Explanation

One mole of glucose (180g) produces a maximum of 2827 kJ (kilojoules) of energy through cellular respiration.

This energy is released as ATP (adenosine triphosphate) and is used to power various cellular activities.

Explanation

Genetic engineering is also known as genetic modification or biotechnology.

It is the process of altering an organism's genes to produce a desired trait or characteristic.

This can involve the transfer of genes from one organism to another, or the alteration of existing genes within an organism.

Explanation

Plants, algae, and some bacteria use photosynthesis to convert simple inorganic molecules like carbon dioxide (CO2) and water (H2O) into glucose (a type of sugar) and oxygen (O2).

This process is essential for life on Earth, as it provides energy and organic compounds for food chains.

Explanation

Chromatids are the two genetically identical copies of a chromosome that are joined at the centromere.

They are made up of chromatin and contain the same genetic information.

During cell division, the chromatids separate, and each becomes a separate chromosome.

Explanation

Diffusion is a passive process, meaning it does not require energy input.

In diffusion, particles move from an area of higher concentration to an area of lower concentration until they are evenly distributed, without the use of energy.

Explanation

The final step of the scientific method is developing a conclusion.

It involves summarizing the findings, interpreting the data, and determining whether the hypothesis was supported or rejected.

The scientific method steps in order:

• Observation
• Hypothesis
• Prediction
• Research
• Experimentation
• Data Analysis
• Conclusion

Explanation

• The sequence of physiological changes by which a cell commits suicide is called apoptosis.
• This is a controlled, programmed cell death process that is crucial for maintaining healthy tissue function and development.

Explanation

Peristalsis is a wave of rhythmic movements of muscle contraction and relaxation that helps move substances through a tubular structure, like the digestive tract.

It's a vital process that facilitates the transport of food, water, and waste products through the digestive system.

Explanation

Enzymes lower the activation energy, allowing the reaction to proceed faster and more efficiently.

This enables the reaction to occur with less energy input, making it more feasible and rapid.

Explanation

Electron microscopes produce higher-resolution images due to the shorter wavelength of electrons compared to visible light.

This enables them to reveal smaller details and structures that are not visible with light microscopes.
