Barophilic prokaryotes
1 grow slowly in highly alkaline frozen lakes at high altitudes
2 occur in water containing high concentrations of barium hydroxide
3 grow and multiply in very deep marine sediments
4 readily grown divides in sea water enriched in any soluble salt of barium
Explanation:
C Barophilic prokaryotes also known as piezophilic or barotolerant prokaryotes, are microorganisms that thrive and multiply in high- pressure environments, particularly in the deep ocean sediments where pressure is extremely high.

The telomeres of eukaryotic chromosomes consists of short sequences of
1 thymine rich repeats
2 cytosine rich repeats
3 adenine rich repeats
4 guanine rich repeats
Explanation:
D The telomeres of eukaryotic chromosomes consist of short sequences of guanine rich repeats. These repeats are typically TTAGGG in vertebrates, including human. Telomere play a important role in protecting the ends of chromosomes from degradation and fusion, thus maintaining chromosomes stability during cell division.

The chief component of the middle lamella in plant cell is
1 potassium
2 calcium
3 magnesium
4 phosphorus
Explanation:
B The middle lamella is a thin, amorphous camenting layer that helps in the joining of two adjacent plant cells. The main component of the middle lamella is calcium pectate.

Extranuclear DNA (genes) are located in
1 lysosomes and chloroplasts
2 Golgi complex and ribosomes
3 chloroplasts and mitochondria
4 ribosomes and mitochondria
Explanation:
C Extranuclear inheritance or cytoplasmic inheritance is the transmission of genes that occur outside the nucleus. It is found in most eukaryotes and is commonly known to occur in cytoplasmic organelles such as mitochondria and chloroplast.
