Statements 1, 2 and 4 are correct.

Statement 1: Coffee needs a warm and moist climate with temperatures generally ranging from 15°C to 28°C. A spell of dry weather is required during the ripening period for harvesting. This statement is correct.
Statement 2: Coffee plants thrive on well-drained soil. Rolling fields and hilly slopes provide excellent drainage, preventing waterlogging, which is detrimental to coffee roots. This statement is correct.
Statement 3: While coffee needs sunshine, strong direct sunshine, especially exceeding 35°C, is generally harmful. Coffee is often grown under shade trees in India to regulate temperature and sunlight intensity. This statement is incorrect.
Statement 4: Karnataka is indeed the largest producer of coffee in India, accounting for over 70% of the country’s total production. Kerala and Tamil Nadu are the other major producing states. This statement is correct.

Arabica and Robusta are the two main varieties of coffee grown in India. Indian coffee is highly regarded globally, particularly for its unique flavor profiles due to cultivation under shade. The coffee plantations are primarily concentrated in the Southern states of India in the Western Ghats region.

The correct answer is no nucleus, no mitochondria and no endoplasmic reticulum.

Mature mammalian red blood cells (erythrocytes) are unique in that they lack most organelles found in other eukaryotic cells. They are anucleated, meaning they do not have a nucleus. They also lack mitochondria, endoplasmic reticulum, and Golgi apparatus.

The absence of these organelles maximizes the space available for hemoglobin, the protein responsible for oxygen transport. The lack of mitochondria means that RBCs rely on anaerobic respiration (glycolysis) for energy, ensuring that they do not consume the oxygen they carry. Their distinctive biconcave shape provides a large surface area for gas exchange.

This question was previously asked in

The correct answer is Renin.

Renin is an enzyme secreted by the juxtaglomerular cells of the kidneys. It plays a crucial role in the body’s Renin-Angiotensin-Aldosterone System (RAAS), which regulates blood pressure, fluid balance, and electrolyte balance. Renin initiates the cascade by cleaving angiotensinogen, a plasma protein produced in the liver, into angiotensin I.

Angiotensin I is then converted into angiotensin II, a potent vasoconstrictor and stimulator of aldosterone secretion, by the Angiotensin-Converting Enzyme (ACE), primarily found in the lungs. The RAAS pathway is vital for maintaining homeostasis and is a target for many medications used to treat hypertension and heart failure. Nitrogenase is involved in nitrogen fixation, Hydrolase is a broad class of enzymes that catalyze hydrolysis, and Mono-oxygenase is an enzyme that incorporates one atom of molecular oxygen into a substrate. None of these are directly involved in the kidney’s conversion of angiotensinogen.

Dengue fever is a mosquito-borne viral infection that can cause severe illness. One of the characteristic effects of dengue virus is its impact on blood cells, particularly platelets (thrombocytes). Dengue infection often leads to a significant decrease in platelet count (thrombocytopenia), which can increase the risk of bleeding.

Dengue virus significantly reduces the number of platelets in the blood.

While dengue can affect white blood cell counts (often causing a decrease in lymphocytes and neutrophils), the reduction in platelets is a hallmark of the disease and a critical factor in assessing the severity and managing potential complications like dengue hemorrhagic fever. Monocytes and eosinophils are types of white blood cells, and while their counts can fluctuate during infection, the primary clinically significant reduction targeted by the question is typically platelets.

Sleeping sickness, or African trypanosomiasis, is a parasitic disease caused by flagellate protozoa of the genus Trypanosoma. Specifically, Trypanosoma brucei gambiense and Trypanosoma brucei rhodesiense cause the disease in humans. The parasite is transmitted through the bite of an infected tsetse fly.

Sleeping sickness is caused by parasites of the genus Trypanosoma.

Histomonas meleagridis is a parasite that causes histomoniasis (“blackhead”) in poultry. Naegleria fowleri is a free-living amoeba that can cause a rare and fatal brain infection in humans. Angomonac is not a recognized parasitic genus.
