Answer:
27 days
Explanation:
It takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. This is called the sidereal month, and is measured by our Moon's position relative to distant “fixed” stars. However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).
<u>Answer:</u>
<em>The intertidal zone is a region of extreme conditions and the organisms should have special mechanisms to cope up with the extreme conditions.
</em>
<u>Explanation:</u>
Low tides expose an intertidal zone to air while high tides cover the intertidal zone with ocean water. When exposed to air the intertidal region is <em>directly exposed to the sun and there will be high temperature. </em>
Thus the animals have to cope up with the extreme heat and also have to face colder environment when under the sea. <em>Since there is change in salinity the organisms have to handle this as well.</em>
Some animals with shells close their shell tightly to seal moisture. Animals like <em>snails and crabs have thick outer covering to prevent water loss by evaporation. </em>
Organisms like leaf barnacles cluster together to avoid individual exposure. <em>Animals like sea stars cling to the rocks to avoid being washed away by the waves.

Answer:
Mitochondrial proteins enter the organelle through channels formed by membrane proteins present in its inner and outer membranes.
Explanation:
All the biological membranes have lipid bilayer with the non-polar core that does not allow entry of charged and large substances. Mitochondrial proteins are synthesized in the cytosol and the unfolded proteins bind to the chaperons that deliver them to the receptors present in the outer mitochondrial membrane.
The receptor moves the protein to the membrane channels formed by integral membrane proteins of inner and outer mitochondrial membranes. The proteins enter the intermembrane space and are targeted to the inner membrane through channels while chaperons are left outside only.
Answer:
1/(5⁹) or 5⁻⁹
Explanation:
This is a Mathematics question rather than a Biology question.
The given fraction is:
This fraction can be rewritten as:
Therefore, the quotient of the given fraction is 1/(5⁹) or 5⁻⁹
