Answer:
Rocks
Explanation:
Geo means “earth.” The Earth’s geosphere (sometimes called the lithosphere) is the part of the Earth that includes all the rocks, minerals and landforms of the surface and interior that make up the Earth. It starts at the ground and extends all the way down to Earth’s core.
Plants need this waxy outer coating, also known as a cuticle, for a
variety of reasons. The cuticle keeps the important things the plant
needs in, such as water and carbon dioxide, and the things the plant
doesn't need, such as too much heat, out. It performs a few different
functions, including protecting the important cells needed for
photosynthesis.
Some charophytes are group of organisms should feature cell division most similar to that of land plants.
<h3>What is evolution?</h3>
Evolution is a process of change in a population through genetic variation over time. Evolution involves change over time and descents from common ancestor.
Types:
- Convergent evolution
- Divergent evolution

Primary consumers<span> only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as </span>heat<span>. You can probably see where this is going. Primary consumers are eaten by </span>secondary consumers<span>. An example would be birds that eat bugs that eat leaves. </span>Secondary consumers<span> are eaten by </span>tertiary consumers<span>. Cats that eat birds that eat bugs that eat leaves, for instance.</span>
Answer:
Steps in which blood travels through the heart from the time it enters from the systemic circuit until it returns to the systemic circuit are:
- Aorta receives the oxygenated blood from the left ventricle.And gives it to systemic arteries.
- Cells recieve the oxygenated blood and give out carbon dioxide laden blood.
- The superior and inferior venacava bring deoxygenated blood to the right atrium.
- The deoxygenated blood then moves into the right ventricle.
- Deoxygenated blood reaches lungs through Pulmonary artery.
- Left Atrium recieves blood from lungs through pulmonary veins..
- Oxygenated then moves into Left Ventricle.
- Aorta recieves the blood from the Left ventricle
Explanation:
There are Two types of circulation in human body; the pulmonary circulation and the systemic circulation.
In Pulmonary circuit the blood is pumped into the lungs from the right ventricle to the lungs through pulmonary arteries. In this circulation the blood gets oxygenated.
In Systemic circuit the oxygenated blood from the lungs is pumped into aorta by the Left ventricle so that it can reach the body tissues,
- This circuit also brings deoxygenated blood from the body to the Right atrium of the heart.
- Blood enters the systemic circuit when Aorta receives the oxygenated blood from the left ventricle.
- The oxygenated blood then flows into the systemic Arteries and reaches the body tissues.
- Cell consumes the the required oxygen and nutrients then adds carbon dioxide, hormones and waste material to the blood.
- The systemic veins collect the deoxygenated blood.
- The deoxygenetated blood from upper half of the body is carried by superior vena cava and the blood from lower half of the body is carried by inferior vena cava.
- Both superior and inferior vena cava bring the blood to the right Atrium.
- From the right atrium, the blood moves into right ventricle through tricuspid valve.
- The Pulmonary artery carries the blood from right ventricle to the lungs.
- After the carbon dioxide diffuses out and oxygen is added, the blood is taken up by pulmonary vein.
- The Pulmonary vein brings the oxygenated blood to the left atrium of the heart.
- The blood then moves into the left ventricle through the bicuspid valve.
- The left ventricle then pumps the blood into the Aorta through aortic valve returning the circulating blood to the systemic circuit
