In every trophic level, only 10% of energy is passed on.
Grass, with <span>30,000 kJ of energy, is eaten by a zebra.
Zebra then has 10% of 30,000 kJ from the grass, which is 3,000 kJ of energy.
Cheetah then eats the zebra, gaining only 10% of 3,000 kJ of energy of the zebra. Finally as conclusion, cheetah has 300 kJ of energy after having acquired the zebra.</span>
Answer:
the rhythm of heart contractions.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
An electrocardiogram (ECG) provides information about the rhythm of heart contractions.
Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
The protein components which reside on the red blood cell membrane and which determines blood type are THE ANTIGENS.
Antigens are proteins molecules which are found on the surface of the red blood cell, the antigens that are present in the cell determine the type of blood that will be present in the individual. There are four types of blood; A, B, AB and O. <span />
Answer:
Signal transduction
Explanation:
A signal molecule binds to a receptor.
A conformational change in the signal-receptor complex activates an enzyme.
Second messenger molecules are released.
Protein kinases are activated.
Target proteins are phosphorylated.can be defined as the process in which a physical or chemical signal is transmitted through a cell as a series of molecular events inform of protein phosphorylation are catalyzed by protein kinase and this ultimately result into a cellular response. However, the protein that is responsible for the detection of stimuli is commonly refers to as receptors or sensor.
The lymph system creates extra white blood cells.
