Explanation

 An autotrophic organism is an organism that produces its food, so the correct answer is Algae. 

Algae use photosynthesis to create their own food from sunlight, water, and carbon dioxide, making them a prime example of an autotroph. 

Explanation

 A dilute solution compared to cell concentration is termed hypotonic

This means the solution has a lower concentration of solutes (and a higher concentration of water) than the cell's internal environment. 

Explanation

Choanocytes, also called collar cells, are flagellated cells found in parazoans (sponges).

They help in capturing food particles and aiding digestion by creating a water current.

Explanation

Explanation

We breathe in oxygen, which is essential for the survival of most living organisms.

Oxygen is used by our cells to produce energy through a process called cellular respiration.

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

DNA replication is the process by which a cell makes an exact duplicate of its DNA before cell division.

This process involves the unwinding of the double helix, the synthesis of a new complementary strand.

The formation of two identical daughter molecules.

Explanation

Rickets is a condition that affects children, causing softening and weakening of bones due to a deficiency of vitamin D, calcium, or phosphorus.

This leads to bowed legs, stunted growth, and other skeletal deformities.

Explanation

Transpiration is the process by which plants remove excess liquid water from their tissues and release it into the air as water vapor.

This process occurs mainly through the leaves and stems of plants and is an important part of the water cycle.
