<span>The planets are conserving that initial angular momentum. Now Uranus and Venus show opposite rotation. This is due to the impacts in the early years of their formation by asteroids and planetesimals. These impacts have probably reversed their rotational direction.

Answer:
Plants release oxygen into the atmosphere during the process of photosynthesis. In photosynthesis, plants make their food in the presence of sunlight. Water is extracted from the soil and carbondioxode enters through stomata and combine in the leaves of plants make glucose and oxygen. Glucose is stored in different parts of plant body and oxygen is released into the atmosphere which is used by living organisms.
Man abuses nature particularly its natural balance. Pollution has increased over time, disrupting our biosphere, hydrosphere and whatever else. Enhanced greenhouse effects which overly warms the planet and destroyed the atmosphere.
Most plantonic life in the ocean exists in an area that is very vulnerable to marine pollution. This area is called the nutrient-rich zone.
Answer: Option D
<u>Explanation:</u>
Most plantonic life in the ocean exists in the nutrient rich zone of the ocean. Sunlight is essentially the ultimate resource for the photosynthesis of these planktons. The photosynthesis is largely restricted to the upper layer.
Hence they are in the surface where the light penetration is available. This surface area is so rich in nutrients and hence called as the nutrient rich zone. The surface area is always active producing gases. The marine organisms biogenic sediments are all concentrated on the surface layer.
