Answer and Explanation:
When a cell is freezed, it cytoplasm-which is mostly water- is frozen and its volume expands. In consequence, pressure inside the cell increases and that causes damage to the outer wall.
The same occur in an unopened softdrink when it freezes. The volume inside the container increases and the pressure increases. If this volume increment is not considered before freezing the liquid, it could cause the container damage or breaking.
Mitosis is responsible for the growth of a eukayotic cell. during mitosis a cell divides and to 2, unlike meiosis which divides in to 4. mitosis is the asexual reproduction of cells, such as hair ,skin and nail cells.
A, B, and C make no sense
A makes no sense because Methane is lighter than air, and so the Methane would stay higher in the atmosphere, so it would not seep into the ground, it would remain in the air.
B makes no sense because Burning fossil fuels causes air pollution by increasing the amount of carbon dioxide in the air. the only way that carbon dioxide could pollute water is if it is combined on a molecular level, plus carbon dioxide does not inhibit the process of water being evaporated by the sun.
C also makes no sense because Deforestation causes acid rain by increasing carbon dioxide not decreasing carbon dioxide in the atmosphere.
so therefore by elimination your answer is D
Answe choice is B - students 3 and 6 tested materials that are conductors of electricity
Explanation: conductors produce light basically so if the bulb lights that mean it is an conductor and the rest were not
Animal’s and Plant's circulatory system:
1. Animals have circulatory system for the transport of nutrients and waste and plants have vascular system for the exchange of gases and nutrient.
2. Animals have specialized circulatory systems like.ARTERIES,VEINS and CAPILLARIES.
3. IN PLANTS, they have bidirectional transport system…like FOOD prepared though PHOTOSYNTHESIS is transported to different parts of plant body through phloem..while minerals and water intake by roots r transported by xylem..
4. ANIMALS circulatory system works on presence of amount of blood.
5. PLANTS circulatory system works on availability OF resources.
