Answer: Cells make up the smallest level of a living organism such as yourself and other living things. The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the cell is called the fundamental unit of life.

Phototropism, Gravitropism, Thigmotropism, <span>Hydrotropism and Heliotropism</span>
Answer:
1. polarity
2. hydrogen bonding
3. High heat capacity
4. Adhesion
5. polarity
6. surface tension
7. high heat vaporization
8. hydrogen bonds form a rigid and stable network
9. Water is a polar substance and fat is a nonpolar substance.
10. Cohesion
Explanation:
Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.
The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.
High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.
When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does not interact with fat because like dissolves like.
In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.
Without clean water, more than 1a million women lose their lives every year with sanitation-related hookworm, which causes maternal anaemia and preterm births.
<h3>What is the relation between hookworm and anemia?</h3>
In regions where hookworm incidence is greater than 20% and anemia prevalence is larger than 40%, routine preventative chemotherapy for pregnant women after the first trimester is advised, as was already mentioned. In places above and below this guideline threshold, a subset analysis of the effects of maternal hookworm infection on anemia was conducted. Pregnant women with hookworm infection had a higher likelihood of having anemia than pregnant women without hookworm, as would be expected in locations where the prevalence of hookworm is more than 20% P 0.001. Intriguingly, pregnant women with hookworm infection had a higher chance of having anemia with a cOR of 6.07, P 0.001, in regions where the prevalence of hookworm was less than 20%.

Explanation:
The Precambrian covers almost 90% of the entire history of the Earth. It has been divided into three eras: the Hadean, the Archean and the Proterozoic. The Precambrian Era comprises all of geologic time prior to 600 million years ago.
