at birth around 5 million red blood cells per mm3 of blood is present

4.5 to 5.5 millions per cubic mm.
What are red blood cells (RBCs)?
RBC s is an abbreviation for Red blood cells found in the blood cells of living organisms.
RBC s are important in the transport of oxygen in the body.
RBC s contain a special red coloured pigment called haemoglobin which binds with oxygen and transports it to different body parts.
RBC s are synthesized in the bone marrow. Erythropoietin hormone helps in the synthesis of RBC s.
RBC s are biconcave and disc shaped in mammals . They lack nucleus .
RBC s are estimated and expressed in cubic per mm of blood . RBC s in men is little higher than the females .
Inadequate number of RBC s in the blood can lead to various haemoglobinopathies . Anaemia is the common condition among many.
Fatigue , dizziness , lethargy are the common symptoms of anaemia .
Low number of RBC s impact oxygen transport in the body .
Therefore, RBC s are crucial for living organisms.

At birth, the average number of red blood cells per cubic millimeter of blood is approximately 4.5 to 5.5 million. Red blood cells are essential for transporting oxygen in the body and are produced in the bone marrow. Their count can vary based on health and environmental factors.

Untuk soal ini, kita gunakan rumus peluruhan eksponensial karena intensitas cahaya berkurang secara persentase tetap tiap meter.⸻ Diketahui: • Intensitas awal (P₀) = 100% (misalnya) • Penurunan = 3,5% per meter → tersisa 96,5% per meter • Kedalaman (K) = 5 meter • Rumus peluruhan:P = P₀ \times (1 - r)^KatauP = P₀ \times (0.965)^K⸻✅ Hitung:P = 100\% \times (0.965)^5P = 100\% \times 0.837P \approx 83.7\%⸻✍️ Jawaban akhir:Intensitas cahaya pada kedalaman 5 meter adalah sekitar 83,7% dari intensitas di permukaan.Kalau intensitas awal diketahui dalam satuan (misalnya watt/m²), tinggal kalikan saja nilainya dengan 0,837.
