Conservation is needed for biodiversity. If one organism (plant or animal) goes extinct it disrupts the food chain and the ecosystem forcing plants an area to go extinct themselves or to migrate. The greater the biodiversity the the healthier the ecosystem is and vice versa.
Answer:
Water is denser as a liquid than as a solid.
Explanation:
The property of water that makes icebergs float on is due to the fact that <u>water as a liquid is denser than as a solid</u>.
According to the rules of floatation,<em> a less dense substance will always float on a denser liquid because a body will always displace its own weight when placed in a liquid</em>. At room temperature, water as a liquid has a density of 1 g/cm3 but if the same water forms ice, the density would be 0.92 g/cm3. Hence, when ice is placed on water, it will float on it.
Answer: Both the pupil will constrict in response to the light shown into the pupil.
Explanation:
The papillary response can be defined as a reflex that is generated in response to the intensity of light falling on eyes, which either dilates the pupil or constrict the pupil.
This reflex will constrict the pupil when light will be shown on eyes so that less light can enter the retinal ganglion cells of the retina.
Thus, in this way the papillary response of both eyes will be same and both the pupil will constrict.
Hence, both the pupil will constrict together in response to the light falling on right eye.
Cold fronts<span> form when a cooler air mass moves into an area of warmer air in the wake of a developing extra-tropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. </span>Cold fronts<span> often follow a warm </span>front<span> or squall line.
