Answer: c

Explanation:

A new study in mice and patients shows that atherosclerosis meets the criteria for an autoimmune disease.

About Atherosclerosis:

• It is a condition in which plaque builds up inside your arteries.
  • Arteries are blood vessels that carry oxygen-rich blood to organs and tissues throughout your body.
  • Plaque is a sticky substance made up of cholesterol, fat, blood cells, calcium, and other substances found in the blood.
• Over time, plaque hardens and causes your arteries to narrow. That limits the flow of oxygen-rich blood to your body.
• Some people may confuse atherosclerosis and arteriosclerosis, but they are not the same thing:
  • Arteriosclerosis is hardening of the arteries, which means that the arteries thicken and become less flexible. It can have several different causes.
  • Atherosclerosis, which develops from plaque buildup, is a common type of arteriosclerosis.
• What causes atherosclerosis?
  • Plaque often starts to build up during childhood and gets worse with age.
  • The exact cause is unknown, but researchers believe that this buildup happens when there is damage to the arteries. This damage may be caused by unhealthy lifestyle habits, medical conditions, and your genes.
  • Recent studies also point that atherosclerosis meets the criteria for an autoimmune disease.
• Atherosclerosis can affect most of the arteries in the body. It has different names, based on which arteries are affected:
  • Coronary artery disease (CAD) is plaque buildup in the arteries of your heart.
  • Peripheral artery disease (PAD) is plaque buildup in the arteries that carry blood away from the heart to other parts of the body. It most often affects the arteries of your legs, but it can also affect the arteries of your arms or pelvis.
  • Carotid artery disease is plaque buildup in the neck arteries. It reduces blood flow to the brain.
  • Renal artery stenosis is plaque buildup in the arteries that supply blood to your kidneys.
  • Vertebral artery disease is plaque buildup in the arteries that supply blood to the back of your brain.
  • Mesenteric artery ischemia is plaque buildup in the arteries that supply your intestines with blood.
• Symptoms:
  • Atherosclerosis symptoms often don’t start until an artery is very narrow or blocked.
  • Many people don’t know they have plaque buildup until they have a medical emergency like a heart attack or stroke.
  • Symptoms usually depend on the arteries that are affected, and the most common include:
    • chest pain (or angina)
    • feeling confused, as a result of limited blood flow to your brain
    • difficulty breathing
    • feeling very tired (fatigued)
    • pain in any of your limbs, where there may be a blocked artery
    • weak muscles.
  • Atherosclerosis can cause other health problems, or complications.
    • For example, if a plaque bursts, a blood clot may form.
    • The clot could block the artery completely or travel to another part of the body.
    • Blockages in different parts of the body can lead to complications such as a heart attack, stroke, vascular dementia, or limb loss.
  • Treatment: Treating atherosclerosis may include having a heart-healthy lifestyle and taking medicines.

Hence both statements are correct.

Answer: b

Explanation:

The Department of Animal Husbandry and Dairying (DAHD), Government of India, has taken proactive measures to strengthen the prevention, surveillance and control of Lumpy Skin Disease (LSD) in the country. 

• It is a viral disease affecting cattle and buffaloes.
• Cause and Transmission: It is caused by the Capripox virus and transmitted mainly through arthropod vectors.
  • Infected animals shed the virus through oral and nasal secretions, which may contaminate common feeding and water troughs.
  • Thus, the disease can either spread through direct contact with the vectors or through contaminated fodder and water.
• LSDV is not zoonotic, so humans cannot get infected by the virus.
• The disease is endemic in Africa and the Middle East and has been spreading increasingly in Europe and Southeast Asia over recent years.
• Symptoms:  The disease is characterised by fever and enlarged superficial lymph nodes on the skin and peculiar multiple nodules or lumps on the Skin.
• Treatment:
  • There is no treatment for the virus, so prevention by vaccination is the most effective means of control.
  • The infected animals receive supportive care, which involves the use of antibiotics, painkillers, and wound care sprays to treat symptoms.

Hence only statements 1 and 2 are correct.

Answer: d

Explanation:

Researchers have discovered a new species of lichen, Buellia maharajensis, in Mathikettan Shola National Park.

About Buellia maharajensis:

• It is a new species of lichen.
• It is the fourth lichen variety discovered within Mathikettan Shola National Park, Kerala.
• Features of Buellia maharajensis:
  • It is saxicolous lichen that grows directly on rock surfaces and was recorded at an elevation of approximately 1,351 m.

Key Facts about Lichen:

• A lichen is a symbiosis between different organisms — a fungus and an algae or cyanobacterium.
• The basis of their relationship is the mutual benefit that they provide each other. 
• The photosynthetic algae or cyanobacteria form simple carbohydrates that, when excreted, are absorbed by fungi cells and transformed into a different carbohydrate. 
• They also produce vitamins that the fungi need. 
• Fungi contribute to the symbiosis by absorbing water vapour from the air and by providing much-needed shade for the light-sensitive algae beneath.
• The composite body of a lichen is called a thallus (plural thalli); the body is anchored to its substrate by hairlike growths called rhizines.
• Lichens are found worldwide and occur in a variety of environmental conditions. 
• A diverse group of organisms, they can colonize a wide range of surfaces and are frequently found on tree bark, exposed rock, and as a part of biological soil crust.

Hence option (d) is the correct answer.
