Explanation

Low voltage QRS complexes in an ECG are typically seen in pericardial effusion.

This condition causes fluid accumulation around the heart.

It dampens the electrical signals and results in reduced QRS amplitude.

Explanation

When water vapour in the air condenses and accumulates around a dust particle near the ground, fog is formed.

Cloud of small water droplets near ground level that is dense enough to reduce horizontal visibility to less than about 3,000 ft (1,000 m).

Fog may also refer to clouds of smoke particles (smog), ice particles, or mixtures of these components.

Explanation

All important questions and Information Related to 'Photosynthesis"

Photosynthesis takes place in presence of the following light Only in sunlight from the sun

Photosynthesis takes place faster in white light

Photosynthesis occurs more in blue and red light rays

Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.

Green Light light is more important for photosynthesis.

As compared to photosynthesis, glucose is chiefly decomposed during Respiration

At the time of a Solar Eclipse, the rate of photosynthesis will: Decrease

In all plants, the major sites of photosynthesis are Leaves

In Photosynthesis reduction occurs in the Water

At night, when photosynthesis is stopped, plants Give off Carbon Dioxide.

Photosynthesis pigments are organized into clusters called thylakoid

The process of photosynthesis produces glucose and carbon dioxide

Explanation

Circinate vernation, a term in botany, describes the arrangement of young leaves in a coiled or spiralled manner, characteristic of fern fronds. This coiled structure, often resembling a crozier or fiddlehead, protects the tender growing tip of the leaf as it matures. 

Explanation

Autumn leaves appear red and yellow because carotenoids are revealed.

This happens when chlorophyll breaks down in response to less sunlight.

Shown is a colour photograph of bright red and yellow flowers with green stems and leaves.

Explanation

The living simple tissue that provides support to the growing parts of a plant is collenchyma.

Collenchyma is a simple permanent tissue.

The cells are thickened at the corners due to the deposition of cellulose, hemicellulose, and pectin.

It provides mechanical support to the young, growing parts of the plant.

Explanation

 Phylum Chordata is divided into three subphyla.

• Urochordata (Tunicata)
• Cephalochordata
• Vertebrata 

Explanation

Explanation

 Urial males have large horns, curling outwards from the top of the head turning in to end somewhere behind the head; females have shorter, compressed horns.

The horns of the males are up to 100 cm (39 in) long.

The shoulder height of an adult male urial is between 80 and 90 cm (31 and 35 in).

Explanation

 Zoological/botanical garden is not included under in situ conservation.
