Ribosomes are responsible for protein synthesis in the cell.

The Achilles tendon connects the calf muscles to the heel bone, allowing for foot movement.

The cell wall provides protection and support to the cell, maintaining its shape and preventing excessive water uptake.

The primary function of the contraceptive pill is to prevent ovulation, thereby reducing the chances of pregnancy.

Petals are primarily designed to attract pollinators with their color and fragrance.

The Golgi apparatus modifies, sorts, and packages proteins for secretion or delivery to other organelles.

Cortisol is a steroid hormone that helps control the body's stress response and regulates metabolism, immune response, and blood sugar levels.

The primary function of the immune system is to protect the body against diseases and infections.

The lymphatic system is responsible for transporting lymph, a fluid that contains infection-fighting white blood cells, and plays a crucial role in the immune system.

The primary function of the male reproductive system is the production of sperm, which is essential for fertilization.

The myelin sheath acts as an insulator and increases the speed of nerve impulse transmission through saltatory conduction.

Phloem is responsible for the transport of food (sugars) produced during photosynthesis from leaves to other parts of the plant.

The placenta provides oxygen and nutrients to the developing fetus and removes waste products.

The renal pelvis collects urine from the collecting ducts and transports it to the ureter.

Ribosomes are responsible for protein synthesis by translating messenger RNA into polypeptide chains.

The primary function of the root system is to anchor the plant and absorb water and nutrients from the soil.

The rough endoplasmic reticulum is studded with ribosomes and is primarily involved in the synthesis of proteins.

The primary function of the skeletal system in locomotion is to provide a framework for muscle attachment, enabling movement.

The skeletal system serves multiple functions including movement, protection of vital organs, and mineral storage.

The primary function of the small intestine is the absorption of nutrients from digested food.

Surfactant reduces surface tension in the alveoli, preventing their collapse and aiding in gas exchange.

Thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), are crucial for regulating metabolism in the body.

White blood cells are part of the immune system and are primarily responsible for fighting infections and foreign invaders.

The primary goal of gene therapy is to replace defective genes in order to treat or prevent diseases.

The primary goal of sustainable development is to meet the needs of the present without compromising the ability of future generations to meet their own needs.

Charles Darwin proposed the mechanism of evolution known as Natural Selection, which explains how species adapt and evolve over time based on environmental pressures.

Bacteria primarily reproduce asexually through binary fission, where a single cell divides into two identical cells.

The primary mode of nutrition in the kingdom Animalia is heterotrophic.

Angiosperms primarily reproduce through sexual reproduction, involving flowers and seeds.

Ferns primarily reproduce through sexual reproduction, producing spores.
