Just like our skin helps protect us, leaves have an outer layer that protects them. This outermost layer is called the cuticle. It is generally waxy to protect the leaf and prevent water loss.
Answer: Mangrove trees are the trees that live in the coastal area. They are economically very beneficial.
- Mangrove tend to survive in water as they have submerged kinds of roots. This root provides anchor and the elevated roots being above water take oxygen from the atmosphere.
- They can also survive in haline conditions because they have special internal pumping mechanism that removes excess of salts from the cells.

Based on the data in the table (see attached image), the pair of organisms with two ecological relationships - competition and predation - would be hawks and snakes.
Looking at the table critically, hawks consume shrews and snakes. This makes hawks predators, while shrews and snakes are their prey.
In another instance, snakes consume shrews and, hence, are also predators on their own rights.
This means that the consumption of shrews is common to both hawks and snakes.
Hence, on one hand, hawks and snakes are in competition for shrews, and on the other hand, hawks also have the capacity to prey on snakes.

I believe it is D) heliocentric !
If this question has the same set of options like the previous ones, the answer to this question is letter<span> C. Median.
</span><span>A line connecting a vertex of a scalene triangle with the midpoint of the opposite side is the <span>median.
</span></span>A median of a triangle<span> is </span>a line <span>segment </span>joining a vertex<span> to the </span><span>midpoint of the opposite side.</span>
Here are the following choices:
A. altitude.
B. bisector of the angle at the vertex.
C. median.
D. perpendicular bisector of the side.
