Answer» Answer: 1. Bones Cartilage Bones are the hard, inelastic and a tough organ that forms part of the vertebral skeleton. Cartilage is a soft, elastic and flexible connective tissue that protects the bone from rubbing against each other. Bones are of two types: compact or spongy. Cartilage is of three types: Hyaline cartilage, fibrocartilage, and elastic cartilage. Bone cells are known as osteocytes. Cartilage cells are known as chondrocytes. Presence of blood vessels. Absence of blood vessels (nutrients are obtained through diffusion) The matrix is both organic and INORGANIC. The matrix is completely organic. Has deposits of calcium salts. May or may not have deposition of calcium salts. 2. Cartilage It is a thin, fibrous, flexible connective tissue, which is mainly found in the external ear, larynx, respiratory tract, and the articulating surface of the joints. These cartilages lack blood vessels; therefore, the growth and DEVELOPMENT of these tissues are slower compared to that of other tissues. Altogether, there are three different types of cartilages, namely:
3. Xylem Phloem Definition Xylem tissues are the tubular-shaped structure, with the absence of cross walls. This tissue resembles the shape of a star. Phloem tissues are tubular-shaped, elongated, structures with the presence of walls with thin sieve tubes. LocationIt is located in the centre of the vascular bundle . It is located on the outer side of the vascular bundle. FibresXylem fibres are smaller. Phloem fibres are larger. 4.botany, a stoma, also called a stomate is a pore, found in the epidermis of leaves, stems, and other organs, that CONTROLS the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening. 5.As it has to prevent water loss, as well as inhibit invasion of pathogenic microbes. The epidermal tissues serve as the barrier between the external environment and the body. Hence, epidermal tissues have no intercellular spaces. 6.The main function of xylem is to transport water, and some soluble nutrients including minerals and inorganic ions, upwards from the roots to the rest of the plant. Xylem cells form long tubes that transport materials, and the mixture of water and nutrients that flows through the xylem cells is called xylem sap. 7.Blood is considered a connective tissue for two basic reasons: (1) embryologically, it has the same ORIGIN (mesodermal) as do the other connective tissue types and (2) blood connects the body systems together bringing the needed oxygen, nutrients, hormones and other signaling molecules, and removing the wastes 8.Difference Between Simple And Complex Tissue. Simple Tissues Complex Tissues Nature of the Tissue Homogenous Heterogenous Example Parenchyma, Collenchyma, Sclerenchyma Xylem, phloem 9.Nervous tissue is the term for groups of organized cells in the nervous system, which is the organ system that controls the body's movements, sends and carries signals to and from the different parts of the body, and has a role in controlling bodily functions such as digestion. 10.Epidermis, in botany, outermost, protoderm-derived layer of cells covering the stem, root, leaf, FLOWER, fruit, and seed parts of a plant. The epidermis and its waxy cuticle provide a protective barrier against mechanical injury, water loss, and infection. hope it helped you friend if it helps you mark it as brainliestHappy learning |

12. Explain how animals in vertebrata are classified into further subgroups |
|
Answer» Answer: Animals in Vertebrata are classified into five classes: ... These animals have a dual mode of LIFE. In the larval stage, the respiratory organs are gills, but in the adult stage, respiration occurs through the lungs or skin. They lay eggs in water Explanation: Vertebrates are classified further into sub-groups on the basis of simple to complex forms of structures and their functions. EXAMPLES. Pisces, AMPHIBIA, reptilia, aves and mammals. 1. Pisces: They are aquatic, cold blooded animals. Their heart has two chambers. Their body is covered by scales or plates. They lay eggs and PERFORM respiration through gills. Their endoskeleton is made up of cartilage. e.g. Fishes. 2. Amphibians: They are cold blooded animals and live in both water and land. Respiration is through gills, lungs, skin. They have THREE chambered heart. e.g. Frogs. 3. Reptiles: They are cold blooded animals. They have three chambered heart and they breathe through lungs. e.g. Snakes. 4. Aves: They are warm blooded animal, oviparous vertebrates covered with feathers. They have a four chambered heart and perform respiration by lungs. e.g. Birds. 5. Mammals: They are warm blooded animal with four chambered heart. They are viviparous and possess characteristics like pinna and hair on skin and canine. e.g. Humans. |

How does the change in temperature, affect the time taken for the preparation of yogurt? |
|
Answer» Answer: Yogurt production is affected by the production technological conditions. INCREASE in the incubation TEMPERATURE (42-45ᵒC) resulted to increase in the coagulation of the milk protein present (induced by themophilic BACTERIA) and viscousity. This ALSO resulted in increased acidity of the yoghurt. |

Answer» The heart has four chambers: The right ATRIUM RECEIVES blood from the veins and pumps it to the right VENTRICLE. The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen. The LEFT atrium receives oxygenated blood from the lungs and pumps it to the left ventricle. The left ventricle (the strongest chamber) pumps oxygen-rich blood to the rest of the body. The left ventricle’s vigorous CONTRACTIONS create our blood pressure |

Breifly describe the structure and function of cell wall |
|
Answer» Answer: A cell wall is a rigid, semi-permeable protective LAYER in some cell types. This outer covering is positioned next to the cell membrane (plasma membrane) in most plant cells, fungi, BACTERIA, algae, and some archaea. Animal cells however, do not have a cell wall. The cell wall has many important functions in a cell INCLUDING protection, structure, and support. Cell wall composition varies depending on the organism. In plants, the cell wall is composed mainly of strong FIBERS of the carbohydrate polymer cellulose. Cellulose is the major component of cotton fiber and wood, and it is used in paper production. Bacterial cell walls are composed of a sugar and amino acid polymer called peptidoglycan. The main components of fungal cell walls are chitin, glucans, and proteins. The plant cell wall is multi-layered and consists of up to three sections. From the outermost layer of the cell wall, these layers are identified as the middle lamella, primary cell wall, and secondary cell wall. While all plant cells have a middle lamella and primary cell wall, not all have a secondary cell wall. Middle lamella: This outer cell wall layer contains polysaccharides called pectins. Pectins aid in cell adhesion by helping the cell walls of adjacent cells to bind to one another. Primary cell wall: This layer is formed between the middle lamella and plasma membrane in growing plant cells. It is primarily composed of cellulose microfibrils contained within a gel-like matrix of hemicellulose fibers and pectin polysaccharides. The primary cell wall provides the strength and flexibility NEEDED to allow for cell growth. Secondary cell wall: This layer is formed between the primary cell wall and plasma membrane in some plant cells. Once the primary cell wall has stopped dividing and growing, it may thicken to form a secondary cell wall. This rigid layer strengthens and supports the cell. In addition to cellulose and hemicellulose, some secondary cell walls contain lignin. Lignin strengthens the cell wall and aids in water conductivity in plant vascular tissue cells.

The net movement of molecules remain equilibrium when a cell is placedin . |
|
Answer» Answer: The net movement of MOLECULES remain in equilibrium when a cell is placed in isotonic medium. Explanation: An isotonic medium can be described as the medium in which the concentration of solutes is same in the call as compared to outside of the cell. As a result, the molecules do not move in or out of a cell. A change in the concentration of the solutes will cause the cell to LOSE its equilibrium and become either hypotonic or hypertonic depending on the change which occurred.
