Biology Test 132

Currently, the Genetic Engineering Approvals Committee, a body under the Ministry of Environment and Forests (India) is responsible for approval of genetically engineered products in India. If the bill is passed, the responsibility will be taken over by the Environment Appraisal Panel, a sub-division of the BRAI.

Hence, the correct option is (B).

The earthworm is hermaphrodite. Male Reproductive System: There are two pairs of tests present in the 10th and 11th segments. Female Reproductive System: One pair of ovaries is attached at the inter-segmental septum of the 12th and 13th segments. Ovarian funnels are present beneath the ovaries.

Hence, the correct option is (C).

It is well recognized that the primary immunoglobulin (Ig) of the newborn is the maternal IgG as this is the only IgG to cross the placental barrier. On the other hand, it is IgM which is synthesized by the newborn in the early postnatal period followed by IgA and IgG.

Babies are born with low levels of IgA. Then, as the weeks and months go on, a baby's immune system makes more IgA and the levels slowly rise. But, when a baby breastfeeds during this early period of life, he gets high levels of IgA from breast milk. Therefore, breast milk IgA is absorbed by the infant's small intestine for up to 6 months of life.

Hence, the correct option is (D).

Any of a class or subclass (Magnoliopsida or Dicotyledoneae) of angiospermous plants that produce an embryo with two cotyledons and usually have floral organs arranged in cycles of four or five and leaves with reticulate venation, called also dicot, compare monocotyledon. Therefore, wheat is not an angiospermous plant, clearly, the correct answer will be Dicotyledonae.

Hence, the correct option is (D).

The stopover behavior of migrant birds is influenced by their energetic condition, but also by extrinsic factors, including weather conditions and habitat attributes such as vegetation structure, microclimates, predation pressure, competition, and food availability. Therefore climatic changes is close to the explanation given before.

Hence, the correct option is (A).

Hence, the correct option is (A)

By the reaction of α-ketoglutaric acid with ammonia, through which of the process glutamic acid is formed. Reductive amination is the method of amino-acid synthesis in plants. In this method, α-keto glutaric acid reacts with ammonia (NH3) and forms the amino acid called glutamic acid.

Hence, the correct option is (A).

Marasmus is a disorder caused by a deficiency of food or protein. Marasmus occurs in infants below 1 year of age when they do not get sufficient mother's milk or weaning diet. Such infants are often provided with very diluted cow or buffalo milk. Marasmus babies have emaciated bodies with shriveled appearance, thin face, sunken eyes, wrinkled thin and dry skin, protruding ribs, reduced digestion, and frequent diarrhea.

Hence, the correct option is (D).

The chromosomes take various shapes during anaphase of mitosis because the position of the centromere is different in different chromosomes.

The paired centromeres from each chromosome have just begun to separate and the sister chromatids are being pulled apart by the kinetochore microtubules as they are shortened by the loss of tubulin monomers. These chromosomes appear V-shaped when observed during anaphase.

Hence, the correct option is (A).

Exanthema disease is a deficiency symptom of copper in the plant, produced by soil factors and brought about by soil microorganisms, as they attack the tissues. It causes the yield of gums on the bark and affects the fruit-bearing capacity of the tree. The most common symptoms of copper deficiency include a disease of fruit trees called 'exanthema' in which trees start yielding gums on bark and 'reclamation of crop plants', found in cereals and legume.

Hence, the correct option is (B).
