Explanation

Lost organ refers to a characteristic that is acquired due to injury or environmental factors.

It is not passed down to offspring, making it non-heritable.

Traits like eye color, height, and detached ear lobes are genetically inherited.

Explanation

Dialysis is a medical treatment used when the kidneys are unable to filter waste products from the blood, typically in renal (kidney) failure.

It helps maintain proper fluid and electrolyte balance in the body.

Explanation

Photosynthesis, the process of food synthesis in plants, primarily occurs in the leaves.

Leaves contain chlorophyll, which captures light energy to produce food from carbon dioxide and water.

Explanation

Creeping animals (such as snakes, lizards, and turtles) are typically classified under the class Reptiles.

Reptiles are cold-blooded and move by creeping or slithering on land.

Explanation

DNA is the fundamental molecule that carries genetic information, forming the basis of heredity alongside chromosomes and genes.

It is the hereditary material in almost all organisms, encoding the instructions for building proteins and other important molecules.

Explanation

Potassium is an essential nutrient for plants, helping with growth, disease resistance, and water regulation.

Along with nitrogen and phosphorus, it is one of the primary macronutrients needed for healthy plant development.

Explanation

The breakdown of proteins results in the production of ammonia, which is then converted into urea in the liver.

Urea is excreted from the body through the kidneys in the urine.

Explanation

The ureter transports urine from the kidneys to the urinary bladder.

The urinary bladder stores urine until it is ready to be expelled from the body.

Explanation

Cell wall is not a part of animal cells; it is found only in plant, fungal, and bacterial cells.

Animal cells have a cell membrane, cytoplasm, and vacuole (though smaller than in plant cells).
