Answer:
Crystal form refers to the geometric shape of mineral crystals. Crystal form is caused by the symmetrical, three-dimensional arrangement of atoms inside the mineral.
Explanation:
False
<span>Marine ecosystems like lakes and oceans have aphotic zones. Aphotic zones refer to the zones in the water where there is little or no sunlight. It is found in bodies of water were depths only receive less than 1% of sunlight penetrations. Bioluminescence is essentially the only light found in this zone and most food comes from dead organisms that sink at the bottom of lakes or oceans. </span>
Answer:
Vision
Explanation:
Sensory cells may detect the information like taste, touch, hear and vision by the presence of receptors located on their surface.
Hyperpolarisation may be defined as the change in the cell's membrane potential towards more negative. The sensory vision cells are associated with the hyperpolarisation of cells and makes the cells environment more negative in response to the stimuli.
Thus, the correct answer is option (d).
Answer:
Atmosphere, plant, animals, fossil fuels.
Explanation:
Carbon Is the essential elements needed for life.
Carbon cycle is the movement of carbon from the atmosphere to the Earth.
Carbon move in the carbon cycle and start from the atmosphere.
In the atmosphere, carbon react with oxygen and it is inform of carbon dioxide. Plants use the carbondioxide along with water,and uses light energy from the sun to produce carbohydrates through a process of photosynthesis.
Animals get carbon from plants after consuming plants.
During respiration, carbon atoms are released to the atmosphere.
Some human activities like burning of fossil fuels releases carbon to the atmosphere.
The types of rock that can form sediment when they are weathered is D. Igneous, sedimentary and metamorphic. (When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks. The sedimentary particles from which a sedimentary rock is formed can be derived from a metamorphic, an igneous, or another sedimentary rock. All three rock types can be melted to form a magma.)
