Answer:
the answer is C
Explanation: The deep ocean circulation of water is caused by convection currents in water that allow cold water to rise and warm water to sink.
Answer:
the sun
Explanation:
The typical lunar eclipse happens when the Sun, Earth and moon are all aligned 180 degrees apart from each other in the sky. When this happens, the Earth casts a shadow onto the moon, so the Sun should not be visible at all if you can still see the moon.
Answer:
Option (D).
Explanation:
Skeletal muscles is one of the most important types of muscle that regulate the contraction of skeletal muscles of the body. The skeletal muscle is controlled by the somatic nervous system.
Skeletal muscles are multi nucleate contains large number of nucleus in their structure. The multiple nucleus increases the ability of muscle to produce large number of enzymes. These enzymes are proteins are important for the muscle contraction.
Thus, the correct answer is option (D).
Answer:
Hydrogen Bonds
Explanation:
The arrangement of phospholipid bilayer of plasma membrane is such that ; the polar phospholipid heads point outwards into the watery external environments. This Polar environment is Hydrophilic or water loving, while the water- hating hydrophobic tail region pointed inwards away from the watery medium.
This gives the usual bilayer shape to the plasma membrane,with the tail facing one another and heads outward.
The hydrogen bond is formed as inter molecular forces between the hydrogen atom (positive side)of water molecule and oxygen atom (negative side)of the polar molecules e.g glucose, to form an idea dipole -dipole force interactions,
Polar Compounds, glucose, urea dissolved easily in hyrophilic watery environment to from Hydrogen bonds with water
<u>The correct answer is Hydrogen bond a dipole dipole force</u>
