Answer 1

1.  (CORRECT ANSWER) (MORPHOSPECIES CONCEPT)

(EXPLANATION FOR CORRECT ANSWER)

MORPHOSPECIES CONCEPT IS THE OLDEST SPECIES CONCEPT. IT DISTINGUISHES SPECIES BASED ON THE DIFFERENCES IN THEIR MORPHOLOGICAL CHARACTERISTICS. TWO OTHER SPECIES CONCEPT AND THEIR LIMITATIONS ARE AS FOLLOWS -

2. BIOLOGICAL SPECIES CONCEPT - DEFINES SPECIES AS MEMBERS OF A POPULATION THAT ACTUALLY OR CAN POTENTIALLY INETRBREED IN NATURE. IT TAKES NO ACCOUNT OF PHYSICAL FEATURES. ITS LIMITATION IS THAT IT EXCLUDED ASEXUAL ORGANISMS AS THEY DO NOT BREED.

3. PHYLOGENETIC SPECIES CONCEPT - DEFINES SPECIES DESCENDED FROM A COMMON ANCESTOR. ITS LIMITATION IS THAT IS CANNOT BE APPLIED FOR A LARGE GROUP OF SPECIES DUE TO LIMITED INFORMATION OF THEIR EVOLUTIONARY HISTORY.

2. (CORRECT ANSWER) (UNIFORM DISPERSION)

(EXPLANATION FOR CORRECT ANSWER)

INDIVIDUALS OF A POPULATION ARE MORE OR LESS EQUALLY SPACED APART.

3. (CORRECT ANSWER) (BIRDS)

(EXPLANATION FOR CORRECT ANSWER)

BIRDS ARE OVIPAROUS ANIMALS THAT IS THEY LAY EGGS WHICH HAS AN OUTER COVERING IMPERMEABLE TO WATER AND PERMEABLE TO GASES.

4. (CORRECT ANSWER) (BRYOPHYTES)

(EXPLANATION FOR CORRECT ANSWER)

(BROPHYTES ARE THE NONVASCULAR LAND PLANTS THAT DO NOT PRODUCE FLOWER OR SEEDS. BRAWN IN 1964 FIRST SUGGESTED THE TERM "BRYOPHYTA" FOR THIS GROUP. THE TERM BRYOPHYTE COMES FROM THE GREEK WORD, BRYON WHICH MEANS TREE MOSS AND PHYTON MEANS PLANT.

CHARACTERISTIC FEATURES OF BRYOPHTES ARE - 1. GAMETOPHTYE IS THE CHARACTERISTIC STAGE IN THE LIFE CYCLE

2. THEY HAVE UNBRANCHED SPOROPHYTES.

3. THEY LACK A WELL DEVELOPED VASCULAR SYSTEM
