The secret weapon of any insect that walks on water is in its body hair. Water striders and fishing spiders both have legs and bodies that are covered in a thick layer of tiny hairs. These hairs trap air in between them, repelling water and helping them keep the bugs afloat. If the insect were to get wet through, it wouldn’t be able to walk on the surface of the water anymore.
Ans.
The biodiversity of a coral reef ecosystem will be decrease if there is a decrease in coral reef population as most if the marine organisms, such as microbes, sea urchins, plankton, fishes, seahorses, along with larger animals, such as sea turtles, directly or indirectly depend on coral reefs. As seaweeds act as competitors of corals, overgrowth of seaweed population would decrease population of corals.
This will lead to a disturbance in coral reef ecosystem and decrease the ecosystem's biodiversity. Thus, the correct answer is 'option B). the overgrowth of seaweed would prevent light from reaching the reef.'
Choice #1 & Choice#4 I believe
Answer:
(A) A transform fault or transform boundary is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone.
(B) In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys.
(C) A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Benioff Zone.
Explanation:
In order for cells to function and survive, their organelles work together to carry out ... The Cytoskeleton of a cell consists of a network of protein fibres that give the cell ... bounding a ring of nine pairs of Microtubules with a single pair in the centre. ... which look similar to Undulipodia, but have a very different internal structure.
