Answer:
The types of epithelia are classified by the shapes of cells present and the number of layers of cells
Answer: It converts carbon to oxygen
Explanation: During photosynthesis, plants create glucose and oxygen molecules
Answer:
C
Explanation:
Heat causes changes in the temperature of objects
Answer:
The answer is D
Explanation: This is because fungus are Eukaryotic unlike bacteria.
When the temperature reaches 0˚C (32˚F), the top layer of the lake freezes and turns into ice. In solid form, water molecules are less dense and thus ice floats on the top of the lake.
This solid barrier prevents any wind-induced mixing as well as protects the relatively warm water underneath. Furthermore, light is also blocked so that photosynthesis is inhibited during this period. As the lake water is separated from the atmosphere, no direct oxygen diffusion occurs.
All these factors together causes a more even distribution of nutrients and gases in a lake in winter.
