Explanation

Human plasma proteins consist of:

• Fibrinogen (A): involved in blood clotting
• Albumin (C): helps regulate blood volume and transport various molecules

Explanation

• Glucose is the fundamental molecule produced during photosynthesis.
• It is then used by the plant cell as energy and building block for the synthesis of other organic compounds.
• Like cellulose, starch, and other carbohydrates.

Explanation

In cellular respiration, each mole of glucose typically produces about 36-38 ATP molecules.

To determine how many moles of glucose are consumed to produce 180 ATP molecules, we can use the following calculation:

180 ATP/36 ATP or mole of glucose = 5 moles of glucose

Thus, 5 moles of glucose are consumed to produce 180 ATP molecules.

Explanation

• In Telophase, the chromatids (now called chromosomes) have reached the poles of the cell and their movement ceases.
• The nuclear envelope begins to reform around each set of chromosomes, and the cytoskeleton reorganizes to prepare the cell for cytokinesis (cell division).

Explanation

• During prophase of mitosis in an animal cell, separation of centrioles occurs.
• The centrioles move to opposite poles of the cell to help organize the mitotic spindle.

Explanation

In the human body, there are more than 1,000 known enzymes.

These enzymes play essential roles in catalyzing biochemical reactions.

Explanation

Observation is the first step in the scientific method, which is used to solve biological problems.

Scientists make observations about the natural world, notice patterns or phenomena, and ask questions about what they have observed.

The correct order of the scientific method is:

• Observation
• Question
• Hypothesis
• Prediction
• Experimentation
• Data analysis
• Conclusion

Explanation

• Optimum pH is the point where an enzyme is most active.
• It is the pH at which the enzyme catalyzes the reaction at its maximum rate. 
• Different enzymes have different optimum pH values, depending on their structure and function.

Explanation

• In metaphase, the chromosomes (now consisting of two sister chromatids each) align themselves at the center of the cell, attached to the microtubules of the mitotic spindle.
• This forms the metaphase plate, where each chromosome is positioned at the equator of the cell, ready for separation.

Explanation

Biodiversity is impacted by various human activities, including:

• Pollution: Chemical pollutants can alter ecosystems, affecting species development, growth, and survival.
• Deforestation: Habitat destruction and fragmentation lead to population decline, isolation, and extinction.
• Overhunting: Overexploitation of species for food, trophies, or other purposes can deplete populations and drive extinctions.
