Q: How are electrons shared in covalent bonds? Read this paragraph and choose the correct option from the provided answers: In other covalent bonds, electrons are shared equally. These bonds are called nonpolar covalent bonds. Neither atom attracts the shared electrons more strongly. As a result, the atoms remain neutral in charge. The oxygen (O 2 ) molecule in the Figure below has two nonpolar bonds. The two oxygen nuclei have an equal force of attraction for their four shared electrons. Choices: - randomly - orderly - unequally - equally A:
equally

Read this paragraph and choose the correct option from the provided answers: The digestive system consists of organs that break down food, absorb nutrients, and eliminate waste. Choices: - lymphatic system - hormonal system - skeletal system - digestive system A:
digestive system

Q: Q: What is the transfer of thermal energy between substances called? Read this paragraph and choose the correct option from the provided answers: Heat is the transfer of thermal energy between substances. Thermal energy is the kinetic energy of moving particles of matter, measured by their temperature. Choices: - Permeation - Diffusion - Radiation - heat A:
A: heat

Q: What substance is created when a copper turns from reddish brown to greenish brown? Read this paragraph and choose the correct option from the provided answers: A: Another example of matter changing color is a penny changing from reddish brown to greenish brown as it becomes tarnished. The color change indicates that a new chemical substance has been produced. Copper on the surface of the penny has combined with oxygen in the air to produce a different substance called copper oxide. Choices: - rust - copper alloy - iron oxide - copper oxide A:
**Answer**
copper oxide

Q: Q: What supports the scapula, transmits the weight and forces from the upper limb to the body trunk, and protects the underlying nerves and blood vessels? Read this paragraph and choose the correct option from the provided answers: end is also anchored to the first rib by the costoclavicular ligament. The acromial end of the clavicle articulates with the acromion of the scapula at the acromioclavicular joint. This end is also anchored to the coracoid process of the scapula by the coracoclavicular ligament, which provides indirect support for the acromioclavicular joint. The clavicle supports the scapula, transmits the weight and forces from the upper limb to the body trunk, and protects the underlying nerves and blood vessels. The scapula lies on the posterior aspect of the pectoral girdle. It mediates the attachment of the upper limb to the clavicle, and contributes to the formation of the glenohumeral (shoulder) joint. This triangular bone has three sides called the medial, lateral, and superior borders. The suprascapular notch is located on the superior border. The scapula also has three corners, two of which are the superior and inferior angles. The third corner is occupied by the glenoid cavity. Posteriorly, the spine separates the supraspinous and infraspinous fossae, and then extends laterally as the acromion. The subscapular fossa is located on the anterior surface of the scapula. The coracoid process projects anteriorly, passing inferior to the lateral end of the clavicle. Choices: - bladder - pelvis - cranium - clavicle A:
A: clavicle
