Answer:
It is based on the size of seismic waves
Explanation:
Generally, the size of an earthquake is called its magnitude.
Earthquake’s magnitude is defined as the measure of the amplitude of the seismic waves. A seismometer or seismographs are used to measure seismic waves. So, the statement describes one aspect of an earthquake’s magnitude is that Earthquake’s magnitude depends on the size of seismic waves.
Earthquake’s magnitude is measured by the Richter magnitude scale.
Hence, the correct answer is It is based on the size of seismic waves.
The rocks near the mid-ocean ridge were younger then rock near trenches. Matching bands of magnetic rocks were found on either side of the mid-ocean ridge; bands like tree ring - record changes in earths magnetic field over time. Earthquake data showed oceanic crust is sinking on to the mantle at trenches.
The number of neutrons is the atomic mass minus the number of protons.
Explanation:
Firstly, humans have a double circulatory system, which increases blood pressure and flow of blood to the tissues. To allow the heart to pump blood around the body, the heart is made of cardiac muscle. These muscle cells have long protein filaments, which have the ability to slide past each other, shortening the cell and leading to contraction. In order to supply oxygen to cells the heart first pumps the blood into the lungs through the pulmonary artery. Here oxygen diffuses from the air in the alveoli into the blood. Blood then returns to heart via the pulmonary vein. It is then pumped out again, towards the rest of the body, through the aorta. Oxygen is then carried around the body by red blood cells. They are specialised cells, which have no nucleus and contain haemoglobin so that there is maximum space for oxygen. The circulatory system is made up of three types of blood vessels. The first type, arteries, carry the oxygenated blood to the tissues. The second type, capillaries, which have very thin wills and a large surface area to allow for easy and maximum diffusion, deliver the oxygen to the cells for respiration and therefore energy release. Waste products such as CO2 are then removed from the tissues, as they diffuse through the capillary walls and into the blood plasma. The third type of blood vessel, veins, then carry this blood back to the heart. Veins contain valves to keep blood flowing in the right direction and prevent back flow.
Answer:
The correct answer will be option-
Hydrogen (atom) →water (molecule)→ liver (organ) →skin (cell) →elephant (organism) → wolf pack (population) → tropical rainforest (ecosystem) →planet Earth (Biosphere).
Explanation:
The biological level of organization is the arrangement of the matter from the smallest to the largest in the hierarchy.
The smallest unit of matter is the atom which forms the molecules. These molecules together form the organelles which aggregate and form the basic unit of life called cell. The cells aggregate-gate and perform the same functions to form tissues which together form the organs. These organs constitute the organ system which forms the organisms. The organism together forms the population which form the community. The community becomes a part of the ecosystem which forms the largest level called the biosphere.
On the basis of this, the given options are arranged.
