94. Which one of the following is a transgenic plant
[A] Golden rice
[B] Hybrid carrot
[C] Joha rice
[D] Camellia sinensis
Explanation: Golden rice is a variety of rice (Oryza sativa) produced
through genetic engineering to biosynthesize beta-carotene, a
precursor of vitamin A.
95. Distribution of endemic species is
[A] cosmopolitan
[B] restricted
[C] global
[D] only in India
Explanation: Endemism is the ecological state of a species being
unique to a defined geographic location, such as an island, nation,
country or other defined zone, or habitat type.
96. Major ecological community of plants and animals extending
over large natural area is called
[A] biota
[B] bioregion
[C] biome
[D] biosphere
Explanation: Biomes are often defined by abiotic factors such as
climate, relief, geology, soils and vegetation.
97. Compared to blood our lymph has
[A] no plasma
[B] more RBCs and less WBCs

cells, especially lymphocytes, the cells that attack bacteria in the

98. The two gases making highest relative contribution to the
greenhouse gases are
[A] CH₄ and N₂O
[B] CO₂ and CH₄
[C] CO₂ and N₂O
[D] CFCs and N₂O
Explanation: Carbon dioxide is the principal greenhouse gas; other
greenhouse gases are methane, chlorofluorocarbons, and nitrogen
oxides.
99. ABO blood groups in humans are controlled by the gene I. It has
three alleles, i.e. Iᴬ Iᴮ, and i. Since, there are three different alleles,
six different genotypes are possible. How many phenotypes can
occur?
[A] Three
[B] Four
[C] One
[D] Two
Explanation: Since three alleles, possible arrangements are Iᴬ Iᴮ(
Blood group AB), Iᴬ i or Iᴬ Iᴬ (Blood group A), Iᴮi or Iᴮ Iᴮ (Blood Group
B), and ii (Blood group O). So for six genotypes, four phenotypes are
possible.
100. Peripatus is a connecting link between
[A] Coelenterata and Porifera
[B] Ctenophora and Platyhelminthes
[C] Mollusca and Echinodermata
[D] Annelida and Arthropoda
Explanation: Peripatus(The Walking Worm) is the connecting link
between Annelida and Arthropoda.
