Answer:
Progenies of batch I would not be labeled by 35S; progenies of batch II would be labeled by 32P.
Explanation:
Cephalization describes the process by which organisms develop a distinct head. The head of a cephalized organism contains a concentrated group of nerves, or brain, that controls the rest of the organism, as well as specialized organs for consumption and perception, like mouths, eyes and ears. Cephalized organisms exhibit a distinct division between parts of the body; they have a front, back, top and bottom. These animals comprise the bulk of animals that are encountered on a daily basis.

What textbook? Most of their power is from Hydroelectric dams (59% of it)
<span>Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.</span>
Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.
<span>The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.</span>
Answer:
The correct answer is D)
Cycle energy and matter to support the biosphere as a closed energy system
Explanation:
The earth as we know it is a closed energy system that is, matter cannot be introduced or removed from it. Sometimes, rare meterites enter into the system with minimal or no disruption.
Also, energy can enter and leave. The energy mostly referenced here is the sun.
Within the earths system, the lithosphere, hydrosphere, and biosphere materials and energy go through a cycle which helps to support life.
For example, water when heated up by the sun rises as vapour from the earth and oceans into the atmosphere where it cools and condenses. When it cools and condenses, it
, in the form of rain, comes down on the earth and oceans. As rain falls down to the earth and runs off the rocks, rocks are broken down into smaller fragments and soils. The hydrosphere comprises of all water bodies on earth. Besides the vapours which are evaporated from the same into the atmosphere, when volcanoes erupt they also send vapourised water into the atmosphere.
So because the earth is a closed system, a change in one sphere effects a change in others. An example is a change in the water cycle.
Cheers
