Answer: Higher concentration; Lower concentration.
Explanation: The food that we eat undergoes digestion and breaks down into smaller components.
These small components of the food needs to be absorbed first by the process of diffusion.
The water molecules along with the electrolytes are absorbed from an area of its higher concentration in the lumen is transported to area where its concentration is very low.
Hence, the correct answer is diffusion, which is responsible for the transportation of products from one place (higher concentration) to another parts (lower concentration)in the body.
Answer:
Start by introducing your topic. What are you learning about? How will it impact your life or the lives of others? Give some context, or background information, to your audience if it is an uncommon topic. Try not to explain anything about your experiment or the data that you collected. Share what you were trying to find out, what your problem was. Conclude it by introducing how you started to research.
Answer:
1) The correct answer would be A. it transfers carbon to the atmosphere as carbon dioxide.
Cellular respiration refers to the set of biochemical reactions take place in a cell in order to convert the energy of glucose into adenosine triphosphate (ATP).
The carbon dioxide is released as the byproduct of the process.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
2) The correct answer would be D. fermentation can occur without oxygen.
Fermentation is the process which occurs in oxygen is either absent or present in very less amount.
Thus, it enables the cell to survive when oxygen is not available.
For example, in humans, the muscle cells switch to lactic acid fermentation when oxygen supply is decreased during intense exercise.
It produces very less amount of ATP as compared to the aerobic respiration.
Answer:
3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water

Solution:
In children, it is easily found it can cause rickets. Rickets is a rare disease that causes the bones to become soft and bend. In adults, severe vitamin D deficiency leads to osteomalacia. Osteomalacia causes weak bones, bone pain, and muscle weakness.
It happens due to the lack of Calcium.
