Answer:

See explanation below:

Explanation:

Lactose is found in milk. It is part of the reason milk tastes somewhat sweet since Lactose is a sugar. Anyone that consumes milk or anything with milk in it, will consume Lactose.

As for me, I plan on having some Ice-Cream later. Since there is milk in Ice-Cream, I will consume Lactose today.

Hope this helps! Have an Awesome Day!!

What is the sequence of travel by an impulse through the cardiac conduction system?
adoni [48]

The sequence of impulse through the cardiac conduction system starts from SA node passes to AV node to atrioventricular bundle fibers and finally to Purkinje fibers.

Heart is an organ that receives oxygenated blood form lungs and deoxygenated blood from different parts of body. Oxygenated blood is transported to different organs and deoxygenated blood is transported to lungs for oxygenation.

Now, to perform this transportation, the auricles and ventricles of heart contract and relax. In order to contract and relax, impulse generation is required, which begins at SA node or Sinoatrial node. It is also referred to as pacemaker of the heart. SA node contracts the atria and the impulse transfers to AV node or Atrioventricular node.

This is followed by transfer of impulse to atrioventricular bundle fibers which further passes it on to Purkinje fibres for ventricular contraction. Now the blood is sent to lungs and aorta as per it's oxygen status.

The coracobrachialis muscle originates on the __________.
Travka [436]

Answer:

Option C, coracoid process of the scapula

Explanation:

Coracobrachialis muscle is one of the essential muscles that is responsible for the movement of elbow along with biceps brachii and triceps muscles.  

The coracobrachialis arises from the coracoid process of the scapula. It assists the elbow in flexion and internal rotation. Musculocutaneous nerve passes through the Coracobrachialis muscle and terminates at the lateral end of the cutaneous nerve of the forearm. However, the Coracobrachialis terminates at the humerus and its medial surface

Hence, option C is correct
