The correct answer is b. Head movement → Inner ear receptors → Vestibular nerve → Cerebellum.
The balance and equilibrium of the body is maintained by inner ear in the human beings. The parts of internal ear which takes part in balancing and equilibrium are the semi-circular canals and the vestibule. On the movement of head, the otoliths are pull in the direction of gravity.
Answer:
1. Nucleotides
2. Amino acids
3. Amino acids
4. Glucose
Explanation:
All the above substance described are biomolecules. They are all polymers i.e. complex molecule bond together in a long repeating chain, made up of simpler subunits called monomers. The monomers of the different biomolecules outlined above are:
1. The nucleic acids, DNA and RNA carry genetic information and are made up of many NUCELEOTIDES. A nuceleotide is a chemical combination of a five carbon sugar (pentose), phosphate group and nitrogenous base. These nucleotides are arranged sequentially to form nucleic acids (RNA and DNA).
2. Myoglobin is a protein that binds oxygen molecules and is a polymer of AMINO ACIDS. Amino acids are the building blocks of proteins. They are arranged to form a 3D structure that determines the function of the protein.
3. Insulin is a protein hormone that regulates blood glucose levels and is a polymer of AMINO ACIDS. All proteins are made up of the amino acid but the protein's function is dependent on the 3D structure formed by the amino acid sequence.
4. Animals store energy in the form of glycogen, a carbohydrate made up of thousands of monosaccharide (GLUCOSE). Glycogen is a polysaccharide made up of many monosaccharide units. These units are glucose molecules that are multibranched to form the glycogen that stores mainly in the liver and muscles of animals.
Answer: Is a group of organisms of the same species that interbreed for example a group of robins in North America
Trong dạ dày được tách rời khỏi các chất thực phẩm khác. Trong ruột non, mật hoa tiết ra chất béo trong khi các enzyme tiêu hoá chúng. Các tế bào ruột hấp thụ chất béo. Các a - xít béo chuỗi dài tạo thành một cấu trúc lipoprotein lớn được gọi là một hạch nguyên tử có thể vận chuyển chất béo qua hệ bạch huyết.
