/h, suggesting the photosynthetic rate has reached a maximum. Similar to the race car analogy, additional light 'fuel' does not increase the oxygen 'speed,' indicating that there is a limiting factor in the photosynthesis process, potentially the amount of carbon dioxide available or the efficiency of the plant's photosynthetic system.

Explanation:
PLATO
Final answer:
In Mendelian genetics, according to the law of segregation, a heterozygous organism has a 50% chance of producing gametes with the recessive allele.
Explanation:
The question relates to Mendelian genetics and the inheritance patterns of alleles. According to the law of segregation, a heterozygous organism (one that has two different alleles for a trait) has a chance of producing gametes with the recessive allele. During gamete formation, alleles for a trait segregate so that each gamete carries only one allele for each gene. This results in a 50% chance of transmitting either allele to the offspring. If an organism is heterozygous for a given trait (Aa), then it has two different alleles: one dominant (A) and one recessive (a). Thus, there is a 50% chance that a gamete produced by a heterozygous organism will contain the recessive allele (a).
Therefore, the correct answers to fill in the blanks would be:

Final answer:
Jill taking a pain reliever for her headache exemplifies conditioned behavior and the use of over-the-counter medication, highlighting a learned response to discomfort that's reinforced by the relief it provides.
Explanation:
Jill has a headache and takes pain reliever to end the pain. This is an example of a(n): conditioned behavior and use of over-the-counter (OTC) medication. When individuals take pain relievers, such as acetaminophen or non-steroidal anti-inflammatory drugs (NSAIDs) to alleviate pain, they are exhibiting a learned response to dealing with discomfort. This behavior is reinforced over time as pain relief follows the act of taking the medication, making it likely that they will turn to pain relievers again in the future. OTC medicines like aspirin, naproxen, and ibuprofen are commonly used for minor aches and pains associated with conditions like headaches, demonstrating a direct action on the pain pathway to alleviate symptoms. This practice is not only about the chemical effect of the medication but also involves psychological elements, such as the expectation of pain relief, which can enhance the overall effect.

Thank you
The enzymes refer to the catalysts that enhance the rate of a chemical reaction without themselves going through any kind of permanent chemical modification. They neither appear as the reaction products nor are used up in the reaction.
During the initial phase of a chemical reaction incorporating enzymes, the substrates combine themselves to the enzyme's active site. Once the suitable substrates combine with an enzyme to produce an enzyme-substrate complex, a chemical reaction between the substrates can take place.
Here's how I think they correspond:
Term: | Match in the graphic:
The process of the enzymatic reaction. | The entire sequence of steps shown in the diagram, from the binding of the reactants (glucose-6-phosphate and ATP) to the release of the products (glucose-6-phospate and ADP).
The substrates for the enzymatic reaction. | Glucose-6-phosphate and ATP.
The name of the enzyme. | Hexokinase.
Binding of the reactants & the occurrence of induced fit. | The interaction between glucose-6-phosphate and ATP with the active site of hexokinase, shown by the dotted lines and the change in the enzyme's shape.
Location on the enzyme where the reaction occurs. | The active site of hexokinase, represented by the pocket where the reactants bind.
Therefore:
Match terms 1, 2, 3, and 5 to the corresponding elements in the graphic as described above.Term 4 ("Occurrence of induced fit") is implied but not explicitly labeled in the graphic.
