NEET BIOLOGY

Detailed explanation-1: -Thus, the correct answer is ‘Homopolar bonds in their proteins. ‘

Detailed explanation-2: -Blue-Green Algae are a type of photosynthetic bacteria consisting either of single cells or colonies which is also known as the Cyanobacteria. Cyanobacteria contain only one type of chlorophyll, Chlorophyll a, a green pigment. In addition, they also contain pigments such as carotenoids, phycobilin.

Detailed explanation-3: -Blue-green algae prefer warm, calm, sunny weather and water temperatures higher than 75°F. Blooms usually occur during summer and early fall, but can occur other times of the year, if conditions are right.

Detailed explanation-4: -Cyanobacteria, formerly known as blue-green algae, are photosynthetic microscopic organisms that are technically bacteria. They were originally called blue-green algae because dense growths often turn the water green, blue-green or brownish-green.

Detailed explanation-5: -Blue-green algae which grow in hot water springs (at about 70∘C) are Oscillatoria terebriformis, Oscillatoria brevis etc. These blue-green algae are also called thermophytes. The temperature tolerance of these algae is due to the presence of homopolar bonds in their proteins.
