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

• A wedge is an object with at least one slanting side ending in a sharp edge, which is used to cut or split material apart.
• Examples: Axes, knives, chisels, plough nall, sharpener, iron nails and pins (push pin).

Explanation

When the parachute opens, the air resistance increases.

The skydiver slows down until a new, lower terminal velocity is reached.

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

All the isotopes of the same element have the same number of protons, which defines the element.

Different isotopes can exist depending on the neutron count.

Electrons are negatively charged and can counterbalance the positive charge of protons.

Also, they are present in equal numbers in neutral atoms of the same element.

Explanation

When two resistances are connected in parallel, the net resistance (Rnet) is calculated using the formula:

1/Rnet = 1/R1 + 1/R2

where R1 and R2 are the individual resistances.

In this case, R1 = 6 Ω and R2 = 12 Ω, so:

1/Rnet = 1/6 + 1/12 = 1/4

Rnet = 4 Ω

Therefore, the net resistance of the two resistances connected in parallel is 4 Ω.
