The G2 phase is primarily for preparing the cell for mitosis, including the synthesis of proteins necessary for cell division.

The genetic code determines the sequence of amino acids in proteins, thus influencing their structure and function.

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

Aldosterone helps regulate blood pressure by controlling sodium and water balance in the kidneys.

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

Oxytocin is primarily responsible for stimulating uterine contractions during childbirth.

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

The integumentary system, which includes the skin, hair, and nails, serves to protect the body, regulate temperature, and provide sensory information.

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.

Mitochondria are known as the powerhouse of the cell, where cellular respiration occurs to produce ATP.

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

The pancreas produces digestive enzymes that help in the digestion of carbohydrates, proteins, and fats.

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.

The primary function of the respiratory system is to exchange gases, specifically to take in oxygen and expel carbon dioxide.

Ribosomes are the cellular structures responsible for synthesizing proteins by translating messenger RNA (mRNA).

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.

The style connects the stigma to the ovary, allowing pollen to travel to the ovules.

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.
