Samples of the mineral pyroxene normally exhibit HARDNESS OF 5 TO 6.
Pyroxenes are a group of rock forming minerals, which are found in both igneous and metamorphic rocks. The mineral is composed of many elements including: sodium, iron, magnesium, calcium, manganese, zinc, lithium and other smaller ions. They are also usually found in volcanic lava.
The correct answer is: right ventricle
There are two types of blood circulation:
1. Pulmonary circuit or circulation is a system of blood vessels between the heart and the lungs. In pulmonary circulation, deoxygenated blood leaves from the heart’s right ventricle through the pulmonary artery to the lungs. Oxygenated blood from the lungs (CO2 is released and O2 is picked up during respiration) is transported through the pulmonary vein and returned to the left atrium of the heart.
2. System circulation than transports oxygenated blood from the heart’s left ventricle through the aorta and to the rest of the body. Oxygen-poor blood from all tissues is then returned through the veins back to heart.
All of the answers would be correct,
hope this helped!! <span />
B. It has a whip, like a tail
Explanation - Protists are unicellular organisms. Some multi-cellular organism might exist. Some protists have silica plated scales on their body surface like diatomaceous earth. They exhibit both type of respiration - aerobic and anaerobic. They mainly have parasitic mode of nutrition.
Protists also have flagella which they whip that in turn helps in their movement and this feature have made them to enter into the water body, example - euglena. Paramoecium have cilia on their entire surface that helps in their locomotion in water.
