Biyoloji Ödev Yardımı

Biyoloji öğrenmenin en zorlu kısmı, öğrencilerin biyolojinin mikroskobik dünyasını anlamalarını, hücrelerin içine nasıl girip genleri ve molekülleri nasıl keşfedeceklerini nasıl sağlayacaklarıdır. Ancak bilgi teknolojisinin gelişmesiyle birlikte, ne kelimelerin ne de resimlerin biyoloji konularını tam olarak açıklayamadığı durumlarda biyoloji ödevi yardımı önemli bir rol oynayabilir.

QuestionAI, çeşitli deneyler ve ilgili alıştırmalar dahil olmak üzere, yaygın biyoloji soruları yardımcısından temel olarak farklı olan, biyoloji bilgisini öğrenmenize ve uzmanlaşmanıza yardımcı olan bir çevrimiçi biyoloji öğrenme yazılımıdır. Burada, bilgi noktalarını öğrenmek ve anlamak için sığdan derine, katman katman deneysel senaryoları yeniden oluşturmak için deneyleri simüle edebilirsiniz.

6. __ structures are remained from osteons partially destroyed by osteoclasts during growth and remodeling of bone. A. Central canal B. Volkmann canal C. External circumferential lamellae D. Inner circumferential lamellae E. Interstitial lamellae 7. I. Blood vessels and osteoblasts invade the lacunae of the old cartilage. II. Bone marrow cavities and osteoid are produced. Which epiphyseal plate zone does this information belong to? A. Zone of resting or reserve cartilage B. Zone of proliferating cartilage C. Zone of hypertrophic cartilage D. Zone of ossification E. Zone of calcified cartilage 8. I. Signal is transmitted along the T tubules to the sarcoplasmic reticulum to trigger Ca2+ release fron terminal cisternae into the sarcoplasm. II. The released calcium ions bind troponin, chance i shape. This leads to moving of the tropomyosin on t F-actin and exposing the myosin-binding active sit and allow crossbridges to form. III. When the impulse stops, calcium ions are activ transported into the sareoplasmic reticul tropomyosin re-covers active sites and filam passively slide back to their relaxed state. IV. Binding actin produces a conformational chang the myosins, which pulls the thin filaments toward sarcomere center. V. ATP binds myosin heads and is broken down ADP and P. Myosin heads detach from thin fila and return to their prepivot position. What is the correct order in the contraction mecl of the skeletal muscle? A. I-II-III-IV -V B. I-II-IV-V-III C.

Fascia adherens-Desmosomes D. Zonula adherens-Gap junction E. Desmosomes-Gap junction

1. Hyaline cartilage is not seen in __ A. the articular surfaces of movable joints, B. the walls of larger respiratory passages (nose, larynx,trachea, bronchi).

It's found in attachments of certain ligaments.and in the pubic symphysis. C. Major collagen type in fibrocartilage is collagen type I. D. The relative scarcity of proteoglycans makes the matrix of fibrocartilage more basophilic than that of hyaline or elastic cartilage. E. Chondrocytes of fibrocartilage occur singly and in aligned isogenous aggregates 4. Which of the following is true about bone tissue? A. Osteoid is an uncalcified bone matrix. B. When compared with osteocytes; the flat-almond shaped osteoblasts have significantly less rER, smaller Golgi complexes, and more condensed nuclear chromatin. C. Osteoclasts play a major role in matrix production. D. Osteonectin produced by osteoblasts bind Ca^2+ with high affinity, which leads to local increase of Ca^2+ ions. E. Osteoclass originate mainly from the endosteum. 5. Which of the following is false about periosteum? A. Purkinje fibers binds the periosteum to bone. B. Osteoprogenitor cells are found in the inner layer of periosteum. C. One of the major function of periosteum is to provide a continuous supply of new osteoblasts for appositional bone growth or repair. D. Endosteum is considerably thinner than the periosteum. E. The outer layer of periosteum is dense connective tissue with collagen bundles, fibroblast and small blood vessels.
