El hielo flota porque es menos denso que el agua líquida. Cuando se forma hielo, ocupa aproximadamente un 9% más de espacio del que ocupaba como líquido. Por lo tanto, un recipiente de 1 litro de hielo pesa menos que un recipiente de 1 litro de agua líquida y el material más liviano flota hacia
The answer is
B.)active transport
Answer:
<u>mitochondria; cytoplasm </u>
<u>Explanation:</u>
Remember, the main difference between the two types of respiration is that Aerobic respiration<em> relies on oxygen</em> to break down body fats and sugars into energy. While Anaerobic respiration <em>does not</em> require oxygen to produce energy from fats and sugars.
Thus, In living organisms, it is believed that Aerobic respiration takes place in the <u>mitochondria</u> inside cells while Anaerobic respiration takes place in the <u>cytoplasm </u>of a cell.
True Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract
1) - The coracobrachialis and pectoralis major muscles connect the humerus anteriorly to the scapula and ribs, flexing and adducting the arm toward the front of the body when you reach forward to grab an object.
- On the posterior side of the arm the teres major and latissimus dorsi extend and adduct the arm towards the scapula and vertebra when you pull an object down off of a shelf above your head.
- The deltoid and supraspinatus muscles run superiorly between the scapula and humerus to abduct as well as flex and extend the arm.
These muscles allow us to raise our arm in the air or swing the arm as in throwing a ball underhand.
2) cariac muscle makes up the heart, its involuntary, striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.
3) Smooth muscles are composed of elongated, spindle shaped cells and are commonly involved in involuntary motions. Skeletal muscles allow movement by being attached to bones in the body. Skeletal muscles control voluntary movements which can be consciously controlled.
4) Calcium is a crucial part of muscle contraction. The ionic element is released from muscles during contraction and relaxation. The release of calcium helps propagate the muscle contraction and relaxation stages. An adenosine triphosphate molecule stores energy that is released and used by energy-consuming reactions, such as muscle contraction, transmission of nerve impulses and formation of other molecules. ATP is found in cells and is made from the breakdown of food. It is composed of oxygen, hydrogen, phosphorus and carbon atoms. The energy in an ATP molecule is locked within phosphate bonds, which hold its phosphate groups together.
5) The muscle would neither contract nor relax if ATP was'nt there. It would stay in the same state because ATP is required for contraction as well relaxation of muscle. That is why dead bodies become very stiff.
