Biology Test 126

Broca area also called convolution of Broca, a region of the brain that contains neurons involved in speech function. This area, located in the frontal part of the left hemisphere of the brain, was discovered in 1861 by French surgeon Paul Broca, who found that it serves a vital role in the generation of articulate speech. That's why after meeting an accident Anita became very poor in grammar and pronunciation.

Hence, the correct option is (D).

The grey nurse shark practice intrauterine cannibalism, or eating the other fertilized or unfertilized eggs in the womb. That's because as the sharks develop their embryonic teeth, they start to eat the other embryos, killing their unborn brothers and sisters, as well as the unfertilized eggs. The first developed embryo consuming both additional eggs and any other developing embryos.

Hence, the correct option is (A).

HBsAg (Hepatitis B surface antigen) - A "positive" or "reactive" HBsAg test result means that the person is infected with hepatitis B. This test can detect the actual presence of the hepatitis B virus (called the “surface antigen”) in your blood.

The diagnosis of HBV infection requires the evaluation of the patient's blood for HBsAg, hepatitis B surface antibody (HBsAb), and hepatitis B core antibody (HBcAb).

Hence, the correct option is (A).

Glycolysis itself does not use oxygen. Glycolysis itself is the splitting of glucose into two molecules of pyruvic acid. Glycolysis occurs in virtually all living creatures, including all animals, all plants and almost all bacteria.

Hence, the correct option is (B).

Chicory powder is a flavoring material, which is mixed with coffee powder (from seeds of Coffea Arabica). It is obtained from roots of Cichorium intybus of family Compositae. Tea is the dried leaves of Thea Sinensis (family Theaceae). Ephedrine is obtained from the stem of Ephedra gerardiana. It is useful against asthma and as a cardiac stimulant.

Hence, the correct option is (A).

Gamma-aminobutyric acid (GABA) is a naturally occurring amino acid that works as a neurotransmitter in your brain. Neurotransmitters function as chemical messengers. GABA is considered an inhibitory neurotransmitter because it blocks, or inhibits, certain brain signals and decreases activity in your nervous system.

Hence, the correct option is (C).

The cerebellum (which is Latin for “little brain”) is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for coordinating voluntary movements.

Coordination of voluntary movements: Most movements are composed of a number of different muscle groups acting together in a temporally coordinated fashion. One major function of the cerebellum is to coordinate the timing and force of these different muscle groups to produce fluid limb or body movements. Therefore, people drinking alcohol heavily have problems walking straight and driving.

Hence, the correct option is (B).

Himgiri is a wheat hybrid type, yielding 26–30 QLs per Ha. It is a disease-resistant variety that bites the rust or yellow rust. It is a triticum beautivum species. The variety was developed by IARI. HS-375 is produced in the considered / rainfed area. It is of moderate fertility and late-sown Hy of Himgiri, while HS375 is produced at very high altitudes in the northern Himalayas and the Garhwal region. There is resistance to Himgiri leaf and striped rust and mountain beak.

Hence, the correct option is (C).

Sexually transmitted diseases (STDs) are infections that are passed from one person to another through sexual contact. The causes of STDs are bacteria, parasites, and viruses. There are more than 20 types of STDs, including. Chlamydia. Genital herpes, etc. It is not the part of successful implementation while other options are in match with the statement given in the question.

Hence, the correct option is (C).
