Eating Vitamin D enriched foods, Infancy , pregnancy increases calcium absorption.
Oxalic acid in spinach, Having a high fiber diet rich in phytic acid, being over 70 years old can decrease calcium absorption.
Why is Calcium absorption important?
It's crucial to have enough calcium in the blood that carries nutrients to the bones in order to avoid the loss of bone mass. Although milk and other dairy products are a great source of calcium, as we become older, our bodies require more calcium. Because many people stop consuming calcium-rich foods or beverages, like whole milk, due to dietary concerns, a calcium-rich dietary supplement is crucial. A daily calcium requirement of 1,200 mg is necessary for older persons.

Answer:
Parasitism
Explanation:
the parasite (tape worm) gains while getting food,but the host (dog) is suffering while get inflicted with illnesses
I would say it’s probably B or C
Answer:
Low solute potential
Explanation:
Solute potential is simply defined as a pressure that is implemented to a given solution from preventing the water flowing inward across a distinct semi-permeable membrane
. This is also known as osmotic potential.
On the other hand, the water potential can be defined as the potential energy that is attained by water per unit volume.
There is a relationship between the solute potential and the solute concentrations, where the concentration of solute is inversely proportional to the solute potential.
Thus, in the desert areas, some plant cells are comprised of high solute concentration which favors them to survive in the arid climate because they have low solute potential that helps them in reducing the loss of water.
Answer:
1. Cells are composed of chemicals and both the structure and function of cells are regulated by the basic principles of chemistry. true
2. Scientists have successfully sequenced the entire genome of humans but have not yet sequenced the entire genome of any other species. false
3. Living systems are the most complex chemical systems on earth. true
4. Living systems are governed by the same principles of chemistry and physics that govern non-living systems. true
5. Living organisms contain unique chemical elements which are not found in non-living systems. false
6. An input of energy is required to maintain the complexity of living systems. true
7. The energy conversions that take place in living systems are governed by the same laws of thermodynamics that govern non-living systems. true
Explanation:
Cells are the basic unit of life which differentiate a living thing from a non- living thing. Although a living system, is made of the same chemical elements from which a non-living t=might be made, yet they are different from the non-living things as living things carry out the seven basic principles of live.
All living things carry genetic material from which their genome is made. Scientists have currently been able to sequence the genome of humans as well as many other organisms.
