Answer:
Nodes
Explanation:
A node is a stem zone where the leaves are attached, the stem portion between nodes are called internodes, the thricomes are like little hairs in the leave and the lenticels are spaces in the leave that helps to transpiration like the stomata.
So, the stem regions at which leaves are attached are called nodes.
Also the name nodes is really common in gardening, it helps a lot to identify which leave are they talking about.
The correct answer is option A, that is, placer deposits.
The concentration of heavy deposits known as the placer deposits are produced by the gravitational action, generally found in streams. The minerals that take place as placer deposits comprise copper, gold, magnetite, cassiterite, and copper.
The formation of placer deposits takes place when the metal-bearing rock on land is weathered and the generated debris is washed down to the sea by the rivers. Further by the action of waves, currents, and rides the particles of heavy metal gets amassed to produce mineral sand deposits. These generally occur as beach deposits.
Answer:
Reflected ray
Explanation:
The angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface is the angle of reflection.
Both X and Z will increase in order.
Option D.
<h3><u>Explanation:</u></h3>
Here in the question we can see that all the three compounds X Y and Z are in equilibrium as they are put in a water beaker containing water. This phenomenon is Called chemical equilibrium when the substances that are isomers to each other actually forms in water and their relative concentration remains in a particular ratio according to their stability.
Here in the question, the solution contains X Y and Z in equilibrium. But if more Y is added in the solution, firstly the equilibrium constant for X and Y will get disrupted because X will get low in amount with respect to Y. So some Y will get converted to X. Similarly, when Z will also face the same problem and some Y will get converted to Z. Hence the amounts of both X and Y will increase along with Y.
Answer:
The sun is classified as a star.
Explanation:
The sun is a star at the center of the solar system.
The sun is important in the following ways:
- The sun's light has to be present for photosynthesis to occur thereby, it enables food production by plants.
- The sun lights up the earth through its light rays.
- It warms up the sea.
- It provides heat for heating up the earth leading to production of water vapor that rises to form clouds.
- The sun also provides vitamin D that is essential to living organisms health.
